Affordable solar homes – a solution for homeowner poverty & net-zero housing!

Posted on by



Net-zero architecture is what will reduce emissions from the construction industry on a large scale. But make it inclusive as well as scalable and you also get a solution that can lift homeowners out of poverty while building a community! Created for that very purpose, these solar homes are aiming to help solve both the global housing and climate crises with one design. The houses produce their energy, harvest 100% of the rainwater, clean their sewage, and also have the potential to grow their own food!

It is called the PowerHYDE housing model and was created by Prasoon Kumar and Robert Verrijt of Billion Bricks from India and Singapore. The model explores sustainable solutions to empower and facilitate growth opportunities for people without homes around Southeast Asia which has a lot of rural and low-income populations. These homes not only provide shelter but are also a power module to scale sustainable communities that lift homeowners out of poverty!




“A BillionBricks Community is the world’s first carbon-negative solar home community to bring families out of poverty within one generation. PowerHYDE homes are plug-and-play modular structures that do not need any connection to services and could be made functional from the day of completion of construction,” says the design team. The cost-effective solution even won a Holcim Award for Sustainable Construction!

The PowerHYDE homes are built via an indigenous prefabricated technique that makes them easy to assemble in remote locations. The home has a solar array installed on the roof and the homeowner can sell excess power generated back to power companies, generating a profit that helps to pay off the cost of the home. Sample homes have been built in Mathjalgaon Village in India and in the Philippines. BillionBricks now plans to build a community of 500 homes near Manila, Philippines that will generate 10 megawatts of power.

Not only does it reduce the emissions from the construction industry (which is the leading contributor in the world for CO2 emissions) but it also helps more people become homeowners while equipping them with means to create renewable energy thus reducing individual carbon footprint as well. It is a radical concept in housing designed for energy sufficiency, extreme affordability, and education for future generations to adapt to a sustainable lifestyle even in rural areas.

This modern tiny home is all about harvesting & using water sustainably!

Posted on by

Sustainable architecture is how we can make a large impact on the collective carbon footprint as residents and also for the construction industry which is the leader for carbon emissions. The more sustainable structures we have, the faster we can take bigger chunks of carbon away rather than just using less plastic for one essential item. Wai House is a perfect example of that, ‘wai’ means water in Maori and that is the core of this modern home‘s design.

The modern architectural concept is designed to be built in New Zealand and focuses on collecting water and using it sustainably. The house itself is constructed with sustainable materials, cedarwood is used for the exterior cladding and the interiors use concrete with recycled plastic instead of sand. It has an almost Japandi-inspired aesthetic which is elegant enough on its own without taking away from the environment it is in.

It is designed to collect and store rainwater for use with systems in place that funnel it to the kitchen, bathroom, and outdoor greenery. Since it is just a concept, there is potential for it to become even more sustainable by adding solar panels for energy efficiency. New Zealand also has a rich cultural heritage and that can be incorporated into the interiors through the fabrics used or the artwork to foster a stronger bond with the local community and give back to them.

Wai House is perfect for a young couple who is willing to leave the traditional living standards and move to a smaller, yet spacious tiny home. With a smaller floor area compared to a traditional townhouse, the carbon footprint is also smaller and more so with the eco-conscious construction materials used. Wai House is also one of the noteworthy entries for the Green Product Award 2021 and we can see why – it perfectly blends minimalism, luxury, and sustainability into one compact home!

This floating farm turns salty seawater into nutrients for agriculture & improves marine environment!

Posted on by

A Japanese start-up has designed this floating marine farm called Green Ocean using agricultural technology that cultivates seawater as a direct nutrient source! The innovative structure combines salt-resistant technology and sea-friendly architecture to the world a potential solution for the climate change-induced rising sea level problem which comes with heavy salt damage. It harvests rainwater, improves the quality of the water around it, helps with food production while saving water and being a sustainable architectural structure.

Sea level rise is getting progressively worse due to climate change which affects agriculture heavily – it means less land to farm on and also damage to coastal land because of excessive salt. N-ark has developed Green Ocean in partnership with Cultivera which is an agrotechnology R&D company that aims to build the prototype of the floating marine farm by 2022. Seawater agriculture is a special cultivation method that absorbs water and nutrients in the ground and air by mixing and neutralizing alkaline seawater and acidic rainwater. As a result, a huge variety of vegetables can be grown by utilizing the minerals and nutrients contained in seawater!

Green Ocean is a floating, solar-powered, salt-resistant greenhouse constructed with thinned wood and carbon joints. Once it is out on the water, the marine farm will create two new green areas – one will be a food production space that floats on the surface and uses salty agricultural technology and the second will be a layer of algae that will improve the underwater environment. It has a distinctive angular roof that helps to collect rainwater which is then mixed with seawater and used as fertilizer for the plants. Cold seawater is also used for air conditioning within the farms. “By creating a cyclical system environment, Green Ocean plays the role of an adhesive plaster of the Earth,” explains the team.

The basic technology behind seawater agriculture is ‘moisture culture’ which allows cultivation under humidity control. With this method, about 15 cm of the surface layer of natural soil can be reproduced with a special fiber of approximately 5 mm, and vegetables with fortified sugar content and vitamins can be grown by evaporating water with the special fiber by applying water depletion stress to plants. Moisture culture uses one-tenth of the water that is needed in conventional irrigated farming methods and can be applied even in areas where water is not abundant making it a sustainable way to farm at scale.

This concrete bench collects rainwater for plants that are a part of the seating!

Posted on by



Concrete jungle is not just something Alicia Keys sang once, cities are becoming more paved with every passing day leaving scarce patches of greenery. Having concrete structures everywhere is not appealing to the eye but at the same time makes it harder for cities to use rainwater because they don’t have surfaces to absorb it. This makes it harder for them to maintain natural public spaces and green starts turning to gray. To solve this problem, Barbara Standaert made the Waterbench – it is exactly what you think. The design combines a bench, a rainwater barrel, and a planter into one to restore some greenery into the urban landscape.

Rainwater is used in public spaces to create self-sufficient green. The permanent water supply always guarantees a dry seat, even in rainy weather, requires hardly any maintenance, and ensures a permanent green touch in the city.

The rainwater naturally seeps through the porous concrete cover and is collected in a water-tight concrete reservoir where the plants find their water and food. The water is naturally absorbed and transported to the plants by a nylon cord. The Waterbench Rainwater buffer + water reservoir for plants Cover made of permeable concrete Collection trough in architectonic concrete water reservoir: +/- 280 liters.

Length 250 cm, Width 174 cm, Height 45 cm Weight: +/- 1,300 kg for the collection tray, +/- 1,100 kg for the cover. It is available in grey, other shades possible upon request. Overflow, allowing water to escape if the tank is full. The element rests on rubber stands, allowing excess water to run off. Another advantage of the Waterbench is the option to ‘plant’ the bench with little prior effort, in line with the particular needs of the environment.

Starting with the design question “How can we restore natural processes and give back some green to our urbanized landscape?” – I started researching what is being done today to direct rainwater to nature. Porous rainwater pipes were one example. The material fascinated me. I brought it to the surface to show what it did to the audience. After this, the function to combine the material and water storage with greenery was quickly made. During my studies I made the prototype all by myself. I carved out the some mold by using my football shoes. I filled the mold in cooperation with a concrete manufacturer and transported the (way too heavy) concrete block in a rented van. One day before the jury, I still had to apply the porous top layer… After I graduated I found a manufacturer who is now producing the market suitable Waterbench.

Posted on by



Do you also think about living in a modern luxury villa that is also a yacht powered by solar panels so you can lead the ultimate sustainable lifestyle of your dreams? Me too, and lucky for us (if being lucky also includes the $5.5 million base model cost) Waterstudio.NL and a Miami-based shipping company called Arkup have designed this insane dreamboat – literally! Called the Arkup 75, this flagship product combines luxury with off-the-grid living.

Arkup 75 lets you live in comfort and luxury in total autonomy – enjoy life between the sea, the sky, and the city. The 75 feet long yacht has a total living space of 4,350 sqft!

Arkup is a game-changer for the hospitality market when it comes to self-sustainable, blue developments. floating and overwater eco-resorts a reality with the versatility to scale, configure, even relocate. “We are revolutionizing life on the water. We leverage Arkup products and expertise for fast deployment, modular, floating communities that you scale according to market demands,” says the team.

The livable villa has 4 bedrooms, 4.5 bathrooms, a giant living space, a spacious kitchen, and a sliding deck all divided between two levels. It also has a rainwater harvesting system and solar panels so let you live off the grid comfortably!

Arkup livable yachts combine the best attributes of yachts, floating houses, and waterfront villas, with the added benefits of being self-sufficient, sustainable, and environmentally friendly. The Arkup livable yacht was conceived to be “future-proof”, from its ability to withstand or avoid extreme weather events to its self-contained systems that allow fully off-the-grid living.

The base model will cost $5.5 million and will come with the core amenities as well as the furniture but if you want a fully specced out version, the Arkup 75 can go well up to $10.5 million!

It is built to be energy efficient and incorporate a sustainable lifestyle with technology and systems in place like multiple solar panels on the roof and an intricate rainwater harvesting system with two 4000 gallon water tanks.

It also is modular and has stilts in case you want to dock your luxury home in the shallow waters of a remote island instead of drifting along the skyline of a big city.

This sustainable modern house provides food, water, power & protection for 100% off-grid living!

Posted on by

This airy modern home features lush gardens, solar panels, and a recycled water system to make living 100% off-grid home possible with style! Architect Rodolfo Tinoco designed Casa Jardin to be so well equipped that it fend for itself in any situation. It has all systems in place to provide food, water, power, and shelter during natural disasters. The unique structure has several details that help reduce its environmental impact, promote a sustainable lifestyle and provide plenty of privacy if you are on a vacation (that’s also why it’s conveniently located by the beach)!

Casa Jardin is built just one block from Tamarindo Beach which is Costa Rica’s main tourist destination. It is a blueprint for self-sustaining architecture. “I wanted to create a prototype that would provide food, water, and power, and also protect during catastrophic situations like droughts and floods,” said architect Rodolfo Tinoco who designed the home for himself and his family.

A vertical garden on the main facade wraps itself upwards and around the home. This creates privacy from the adjacent road, helps control the temperature of interior spaces, and grows edible greens – all factors that help make the home more sustainable and cozy!

The residential area is one level above ground and is spacious for a family with a sleeping area, large living room, bathroom, and a giant balcony where the vertical gardens continue to grow.

The home is set atop V-shaped stilts, reducing its impact on the land while also creating a covered outdoor space below. But raising it was also a way to plan for the changing climate: “Elevating the structure addresses the fact that our sea level is actually rising and properties will have to deal with this in the future,” explains Tinoco.

It features a leaf-shaped photovoltaic roof that harnesses enough solar power for the family to live off-grid. Rainwater from the roof is recycled for irrigation, as is the water produced by the HVAC system. Sewage is fully treated and drained into the property’s natural water flow. “Water is our most valuable resource, and this project shows it’s possible to use and reuse it efficiently,” explains Tinoco.

Casa Jardin’s interiors feature a neutral color palette that helps keep an emphasis on the natural environment outside. A teak wood ceiling, light gray porcelain tile, and whitewashed walls combine to create a naturally illuminated space. It is also inspired from a beachy aesthetic and visually keeps the space light, refreshing, and open!

Casa Jardin engages holistically with its surroundings and stands as just one example of LSD’s greater mission -“We’re committed to creating architecture that responds to the immediate context in our tropical climate while also being reflective of each owner’s unique needs,” says Tinoco who is an example himself, showing us all that sustainable living is possible with a family and without compromising on any luxuries!

This sustainable, self-sufficient, prefab house can be flat-packed & it looks like a cruise ship!

Posted on by




When you can’t go on a cruise, you bring the cruise home – literally! The Sail House is a spacious, self-sufficient, nautical-themed home with a unique form inspired by large white sails on ships. It is designed by Los Angeles-based architect David Hertz who is celebrated for sustainable architecture. Sail House was also selected as the 2021 Architizer A+Awards Jury Winner for Residential/Private House!

Sail House has a central structure called the main house with several guest houses bordering it and all nestled on the lush Bequia Island in the Caribbean – didn’t I say it literally brings a cruise home? Since the Caribbean is a notoriously difficult area to source building materials, the team made sure that the entire project – the main house and the guesthouses – were prefabricated offsite, flat-packed, and delivered in 15 shipping containers. This ensured minimal site impact to the sensitive ecosystem and was nearly zero waste which is important because otherwise, the construction waste would have had to be transported out of the island which would increase emissions.

The luxurious home was named after its eye-catching tensile roofs inspired by the history of sailing on the island. “The main inspiration for the Sail House was a wooden boat with its masts and sails, the expressed stainless steel rigging and hardware, which is referenced in the home,” said Hertz. The roof membranes also act as a rain collection system by funneling water into a concrete foundation for storage. This nifty system provides for 100% of water needs and the air pulled from the stored water is then used to cool the space when needed. Additionally, the cantilevered roofline provides more shade and ventilation to increase cooling naturally. The electricity needs are covered by solar panels.

Both the interior and exterior of Sail House include natural construction materials such as woven palm, coconut shell fragments and surfaces crafted by Javanese and Balinese artisans. “Sustainability was one of the main goals of the Sail House project. The non-corrosive and termite-resistant aluminum structural system is wrapped in reclaimed ironwood planks recycled from an abandoned pier in Borneo, as are the plank floors, decks, and the vertical louvers that control low sun and prevailing breezes,” Hertz explained. It is truly one of the most beautiful, resilient, and functional homes I’ve seen that flawlessly balances luxury with sustainability!

This tiny house is actually a clean energy powered, self-sufficient, repurposed shipping container!

Posted on by




We are adding Gaia by Pin-Up Houses to our list of the most incredible tiny houses! Gaia is a discarded shipping container turned into a cozy, self-sufficient home fitted with the latest technology to match your modern lifestyle. It was designed to be an alternative solution to traditional housing and reduce the negative impact on the environment.

One of the main features of the experimental off-the-grid housing project is that it harvests solar and wind energy. Gaia doesn’t rely on external sources of energy or water which is vital in the current climate crisis as well as the future. It comes equipped with solar panels and a wind turbine so the batteries will be fully charged at any time of the day and during all seasons. You can monitor the battery levels through a mobile app even if you are on the go. The tine home has been designed inside a marine HC 6 m container featuring wooden studs and spruce plywood in the interiors. Another clever detail is the container’s roof which covered with a galvanized corrugated metal sheet that extends out beyond the structure. This increases the rainwater collection and is stored in a 1000-IBC tank

The rainwater is then filtered and distributed to the bathroom and kitchen through the house’s systems. Gaia comes with a refrigerator, water heater, and other 12 V and 24 V appliances based on your needs. If your appliance needs a higher voltage of 110 V to 230 V, it can be generated using an inverter. Pin-up Houses has also maximized the limited area by including compact storage, a convertible sofa-bed, space-saving stools, and tables. The outdoor terrace can also be folded to close the container using the winch, this way you can have your privacy.

All the walls inside are sprayed with thermal insulation (spray foam) making sure it is habitable all around the year and not just treated as a summer cabin. However, spray foam is also highly combustible fossil fuel. But to ensure safety, the woodstove is properly shielded with steel on the floor and behind. The team has also made sure to include a lot of exit points. Another point to note for the environmentally cautious residents is that the bathroom is a bathroom – a Porta-Potti style chemical toilet where the bottom half is a suitcase full of waste and formaldehyde chemical which has to be taken elsewhere to be safely discarded.  This could be fixed up by swapping it for a small compost-friendly toilet to further reduce the environmental impact of the house.

The container is pretty spacious despite its size and doesn’t feel cramped or claustrophobic for the residents with how well each corner has been utilized for maximum functionality. Gaia is modern, self-sustaining, and economical for those looking to lead a more sustainable lifestyle while also being homeowners with enough savings leftover after their investment. It is still a prototype so a lot of the systems can be improved to make them more sustainable. Ten extra points for the wonderful draw-bridge style deck!

This 100% self-sustaining cabin is was placed in the forest without a trace of fossil fuels!

Posted on by

You know my love for cabins and sustainability, I am always searching for the best cabins to go live in once the pandemic is over and sustainable designs that can help slow down the climate crisis. I finally found a design that marries them both and this is the most perfect cabin to exist on my list – a 100% self-sustaining and sustainable off-the-grid cabin that focuses on enjoying as well as preserving the environment it is in! They invented an assembly architecture that is fully adaptable to the environment and doesn’t even need a boom truck to be transported because of the construction technology (through assemblies) – the team takes the materials anywhere even when the construction site is far from the car path.

The latest cabin by the company is called Krul and is developed to perform independently of passive systems. The interiors are designed in a way to allow maximum natural sunlight, especially during winters to keep it naturally warm as much as possible. The orientation of the structure also maintains breezy natural ventilation even during summers. The water harvested or used is naturally treated through a worm-based Lombrifiltro system – think of it as biomimicry of our natural ecosystem. It provides enough for reuse (shower to WC), sanitation, drinking water, and sewage system. The wood used is treated with the best product on the market, certified without chemicals, and the best sealing technology in the world Rothoblass. The cabin completely eliminates the need for fossil fuels, external services, and bills!

ZeroCabin wants to change the habits of its occupants by providing the tools to live sustainably. “It is not about ‘what happens if the water-scarce,’ the questions these days should be ‘if the waters scarce, are my habits according to the water available in the place where I live? If the solar energy is not enough, are my consumption habits according to the energy available?” adds the team when talking about the thought process behind the design. All ZeroCabins regardless of the modality you buy (turnkey or DIY) have a structural base that allows optimal capture of their only two inputs, just like trees: sun and rainwater. The cabin maximizes functionality oversize but includes a wide range of modifications you can do based on the land you want to put it on and as long as it is aligned with their environmental guidelines.

Additionally, the company also encourages all cabin owners to be a part of their 100% ecological tourism network. Every cabin kit sold finances planting of native trees according to the reforestation campaigns. “We do not seek to make houses with character, spatiality, or identity … our architect is nature and its rules, and from there we create something for you. The result is a respectful mutualism that will not break the limits of the environment and in gratitude, you will be able to live without accounts happy of life for the rest of your life,” says the team with utmost love for their work and their efforts to help the environment. ZeroCabin is a home that adapts to you and the planet seamlessly.

This sustainable floating luxury hotel powered by clean energy has a revolving platform & is mobile!

Posted on by

This Eco-Floating Hotel in Qatar is raising the bar for eco-friendly travel and tourism! Powered by wind + solar energy it also features tidal sustainability mechanisms and a revolving restaurant to give you ALL the best views. Designed by Hayri Atak Architectural Design Studio (HAADS), the hotel would span over 35,000 sq m (376,000 sq ft) and house 152 rooms. The giant glass donut-shaped structure has a lush green cover integrated into its exterior and a mesmerizing indoor waterfall with a huge vortex-like glass roof.

Sustainability is at the core of this project and all of the design details are centered around it. The vortex shape of the roof will actually be used to collect rainwater for irrigation and more while solar panels + wind turbines will provide clean energy. Even the water current will be harnessed with a tidal energy system so when the hotel turns it can produce power similar to a dynamo. The hotel also intends to purify seawater and treat the wastewater it produces so it doesn’t harm the environment. Speaking of waste management, the team aims to develop waste separation units for efficiency and to use them as fertilizer in the landscape for the recycling of substances such as food waste.

With the aim to create maximum benefit towards maintaining ecological balance, the hotel will use a green energy production method called vawtau (vertical axis wind turbine and umbrella) which works as a wind turbine on the vertical axis and it has a function as a sun umbrella on the coastal band. Up to 25 kW of electrical energy can be obtained from each of the 55 vawtau modules which use wind flow caused by temperature difference in sea and land as its working principle. The greenery will help in regulating the temperature while also maintaining the flow of fresh air naturally.

The hotel will be located just off the shore and on a series of floating platforms and guests can access it via the 140-degree connecting pier, a boat, or a helicopter. The rotating platform will move very slowly – one revolution will take 24 hours – so guests won’t be dizzy and can enjoy the amenities like the spa, the pool, mini-golf, and the gym. The rotating movement is controlled by a dynamic positioning system that consists of a series of thrusters and propellers just like the ones that help ships stay on the right course. A luxurious 700 m2 lobby sits in the center featuring transparent vertical surfaces that let in natural light and give a light, airy, flowing visual effect. Each room comes with its own balcony and will offer different perspectives of the hotel and the views as it rotates slowly.

What makes it interesting is that although Eco-Floating Hotel is a project whose first leg is planned to take place in Qatar, the team is designing it in a way that it can be taken to different places with special mobile features. “Our team is working and studying with technical consultants and experts from different fields. This project adopts the motto of minimum energy loss and zero waste as a principle according to the design approach it has put forward. Due to its characteristic moving feature, it generates electrical energy by rotating around its position according to the water flow and provides users with different perspective experiences,” says HAADS.

It was inspired by the sea with which it is associated in every sense especially in its shape which was guided by whirlpools. Whirlpools form a rotation around themselves in a regular flow and that is reflected in the hotel’s shape which seems to have risen with its borders and evolved into a structure. The idea of the whirlpool also inspired the rotating platform and revolves around itself within the framework of controls in order to ensure electrical energy efficiency and everchanging panoramic views. Eco-Floating Hotel aims to minimize its intervention in the ecological balance by not using fossil fuels at any stage. These are all ambitious integrations and HAADS mentioned that feasibility and technical studies are currently ongoing to try and make this a reality by 2025.
