What if a luxury home could be built from material that would otherwise have gone to landfill? In Riebeek-Kasteel, a small town in South Africa’s Western Cape, Louis Jansen van Vuuren and Hardy Olivier have turned that idea into their home, EcoSpace. According to Zerocrete, the 305-square-metre, double-storey residence is the world’s first luxury home built entirely with its Zerocrete material, which incorporates reclaimed plastic, fabric and glass waste. Zerocrete says construction diverted nearly 97 tonnes of non-recyclable waste from landfill, including 55,636 kilograms of reclaimed plastic, 26,115 kilograms of fabric and textiles, and 15,281 kilograms of glass. The company says the plastic is equivalent to nearly 4 million PET water bottles and forms the core of the home’s walls and furniture. The project was developed as a proof of concept to show how waste-derived materials could be incorporated into a high-end residential building without abandoning conventional ideas of comfort or design.

Fabric and glass round out the home’s unusual material mix

Plastic is only part of the material story. Zerocrete says EcoSpace incorporates 26,115 kilograms of discarded fabric and textiles, a quantity it equates to more than 186,000 T-shirts, into building materials valued for their insulation properties. Another 15,281 kilograms of reclaimed glass, which the company compares with more than 38,000 wine bottles, were incorporated into countertops and other surfaces. Zerocrete also says that 50% of the cement required for the project was replaced with a low-carbon alternative, which the company estimates prevented 283,000 kilograms of carbon dioxide emissions. That figure is a company-reported estimate rather than an independently verified measurement. Zerocrete says the project also created 36 new jobs and provided local artisans with training in working with the new material. The company’s description of the house emphasises that the recycled content was not intended to remain hidden: coloured glass is visible in countertops, fibres contribute texture to walls and polished plastic gives some floors a terrazzo-like appearance.

The couple brought decades of experience to the project

EcoSpace is not the couple’s first experience creating distinctive homes. In an article published by Your Luxury Africa titled “EcoSpace: An Extraordinary Home Built from Waste”, Jansen van Vuuren and Olivier said they had owned five homes in France over 27 years, ranging from a small house in Lapeyrouse to a château in the French countryside. They eventually returned to South Africa and chose Riebeek-Kasteel for their new home. The couple said they were drawn to the town’s location at the foot of the Kasteelberg, with a valley surrounded by vineyards and olive groves and views towards the Groot Winterberge mountains. They also described the town as having two distinct rhythms, becoming lively with visitors during weekends and holidays before returning to the quieter atmosphere of a rural village during the week. Their experience with historic and artistic properties also influenced the way EcoSpace was conceived, with the finished home combining the industrial appearance of Zerocrete surfaces with antique French pieces, contemporary furniture, art and Aubusson tapestries.

The home’s plastic came from a major South African retailer

Structural engineer Johan Coetzee and his company were responsible for taking the project from concept through construction. In an article published by the Sunday Times titled “Stylish home of the future built from waste”, Coetzee said approximately 55 tonnes of non-recyclable plastic used in the building came from South African retailer Shoprite. The newspaper reported that the material was equivalent to about 3.9 million plastic bottles, broadly consistent with Zerocrete’s more precise figure of 55,636 kilograms and its estimate of nearly 4 million PET bottles. Coetzee described the project as a prototype intended to demonstrate what could be achieved using waste-derived construction materials and said the construction cost remained aligned with standard market rates for a comparable home. The Sunday Times also reported Coetzee’s estimate that the completed building produced less than 200 kilograms of carbon dioxide emissions per square metre, compared with an estimated 850 kilograms per square metre for conventional construction in South Africa. Those figures are Coetzee’s stated estimates and should not be treated as an independently verified life-cycle assessment.

The finished home keeps the focus on comfort and design

Although developed as a proof of concept, EcoSpace was designed as a complete residential property, with bedrooms, bathrooms, living spaces, a studio and a garage. Zerocrete describes the 305-square-metre house as a double-storey property with a large open-plan ground floor connecting the lounge, dining and entertainment areas. The home has two en-suite bedrooms, including a main suite with a full bathroom containing both a bath and shower, while the guest bedroom has its own shower room. Upstairs, an office or studio has a further en-suite bathroom, bringing the total to 3.5 bathrooms, alongside a spacious garage. The material itself remains visible throughout the interiors, with coloured glass embedded in countertops, fibres adding texture to walls and polished plastics creating depth in the floors. Rather than attempting to disguise the origin of the materials, the design makes that history part of the aesthetic. The result is a house intended to demonstrate Zerocrete’s central proposition: that industrial waste can be transformed into structural and decorative materials for a contemporary home without making sustainability the only defining feature of the finished space.
