ECOLIV is a retrofit conversion project in the United Kingdom, creating a sustainable building optimized to reduce its carbon footprint and carbon emissions. The two-storey building consists of seven bedrooms, seven bathrooms and a living space. The property features water-saving solutions such as a greywater collection and treatment system. It also features a green wall in the living area, bringing the atmosphere and sensation of nature to the interior of the building. The spaces were also designed to be easily adaptable; for example, some bedrooms are multi-purpose and can also be used as yoga or meditation rooms.
