A-Zero Architects is a RIBA chartered practice based in London.

Since 2010, the studio’s work has focused on designing and procuring buildings in a way that doesn’t harm the environment. Working predominantly in the residential sector, the practice enjoys working at a variety of scales from residential retrofits to new build houses, to mixed use developments. They strive to create joyful spaces using a palette of natural materials, whilst targeting low energy performance, including the Passivhaus standard.

A-Zero works collaboratively with clients through all stages of a project, from feasibility, planning, detailed design, and tendering to contract administration during construction, and aim to embed environmental considerations through all of these stages, combining functional, cost-effective architecture with a sense of specificity to the client and the place.

Do+Co Studio is a Passivhaus-certified architecture studio based in Dulwich, South London. They are open-minded, open-hearted, and devoted to creating work that fosters happy lives and a promising future. Established in 2013 as Darren Oldfield Architects, they collaborate with homeowners, developers, and small businesses to create carefully crafted, sustainable buildings. Director Darren has been working with Passivhaus principles since 2008, when he contributed to the first certified Passivhaus non-domestic retrofit in the UK.

Do+Co Studio co-creates beautiful and intriguing buildings and spaces. They work with clients to design places full of personality that tell a story, induce joy, and lift spirits. Regardless of the project’s scale, their starting point is always light, volume, and space – a trinity of principles that leads to original responses centred on well-being and quality of life.

The studio prides itself on being unpretentious, natural collaborators who understand that the best ideas are those that improve life for everyone. This collaborative spirit extends to working closely with clients, consultants, and communities, resulting in the right solutions and building long-lasting relationships and friendships.
