What Transition by Design does
Transition by Design is an Oxford-based worker cooperative and community interest company (CIC) founded in 2011 that delivers architecture, deep ecological retrofit, community engagement, and participatory urban design services. Its core technical offerings centre on Passivhaus and EnerPHit Plus certified sustainable design, including the second EnerPHit Plus certified retrofit in the UK at Hutchcomb Road, which achieved a 120% energy use reduction and carbon-positive status. The practice combines technical retrofit expertise with a participatory design methodology (the CIA model: Consult, Inform, Activate) and has built a portfolio of community-led housing, homelessness accommodation, meanwhile use, and urban regeneration projects for local government and community sector clients.
The company generates revenue through project-based professional services fees across architecture, retrofit, community engagement consultancy, urban design, and funded research. Its customers are predominantly local authorities (notably Oxford City Council), community land trusts (Oxfordshire Community Land Trust, Thame CLT), housing associations (Platform Housing Group), community interest companies (Makespace Oxford CIC), and individual homeowners seeking Passivhaus-grade retrofits. Distribution is direct, region-focused (Oxfordshire, Cambridge, Thame), and reinforced through thought leadership: blog articles, monthly newsletters, podcast appearances, award submissions, and research publications supported by funders including the Lankelly Chase Foundation. The cooperative also spun out Makespace Oxford CIC in 2018 and has developed an extensive partner ecosystem spanning Bioregional, Gort Scott, Design Council, AMC Build Ltd, Eco Design Consultants, and a network of community organisations.
The business is small (1-10, mostly part-time members across three cities), democratically governed as a worker cooperative with no external shareholders, and credentialed as a RIBA Chartered Practice, Co-ops UK member, Workers' Cooperative member, and Oxford Living Wage employer. Visible strategic activity through 2025-2026 includes expansion into Cambridge retrofits, the OX4 Community Retrofit project, ongoing Cowley Branch Line and Blackbird Leys Community Centre commissions, and continued Pipeline project development, supported by a small 2021 grant from the Housing Advisors Program.
