What Child Graddon Lewis does

Child Graddon Lewis (CGL) is a privately held architectural practice founded in London in 1992, specializing in urban regeneration, affordable housing, mixed-use development, retrofit and reuse, and public realm design. The firm is a RIBA Chartered Practice (No. 1949312P) and holds Cyber Essentials certification, delivering services to UK local authorities (Westminster City Council, Hackney Council, Tower Hamlets), housing associations (Notting Hill Housing, Southern Housing, A2Dominion, Westminster Community Homes), and private developers (Willmott Dixon, Countryside Properties, Allied London). Notable project outputs include Westmead (65 affordable homes, AECB CarbonLite certified), Dudley House (197 affordable homes in Westminster), Tower Court (132 council homes in Hackney, winner of multiple 2025 awards), 300 Harrow Road, Leeds Dock, and Victoria Wharf.

The practice operates on a professional services business model, generating revenue through fee-based project commissions structured along RIBA architectural fee scales. Engagement is project-based, sourced via competitive tenders for public sector work, direct appointments from repeat public and private sector clients, and ongoing developer partnerships (e.g., Adam Khan Architects and Muf Architecture/art on Tower Court). Pricing is project-specific based on scope and complexity rather than standardized SaaS tiers, and contract durations span multi-year design and delivery engagements. Geographic footprint covers London (headquarters at 28A Easton Street) and a Leeds office opened around 2015 to support northern England projects.

The firm's underlying technology stack comprises industry-standard BIM and design software (AutoCAD, Revit) combined with a sustainability-focused design methodology informed by AECB CarbonLite and Passivhaus principles. Differentiating design concepts include the Velo Village concept (integrating secure bicycle storage into housing) and a social-value-led regeneration approach that prioritizes community benefit beyond site boundaries. Distribution is direct enterprise field sales through public sector procurement frameworks and developer partnerships; marketing relies on industry awards, social media presence (LinkedIn, Twitter, Instagram), and community engagement programmes including Build The Way.
