What 5th Studio does

5th Studio Ltd. is a UK-based architecture and urban design practice founded in 2003, operating dual studios in London (headquarters, Unit 14, 21 Wren Street, WC1X 0HF) and Cambridge (Darkroom, Gwydir Street, CB1 2LJ). The firm delivers an integrated suite of seven professional services: Architecture/Buildings, Urban Design/Masterplanning, Retrofit/Adaptive Reuse, Sustainability/The Environment, Movement/Transport, Planning/Policy Development, and Advocacy/Project Shaping. Director Tom Holbrook leads a multi-disciplinary team engaged across a spectrum from individual buildings to city-wide strategies, including major regeneration programmes such as Old Oak and Park Royal (described as one of Europe's largest regeneration projects), Stratford Station Vision, the Royal Docks Corridor, East Norwich, and the Global Centre of Rail Excellence in Wales.

The firm operates as a bespoke professional services practice, generating revenue through project-based commissions secured via competitive tender, government framework appointments, and direct client engagement. Distribution is anchored by access to institutional frameworks, most notably the Greater London Authority's ADUP II Framework and the Mayor of London's Architecture + Urbanism Framework, alongside direct appointments from local authorities (Westminster City Council, London Borough of Lewisham), development corporations (Old Oak & Park Royal Development Corporation, London Legacy Development Corporation, LCR), national government bodies (Transport for London, National Infrastructure Commission, Greater London Authority), universities (Trinity College, Churchill College, Darwin College Cambridge; Oriel College Oxford), and selective private sector clients (British Land, Dorrington). Pricing is not publicly disclosed; engagements are bespoke to client and project requirements, and no subscription, transactional, or productised revenue streams are evident.

The practice has built measurable recognition through documented outcomes, including an 80% energy demand reduction and 88% carbon emissions reduction at Trinity College's New Court retrofit, 15–40% energy use reductions at Churchill College's Wolfson Flats, and 40% of hot water supplied by solar at the same project. Awards include Guardian #1 (2022), multiple New London Architecture Awards (2019, 2021, undated), the inaugural Architecture Today Editor's Award (2023), and Certified B Corporation status (April 2024). The firm is presently engaged on significant regeneration schemes and is actively recruiting a Studio Manager and Part 2 Urban Designers as of mid-2025. No AI/ML, software, or digital product layer is evident in the source material; the firm's technology is professional design expertise delivered through human practitioners.
