What Tate + Co does

Tate + Co is a London-headquartered, privately held architecture practice (formerly operating as Tate Harmer) founded in 2007 with a headcount in the 11–50 range. From its studio at 49–51 Central Street, London EC1V 8AB, the firm delivers architecture, masterplanning, and interior design services across the United Kingdom, with a stated focus on sustainable and regenerative design that connects people, places, and communities to nature. Its technical differentiation sits in three areas: Passivhaus and low-energy building design (documented on Kintyre, Chalkhurst Court, and the York St John Creative Centre, which achieved BREEAM Excellent); sensitive heritage and listed-building adaptation (Belsize Fire Station Grade II*, Warwick Castle in a Grade I Capability Brown landscape, Callow Hall Grade II*); and construction techniques that minimise impact on sensitive landscapes (helical pile foundations, modular prefabrication, no-dig servicing).

Tate + Co serves a vertical-segmented client base across five main areas: residential (sustainable and Passivhaus homes), hospitality and leisure (boutique hotels, treehouse developments, heritage hotel conversions), education (universities and schools), heritage and cultural (National Trust, museums, visitor centres), and land/property development (large-scale masterplanning). Named clients and project partners include York St John University, National Trust, The Eden Project, Watergate Bay Hotel, Wildhive Collection, Merlin Entertainments PLC, The Scout Association, St Paul's School, Yorkshire Water / Keyland Developments, Cranleigh Preparatory School, and The Brunel Museum. The firm has delivered more than 30 projects and earned multiple RIBA regional awards (2018, 2019), The Times Hotel of the Year (2021), and Boutique Hotelier Best Renovation (2021).

The business operates as a project-based professional services practice. Revenue is generated through quoted, scope-based professional fees for design and consultancy on construction projects; pricing is not publicly disclosed. Go-to-market is direct client engagement, supported by a portfolio website, a Knowledge Hub of educational content on sustainable design, social channels (LinkedIn, Pinterest, Vimeo), and an awards/competition strategy. The firm has been independently operated with no evidence of external investment or parent-company ownership, and its revenue is not publicly reported.
