What TTSP does
TTSP is a privately held architectural and design practice headquartered at The Loom in Aldgate, London, founded in 1961 by Thomas Saunders as a sole trader in Essex and now operating as a multi-generational partnership with an established ESOP ownership structure. The firm operates three core service lines — Architecture, Design (interior fit-outs and workplace planning), and Technology/Mission Critical (specialist data centre design) — and serves enterprise clients primarily across two verticals: data centre/mission critical facilities and commercial/corporate office, with a smaller public sector practice covering government, education, healthcare, and police estates.
The firm's underlying capability base is built on 25+ years of accumulated specialist data centre domain expertise, covering hyperscale, colocation, and modular typologies, alongside sustainable design methodology including BREEAM Excellent targets, low-carbon materials, heat reclaim systems, and district-heating export provisions. Notable project work spans the £3.75bn South Mimms DC01 campus (with DC01UK), the 210MW Olympus London Docklands campus (with Ada Infrastructure), the £750m Bidder Street hyperscale data centre (with Foster + Partners, Legal & General, and Goldacre), and the £250m Salford data centre (with Keysource), alongside award-winning commercial work for Aviva, Nomura, Goldman Sachs, Jaguar Land Rover, and Cancer Research UK.
TTSP earns revenue through professional services fees negotiated on a project-by-project basis, with multi-year contract cadences aligned to the design, planning, and construction phases of each commission. The firm goes to market via enterprise field sales, competitive tendering, and repeat-client relationships, supported by an active presence at BCO, DataCloud Global Congress, MIPIM, Data Centre World, UKREiiF, and CoreNet Global Summit. The customer base is broad by logo but skewed toward a small number of large hyperscale data centre projects at any given time, given the firm's 11-50 employee scale.
