T2 architects

What T2 architects does

T2 architects is a Winchester-based, design-led architectural practice founded in 2007 by Jeremy Tyrrell and operating as a private limited company with 1-10 employees. The firm delivers architectural design, planning consultancy, and Passivhaus/sustainability advisory services, structured around the RIBA Plan of Work stages, for residential, commercial retrofit, and student accommodation projects across the South of England with selective work in Cardiff and Exeter. Its client base spans Local Authorities (notably Winchester City Council), regional developers and house builders (Drew Smith, Doswell, Hazeley, Element Homes, Millgate, Candover Green), student accommodation operators (The Neighbourhood, Cavendish Winchester), and individual homeowners.

The practice's commercial model is project-based professional services revenue, earning architectural and consultancy fees typically representing 7-12% of construction cost on projects valued at £3m-£9.5m. Its technical differentiation centers on Passivhaus-aligned design, supported by memberships in the Passivhaus Trust, AECB, and Good Homes Alliance, alongside BREEAM-informed sustainability work and RIBA Chartered Practice status. Notable credentials include City of Winchester Trust Design Awards (2015), Solent Design Awards (2016), and Jeremy Tyrrell's tenure as RIBA Hampshire Chair (2019-2021).

Capability delivery relies on standard architectural tools, with PHPP used for energy modeling; the firm does not disclose proprietary technology or AI/ML systems. Leadership comprises co-directors Jeremy Tyrrell and Catherine Tyrrell, supported by a small team that has seen incremental additions (Thomas Thwaites 2020, Ben Sunley 2024), with the founder's specialist low-energy expertise serving as the core intellectual asset.
