What xsite architecture does

xsite architecture is a private architectural practice headquartered in Newcastle upon Tyne, United Kingdom, providing professional design services across multiple building sectors. The firm's service portfolio spans workplace and commercial architecture, private residential and domestic projects, heritage and conservation work on Grade I and Grade II listed structures, specialized church quinquennial inspections and re-ordering, hospitality venue design (breweries, bars, restaurants, spas), and cultural and civic projects including public art trails and visitor facilities.

The firm was formed through the 2021 merger of xsite architecture with spence and dower, which added accredited heritage and conservation expertise to the existing workspace, residential, and civic capabilities. Notable projects in the portfolio include the Boiler Shop and Pattern Shop at Stephenson Quarter, the Belsay Awakes & Regeneration scheme (winner of the Constructing Excellence North East Conservation & Regeneration Award 2024), conservation of the historic Union Chain Bridge, the Ouseburn Quays community hub (51 apartments), and the Nile + Villiers scheme in Sunderland (75 dwellings plus commercial units, planning approved July 2024). The practice also delivers ecclesiastical work including quinquennial inspections for listed churches.

The business operates on a project-based professional services revenue model, engaging clients directly for quote-based engagements varying by project scope and complexity. The go-to-market is sales-led and relationship-driven, with primary geographic focus on North East England. Distribution occurs through direct client engagement via phone, email, and office visits, supported by organic Instagram marketing showcasing completed projects and award achievements, and participation in industry events such as RIBA Open Studios. The firm has 11-50 employees, no disclosed funding, no parent company, and no institutional investment indicated in the available data.
