What LSI Architects does
LSI Architects (Design) Ltd is a privately held UK architectural practice headquartered in Norwich with a regional studio in London. The firm delivers RIBA Chartered architectural services across six verticals — healthcare, education, residential, workplace, sports & recreation, and community & leisure — with healthcare and education as the dominant revenue drivers, evidenced by a portfolio spanning from £10K refurbishments to £100M+ acute hospital schemes, and award-winning projects including the £10.6M Arthur Rank Hospice, £12.5M Priscilla Bacon Lodge, and £65M UEA Sky House.
The practice operates on a project-based professional services model, generating fees through competitive tendering, public sector framework agreements (notably the December 2025 appointment to the NHS Property Services Architects Framework across all four UK lots), and direct client appointments. Its core technology stack is BIM-centric, using ArchiCAD and Solibri in a 3D collaborative design environment that has produced coordinated "C-sheets" featured in national guidance. The firm is differentiated by deep healthcare domain expertise dating to the 1980s, palliative and dementia care specializations, CIAT Registered Principal Designer capability for Higher Risk Buildings, and an extensive accreditation stack (RIBA Chartered, CIAT Registered, BCorp, ISO 9001/14001, Investors in People Gold, Mind Workplace Wellbeing Index Gold).
Commercially, LSI pursues a sales-led GTM focused on UK public sector and institutional clients (NHS trusts, county councils, universities, independent schools, hospices) and selected private developers. The firm operates without external investment, is founder/management-owned, and reinvests organically through project revenues, supported by a "grow our own" apprenticeship pipeline that has produced multiple internal promotions to Associate and Director level.
