What Llewelyn Davies does

Llewelyn Davies is a London-headquartered architectural practice founded in 1960, operating as Llewelyn Davies Weeks Limited and part of The Covalent Group Limited. The firm employs approximately 240 staff across multidisciplinary teams and specializes in three core sectors: healthcare buildings, master planning, and aviation. It has delivered more than 250 hospitals across over 80 countries, anchored by long-tenure relationships with UK NHS trusts, the Government of Jersey, the Stavros Niarchos Foundation, and international airport authorities including Cathay Pacific.

The practice's core output is architectural design services delivered by teams of architects, planners, engineers, and specialists working across multi-year design and construction phases. Its current project portfolio includes the £710 million Overdale Acute Hospital in Jersey, the £140 million Broomfield Hospital redevelopment in Chelmsford, and the £90 million Great Ormond Street Hospital Morgan Stanley facility in London. Aviation work spans terminals and facilities for airport authorities in Algeria and China alongside Cathay Pacific commissions.

Llewelyn Davies operates as an employee-owned private limited company, generating revenue through professional fee streams tied to construction capital values. Its business model depends on securing work via competitive frameworks, NHS procurement frameworks, direct government commissions, and developer-led tenders in its three specialty verticals, with regional offices supporting international project delivery.
