What BDC does

Building Design Consultants Limited (BDC) is a privately-held UK civil and structural engineering consultancy headquartered in London with a regional office in Billericay, Essex. The firm provides detailed civil and structural design services across eight sectors: residential, education, healthcare, retail and commercial developments, retirement living, community buildings, refurbishment, and infrastructure. Its technical work covers reinforced concrete frames, load-bearing masonry, foundations, and complex structural solutions for challenging site conditions, including proximity to railways, waterways, contaminated land, and difficult ground conditions. BDC deploys standard industry engineering tools — SCIA Engineer for 3D modelling, CADS Footfall Analysis, and Finite Element Modeling — and holds ISO 9001 (quality management) and ISO 14001 (environmental management) certifications.

BDC operates a project-based professional services model, earning fees through direct commissions from developers, housing associations, NHS trusts, local authorities, and other clients, alongside appointment on multiple UK-wide framework agreements. The firm serves a predominantly enterprise and public sector client base, with named customers including Crest Nicholson, Countryside Partnerships, L&Q, McCarthy Stone, A2 Dominion, The Hyde Group, the NHS, and Thurrock Council. Notable ongoing engagements include Rochester Riverside (£419m GDV, 1,400 homes), The Quarry in Erith (870 homes), Acton Gardens, and Clay Farm in Cambridge, several of which have won industry recognition including a 2021 LABC Award and First Time Buyer Awards in 2019 and 2022.

The firm employs 39 people and is privately owned with no disclosed parent company, external investors, or institutional shareholders. Its stated strategy is to build on a stable team that has worked together for over 20 years, extending delivery across London, the Home Counties, and nationwide UK through commissions and frameworks, with the website tracking a '% Repeat Work / Client Referrals' metric as a primary commercial KPI.
