What Lomas and Mitchell Architects does

Lomas and Mitchell Architects Ltd. is a private, RIBA Chartered architectural practice founded in 1997 and headquartered at the MSE Building, Markham Vale, Chesterfield, United Kingdom, with a headcount of 1–10. The firm delivers professional architectural services across residential and commercial sectors, with documented projects spanning Derbyshire, South Yorkshire, West Yorkshire, and Shropshire. Core service lines include residential new builds, internal remodelling, home extensions, deep retrofits, commercial offices, and public-sector buildings.

The practice's core differentiator is specialised expertise in low-energy, sustainable, and Passivhaus-standard construction, including triple-glazed windows, high insulation, airtight envelopes, mechanical ventilation with heat recovery, and renewable energy integration. It holds niche capability in Paragraph 84 (formerly Paragraphs 81, 80, 79, 55) planning policy projects — isolated countryside dwellings requiring exceptional design quality — evidenced by The Long House project (Grand Designs, September 2022) and other residential case studies such as The Fishery, The Link Barn, and Blackwood House. The practice is a member of RIBA, ARB, AECB, the Green Register, and is a LABC Regional Winner.

Commercially, Lomas and Mitchell operates a sales-led professional services model, engaging clients through direct phone and email contact, with a free initial consultation leading to fee-based full architectural services (concept to completion) and watching brief roles during construction. The principal is Richard Lomas. Customers are principally residential homeowners (mid-market) and a smaller mix of commercial and public-sector clients including MSE, Turning Point, and Rotherham Interchange. No pricing, revenue, or financial figures are publicly disclosed.
