HLM Architects

What HLM Architects does

HLM Architects is a UK and Ireland architecture, landscape, and interior design practice with over 60 years of operating history, delivering comprehensive design services from concept through construction completion. The firm operates eight regional studios (London, Sheffield, Plymouth, Cardiff, Glasgow, Belfast, Dublin, and Birmingham opening in 2026) and serves public sector clients across education, healthcare, defence, justice, residential, and commercial sectors, with a particularly strong footprint in higher education (University of Glasgow, University of Leeds, King's College London, University of Sheffield, University of St Andrews, University of Strathclyde) and NHS/local authority commissions. Headcount is reported in the 251–500 range, and the practice is structured as a private limited company (HLMAD Limited) wholly owned by the Covalent Group Limited, having transitioned to a 100% Employee Ownership Trust in 2020.

The firm's core offerings span architecture, landscape architecture, interior design, conservation, masterplanning, sustainability consulting, social value assessment, and industrialised construction / Modern Methods of Construction (MMC). Proprietary technology includes HLM Place, a place-based data dashboard integrating land and building asset data for public sector clients; HLM Insight and HLM Healthcheck, digital engagement and operational compliance tools used primarily in healthcare and research projects; and a Digital Kit of Parts framework for MMC housing commissioned by the Ministry of Housing, Communities and Local Government. The practice holds BREEAM Outstanding and Excellent certifications across multiple flagship projects and meets RIBA 2030 and LETI net zero operational energy targets.

HLM generates revenue through project-based professional services fees, securing work primarily via competitive tendering and public sector framework agreements. Distribution is direct-to-client, leveraging regional studios to maintain local relationships with local authorities, NHS trusts, universities, and government bodies; named project values range from £19.4M to £90M. Since 2020, ownership has been held in trust for employees, with no external institutional investors, and the firm has grown organically through studio expansion (Dublin 2024, Plymouth 2025, Birmingham 2026) and recognised industry positioning, including Architectural Practice of the Year awards in 2023 and 2026.

Scale indicators10 records

Recent moves9 records

Expansion highlights6 records

Broad incumbents

• AtkinsRéalis (formerly Atkins): Global design, engineering and project management consultancy with a large UK architecture practice that competes head-to-head with HLM on higher education, healthcare and defence frameworks. Operates as part of a much larger global group, giving it deeper bench and broader geographic reach on mega-projects.
• Foster + Partners: Global architecture practice with a UK public sector practice that competes on flagship university and healthcare projects. Much larger and more internationally focused, but a benchmark competitor on the marquee education and research projects where HLM competes.

Direct peers

• BDP (Building Design Partnership): Major UK-based interdisciplinary architecture practice with overlapping specialisms in healthcare, education and masterplanning. Closely comparable in scale, sector mix (education/healthcare heavy), and UK/Ireland studio footprint, making it one of HLM's most direct competitors on NHS and university frameworks.
• Feilden Clegg Bradley Studios (FCBStudios): UK architecture practice with comparable scale and strong specialisation in education, healthcare and research facilities, with award-winning sustainability credentials (BREEAM, Passivhaus). Directly competes with HLM on university and public sector work and shares a similar design-led, values-driven positioning.
• AHR (formerly Aedas UK): UK-headquartered architecture and building consultancy with overlapping education, healthcare and workplace sectors. Comparable size and studio model, and a frequent co-bidder on UK regional public sector frameworks that HLM targets.
• Allies and Morrison: Established UK architecture practice covering education, housing, regeneration and public sector work. Similar studio model and cultural positioning to HLM, with comparable award recognition and a comparable UK-wide project footprint.
• Haworth Tompkins: UK architecture practice with strong education, cultural and theatre sector credentials, competing on similar public and third-sector frameworks. Smaller than HLM but operates with a comparable design-led, employee-centric culture.
• Penoyre & Prasad: UK architecture practice focused on housing, education and healthcare, with sustainability credentials comparable to HLM. Similar mid-size profile and overlapping client base in higher education and public sector housing.
• Purcell Architecture: UK architecture practice with strong heritage/conservation and education sector expertise, similar in scale and culture. Overlaps with HLM on conservation, masterplanning and university estate work and competes on similar UK public sector frameworks.
• Scott Brownrigg: UK-headquartered architecture and interior design practice with overlapping sectors in education, workplace and residential. Comparable scale and studio model, frequently bidding against HLM on UK public sector and developer-led work.
