What D5 Architects does

D5 Architects LLP is a private, Birmingham-headquartered architectural design practice operating as a limited liability partnership registered in England and Wales (company number OC312539). The firm delivers comprehensive architectural services across RIBA Work Stages 1-7, covering concept design, planning applications, technical design, contract administration and compliance monitoring. Its core technology stack is industry-standard, comprising Revit and AutoCAD used to deliver projects across multiple sectors: Transportation (rail stations, bus stations, airport terminals, ferry terminals), Education (universities, schools, nurseries, colleges), Residential (new build, conversion, restoration, including heritage work in Birmingham's Jewellery Quarter Conservation Area), Community and Faith facilities, Workplace/Commercial, and Sport & Leisure.

The practice is project-based and generates revenue through professional services fees, sourced via competitive tendering, framework agreements and repeat client commissions. Its named client base skews to enterprise and government: Birmingham Airport (25+ year continuous relationship), Network Rail, West Midlands Combined Authority, Government Property Agency, Coventry University, and developers including Elevate Property Group and Complex Development Projects. Pricing is quote-based by project scope, complexity and sector, and is not publicly disclosed.

D5 positions itself on a design-led, client-focused approach with multi-sector breadth, recognized through regional industry awards (Scottish Property Awards 2016, Insider Property Awards 2014, Galvanizer Awards 2013, RIBA West Midlands Housing Design Competition 2026). The firm operates with 11-50 staff from its Birmingham office, pursues public sector frameworks, and participates in industry events such as UKREiiF. No external funding, parent company, AI/ML capabilities, or proprietary platform technology are evident; differentiation rests on people, heritage domain expertise, and accumulated brand credibility in the Midlands property and transport infrastructure markets.

Scale indicators1 record

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• AHR (formerly Aedas UK): Large UK-headquartered architecture and building consultancy with deep transportation, education, and public-sector portfolios. Direct comparator for D5's transportation and education engagements at greater scale, often competing on the same tender frameworks (e.g., Network Rail, DfE).
• BDP (Building Design Partnership): Major international architecture and engineering practice with extensive UK transportation, education, and healthcare portfolios. Competes with D5 for larger public-sector commissions while also operating as a tier above on mega-projects.
• Allies and Morrison: Established UK architectural practice with award-winning residential, heritage, and public-sector work. Comparable to D5 on heritage/conservation and design quality, though operating at meaningfully larger scale on masterplans.

Direct peers

• MJP Architects: UK mid-sized architectural practice focused on transportation infrastructure, particularly rail and station design. Closest direct competitor to D5's transportation segment, sharing project types (rail station redevelopments, Access for All schemes) and public-sector client base.
• Stride Treglown: UK-wide architectural practice with significant transportation, education, residential, and heritage portfolios. Directly comparable to D5 in sector mix and project scale, and a frequent co-bidder on UK regional public-sector frameworks.
• Pick Everard: Mid-sized UK architectural and engineering consultancy with strong public-sector, education, and heritage portfolios. Comparable to D5 in regional UK focus, multi-sector coverage, and competitive positioning on framework agreements.
• Glancy Nicholls Architects: Birmingham-based architectural practice with strong transportation, residential, and heritage credentials. Highly comparable given shared West Midlands focus, similar sector mix, and comparable size bracket.
• Feilden+Mawson: UK mid-sized architectural practice with strong heritage, education, and transportation portfolios. Comparable to D5 in size bracket, sector mix, and approach to heritage-led public-sector commissions.

Regional players

• Sjölander da Cruz Architects: London-based architectural practice with strong heritage/conservation and community-sector portfolio. Comparable to D5 on conservation design quality and community-facility project types, though geographically focused on London rather than the West Midlands.

Others

• Mott MacDonald: Global engineering, management, and development consultancy. Listed as a D5 delivery partner on the Camp Hill Line stations project — relevant as a frequently co-bidder and engineering complement rather than a direct architectural competitor.
