HAC GROUP

What HAC GROUP does

HAC Group (legally HAC Designs Ltd.) is a UK-based, privately held architectural design and design-build firm headquartered in Reading (Hurst), with additional offices in Portsmouth and Richmond (London). The company delivers an end-to-end service for residential property transformation through five integrated divisions: HAC Designs (architectural design), HAC Structure (structural engineering), HAC Build (construction), HAC Interiors (interior styling), and HAC Landscape (landscaping). Service offerings span home extensions (single and two-storey), loft and garage conversions, flat conversions, new dwellings, renovations, and period property modernisations, supported by in-house fully rendered 3D visualisation models used for client-facing design previews.

The business operates with a small team of 1-10 staff led by Owner and Managing Director Hayden Cooper, with capability covering architectural design, structural engineering (claimed two-week typical turnaround), planning application submission and management, building regulations compliance, construction execution, interior design, and landscaping. The company positions itself as a single point of contact eliminating the need to coordinate multiple architects, engineers, and builders. Underlying technology centres on 3D modelling and standard architectural design tooling; no proprietary AI/ML capability, software platform, or API is disclosed.

Revenue is generated through project-based professional services fees tied to development budget and scope, with disclosed client project budgets ranging from £0 up to £950k+. Pricing is quote-based and not publicly disclosed. Customer acquisition relies on a free 30-minute consultation (a £120 + VAT fee applies beyond 30 miles of Reading HQ), digital presence on Houzz and Google Reviews, organic social referrals in local Facebook groups, an educational blog targeting home improvement search intent, and referral partnerships with local surveyors via Local Surveyors Direct. The primary customer segment is residential homeowners undertaking extensions or conversions, with secondary segments addressing property developers/landlords and period property owners; all publicly cited customers are residential SMBs or individuals. Ownership is founder-controlled with no external institutional investors evidenced.

Broad incumbents

• Allies and Morrison: Allies and Morrison is one of the UK's largest and most established architectural practices, working across residential, commercial, education, and masterplanning sectors. Comparable to HAC Group on residential architectural services, but operates at significantly larger scale and broader portfolio.
• EPR Architects: EPR Architects is a large UK architectural practice with significant residential, hospitality, and mixed-use work. Overlaps with HAC Group on architectural design and structural problem-solving for residential clients, but at a much larger, multi-sector scale.
• Foster + Partners: Foster + Partners is a globally recognised architectural firm with a small residential studio alongside its commercial, infrastructure, and cultural portfolio. Touches HAC Group's residential architecture space but operates at a vastly different scale and brand.

Direct peers

• Resi: Resi is a UK-based residential architectural practice focused on extensions, loft conversions, and home renovations using a tech-enabled, fixed-fee pricing model. Highly comparable to HAC Group in target customer (UK homeowners), service mix (architectural design + project management), and project budget range.
• Stirling Ackroyd: Stirling Ackroyd is a London-based chartered architectural and surveying firm with a strong residential focus on extensions, conversions, and refurbishments. Comparable to HAC Group in residential architectural services, multi-office UK footprint, and homeowner client base.
• Mae Architects: Mae Architects is a London-based practice focused on high-quality residential and small-scale community projects, including extensions, refurbishments, and new-build homes. Directly comparable to HAC Group on residential design quality, owner-engaged delivery, and project typology.
• TaylorHind: TaylorHind is a UK architectural and design practice with residential design and build capability, serving homeowners on extensions, renovations, and bespoke homes. Closely comparable to HAC Group in integrated design-and-build offering and residential homeowner focus.

Others

• Houzz: Houzz is the leading marketplace and portfolio platform for residential design professionals, and is one of HAC Group's primary customer-acquisition channels. Adjacent ecosystem enabler rather than a competitor, but materially shapes how HAC and similar UK residential architects reach customers.
• RIBA (Royal Institute of British Architects): RIBA is the UK's chartered professional body for architects, governing accreditation, codes of conduct, and standards that frame how firms like HAC Group position themselves as qualified architectural practices. Adjacent, not competitive.
• NHBC: NHBC is the UK's leading new-home warranty and standards body, interfacing with architects, builders, and developers across residential construction. Not a direct competitor, but adjacent ecosystem participant relevant to HAC Build's building-regulations and warranty positioning.
