What JPH Architects does

JPH Architects Ltd is a privately held, Passivhaus-certified architectural practice headquartered in Rhyl, North Wales, with additional offices in Chester and Wrexham. Founded in 2003 by John P Horden and Robert Blount, the firm provides design, planning, building regulations and full architectural services following the RIBA plan of works stages 0–6, serving residential homeowners, housing associations, local authorities, commercial clients and heritage/conservation clients across North Wales, Chester and the North West of England.

The practice's core technical differentiator is Passivhaus design executed via the German Passivhaus Planning Package (PHPP), supported by 3D modelling and walkthrough visualisation that lets clients preview buildings pre-construction. It is complemented by conservation and heritage consultancy skills covering listed buildings and conservation areas. The firm holds ISO 9001:2015 certification, UK and EU GDPR compliance, and an in-house Certified Passive House Designer credential, and reports quantifiable Passivhaus outcomes of up to 90% lower energy consumption versus conventional buildings and 86% lower lifetime emissions than an equivalent gas-boiler-compliant new build (2022 reference). Named project credentials include Passivhaus apartments for Denbighshire County Council and the GlasDir development for housing association ClwydAlyn with Williams Homes Bala as contractor.

Revenue is generated through project-based professional services fees covering architectural drawings, planning applications, building regulations submissions, construction detailing, specification, and project oversight. Customer acquisition is sales-led, relying on direct office consultations and site visits across three regional offices, supplemented by inside sales via phone, email and website contact forms, organic social (Facebook, X, Instagram), case-study blog content, and community workshops held at the Chester crypt venue. Ownership remains founder-led and internally developed, with Robert Blount as senior director following John Horden's retirement, and William (a chartered Architectural Technologist trained at JPH) added as director in 2019; no external institutional investment, parent company, or M&A activity is disclosed.
