What Cabinet d'architectes p. HD does

Cabinet d'architectes p.HD is a Belgian architecture partnership founded in 1999 by Pascal Dumont and Gilles Hambucken, headquartered in the historic Hôtel de Warzée on Place Saint Jacques in Liège. The firm provides comprehensive architectural design services spanning new construction, heritage restoration, interior design, cultural facility design, and urban development. Its primary differentiator is specialized expertise in the restoration of classified Walloon heritage, including churches, collégiales, civic buildings, and aristocratic residences, balanced with capabilities in contemporary construction and adaptive reuse. The client base spans Walloon municipalities (Liège, Mons, Ciney, Namur, Huy), public institutions (CHU de Liège, FOREM), religious bodies, hospitality operators (Van der Valk), and private developers (Noshaq, Moury Promotion).

The practice operates across six interconnected service pillars: Architectural Design Services (full project delivery from concept to construction administration), Heritage Restoration (classified monuments and exceptional heritage sites), New Construction (residential, commercial, educational), Interior Design (retail, medical, restaurant, residential), Cultural Facility Design (museums, concert halls, theaters, including acoustic coordination with specialists such as Kahle Acoustics), and Urban Development (mixed-use blocks and public space). Anchor projects cited include the Grand Manège concert hall and conservatory in Namur (6,500 m²), the Hôtel de Ville de Mons (4,450 m²), the CHU de Liège pediatric unit (3,300 m²), the Palais des Congrès parking refurbishment (4,000 m²), and the REFLECTOR concert venue.

The business model is professional services: revenue derives from design fees, project management, and consulting on heritage and contemporary projects, awarded primarily through public procurement and direct commission. The firm is a privately held partnership with no external investors, marketing via its website portfolio (phd.archi) and organic social presence (Facebook, Instagram), and pursues clients through relationship-based business development anchored in its documented heritage restoration credentials. Geographic reach is concentrated in Wallonia, with active projects extending into 2026–2027.
