TPAHG architecten

What TPAHG architecten does

TPAHG architecten BV is a private Dutch architecture firm headquartered in a restored former prison complex on the Oostereiland in Hoorn, the Netherlands, specializing in heritage restoration, monument preservation, sustainable renovation, and adaptive reuse. The firm serves housing corporations, municipalities, museums and cultural institutions, and private individuals across the Netherlands and Belgium, with a disclosed project portfolio that includes nationally significant sites such as Muiderslot, Slot Loevestein, Teylers Museum, the Rijksmuseum offices, and the Missiehuis in Hoorn (winner of the 2024 Pieter van Vollenhovenprijs).

The service offering is organized around four core categories—Restauratie (restoration), Nieuwbouw (new construction), Herbestemming (adaptive reuse), and Interieur (interior design)—supplemented by specialized advisory practices including DuMo Advies (sustainable monuments), bouwhistorisch onderzoek (historical building research), instandhoudingsplannen (multi-year maintenance planning with O-prognose), subsidie advisory, and directievoering (construction supervision). The firm's technical differentiators are domain-specialized expertise in monument conservation, color research, and historical provenance rather than proprietary software, AI/ML systems, or data assets. It holds registered DuMo Advisor status with the Nationaal Restauratiefonds, is a member of the Erfgoed Expert Team and VAWR, and participates in the Rijksdienst voor het Cultureel Erfgoed (RCE) ontzorgingsprogramma and the Province of Utrecht maatschappelijk vastgoed program.

TPAHG generates revenue through project-based professional service fees covering design, planning applications, project supervision, and construction management. Distribution is direct-to-client via professional networks, referrals, public tenders, and active participation in industry associations, with pricing varying by project scope and complexity. The firm has no disclosed funding rounds, subsidiaries, M&A activity, or external shareholders, and operates as an independent Dutch BV.
