What HGA ARCHITECTURE does
HGA - Herbiet Grosch Architecture is a private Belgian architecture firm founded in 2011 by Christian Herbiet and Laurent Grosch, operating as a Société à responsabilité limitée (SRL) headquartered in Sprimont, Wallonia. The firm provides complete architecture and urban planning services organized across nine interconnected service domains: Habiter (residential), Soigner (healthcare), Travailler (office), Produire (industrial), Partager (hospitality), Divertir (leisure), Commercer (retail), Ambiancer (interior design), and Urbaniser (urban planning). HGA delivers full project management from conception through completion, serving property developers, healthcare institutions, municipalities, and private individuals across the Wallonia region and broader Belgium.
The firm operates as a small boutique practice with a team of 11 architecture professionals including founders, architects, an engineer-architect, drafters, and assistant architects. Revenue is generated through professional service fees structured as percentages of construction costs or fixed project fees, billed on a per-project basis with multi-year contract durations. Notable engagements include the 52,600 m² CHU de Liège parking infrastructure, the R Hôtel 4-star hospitality complex (5,800 m²), the Plopsaqua Hannut aquatic park (8,000 m²), the 100-bed Le jardin des Chantoirs retirement home, and the Thimister Cidrerie eco-quarter development (165–184 units on 4.69 hectares). The firm's core technology consists of standard industry architecture and design software; no proprietary AI, data, or platform technology is disclosed.
HGA's go-to-market is sales-led, relying on direct client engagement, professional network referrals, and public tender participation rather than marketing or digital channels. The firm maintains a portfolio website but operates with no external funding, no parent company, no subsidiaries, and no public listing. Repeat-client relationships—particularly with developer ELOY across residential, healthcare, and commercial projects, and institutional clients like CHU de Liège and Plopsa—constitute the primary commercial pipeline, supplemented by partnerships with engineering consultancies (Lemaire Ingénieurs, BICE, Gesplan) that provide structural and civil engineering coordination on a project basis.
