Simple Architecture

What Simple Architecture does

Simple Architecture is a privately-held architecture and interior design firm headquartered in Liège, Belgium, serving primarily residential homeowners and select commercial clients across the Wallonia region. The firm operates with a six-person team that combines exterior architecture and interior architecture competencies under the leadership of founders-administrators Yves Franken and Sarah Dassy, alongside architects Inès Ménaert and Fabien Mosen, interior architect Shan Chen, and team member Matthew Allen. Its service offering is organized into three categories: Transformation (renovation, restoration, and extension of existing buildings), Aménagement (interior design, space conception, and custom furniture), and Construction (new builds including single-family homes and specialized facilities such as a healthcare dental center).

The firm's technology footprint is conventional for a small architectural practice: 3D photorealistic rendering and axonometric illustrations are used during sketch phases to help clients visualize future spaces, and design work is supported by partnerships with regional craftsmen (custom carpentry via NAOS Atelier, aluminum frames via Alustyl, and brick suppliers including Wienerberger and MBI/Geostylistix). No proprietary software platforms, APIs, AI capabilities, or digital products are disclosed. Brand presence is maintained through an active Instagram account (@simplearchitecture01) showcasing ongoing projects, a portfolio website (simplearchitecture.be), and a refreshed corporate identity launched in 2025.

Commercially, Simple Architecture operates a sales-led, quote-based professional services model. Pricing is determined after initial consultation and project assessment rather than through published rate cards, billing cadence spans multi-year project lifecycles from programming through construction supervision, and customer acquisition runs primarily through referrals complemented by website inquiries and Instagram reach. With more than 40 projects completed or in progress spanning residential renovations, historic restoration, hospitality interior design, and a co-developed 800 m² dental center, the firm runs as a founder-led regional studio without disclosed external investment, parent company, or institutional ownership.
