Acau Architecture

What Acau Architecture does

Acau Architecture is a Geneva-based architecture and urban planning practice founded in 1963 as a cooperative of architects and now operating as acau architecture sa, headquartered in Carouge. The firm provides a full-service offering spanning architecture, urban planning, building information modeling (BIM), and construction project management, serving Geneva-area public-sector clients (communes such as Vernier, Meinier, Lancy, Onex, Chêne-Bourg, Versoix, and Pregny-Chambésy), housing cooperatives, schools, and NGOs. Its project portfolio is dominated by public competitions and institutional buildings, including recent deliveries such as the Maison de Quartier des Libellules (December 2024) and the Sécheron school (August 2025).

The practice operates with approximately 30 staff organized around eight associated partners, with three new partners onboarded in 2025 (Nemitz, Gonzalez, Ait El Kadi). Its core technical stack centers on Autodesk Revit-based BIM extended into 4D/5D workflows, VR visualization for client review, and ArcGIS for urban-scale analysis. In 2025 the firm obtained SIG-éco21 C-BAT certification, formalizing a material-reuse (réemploi) service line that qualifies for Geneva energy-utility subsidies and extends the practice into sustainability-driven mandates.

Revenue is generated through professional fees on architecture and urban-planning mandates, primarily secured via public-sector competitions and direct appointments from institutional clients and housing cooperatives. The 2021 relocation to enlarged Carouge premises and ongoing 2025–2026 hiring in architecture and urbanism indicate a stable, capacity-led growth posture rather than a scale-aggressive one, with the C-BAT credential acting as the principal recent lever to access subsidized réemploi work alongside traditional design fees.

• Meili, Peter & Partner: Swiss architecture practice with comparable multi-disciplinary scope (architecture, urbanism, design) and established public-sector track record — comparable in scale and service portfolio.
• Ferrari Architectes: Established Geneva architecture firm with a comparable mix of public-sector commissions, housing, and urban projects in the Canton of Geneva — directly overlapping in client base and service offering.

Broad incumbents

• Burckhardt+Partner: Major Swiss architecture and general-planning firm with a much broader portfolio across building typologies and geographies — competes with Acau on larger concours but operates at materially greater scale.

Others

• VIMADE Architectes Paysagistes: Geneva-based landscape architecture firm that is an existing implementation partner on Acau's PLQ de l'Ancien-Puits and Place de la Gare de Chambésy projects — comparable Swiss public-sector ecosystem participant rather than a direct competitor.
