Züst Gübeli Gambetti Architektur und Städtebau

What Züst Gübeli Gambetti Architektur und Städtebau does

Züst Gübeli Gambetti Architektur und Städtebau AG (Z2G) is a privately held Swiss architecture and urban planning firm founded in Zürich in 2010 by Roman Züst, Michel Gübeli, and Andrea Gambetti. The firm operates across the full project lifecycle — from feasibility studies, cooperative planning procedures, and master plans through to detailed design, general planning, and execution planning — for residential, mixed-use, and institutional clients. Service offerings span architecture, urban planning, interior architecture, project development, and (via the wholly-owned subsidiary Züst Gübeli Gambetti Generalplanung AG) integrated general planning. The firm employs 94 professionals (54% ETH or HTL/FH trained), uses BIM as its core digital methodology, and has delivered more than 860 projects across 15 years, including 48 competition wins and projects certified under Minergie, Minergie-P, Minergie-P-Eco, and SNBS Silver standards.

The business model is project-based, professional-services revenue derived from architecture commissions structured per SIA planning phases (Phases 31–41) or as a percentage of construction cost. Go-to-market is sales-led and relationship-driven: Z2G acquires mandates primarily by winning open and invited architectural competitions, participating in total-contractor (Gesamtleistungswettbewerbe) procedures, and securing direct commissions from repeat clients. Customer segments include private and institutional real estate developers (e.g., Artisa, Merbag, SI Specogna, Surber Immobilien, Neugut Immobilien, Waldegg Knöpfli), institutional asset managers (Swiss Life Asset Management, UBS Fund Management, Zürich Anlagestiftung), housing cooperatives, and municipalities and public institutions (e.g., Lycée Français de Zurich). Operations are concentrated in the Zürich metropolitan area with emerging presence in Biel.

Technically, Z2G differentiates through specialisation in urban densification, mixed-use integration, office-to-residential conversion, and innovative materiality — notably participation in the Innosuisse 'Think Earth' flagship project led by ETH Zürich to develop clay-wood (Lehm-Holz) hybrid construction for multi-storey residential buildings, and the Kibako timber micro-housing concept in Kloten. The firm maintains no external investors, operates without a digital product or SaaS offering, and channels client acquisition primarily through competition success and repeat institutional mandates rather than paid marketing.
