Martin Lenz AG

What Martin Lenz AG does

Martin Lenz AG is a privately held Swiss real estate development and construction services firm headquartered in Baar, Canton Zug, founded on September 1, 1999 by Martin Lenz sen. and his wife Gertrud Lenz. The company operates as a general contractor (Generalunternehmer), total contractor (Totalunternehmer), project developer (Projektentwicklung), and project/construction manager (Projekt- und Baumanagement) for residential, commercial, and industrial projects across German-speaking Switzerland. Its service portfolio spans the full development lifecycle from site identification and conceptual planning through to new construction, conversions/renovations, and post-completion property rental (Immobilienvermietung), with a particular emphasis on sustainability-focused renovations and modern building technologies such as heat pumps, photovoltaic systems, and ZEV (Zusammenschluss zum Eigenverbrauch) configurations.

The firm's commercial model is differentiated by its 'Offene Abrechnung' (Open Billing) collaboration model, under which clients retain decision authority over trade contractor selection and benefit from transparent insight into quotes and invoices while delegating development and execution to the company; clients additionally share in any cost underspend generated by Martin Lenz AG's procurement volume and efficient planning. Revenue is generated via fixed-price GU contracts, single-contract TU mandates, and project-based professional services fees for development and management work, all priced on a project-specific quote basis with no publicly disclosed rates. Distribution is entirely direct — the company engages private Bauherrschaften, institutional investors, housing cooperatives, commercial/industrial clients, and government entities (e.g., Korporation Baar-Dorf, Gebäudeversicherung Zug) without intermediary channels.

The company is led in its second generation by brothers Martin Lenz (Head of Development and Realization, Architekt BA / MAS Baumanagement FHZ) and Manuel Lenz (Head of Real Estate and Finance, M.A. HSG), with founder Martin Lenz sen. serving as Chairman of the Board and Head of Project Development. The team of approximately 25 employees includes federally certified construction managers, architects, fire-safety specialists, and dedicated heads of finance, administration, ICT/digitalization, and real estate/marketing functions. Notable clients and projects include KIRKBI Real Estate (ECOPARK Tivoli renovation, 20,259 m2 / 113,534 m3), Stiftung Natur- und Tierpark Goldau, Aeschbach Chocolatier AG, Brauerei Baar AG, and multiple housing cooperatives; the firm reports a portfolio of 100+ completed projects across cantons including Zug, Zürich, Aargau, Schwyz, and Luzern. No revenue, funding, or M&A data is publicly disclosed.
