Wanner & Lott

What Wanner & Lott does

Wanner & Lott AG is a family-rooted Swiss construction services company headquartered in Regensdorf, Zürich, founded in 1982 by Heinz Wanner and operating since 1990 as a joint-stock company (Aktiengesellschaft) following the partnership with Fredi Lott. The firm specializes in renovation, conversion, restoration, and concrete repair rather than new construction, organized around five service lines: Umbauen (conversion), Renovieren (renovation), Sanieren (remediation including concrete repair and waterproofing), Kundenmaurer Service (responsive customer mason service for homeowners), and Historisch Restaurieren (heritage restoration of listed buildings). Notable technical capabilities include specialized concrete repair with surface protection systems, rigid and elastic waterproofing, crack injection, structural reinforcement using steel and CFK lamella, and natural stone restoration with matching period materials (e.g., a CHF 1.5M retirement home project in Fribourg using matched sandstone, and a Kirchgemeinde Guthirt church facade restoration).

The company generates revenue through project-based construction contracts with fixed pricing by scope, spanning small repair jobs (from CHF 2,000) up to major renovations (CHF 2.2M for the Theater Basel facade). Customers span private homeowners, commercial property owners, real estate management firms, and institutional/heritage clients — evidenced by named projects for Theater Basel, Altersheim Birkenrain, Alexandra Immobilien AG, Zoo Zürich AG, Kirchgemeinde Guthirt, Fondation la Poype-EMS, and Quinn Immobilien AG. The GTM is direct-to-consumer for the greater Zürich area, with distributed direct sales (phone, inquiry forms, project references) and no intermediary channels. The firm employs approximately 75 staff across three physical sites (Regensdorf HQ, Dällikon workshop, Buchs workshop) and operates an apprenticeship program supporting internal talent development. Current leadership (Daniel Steiner and Gregor Knecht, in place since 2014) represents a completed multi-year succession from the founder's family.
