Erni Gruppe - Erni Holzbau AG / Erni Planung AG

What Erni Gruppe - Erni Holzbau AG / Erni Planung AG does

Erni Gruppe is a privately held Swiss construction group headquartered in Schongau, Canton of Lucerne, founded in 1989. The group operates as a vertically integrated timber construction provider through four wholly-owned subsidiaries: Erni Holzbau AG (timber construction), Erni Planung AG (planning and design), Erni Realisation AG (general/total contracting), and Erni Agrar AG (agricultural constructions including wooden slurry pit covers). The company delivers projects across three customer segments — private homeowners, architects and engineers, and agricultural clients — primarily in Central Switzerland and Aargau.

The core technology stack combines traditional carpentry with modern prefabrication. Production takes place in a 14,000 sqm facility in Schongau featuring CNC-controlled equipment, including a newly installed WEINMANN 4-table system from HOMAG in the renovated Hall 4. Planning is supported by 3D visualization and Building Information Modeling (BIM). Service offerings span the full construction lifecycle: planning (concept, permits, construction management), structural and facade timber construction, in-house metalworking (Spenglerei), interior finishing including stairs and joinery (Ausbau), and full general/total contracting (Realisation) with fixed-price agreements.

The business model is project-based with single-occasion revenue recognition per construction project. Pricing is quote-based and project-specific, with no public pricing tiers. The go-to-market is sales-led and relationship-driven, anchored by a single competent contact person across all project phases plus local presence through trade exhibitions and a real estate marketplace. The owner-operated firm (Peter Henggeler) employs 115 people plus 21 apprentices and holds VGQ certification awarded in June 2026.
