What Konzept4 AG does
Konzept4 AG is a privately held Swiss construction management and architecture firm headquartered in Sarnen, Obwalden, founded on January 1, 2016 through the merger of PLANIG GmbH and Andi Burch Architektur. The firm operates with a team of eight employees across three members of management (Andi Burch, Urs Gasser, Markus Amrhein) plus project managers, junior construction managers, technicians, CAD draftsmen, an apprentice, and administrative staff, offering an integrated service across four pillars: Baumanagement (construction management and site supervision), Projektentwicklung (project development and feasibility), Bauherrenvertretung (fiduciary client representation), and Architektur (architectural design). Core technology is limited to standard industry tooling, with CAD for drafting and BIM capabilities (Christina Janser holds a BIM Manager credential), without any disclosed proprietary software, AI/ML systems, or platform architecture.
The firm serves property owners, cantonal and municipal government entities, commercial and hospitality businesses, and individual homeowners across central Switzerland, primarily in Obwalden and adjacent cantons such as Nidwalden. Named clients include Kanton Obwalden (Psychiatry Obwalden renovation, 2022-2025), Obwaldner Kantonalbank AG (new HQ, 2017-2021), Bürgenstock Hotels AG, Frutt Living AG (CHF 9.0 million renovation, 2020-2024), Einwohnergemeinde Sarnen (school renovation, CHF 5.0 million), and charitable clients such as the Beatrice Zai Foundation (Myanmar orphanage, 2023).
Konzept4 operates a relationship-driven, sales-led B2B professional services model with project-specific pricing, multi-year contracts, and direct client engagement. Go-to-market relies on regional reputation, referrals, a project portfolio website, LinkedIn and Instagram presence, and a structured lead channel through a RE/MAX Immobilien Sarnen partnership. The firm is founder-owned with no external investment or venture funding disclosed; revenue is not publicly disclosed.
