What Holzbau Bruno Kaiser Gmbh does
Holzbau Bruno Kaiser GmbH is a German timber construction general contractor founded in 1986 and headquartered in Bernau im Schwarzwald, Black Forest region. The company designs and builds ecological timber buildings — single-family homes, multi-family residential buildings up to eight stories, commercial and hospitality projects, plus renovations and historic Black Forest farmhouse restorations — for private families, housing cooperatives, real estate investors, and commercial clients. Construction is delivered turnkey (Schlüsselfertig) using the company's own timber construction methods including Holzrahmenbau (timber frame), Holztafelbau (timber panel), Holzskelettbau (timber skeleton), and Massivholzbau (solid wood), supported by an in-house Schreinerei (joinery) with a CNC machining center producing kitchens, stairs, furniture, and interior fit-out elements.
The company generates revenue primarily through project-based construction contracts priced individually per scope, with regional timber sourcing from Baden-Württemberg forests as a stated sustainability and quality differentiator. Sales are direct (sales-led) via website inquiry forms, showroom consultations at the Bernau HQ, and participation in trade events such as GETEC and Praxistage.HOLZ. Customer base spans private SMB homeowners (primary), real estate investors and housing cooperatives (primary), commercial/hospitality businesses, and historic property owners. The business is privately held, founder/management-owned with no external institutional capital, operates under managing directors Herbert Duttlinger and Andreas Wiesler (both promoted from within), and is accompanied by subsidiary Holzbau Südwest GmbH founded in May 2023 for regional expansion in southwestern Germany.
