HolzHaus Bonndorf GmbH

What HolzHaus Bonndorf GmbH does

HolzHaus Bonndorf GmbH is a family-owned prefabricated timber construction company headquartered in Bonndorf im Schwarzwald, Germany. Founded in 1995, the company designs and builds custom timber-frame single-family homes, multi-family residential buildings, commercial structures, and modular building products for private homeowners, real estate developers, and hospitality operators primarily in Baden-Württemberg and German-speaking Switzerland. The company operates an integrated in-house joinery workshop (Schreinerei) and employs nearly 100 specialists across carpentry, planning, construction management, customer service, and architecture. As of June 2026, the company is operating under preliminary insolvency proceedings (vorläufiges Insolvenzverfahren) filed at Amtsgericht Waldshut, following a significant decline in new orders and a March 2026 management transition.

The company's core technology is the proprietary HolzrahmenbauPlus NATURpur wall assembly, which uses 30mm GFM white fir/spruce solid wood planks mechanically joined with traditional Schwalbenschwanz (dovetail) connections, eliminating adhesives and films. Construction is DIBt-approved and RAL-certified with third-party monitoring by GDF and QDF, and uses PEFC-certified timber sourced within approximately 100km of the production facility. Standard energy performance is KfW 40 (approximately 60% below legal requirements), with optional QNG-Plus certification that unlocks KfW subsidies of up to €150,000 per residential unit. The integrated model covers consultation, energy consulting, architectural planning, CNC production, on-site assembly, and after-sales service from a single provider.

HolzHaus Bonndorf generates revenue through one-time project-based sales across three primary streams: custom timber house construction (single-family to multi-family), modular building sales (Minimodul, Wohnmodul, Büromodul, Hotelmodul with starting prices from €175,000–€210,000), and standalone custom carpentry services. Distribution is exclusively direct field sales with no third-party retail, supported by a Swiss representative (Ruedi Sorg) and a closely integrated developer partnership with MAWO Immobilien GmbH, whose Geschäftsleiter Florian Hegar also manages a commercial division at HolzHaus Bonndorf.

Revenue model

1. Custom Timber House Construction: HolzHaus Bonndorf generates revenue through the sale of individually planned and custom-built timber houses, ranging from single-family homes to multi-family residential buildings and commercial/industrial constructions. Revenue is project-based and one-time at point of sale. The company provides full-service delivery from consultation, architectural planning, energy consulting, production, assembly, and after-sales service under one roof. A significant portion of revenue is derived from project developer channel partners (e.g., MAWO) commissioning multi-unit residential buildings.
2. Modular Building Sales: Pre-fabricated modular timber buildings sold as turnkey solutions. Standard product lines include: Minimodul (from €210,000), Wohnmodul residential module (from €175,000), and Büromodul office module (price on request). Modules are configured and combined per customer requirements and can be expanded or re-purposed over time.
3. In-House Carpentry & Interior Services: Custom carpentry services for stairs, kitchens, bathrooms, furniture, and commercial/gastronomy interiors, delivered both as part of HolzHaus construction contracts and as standalone services to external customers. Pricing and delivery are project-specific.
