Bau- GmbH Roth

What Bau- GmbH Roth does

Bau- GmbH Roth, operating as Roth-Massivhaus, is a privately held German family-owned solid-construction home builder (Massivhaus) headquartered in Berlin-Marzahn with a second office in Berlin-Charlottenburg. Founded in 1998 and led by managing directors André Roth and Enrico Roth, the company has built more than 3,200 homes across a standardized portfolio of 58 house types spanning bungalows, single-family homes, modern houses, city villas, semi-detached houses, multi-generational homes, investor houses, and mini/tiny houses. The company differentiates through free individual planning (Freie Planung) and QNG-certified sustainable construction as the first German massivhaus manufacturer to hold this certification, enabling customers to access KfW government subsidies.

The business model is direct-to-consumer one-time sales of custom-built solid brick homes in Berlin, Brandenburg, and the newly entered Hamburg region. Revenue is generated through individual house contracts, complemented by ancillary services including property search (Grundstücksvermittlung), financing consultation, and investor-focused multi-unit house sales. The go-to-market is sales-led, driven by personal consultations at two Berlin offices, video consultations via Microsoft Teams, WhatsApp messaging, regular house viewing events, and a 2025 webinar program. Standardized inclusive features (3-fold glazing, photovoltaic systems, floor heating, roller shutters, KfW 55/40 EE standards) are bundled into the base price with fixed-price and construction-time guarantees.

Pricing is quote-based and not publicly disclosed, with revenue mixing small/mid-size family homes (131-200 sqm) with higher-value investor houses (295-427 sqm multi-unit builds). The company holds no patents, has no disclosed institutional investment, and operates with no public filings as a registered GmbH in Berlin (HRB 161998 B). Core technology partnerships are with Waterkotte (heat pumps and ventilation) and Schiedel (chimney systems), with regulatory alignment to KfW Bankengruppe subsidy programs and the Bundesministerium für Wohnen, Stadtentwicklung und Bauwesen.
