Stephanswerk Wohnungsbaugesellschaft mbH

What Stephanswerk Wohnungsbaugesellschaft mbH does

Stephanswerk Wohnungsbaugesellschaft mbH is a church-affiliated housing construction and property management company headquartered at Klusstraße 3, 49074 Osnabrück, Germany, founded in 1949 by Bishop Hermann Wilhelm Berning to address the post-war housing crisis. The company operates under the trusteeship of the Bistum Osnabrück (Diocese of Osnabrück) and the Bischöflicher Stuhl zu Osnabrück (Episcopal Chair of Osnabrück), with a regional mandate serving the Diocese of Osnabrück area. It manages approximately 3,300–3,400 residential and commercial units in its own portfolio and provides third-party property management services (rental management, WEG-Verwaltung, fiduciary management).

The company's revenue model combines four streams: recurring rental income from its owned portfolio, one-time property sales of newly built barrier-free ownership apartments (Eigentumswohnungen), recurring third-party property management fees, and professional construction and architecture services for church parishes and charitable institutions. Sales and rental units are listed via the company's own website (stephanswerk.de) and the ImmobilienScout24 marketplace, while construction projects are sourced through direct relationships with Catholic parishes and Wohlfahrtsverbände (welfare associations) such as Caritas, SKM, and social service providers. The company is differentiated by expertise in KfW 40/40+ energy efficiency, Passivhaus standards, and barrier-free design, with a focus on affordable and social housing including Wohnberechtigungsschein-certified units.

The customer base spans private tenants and buyers across the Osnabrück region, church parishes commissioning parish centers and community facilities, and charitable institutions developing kindergartens, senior care homes, and social housing. Strategic priorities include KfW-standard energy-efficient construction, social infrastructure build-out (e.g., Marienkita Schwege, Haus Sankt Joachim, Mutter-Kind-Haus St. Anna), and multi-family residential projects such as the 19-unit Bissendorf-Schledehausen development and the Quartier 21-L master-planned neighborhood. Operationally, the company is governed by a supervisory board chaired by Reinhold Kassing, with leadership shared between commercial managing director Andreas Engelmeyer (appointed July 2025) and technical managing director Carolin Lauhoff.

Broad incumbents

• LEG Immobilien AG: Publicly listed North Rhine-Westphalia residential property company (~130,000 units). Comparable core business of residential rental and management, but operates at much larger scale and on a commercial — not mission-driven — basis.
• Vonovia SE: Europe's largest residential real estate company (~500,000 German units) providing rental, property management, and development services. Provides public-market benchmark for residential portfolio valuation and unit economics.

Direct peers
