Gebäude- und Wohnungsbaugesellschaft Wernigerode mbH

What Gebäude- und Wohnungsbaugesellschaft Wernigerode mbH does

Gebäude- und Wohnungsbaugesellschaft Wernigerode mbH (GWW) is a municipal housing company wholly owned by the City of Wernigerode, founded in March 1991. It manages approximately 3,000 residential units and 176,000 sqm of living space across Wernigerode's main neighborhoods (Altstadt, Burgbreite, Stadtfeld, Harzblick, Hasserode, Benzingerode), housing roughly 22% of the town's ~34,000 residents, alongside 28 commercial units including the Volkslichtspiele cinema, the Fürstlicher Marstall, Krummelsches Haus and various office/retail spaces. The company also operates specialized housing products for students (near Hochschule Harz), seniors (with care-service partnerships via Diakonie and DRK), and vacation rentals (Ferienwohnungen via booking.com).

GWW's core platform is integrated municipal real-estate management: a direct-to-tenant Wohnungsfinder (property search) and Aareon CRM tenant portal handle leasing and account management, with listings syndicated to ImmobilienScout24. An in-house Regiebetrieb team (carpenters, electricians, painters, Hausmeister) and a 24/7 Havarieservice handle maintenance internally. The differentiating technical capability is the Sonnenhaus concept — the first multi-family solar house in Saxony-Anhalt, with per-apartment PV assignment enabling up to 50% ancillary-cost savings and ~36 tonnes annual CO2 reduction. GWW additionally acts as Bauherr (developer) for public and mixed-use projects, including the August-Hermann-Francke-Grundschule, the Lutherkarree (€13.9M, 38 units, completed 2025), the Casa Verde sustainable development, and a planned rehabilitation clinic in partnership with GSW.

Revenue is overwhelmingly recurring monthly rental income from residential (~3,000 units at warm rents ranging €350–€1,517), supplemented by commercial leases, advertising sales via the 72 sqm HarzHorizont LED billboard (32,000+ daily contacts), and tourism rentals. Capital projects (e.g., Lutherkarree) generate future rental income rather than development fees. As a 100% municipally owned entity with a social mandate (Sozialauftrag), GWW prioritizes broad-population housing provision over yield maximization, and reinvests surpluses into modernization — targeting full energy-renovation of its Plattenbau stock by 2030.

Revenue model

1. Residential Rental Income: GWW generates the majority of its revenue from renting approximately 3,000 residential units across Wernigerode. Rental income is the primary revenue stream. Rent is charged on a monthly basis, with ancillary costs (Nebenkosten) billed separately.
2. Commercial Rental Income: GWW leases approximately 28 commercial units including a cinema (Volkslichtspiele Wernigerode), the Fürstlicher Marstall, Krummelsches Haus, a café, a creative loft with co-working spaces, practice and office spaces. This is an additional recurring revenue stream alongside residential rentals.
3. Vacation/Ferienwohnung Rental: GWW rents out vacation apartments (Ferienwohnungen) including a 3-bedroom apartment in the city center with views of Wernigerode Castle and Brocken, and a renovated apartment at Am Salzbergtal. Bookings are handled via booking.com and direct contact.

Local and regional businesses can purchase advertising slots. Approximately 300 daily airings per advertising company.
5. Property Development / Construction as Bauherr: GWW acts as developer and construction client (Bauherr) for major building projects including the August-Hermann-Francke Grundschule, the rehabilitation clinic, Lutherkarree (€13.9M), and the Sonnenhaus. These are capital expenditure projects that generate rental income upon completion rather than direct development fees.
6. Havarieservice and Maintenance Services: GWW provides around-the-clock emergency repair services (Havarieservice) and in-house maintenance through its Regiebetrieb team (carpenters, electricians, painters, general maintenance staff). Revenue is bundled into operating costs rather than charged as a separate line item to tenants.

Direct peers

• GESOBAU AG: Berlin municipal housing company managing ~45,000 units, wholly owned by the State of Berlin. Direct peer in business model: city-owned residential landlord, in-house Regiebetrieb-style maintenance, and social mandate serving all income levels.
• STADT UND LAND Wohnbauten-Gesellschaft mbH: Berlin municipal housing company with ~52,000 units. Closely mirrors GWW's structure: municipal GmbH, in-house trades organization, broad residential portfolio plus commercial units, social housing mandate.
• WBM Wohnungsbaugesellschaft Berlin-Mitte mbH: Berlin Mitte district-owned housing company with ~28,000 units. Same legal structure (municipal GmbH) and mission as GWW: develop, manage, and maintain rental housing with a social mandate.
• SAGA Siedlungs-Aktiengesellschaft Hamburg: Municipal housing company owned by the Free and Hanseatic City of Hamburg, managing ~135,000 units. The closest structural analog to GWW: publicly owned German housing company with a social mandate, in-house maintenance, and broad tenant services — GWW is a much smaller municipal counterpart.
• Nassauische Heimstätte Wohnungs- und Entwicklungsgesellschaft mbH: State-owned housing company in Hessen managing ~50,000 units. Comparable municipal/state-owned residential landlord with development activity and social mandate, though at a larger regional scale than GWW's single-city footprint.
• Bauverein München Haidhausen (BVV): Munich's municipal housing foundation managing tens of thousands of units. Comparable as a German municipal housing provider with a similar mix of residential management, in-house services, and development activity.

Broad incumbents

• Vonovia SE: Germany's largest residential landlord with ~500,000 units nationwide. Comparable as a large-scale institutional residential rental operator, though privately held municipal portfolios like GWW operate at a much smaller, community-anchored scale and serve a social mandate rather than an investor return target.
• Deutsche Wohnen SE: Major German residential real estate company focused on urban rental housing. Comparable product/category (residential rental management) but operates at metropolitan scale in Berlin and other major cities, whereas GWW is concentrated in a single mid-sized Harz city.
• TAG Immobilien AG: Listed German residential property company with ~84,000 units focused on northern and eastern Germany including the former East German regions. Overlaps with GWW on East German residential markets but operates as a publicly traded investor, not a municipal landlord.

Others

• Aareon AG: GWW's CRM/property management software vendor powering the tenant portal. Included as an enabling ecosystem participant — not a competitor, but the underlying digital infrastructure on which GWW's direct-to-tenant model depends.
