Allgemeine Deutsche Schiffszimmerer-Genossenschaft eG

What Allgemeine Deutsche Schiffszimmerer-Genossenschaft eG does

Allgemeine Deutsche Schiffszimmerer-Genossenschaft eG (DBA "Die Schiffszimmerer") is a Hamburg-registered Wohnungsbaugenossenschaft — Germany's oldest housing cooperative, founded in 1875 — that provides rental housing to its members on a not-for-profit, member-owned basis. The cooperative owns and operates a portfolio of 9,034 apartments across more than 40 Hamburg neighborhoods (including HafenCity, Dulsberg, Moorkamp, and Wilhelmsburg), serving 17,408 members who hold cooperative shares and pay "Nutzungsgebühren" (occupancy charges) under the "Wohnwertmiete" value-based rent model rather than market rents. Allocation follows cooperative rules and member seniority, and members hold voting rights in the Vertreterversammlung. Beyond core apartment rental, the cooperative offers Gästewohnungen (guest apartments), digital Schadensmeldung/Notdienst, neighborhood development (Quartiersentwicklung), and member engagement via the journal, email newsletter, "bei uns" member magazine, and social channels.

The GTM motion is direct-to-consumer in a structural sense: prospective applicants are routed through the website's non-member Wohnungsanfrage (with SCHUFA credit checks) and converted to member status; existing members manage housing requests, appointments, and services through the Mitglieder-Portal (portal.schiffszimmerer.de) and a Terminbuchung system. The technology layer is conventional cooperative-management software with member-facing web portals — there is no API offering, no AI/ML component, and no proprietary platform productized beyond internal use. The cooperative is BITV 2.0-tested (May 2025, with improvements slated for end-2025), DSGVO- and TDDDG-compliant, and affiliated with VNW (Verband norddeutscher Wohnungsunternehmen) as its legally mandated Prüfungsverband. As an eingetragene Genossenschaft, the entity is member-owned, not publicly traded, with no parent company and no subsidiaries; governance rests with a two-member Vorstand (Matthias Saß, Thomas Speeth) supervised by an Aufsichtsrat chaired by Arne Brügmann.

Revenue is generated almost entirely from occupancy fees on the owned housing stock, with ancillary income from guest apartments, parking, and member services; per-apartment economics are gated by cooperative law rather than market rents. Revenue figures are not publicly disclosed in the scraped sources (Geschäftsbericht 2023 and 2025 PDFs are referenced but not parsed). Headcount is reported as "over 100" on the careers page while the firm's compiled profile lists 26 employees; the higher figure is more consistent with a portfolio operator of 9,000+ units and is treated as authoritative here. Geographic scope is exclusively the Hamburg metropolitan area, with no signaled expansion beyond it.

Regional players

• GWG München: Munich-based housing cooperative operating tens of thousands of member-owned rental apartments under the same Genossenschaft model. Direct comparable structure (member-owned, below-market rents, neighborhood focus) but focused on the Munich market rather than Hamburg.
• Bauverein München eG: One of Munich's oldest housing cooperatives, providing member-owned rental housing with a comparable genossenschaftliche value proposition. Highly comparable governance and business model, but operates in Munich, not Hamburg.
• Wohnungsgenossenschaft Mehringplatz eG: Berlin-based housing cooperative managing member-owned rental units. Comparable as a German Wohnungsbaugenossenschaft with similar member-governance, value-based rent, and community-focused operating model, though at smaller scale and in Berlin.

Broad incumbents

• LEG Immobilien AG: Large listed German residential real estate company focused on North Rhine-Westphalia with over 160,000 units. Comparable business model (residential rental lessor) and overlapping member-base demographic, but operates in a different region and as a listed for-profit entity.
• ADLER Group SA: European-focused residential real estate company with a significant German rental portfolio. Comparable as a large-scale residential lessor with similar tenant profile, though operating across multiple European markets and as a listed for-profit entity.
• Vonovia SE: Germany's largest listed residential real estate company with roughly 500,000+ apartments nationwide. Broad incumbent in the same residential rental category with overlapping target market, but operates as a for-profit listed REIT rather than a cooperative, and is geographically diversified across Germany rather than Hamburg-focused.
• Deutsche Wohnen SE: Major German listed residential property company with a portfolio concentrated in Berlin and other urban centers. Comparable as a large-scale residential lessor with similar tenant base, but operates for-profit across multiple cities with significant recent M&A activity.

Direct peers

• SAGA Siedlungs-Aktiengesellschaft Hamburg: Hamburg's municipal housing company and one of Germany's largest residential landlords, managing over 130,000 apartments primarily in Hamburg. Direct peer because it operates at massive scale in the same Hamburg residential rental market, serving comparable affordable-housing demand with a parallel ownership/governance model.
• Wohnungsbaugenossenschaft Hamburg-Wandsbek eG: Another Hamburg-based Wohnungsbaugenossenschaft managing member-owned rental apartments in the same city. Direct peer operating under the same legal framework, with the same target tenant base, same VNW affiliation, and directly competing for member acquisition and housing demand in Hamburg.

Others

• hamburger wohnungsbaugenossenschaften eG (Hamburger Genossenschaftsverband): Cooperative umbrella/audit association for Hamburg-based housing cooperatives. Comparable ecosystem participant and industry body alongside VNW; not a direct operator peer but a structural peer that defines the regulatory and audit framework the subject cooperative operates within.
