Charlottenburger Baugenossenschaft

What Charlottenburger Baugenossenschaft does

Charlottenburger Baugenossenschaft eG (operating as 'Charlotte') is a member-owned housing cooperative founded in 1907 and headquartered in Berlin. It manages over 8,000 residential and commercial units (with one source citing 7,000+ residential units following a 2026 Steglitz acquisition) across the Berlin districts of Charlottenburg, Spandau, Reinickendorf, Steglitz, Adlershof, and Siemensstadt, served by approximately 130 employees. The cooperative generates revenue through Nutzungsgebühren (recurring usage fees) paid by members at fair, socially-missioned rates, with profits reinvested into maintenance, modernisation, and new construction rather than distributed to shareholders; ancillary revenue streams include guest apartments from €50/night and community activity fees such as yoga at €20/month and senior movement classes at €5/session.

The core technology platform is the CHARLOTTE1907 member portal, a 24/7 self-service application powered by Aareon CRM that handles tenant management, personal data updates, and member communication, supplemented by Nexi payment processing at the property offices and ConsentManager for GDPR compliance. Around the housing product, the cooperative operates a layered service ecosystem: CHARLOTTE | Treffs community centres (with over 50 weekly activities across multiple Berlin locations), CHARLOTTE | Sozial social counseling (covering Charlottenburg/Steglitz/Wilmersdorf/Adlershof, Spandau, and Reinickendorf/Weißensee), a Nachbarschaftsfonds neighbourhood fund (up to €1,907 per application), six guest apartments, and a 'Lebenslanges Wohnen' (lifelong living) program delivered in partnership with SENIOVO for barrier-reducing home modifications. The cooperative is governed by a Vorstand (Dirk Enzesberger and Carsten-Michael Röding) and an Aufsichtsrat chaired by Peter Lobanow, with industry representation through BBU Verband Berlin-Brandenburgischer Wohnungsunternehmen, GdW Bundesverband, WBG Berlin, and Genossenschaftsforum. Membership-based housing assignment, weekly online apartment listings, and digital self-service form the customer acquisition and retention mechanics; distribution is exclusively direct-to-member via three house administrations (Hausverwaltungen) and the cooperative's own digital channels, with no intermediaries or third-party resellers.
