What Isaria Munich Project Development does

The company is a German real estate development and construction firm, referred to in associated data as QUARTERBACK Immobilien AG (a related or affiliated entity under the same data record). The firmographic record identifies Isaria Munich Project Development as a München-based project development company for residential construction, founded in 1994, with 51-100 employees. The associated corporate data describes a holding structure founded in 1993 in Delitzsch near Leipzig that unites multiple real estate companies under one umbrella, with operations spanning eight German metropolitan areas (Leipzig HQ, Dresden, Erfurt, Potsdam, Berlin, Munich, Cologne, Frankfurt, Hamburg). The integrated group combines project development (QUARTERBACK Projekt), property management (QUARTERBACK Service), energy solutions (QUARTERBACK Energy), and affiliated companies (Verbundene Unternehmen) into a single platform that covers the full real estate value chain from project conception through construction, asset management, and ongoing property administration.

Pricing is project-specific and not publicly disclosed. The go-to-market approach is sales-led and direct, with regional offices handling negotiations with municipal housing companies (e.g., WBM Berlin-Mitte), institutional investors (e.g., HIH), and private buyers. Customer segments include municipal and social housing providers (primary), private residential buyers and renters (primary), commercial tenants, and institutional real estate investors. Recent major project deliveries in 2025-2026 include the Darwinbogen quarter in Königs Wusterhausen (HIH partnership), the Ostravorwerk social housing project in Dresden, the Chopin Spitze II project in Leipzig, and the Landsberger Allee 315 project in Berlin (WBM Berlin-Mitte partnership).
