What concarus Real Estate Invest GmbH does

Concarus Real Estate Invest GmbH is a Berlin-based, family-owned commercial real estate investor and project developer specializing in value-add retail, office, mixed-use, and light-industrial properties across Germany. Founded in March 2010 by Boris Milkov (Managing Director), Laurenz Stief (architect), and shareholders Michael May and Günter Porth, the company operates as the commercial-property arm of the May & Porth Gruppe conglomerate with headquarters at Kurfürstendamm 178-179, Berlin. The company pursues two investment strategies: (i) acquisition of underdeveloped existing assets or land with short-to-mid-term value creation potential, and (ii) acquisition of large-scale commercial properties for long-term hold and development.

The company's core offering is a vertically integrated real estate platform combining acquisition, project development, asset management, property management, and facility management under one roof. It sources opportunities through direct outreach ([email protected]), inbound offers, and institutional networks including advisors such as Colliers and Savills, frequently acquiring assets out of insolvency, from funds (BGP/INTERNOS, Real I.S., Cerberus object companies, Hamborner REIT AG), or off-market. The active portfolio of 15+ properties spans more than 200,000 m² and includes flagship assets such as the heritage-listed Thiemann-Quartier in Berlin-Neukölln (~53,300 m², 15 buildings), Bürocenter City-Süd in Hamburg (~30,000 m², acquired 2015 for ~€52M), Circoleum in Bad Homburg (~21,000 m²), MEZ Gägelow, Kelheimer Einkaufszentrum, Bahnhof-Center Gelsenkirchen, Haerder-Center Lübeck, and Geschäftshaus LiKe 25 in Essen.

Concarus generates revenue primarily through long-term rental income from blue-chip and government tenants (REWE, Land Berlin/Finanzamt, Fresenius, Kaufland, dm-drogerie, Axel Springer, Lego, Netto, MSA Deutschland), supplemented by capital gains on disposition of repositioned assets to institutional buyers (e.g., sales to LBBW Special Fund in 2022 and to BERENBERG Real Estate Berlin fund in 2021). Current development pipeline includes TQ Weser (~14,800 m² of rental space, building permit received December 2024) and TQ Rix (~24,500 m² BGF, pre-approval received July 2024) within the Thiemann-Quartier, anchored by a long-term Land Berlin lease covering ~18,300 m². The company is privately held by the May and Porth families, with no external institutional or private-equity backing evidenced in available materials.
