The Grounds

What The Grounds does

The Grounds Real Estate Development AG is a publicly listed German residential property developer headquartered in Berlin and traded on the Düsseldorf Stock Exchange's OTC segment Primärmarkt (ISIN: DE000A40KXL9). The company operates a three-pillar business: (i) property development of residential housing — including single-family homes, condominiums, and multi-family buildings — concentrated in Berlin, Potsdam, and Leipzig metropolitan regions, with a distinctive focus on renovating historic Gründerzeit-era buildings alongside new construction; (ii) a steadily growing fixed-asset residential rental portfolio that generates recurring rental income; and (iii) since August 2025, third-party asset management services following the takeover of asset management for companies in the insolvent Ziegert Group.

The company's product surface spans multiple Leipzig condominium developments (Christianstraße 25, Elsterstraße 48, Auguste-Schmidt-Straße 12, Schwarzackerstraße 11, Eisenbahnstraße 149), Berlin-area projects (Potsdam-Fahrland via Semmelhaack, Rauen, Schorfheide, Dallgow-Döberitz), and the Terra Homes sub-brand in Erkner-Hohenbinde, which delivers semi-detached energy-efficient smart homes featuring PVT collectors for combined electricity and heating, EV charging, and KfW-standard energy upgrades. Unit pricing is project-specific, with individual apartments ranging from approximately EUR 142,000 to EUR 870,000 across 26-172 m².

The Grounds is led by a two-person Management Board (Jacopo Mingazzini and Andrew Wallis) and a Supervisory Board chaired by Dr. Peter Maser. The company has 11-50 employees, financed its 2023/2024 expansion with a EUR 17 million corporate bond that was subsequently converted into a hybrid bond in December 2025, and serves two primary customer segments — owner-occupier families and individual property investors — through direct-to-consumer website sales and SEO-optimized property listings. Revenue is not publicly disclosed, and a significantly reduced consolidated loss in H1 2025 is the most recent operating signal.
