Grund und Grün GmbH

What Grund und Grün GmbH does

Grund und Grün GmbH is a privately held German real estate company headquartered in Düsseldorf, founded in 2008 by John Bothe (originally operating as Silberlake Real Estate Group GmbH before rebranding in February 2025). The company operates as both a long-term investor in residential and commercial real estate and a digital service platform, with its operating geography focused on North Rhine-Westphalia. Through its wholly owned subsidiary Pro Haus Plus GmbH (formerly RSG Residential Management GmbH), it provides third-party property management services for institutional and private property owners.

The company pursues a 'Manage-to-ESG' strategy centered on a proprietary digital platform that integrates service providers and ESG reporting structures into a single ecosystem, supported by a 'ten specialized building blocks' methodology for property management. Active project developments include the Möllenkotterquartier in Schwelm (151 units, ~10,030 sqm, with ~€10.3 million in NRW subsidized funding under Modernisierungsoffensive+), plus developments in Düsseldorf on Siegfriedstraße, Dorotheenstraße, Belsenstraße, Höhenstraße, Krahestraße, and Zietenstraße. The firm states it manages or has developed over 20,000 residential units (35,000 per English-language site) and approximately 700,000 sqm of rental space, with disclosed investment volume exceeding €100 million.

Revenue is generated through three primary streams: recurring property management fees (including the Orange Capital Partners ~7,000-unit mandate acquired March 2025), one-time project development revenue from property sales and modernization value creation, and investment returns from own-balance-sheet portfolio appreciation and rental income. Distribution is direct-to-B2B via enterprise sales to property owners and institutional investors, supplemented by institutional partnership mandates and public-sector subsidy programs (NRW Bank, Volksbank). Customer segments span institutional investors, private property owners, property sellers, and end-buyers of developed residential units, with no public pricing disclosure.

Broad incumbents

• Vonovia SE: Vonovia is Europe's largest residential real estate company with ~568,000 units across Germany. It is a broad incumbent peer offering overlapping residential property management, modernization, and ESG-driven retrofit services at national scale, but operates far more broadly than Grund und Grün's regional, ESG-niche focus.
• Deutsche Wohnen SE: Deutsche Wohnen is a major German residential landlord (~140,000 units, now part of Vonovia) operating in Berlin and other major cities. Comparable as a broad German residential incumbent with overlapping property management and ESG retrofit operations.
• Aroundtown SA: Aroundtown is a major European real estate company with significant German residential and office exposure. Comparable as a broad German real estate incumbent with portfolio management and value-add operations, though operating at much larger scale and a broader asset mix.

Direct peers

• Grand City Properties S.A. Grand City Properties owns and manages ~60,000 residential units primarily in Germany, with a value-add repositioning strategy in urban areas. Comparable as a mid-sized German residential investor/manager pursuing operational improvements and modernization similar to Grund und Grün's playbook.
• CORESTATE Capital Holding S.A. CORESTATE is a Germany-based real estate investment manager with residential and commercial mandates. Comparable as a German real estate investment/management platform pursuing institutional mandates and fund structures similar to Pro Haus Plus's third-party management model.
• Accentro Real Estate AG: Accentro is a German residential real estate company focused on portfolio acquisitions, privatization of rental apartments, and value creation in German residential — a comparable mid-sized strategy of buying, repositioning, and selling German residential assets.
• LEG Immobilien SE: LEG Immobilien is Germany's largest NRW-focused residential real estate company with ~166,000 units. It is the closest direct peer given the shared North Rhine-Westphalia geographic focus, residential portfolio composition, and institutional investor base — both compete for NRW portfolio mandates and tenant demographics.
• TAG Immobilien AG: TAG Immobilien is a German listed residential real estate company with ~85,000 units focused on secondary and tertiary cities. Comparable as a mid-sized residential investor/manager pursuing value-add modernization in regional German markets similar to Grund und Grün's NRW focus.
• Adler Group SA: Adler Group is a German-listed residential real estate company whose NRW portfolio was acquired by Orange Capital Partners and is now managed by Pro Haus Plus. It is a directly comparable peer in the same residential sub-segment and asset class; Grund und Grün now services assets formerly held by Adler.

Others

• Aareon AG: Aareon is a leading European PropTech vendor providing software for residential and commercial property management. Comparable as an ecosystem/adjacent player whose digital property management tools could either compete with or integrate into Grund und Grün's Manage-to-ESG platform offering.
