Haus&haus Immobilien Gmbh

What Haus&haus Immobilien Gmbh does

Haus&Haus Immobilien GmbH is a privately held German full-service real estate company headquartered in Hilden, North Rhine-Westphalia. Founded by managing directors Tatjana Bähr (IHK-certified property valuer) and Burkhard Krohn (former head of private banking at Commerzbank Düsseldorf), the firm operates across four interconnected service lines: real estate brokerage (Immobilienverkauf), property management for both WEG homeowner associations and rental portfolios (Immobilienverwaltung), new-construction project development focused on barrier-free senior housing (Projektentwicklung), and construction financing arrangement (Immobilienfinanzierung). IHK-certified property valuation (Wertermittlung) is offered as a standalone service and free of charge to sellers whose properties the firm lists. The company's technology stack is built around the third-party Karthago property management platform, supplemented by a newly launched client-facing portal (karthago.VISION, 2025) that provides 24/7 secure document access, online voting on WEG resolutions, digital invoice verification, and damage reporting.

The firm serves a horizontal mix of regional customers across NRW: apartment owner communities (WEG) requiring ongoing financial and administrative management; private landlords of rental portfolios; property sellers and buyers in residential and commercial segments; landowners with parcels suitable for barrier-free development; and a defined Best-Ager/senior buyer persona seeking accessible housing. Representative project work includes the 43-unit barrier-free DU Village development in Duisburg-Buchholz (completed 2019), the 6-unit MOOSHEIDE development in Willich (2018), and commercial leases including a 2,000 m² office rented to a global elevator company in Erkrath.

Haus&Haus combines direct sales (office-based in Hilden, phone, email) with community-led and event-driven go-to-market motions: active participation in BNI Chapter Oboe Hilden generates referral flow; an explicit curated network of 12+ vetted trade and advisory partners (insurance, plumbing, kitchen, roofing, electrical, legal, solar) reinforces both quality of service and cross-referrals; and dedicated project microsites (with reported traffic of 35,000+ page views for DU Village and 18,000+ for MOOSHEIDE) drive pipeline for development sales. Reported outcomes include properties sold at 30% above market value. The firm is a member of the Bundesverband für die Immobilienwirtschaft (bvfi) and reports current operating activity with no funding events, M&A, or leadership transitions disclosed.

Expansion highlights5 records

Broad incumbents

• Engel & Völkers: Global German-headquartered real estate brokerage and franchise operator offering residential and commercial sales, valuation, and project marketing. Directly comparable in that they cover brokerage, valuation, and project marketing, though at significantly larger scale and with international reach.
• Interhyp: Germany's largest independent mortgage broker, arranging construction financing and real estate loans with all major German lenders. Comparable in the financing-arrangement line that Haus&Haus also offers, though at much greater scale and as Interhyp's core business.

Direct peers

• VON POLL Immobilien: German full-service real estate firm specializing in premium residential brokerage, property management, financing, and valuation. Closely comparable business model to Haus&Haus — bundling sales, Verwaltung, financing and Wertermittlung — though operating at a national/international franchise scale.
• Dr. Klein: German full-service real estate services firm offering brokerage, financing consultation, and property management. Comparable to Haus&Haus across the same multi-line service stack (Verkauf, Finanzierung, Verwaltung), with broader regional presence across Germany.
• PlanetHome: German full-service real estate services provider covering brokerage, financing arrangement (via interhyp/planetHome partners), and property management. Comparable to Haus&Haus in bundling Verkauf, Finanzierung and Verwaltung services, with broader geographic coverage.

Emerging players

• Sprengnetter Real Estate: German real estate valuation specialist offering certified property valuations and related software/training. Comparable in the IHK-anchored Wertermittlung line that Haus&Haus provides through its certified valuer, with focus on residential and commercial valuations.
• McMakler: Digital-first German real estate brokerage offering flat-fee residential sales with proprietary technology and a hybrid agent network. Comparable as a brokerage competitor targeting similar private sellers and buyers in Germany, but with a tech-centric model that contrasts with Haus&Haus's relationship-led approach.
• Wertfaktor: German real estate investment and management platform offering property valuation, sale, and management services to private investors. Comparable as a similarly-positioned full-service broker/manager for residential property owners in Germany, with a more tech-enabled operating model.

Others

• ImmoScout24: Germany's leading online property marketplace for residential and commercial real estate. Comparable as a primary listing portal used by Haus&Haus for property marketing and as the dominant marketplace shaping brokerage distribution in Germany.
• Immowelt: One of Germany's largest online property portals for listing and searching residential real estate. Comparable as a distribution channel used by Haus&Haus to market listings, and as an indirect competitor via its lead-generation business model.
