What IWP Hohental Plan- und Generalbau GmbH does

IWP Hohental Plan- und Generalbau GmbH, trading as Hohental Gruppe, is a privately-held German construction and real-estate development company headquartered in Berlin with a regional office in Hamm (North Rhine-Westphalia). Founded in its current legal form in 2019 and tracing its corporate history to a 2006 real-estate generalist, the group operates as an integrated general contractor and lead consultant serving public and municipal housing companies, institutional investors, and select public-sector clients (schools, nurseries, administrative buildings) across Berlin, NRW, Saxony-Anhalt and Lower Saxony. Named customers include HOWOGE, WBM, Berlinovo, GESOBAU, Stadt und Land, Wohnstätte Krefeld, Becker & Kries, Sparkasse Hamm, and organizations such as the German Red Cross and Malteser.

The company's product portfolio comprises three core service lines: Neubau (new-build construction) as general contractor and lead consultant under fixed-price turn-key contracts, Revitalisierung (ESG-compliant energetic modernization of occupied existing properties), and Projektentwicklung (property development from concept through handover with forward-deal options for joint-venture partners). A complementary Leistungsvorsprung capability set bundles temporary property management during refurbishment, municipal-procurement expertise, and early-phase project integration. Notable proprietary elements include the Hohental Refurbishment Concept - a 5-phase methodology spanning roof, façade, heat generation (air-to-water heat pump), basement ceiling, floor plan optimization, sanitary, electrical, triple-glazed windows and EV-charging infrastructure - and a serial construction methodology aligned with the GdW Rahmenvereinbarung 2.0 framework agreement that enables pre-qualified procurement by municipal housing companies. The group's published track record covers more than 10,000 residential units planned/realized, 410,000+ m² of gross floor area in Berlin, a 20,000-unit acquisition/development/refurbishment/management portfolio across four German states, and 20+ new school buildings.

Revenue is generated primarily through fixed-price turn-key construction contracts (recognized on project completion), professional-service fees for lead consultancy, transaction fees on property development including forward-deal structures, and managed-service fees for asset and property management. Distribution is enterprise field-sales driven, supported by industry-conference participation (PLENBA), PR through an external press office, content marketing via LinkedIn, Instagram, Facebook and a company magazine ("Fundamental"), and a regional network of approximately 200 suppliers, service providers and sub-contractors. Pricing is project-specific and quote-based with no public price list. The company is founder-owned by Frank Illmann (Dipl.-Ök.), with a four-principal management team (Jens Wadle, Hanna Scharmach, Christian Marschner, Dr. Christoph Schmid) carrying 18-30+ years of relevant industry experience, and reports no external private-equity, venture-capital or institutional-investor ownership.
