Justus Grosse

What Justus Grosse does

Justus Grosse is a Bremen-based, family-owned (Linnemann family) real estate development and management group founded in 1946 and operating through Linnemann Immobilien Holding GmbH. The company delivers the full real estate lifecycle across Northern Germany: project development of residential, commercial, hotel, and mixed-use properties; long-term property management for owned and third-party assets; third-party brokerage via Justus Grosse Services GmbH (founded July 2024); and, since January 2026, sustainable energy infrastructure via Justus Grosse Energie GmbH covering PV systems, heat solutions, and EV charging. Its scale is anchored by the ~700M EUR TABAKQUARTIER development in Bremen-Woltmershausen, a 20-hectare brownfield conversion delivering roughly 1,000 apartments and 120,000 sqm of commercial space, alongside parallel pipeline projects such as Alte Süßwarenfabrik (~250M EUR), Lighthouse (Bremen's first mass-timber office, ~15M EUR), TQ Living, TQ Studios, ALVA, PEER, LUX, and the GEWOBA-co-developed Fleethäuser (126 subsidized apartments).

Technology centers on sustainability engineering rather than digital platforms: regenerative district heating sourced from waste-heat recovery via heat pumps, building-integrated PV with direct electricity sales to occupants, scalable EV charging infrastructure, DGNB Gold pre-certified quarter development, EH 40 energy-efficient new builds, and mass-timber construction (Holzmassivbauweise). Ancillary participations include Linnemann Hotel Holding GmbH (hospitality) and Überseestadt Entwicklungs GmbH (urban development). Underwriting property is published (subsidized rentals at 6.80 EUR cold/sqm via GEWOBA), but transactional pricing for sales, rentals, and brokerage is negotiated individually.

Revenue flows from one-time project sales (developer forward deals to institutional buyers and end users), recurring property and SEV management fees, transactional brokerage commissions, and managed services from the new energy business. The customer mix spans housing associations (GEWOBA, LEG), institutional investors (Columbia Threadneedle, BMO, HanseMerkur), corporate tenants (JDE Peet's DACH HQ, Siemens, CMA CGM, DMK, IGEL), public-sector tenants (Dataport, Senator für Finanzen Bremen), and nonprofits (Johanniter-Unfall-Hilfe, Bremer Philharmoniker). Management is led by managing partners Marcel Linnemann, Julian Linnemann, and Burkhard Bojazian alongside Sven Pluschke, Christian Rau, Simon A. Rott, and Paul Schulze-Smidt, with the company celebrating its 80th anniversary in 2026.
