Lohaus Carl Köhlmos Landschaftsarchitekten Stadtplaner

What Lohaus Carl Köhlmos Landschaftsarchitekten Stadtplaner does

Lohaus Carl Köhlmos Landschaftsarchitekten Stadtplaner is a German landscape architecture and urban planning partnership operating as a PartGmbB (Partnership with limited professional liability) under the registered style LOHAUS + CARL GmbH Landschaftsarchitektur + Stadtplaner. The firm was reorganized under its current name and legal structure in May 2019 (with operating history traceable to 1996) and is led by Prof. Irene Lohaus and partner Peter Carl from offices in Hannover and Dresden with a total headcount of approximately eight staff.

The firm's core offering consists of professional design and consulting services for public open spaces, including urban parks, public squares, pedestrian and cyclist bridges, school and campus landscapes, residential quarter planning, and flood-management green infrastructure, with explicit specialization in barrier-free design, climate-resilient park landscapes, and integrated green infrastructure. All work is delivered as project-based professional services; the firm operates no software or product platform. Capabilities are demonstrated through award-winning built work including Westpark Augsburg (Deutscher Landschaftsarchitekturpreis 2021, European Garden Award 2023), Kirchplatz St. Viktor in Dülmen (nrw.landschaftsarchitektur.preis 2024), Dalkebrücke in Gütersloh (LIT Lighting Design Award 2025), and the just-opened Glashüttenpark Köln-Porz and Park in den Wupperauen Hückeswagen.

The business model is exclusively public-sector and project-based. Revenue is generated through German public procurement channels — realization competitions (Realisierungswettbewerb), invitation-only competitions (Einladungswettbewerb), VgV-Verhandlungsverfahren, and parallel commissioning (Parallelbeauftragung) — with fees typically structured under the HOAI framework. The customer base is entirely German municipal and governmental entities (including Gütersloh, Augsburg, Hannover, Dülmen, Ennigerloh, Hückeswagen, Flöha, Köln-Porz, Garbsen, Emden, Verden). Go-to-market relies on competition success and industry recognition rather than outbound sales, with marketing channels limited to industry awards, the Competitionline platform, and active participation in bdla association events.
