Mertins Landschaftsarchitektur

What Mertins Landschaftsarchitektur does

Mertins Landschaftsarchitektur is a small, owner-managed landscape architecture practice based in Hamburg, Germany, founded by Reiner Mertins around 2000 and operating under his continued direction as Geschäftsführer. The firm provides end-to-end landscape architecture services covering all HOAI Leistungsphasen 1–5, from initial sketch through preliminary design, final design, tendering preparation, and construction supervision, for outdoor facilities including gardens, parks, school grounds, kindergartens, residential complexes, commercial campuses, and public squares. Core project categories on its website span Wohnen, Verwaltung, Schule, Kita, Park, Garten, Verkehr, and Sonderbau, with notable completed engagements including the Beiersdorf Campus (2023), Sophie-Barat-Schule (2025), and the DGNB Gold-certified Eidelstedter Höfe residential quarter (2025).

The firm delivers projects using industry-standard design and visualization software (AutoCAD, Adobe Creative Suite, SketchUp, Lumion) rather than proprietary platforms, and there is no disclosed AI, API, or SDK offering. Its revenue model is professional services, project-based and quote-based, with no publicly disclosed pricing. Go-to-market relies on direct client engagement, public sector procurement, and referrals via chamber and association memberships (Hamburgische Architektenkammer, BDLA), supplemented by organic social channels (LinkedIn, Instagram, XING), an active project portfolio on its website, and earned media through recurring inclusions in the Architektur in Hamburg yearbooks and an international LAK Korea magazine feature. Operations are concentrated in Hamburg and adjacent areas of Schleswig-Holstein and Lower Saxony, with a 2025 Bürogemeinschaft partnership with Kontor Freiraumplanung extending effective delivery capacity.
