What Leonwohlhagen does

léonwohlhage Gesellschaft von Architekten mbH is a Berlin-based architecture firm founded in 1987 by Hilde Léon and Konrad Wohlhage, operating today as an independent practice under the umbrella of DGI Bauwerk Gesellschaft von Architekten mbH following a 2022 strategic partnership. The firm delivers full architectural services across all HOAI work phases (Leistungsphasen 1–9) — from concept and competition design through general planning (Generalplanung), space and cost planning (Raumbuch, Kostenplanung), scheduling (Termin- und Ablaufplanung), and construction-phase quality assurance — for public and private clients across Germany.

The firm's project portfolio spans educational facilities (Europäische Schule München, Kita Wallenbergstraße Berlin, Humboldt Grundschule Mannheim, Gymnasium Karlsfeld), office and government buildings (Büro- und Geschäftshaus Leipziger Platz Berlin, Büro- und Geschäftshaus LIST Hannover, Justizzentrum Osnabrück, BImA Rostock), and large urban residential and mixed-use quarters (Weserhöfe Bremen 28,200 m², Südliches Oberwiesenfeld München 67,251 m², Tabakquartier Woltmershausen Bremen). Beyond services, the firm has co-developed proprietary design products — Kanto floor lamp, Instant Space room divider (iF Gold 2006), and Visio acoustic ceiling light (Red Dot 1997) — with manufacturing partners.

Revenue is generated through project-based professional services fees, acquired primarily via architectural design competitions in which the firm has secured numerous first prizes since 1994. The combined léonwohlhage/DGI Bauwerk planning team comprises 70+ qualified professionals under unified leadership (Prof. Hilde Léon, Managing Director, alongside Associates Peter Czekay, Meltem Tekin, and Reinhard Spät), all operating from a consolidated Berlin office at Schillstraße 9 since March 2024.
