Architekturbüro Köhler

What Architekturbüro Köhler does

Architekturbüro Köhler is a sole-proprietorship architecture practice founded in 2017 and operated by Hayung Köhler from Roge/Sierksdorf in Schleswig-Holstein, Germany. The firm delivers the full HOAI Leistungsphasen 1–9 service spectrum — from basic assessment and conceptual design through detailed design, tendering, construction supervision, and project closeout — for residential, commercial, public-sector, and renovation commissions. Its client base spans regional developer clients (WERTPLAN, UPESTATE), a long-standing theme-park operator (HANSA-PARK), retail anchors (Kaufhaus Stolz), and municipal/civic engagements (Stadtwerke Neustadt, HMD Stahl-Metall-Design / SIG Holost on the Speichertürme Areal).

The business model is straightforward professional-services fee billing, primarily under the German HOAI fee ordinance, against project-based mandates. The practice operates with a small team of approximately 7 FTE according to firmographics, expanding to roughly 10–11 contributors when including a dual student (Laura Möller, Hochschule Mainz), a project assistant, and supporting family members. Geographic scope is concentrated on the Baltic Sea coast of Ostholstein — Sierksdorf, Neustadt, Großenbrode, Dahme, and Fehmarn — with notable engagements such as the Kärnan roller coaster at HANSA-PARK, the Energiespeicher Neustadt seawater heat-pump storage facility, and grain-silo heritage conversions. The recent pipeline (Townhouses Dahme, Einfamilienhaus Stockelsdorf in planning) and the launch of an Instagram channel indicate modest commercial expansion but no structural break from the regional boutique model.

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• KSP Architekten: Major German architecture firm covering office, public, and commercial buildings with international footprint. Overlaps with Köhler on commercial (Gewerbebauten) and public building (Öffentliche Bauten) categories at much greater scale.
• Heinle, Wischer und Partner: Long-established German architecture and engineering firm working across residential, commercial, and public buildings. Comparable on full-service architecture-and-engineering delivery and on public-sector commissions like those Köhler performs for Stadt Neustadt.
• Barkow Leibinger: Berlin/Hamburg-based architecture firm recognized for innovative cultural, commercial, and specialty structures. Comparable on bespoke, design-led commercial and public projects, including complex specialty buildings similar to Köhler's HANSA-PARK attraction work.
• HPP Architekten: Established German architecture firm with strengths in commercial, retail, public, and renovation projects across Europe. Comparable on project categories (retail centers like Kaufhaus Stolz, public buildings, commercial architecture) but operates at much greater scale than Köhler.
• Max Dudler Architekten: German architecture practice with a portfolio spanning public, cultural, residential, and commercial buildings. Overlaps with Köhler on high-quality residential, public, and renovation projects, though operating at city and national scale.
• gmp Architekten: One of Germany's largest architecture practices with broad portfolios in stadiums, transport, public, and commercial buildings. A broader incumbent whose general architectural service offering overlaps with Köhler's full HOAI LP 1-9 scope, though gmp operates at national and international scale rather than regional Holstein focus.
• Hascher Jehle Architektur: Berlin-based German architecture firm active in commercial, retail, public, and adaptive reuse projects. Directly comparable on heritage renovation (Bauen im Bestand) and commercial building categories Köhler serves, but at significantly larger scale.
• Staab Architekten: German architecture practice with portfolio in cultural, public, and residential buildings. Overlaps with Köhler on public buildings and high-quality residential work, with comparable emphasis on detailing and material quality.
