What hks architekten does

hks architekten is a German architecture and planning firm headquartered in Aachen, founded in 1981 as architekturwerkstatt ac and operating today as hks architekten GmbH across three offices in Aachen, Bonn, and Erfurt. The firm employs more than 95 architects, urban planners, engineers, and technical/commercial staff, and is led by seven managing shareholders, all of whom are registered BDA architects. Its primary customers are German public-sector entities — federal ministries and agencies (Bund), state governments (Länder), counties (Kreise), municipalities (Kommunen), and universities — with a secondary private developer and corporate client base.

The firm's core offerings are BIM-supported planning (implemented since 2014), a patented Modular Housing System developed since 2018 in cooperation with ProjektBauart (Patent EP3872279, utility model GM 20 2020 101 074; approximately 370 units realized), and Integrated Project Delivery (IPA) — a collaborative project execution methodology with shared target costs and transparent open-book calculations. Underlying technology includes ArchiCAD-based BIM with interdisciplinary rule-based quality controls, automated clash detection, and Microsoft Teams cloud collaboration. Supplementary services include project development, overall planning (Generalplaner), existing-buildings work, timber construction, and barrier-free design.

hks architekten generates revenue through project-based professional services fees typical of German architecture firms, acquired primarily via participation in public and private architecture competitions (over 150 successes, including 35 first prizes) and direct commissions. The firm holds ISO 9001:2015 certification since 2004 and has been a buildingSMART Deutschland member since February 2022. Distribution is direct to clients with no intermediary channels; marketing relies on competition wins, publications in architectural yearbooks, Tag der Architektur participation, and a project-rich website rather than traditional advertising.
