Core offering

Korteknie Stuhlmacher Architecten is an architecture studio providing full architectural design services — from feasibility studies through schematic design, design development, construction documents, and construction administration — for schools, healthcare facilities, cultural and public buildings, private residences, and the adaptive reuse of historic and monumental structures. The firm has particular specializations in mass timber/CLT construction and the transformation of existing buildings (churches, monasteries, schools, hospitals) into contemporary public functions, with commissions acquired primarily through architectural competitions and direct client appointments in the Netherlands and Belgium.

Product overview

The studio also undertakes Competition and Research projects. Their portfolio spans public buildings (libraries, schools, community centers) and private residences, with notable projects including Campus Cadix (inner-city school campus in Antwerp, ARC22 winner), Stadsbibliotheek Het Predikheren Mechelen (ARC19 Interior Award winner), De Predikherenkerk (converted baroque church into performing arts venue), Sint-Martinuskerk Burcht (church conversion to community center), and various residential projects (Utrecht house, Uitdam house, Goeree country house).
