WH was born of the meeting of Julien Woycinkiewicz and David Héron.

Numerous years of experience in world famous architecture agencies of international scope have enabled them to develop far reaching projects at various scales.

These acquired abilities make it possible today for WH to adapt to all types of orders, and to treat just as well individual or collective housing projects and public equipment orders.

Numerous clients, contracting authorities and partners have trusted their skills for the designs as well as for the following up either of new buildings or of restorations and improvements of old properties.

Rather than dealing with concepts WH endeavour to build up an architectural choice allowing them to deliver singular building designs in keeping with the principles of efficiency and sincerity.

An open architecture rid of complexes in order to nurture our senses and rediscover poetry in everyday life.
