We are a secure, sustainable practice offering talented, committed people the opportunity to work on challenging projects in a supportive, creative and rewarding environment. We endeavour to create a virtuous cycle where high calibre people are attracted by challenging projects and our clients, in turn, are attracted to the quality of design and service provided by our teams.

Wilco Stekkinger


Wilco first joined Holder Mathias as a student becoming one of the practices’ most talented designers, firstly as part of the team on projects such as Altolusso and Atrium and then leading on the critically acclaimed re-modelling of Gwyn Hall and the new Admiral Insurance offices in Newport. Wilco’s enthusiasm is infectious and is felt throughout the studios.
