AJ100 Awards 2025
This year marked the 30th anniversary of the AJ100 survey, the definitive annual record of the UK’s largest architecture practices, measured by the number of architects employed in the UK.
The accompanying AJ100 Awards programme celebrated the achievements of these firms.
We showcased emerging stars in our New Talent category, as well as those leading the way on sustainability, mentoring, and employment policies. We also selected a new cohort of Champions, a group of practices driving positive change in the profession.
AJ100 practices were invited to attend the AJ100 Gala Lunch on 20 June, when the winners of the 2025 AJ100 awards were revealed. This celebratory event returned to the Honourable Artillery Company in London.
