This month’s issue presents everything you need to know about the UK’s largest architecture practices, including fee and practice data so you can compare business performance and benchmark your own practice.

Following a destabilising few years, a theme of renewed optimism runs through the findings, with the total number of architects employed at AJ100 practices having grown for the fourth year running.

It has been 30 years since the first AJ100 was published, and we look back at the seismic changes that have impacted the profession over these decades, from the introduction of digital technology to increased awareness of sustainability in practice.

We also reveal the 12 winners of AJ100 Awards, including Contribution to the Profession honouree David Levitt, who is recognised for his contribution to architecture and housing. Find out which of our six AJ100 Champions has been crowned Practice of the Year, who is leading the way on sustainability, mentoring and communication, and discover emerging talent in our New Talent awards for architectural assistants and new architects.

Elsewhere in the issue there are reviews of Do Ho Suh’s Tate Modern show and multi-sensory installations at the Barbican Centre, while in Opinion Kunle Barker and Matthew Turner reflect on the difficulties of finding jobs in the industry.
