The Architects' Journal (AJ) have revealed the results of their fourth AJ120 award, an annual survey which ranks the largest and wealthiest practices based in the UK. Partially calculated on the number of ARB-registered (or equivalent) fully qualified architects in employment, the AJ have announced that London based Foster + Partners have topped the 2015 table. Describing the 48 year old practice as an "international powerhouse," employing 312 architects (out of their 1,066 employees worldwide), the survey also shows that "the £185million fees billed by the practice’s architects – up a huge £45 million from last year – made up 38% of the combined total of all of the companies in the Top 10." The survey saw BDP ranked second, while AHMM came in third.
