Google headquarters architect Bjarke Ingels Group (BIG) has jumped into the top 50 of the world鈥檚 biggest architects, according to this year鈥檚 World Architecture 100 (WA100).

The US-Danish practice, which along with Thomas Heatherwick formally replaced AHMM on the 拢1bn project last year after the tech giant asked for AHMM鈥檚 consented scheme to be redesigned at the end of 2013, has snuck into the top 50 of this year鈥檚 list at number 49, after making its debut in the WA100 at 89th position last year.

The list, BDOnline鈥檚 annual ranking of the world鈥檚 biggest architects, is based on the number of architects employed rather than turnover. BIG, which is also behind a public square at the Battersea Power Station redevelopment and whose founder Bjarke Ingels was asked to draw up plans for last year鈥檚 Serpentine Pavilion, employs 224 architects and had a fee income of between $40m and $49m this year.

It has three main offices 鈥 New York, Copenhagen and a London office at Finsbury Avenue in the City close to Fosters鈥 recently opened Bloomberg building 鈥 and earlier this year submitted plans for the 81,000m2 Google building, which will become home to 4,000 staff.

Fosters remains the UK鈥檚 largest practice, with 642 architects and a fee income of $180m to $189m.

Fosters is one of 13 UK practices on the WA100 list. Others include 100 Bishopsgate tower architect Allies and Morrison, the country鈥檚 only listed architect Aukett Swanke, and the practice behind Willmott Dixon鈥檚 overhaul of Alexandra Palace in north London, Feilden Clegg Bradley Studios.

And Ken Shuttleworth鈥檚 practice Make enters the list for the first time in joint 100th place, with 86 architects and a fee income between $20m and $29m.

US practice Gensler remains the biggest practice in the world, with fees now more than double that of the next best rival.

The firm, which employs 2,560 architects and was behind the fit-out of software giant Adobe鈥檚 new London offices at the White Collar Factory on Old Street, had a fee income of $1bn to $1.5bn 鈥 head and shoulders above second-placed Nikken Sekkei, with the Japanese firm posting $500m to $599m.

The top three remains unchanged, with US giant Aecom staying in third place, having just over 1,600 architects and a fee income between $600m and $699m 鈥 although on fee income for architectural services alone, the firm is the biggest practice with fees of $596m compared with Gensler鈥檚 $559m.

But Gensler outstripped all its rivals on interior design with an income of $450m, five times that of Aecom in second place.
