Google will submit revised plans for its new £1B U.K. headquarters at Kings Cross next month, according to Building Design.

BIG and Heatherwick Studio, which also designed the company’s Mountain View, California, headquarters in the U.S., were hired last year to take over the project after the tech giant broke with AHMM, which worked on the scheme for nearly four years. The refreshed plans for the 10-storey building focus on the interior rather than the exterior, but keeps some aspects from AHMM’s original 2013 design.

Google also recently struck a £650M deal with Lendlease to build its new London headquarters. Google’s EMEA director of real estate and construction, Joe Borrett, said the companies share a desire to challenge industry norms, focus on innovation and have a highly collaborative approach. The new building will house up to 4,000 employees.
