Glaxo Smithkline is one of the world’s largest pharmaceutical businesses with its headquarters located in west London. At about one million square feet, this development was completed 30 months ahead of schedule, saving £60m and set new standards for construction delivery, safety and innovation.

The basement is completely membrane-free!
