Derwent London has planning permission for a 285,000 sq ft mixed-use scheme at Tottenham Court Road station. This includes 209,000 sq ft of offices, 36,000 sq ft of retail, a 40,000 sq ft theatre and new public realm. With the 2018 arrival of Crossrail, this major new transport interchange is providing a much needed regeneration boost to the area. In July 2015, Derwent London signed an agreement with Crossrail to re-acquire the site on a new 150-year lease upon completion of the station works in late 2017. The site is due to be handed back to Derwent London later this year and work would commence in H2 2018 with completion in late 2020 to early 2021.
