Developers Stanhope and Mitsui Fudosan plan to build three office blocks at White City Place on the 17-acre vacant site adjacent to the Imperial College campus.

The landmark office complex plan marks the third phase of development at White City and includes a major stepped block known as Gateway East rising to 21 storeys.

It will be accompanied by a second big block rising to 11 storeys next to the third smaller building up to four floors high.

Contractor Lendlease has drawn up the construction plan for the developers with construction now expected to start shortly.

Architect Allies and Morrison designed the project, with AKTII on board as structural engineer and Sweco acting as services engineer.

The new Gateway development will include extensive public realm improvements, which will link with the landscaping works underway at White City Place including North Avenue with new trees, raised gardens, lawns and the creation of a Central Square.

The three Gateway buildings will complement the six existing buildings at White City Place. These include MediaWorks and WestWorks which have been refurbished, Garden House which has been let to the Royal College of Art. The other three – Broadcast Centre, Energy Centre and Lighthouse buildings – are pre-let to the BBC.

The Gateway development will complete White City Place, which will total over 2 m sq ft.
