The large office project will rise to 21 storeys offering almost 800,000 sq ft of space. Designed by Rogers Stirk Harbour + Partners, building S4 in Zone 2 of the development plan will cost an estimated £250m to build.

The construction arm of Lendlease will deliver the project, which is nearly the size of the combined two earlier buildings for Transport for London and the Financial Conduct Authority.

Ben O’Rourke, Lendlease’s managing director of International Quarter London, said: “This building reflects International Quarter London’s focus on creating a pioneering workplace for progressive businesses, placing culture, health and wellbeing at its heart.

 “The flexible design will allow it to be occupied by single or multiple tenants, and includes a number of technological innovations which are firsts in the UK on this scale.

“For example, it will feature an intelligent closed-cavity façade which tracks the sun with dynamic shading and a supply of 100% fresh air throughout the building.”

The Carpenter Square elevation will offer six large garden balconies

Building S4 is one of several commercial office buildings planned for the IQL south site over the next few years.
