King's Cross Building B4

Building B4 is one of three new office buildings that’s form a part of the masterplan for King’s Cross Central. The buildings look onto two new public spaces – Pancras Square and the King’s Boulevard. It provides 130,000 sq ft net Grade A office space above retail and restaurant uses. 
The facades are composed from a white precast stone outer masonry layer, behind which sits a fine metal and glass inner layer. As the building rises, the masonry window surrounds become more delicate, whilst the inner glass layer recedes into the building. At the final floor it is completely absent, revealing a glimpse of sky. 
Sustainability has been central to the development of the King’s Cross masterplan and, as such, Building B4 is enabled for a BREEAM 2011 rating of Outstanding.
