The Interlock

The transformative effect of creative brickwork.

A modern, five-storey building in London’s Fitzrovia that once paled in comparison to some of its more elegant neighbours is now arguably the street’s most striking resident.

The Interlock is an outstanding example of what is possible when architect and clay brick manufacturer put their heads together.

Forterra’s Technical team worked with architect Bureau de Change, drawing the building’s new façade brick for brick to ensure technical possibility and aesthetic ambitions aligned. It then fell to the team at Forterra’s Cradely Special Bricks facility to design and produce the bricks.

Guided by 1: 1 templates the complex construction took three months to complete, as each of the 5,000 bespoke Etruria Clay Blue bricks was painstakingly laid to form the three-dimensional, interlocking pattern.

We are proud to announce that The Interlock won three awards at the 2019 Brick Awards. The project won the prestigious Architects’ Choice award along with also winning in the Innovation and Small Housing Development categories.

This project is a great example of a collaborative approach with our customers.
