20 Fenchurch St - the Walkie Talkie

Bespoke Ecoplus concrete mix

A development right in the heart of London is 20 Fenchurch Street, otherwise known as the ‘Walkie Talkie’ and the ‘Pint’ because of its bulbous top. The top heavy massing of this new iconic tower serves to hold a publicly accessible sky garden, making it London’s highest public park.

The building stands approximately 177m high, with 38 floors, including over 60,400m2 of office space together with an additional allowance for retail use.

Providing sustainability and durability

This building was designed to achieve a BREEAM ‘excellent’ environment performance rating. The use of EcoPlus concrete played a big part in helping achieve this through the correct selection of its constituent parts.

The cementitious component of concrete represents most of the embodied carbon dioxide. Hanson supplied the building with a high strength bespoke EcoPlus concrete mix containing up to 50% Regen as a cement substitute, thus significantly reducing the embodied carbon dioxide of the concrete mix. Regen generates very low CO2 emissions, as is a post-industrial by-product.
