20 Fenchurch St - Walkie Talkie
A skyscraper 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 160 metre high, with 38 floors. This building achieved a BREEAM “excellent” environment performance rating. BREEAM is the leading environmental assessment method and rating system for buildings.
The use of Hanson’s EcoPlus concrete played a big part in helping achieve this through the correct selection of its constituent parts. 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 it is a post-industrial by-product.
