Our sustainable design centred around retaining the original four-storey structure and adding a one storey extension to create 25,000 sqft of quality workspace. We introduced full height glazing and balconies to the existing facade, (saving 39% embodied carbon, equivalent to 59 tonnes of concrete), and created a new double height reception. We invested in extensive landscaping for the wellbeing of employees and to increase biodiversity in the local area.
Constructed within UKGBC’s net zero carbon framework, we worked to exceed LETI’s pioneer standards. The exemplary completed redevelopment targets BREEAM Outstanding, WELL Platinum certification, Nabers 5 star rating and WiredScore Gold.
We followed circular economy principles by re-using materials, diverting 99% site waste from landfill and re-using steelwork from other developments on the client’s estate. Where re-use wasn’t possible, we specified the most sustainable materials possible, including CLT floor slabs in the new extension, cork and envirograph paint.
In addition to radically reducing upfront carbon emissions, our passive design strategy included exposing concrete slabs for improved thermal mass. The net zero carbon all-electric clean energy scheme is enhanced through mixed mode ventilation. We developed on-site renewable energy generation and blue roofs as part of a sustainable urban drainage system. The new redevelopment surpasses best practice and saves an impressive 69% operational carbon compared to a traditional office building.
“Our redevelopment focuses on the comfort and wellbeing of everyone using the space. From creating connections to nature in a city centre to improved natural light and views. In the low VOC environment, we greatly improved connectivity and employee facilities.”
