Havelock BREEAM Outstanding

31.01.2025

We are delighted to announce that Havelock is the first full building retrofit project in the North of England to have been certified as BREEAM Outstanding upon completion. 

Achieving this certification is a remarkable achievement and will ensure resource efficiency and lower maintenance and energy costs over the building’s lifespan.

Situated at 70 Great Bridgewater Street in Manchester, Havelock is a comprehensive retrofit of an existing office building formerly known as Evershed House. In total 10,290sqm of office accommodation is provided across 8 levels, two of which were added to the original concrete frame helping to increase overall net-internal area by 3,700sqm. The wholescale internal refurbishment includes the provision of a reception and lobby, lounge areas, cycle storage, changing rooms, showers, and a wellness studio. Each level has access to outdoor terraces, projecting from the steel structure at opposing corners of the floorplate.

The deep retrofit strategy, included the installation of an entirely new façade system, developed as the optimum solution through the use of a whole-life carbon option appraisal, ensuring that, through the utilisation of the existing structure, the project retained 2,000 CO2e of embodied carbon, the equivalent of planting 10,250 trees. It has also received a NABERS 5 star rating and has been used in the UK Green Building Council document ‘Building the Case for Net Zero : Retrofitting Office Buildings’.
