The sensitive and sustainable refurbishment and extension of the existing structure of Millennium Bridge House to create a flagship office building in the City of London. The building is ‘all electric’ with gas on site. It incorporates thermal storage and heat-pumps to recover heat which would typically be rejected to atmosphere reducing the peak demand and carbon emissions. Circular economy principles are embedded in the design; reusing the existing structural frame, reduces the need for new materials and excavations. The internal spaces are flexible and adaptable. The facades comprise of a unitised system manufactured off-site reducing construction waste. The building’s landscaped roof terrace, which is accessible to the public, makes a significant positive contribution to the ecological value and biodiversity of the area.
