This sustainable retrofit will see the redevelopment of a 20th century building, originally built in 1910, transformed into 100,000 sq ft of flexible high-end office space at the heart of London between Holborn and Fleet Street. Work includes the demolition of the existing top floor and the incorporation of two new floors and a roof terrace, utilising the lightweight and sustainable benefits of cross laminated timber.
Another addition to our growing portfolio of redevelopment projects, 5 Chancery Lane will see BKHS complete significant restrengthening work to the existing atrium structure and deliver a new vertical extension utilising a hybrid timber and steel solution.
BKHS will infill the existing atrium, from sub-basement to level four, with new levels of structural steelwork – manufactured from our state-of-the-art facility – and metal decking. A hybrid solution, comprising complex curved glulam perimeter beams and structural steelwork, will then create three new storeys crowned with a Cross Laminated Timber box to the eighth floor.
Our team of structural engineers will draw on our extensive experience with timber to complete innovative member and connection design for the structural timber elements, showcasing our expertise with this type of this complex retrofit and extension.
5 Chancery Lane illustrates how a building can adhere to both new net zero regulations and occupier demands, through sustainable retrofit.To keep with the current demands and changing nature of the commercial sector, the redevelopment has been strategically designed to reduce operational carbon and water consumption. Aiming to retain and reuse 86% of the original building, with Upfront Embodied Carbon costs 33% lower than the GLA’s aspirational benchmark, the project is targeting BREAM Excellent and uses a circular approach to retrofit.
