HYLO is one of the most pioneering tall-building retrofit projects in London. Absorbing the former, mid-rise Finsbury Tower office building within the delivery of a modern, high-rise mixed-use development.

With the primary driver focused on minimising the embodied carbon, the project became a refurbishment and extension adding 13-storeys on top of the existing 16-storey structure.

Considerable planning was required to devise a construction programme that allowed the works to be continuous. The floorplate was split into three main areas and the steelwork was built three floors at a time.
Primary activities involved welding fittings to cast-in plates in the core walls for beam connections, steelwork erection, metal decking installation and on-site painting. These activities continuously rotated throughout the floorplate to meet programme. With the steel frame starting at Level 16, Bourne’s main challenge was dealing with high winds during construction, while maintaining the programme and the tight erection tolerances.
