Top-down construction adopted to accelerate completion of ten-storey commercial phase

PJCE re-engineered the original planning scheme to provide a cost-efficient design. The use of top-down construction for the long span steel office building and a bottom-up sequence for the residential towers not only reduces the build programme, but also minimises the requirement for extensive temporary works.

The fifteen and nineteen storey residential blocks comprise in-situ reinforced concrete slabs supported on a combination of regular and blade columns and a central core. A transfer deck at ground floor level allows a change in grid, which maximises car parking within the basement. The double basement also provides retail, cultural and plant space. At ground floor level the blocks are linked by a reception area and landscaped podium.


The sculptural curved façade comprises 900mm wide faceted triple-glazed units and required a high level of coordination with the structural design team. In-ground drainage, SuDS and civil designs, including Section 278, were coordinated and designed by PJCE.
