Deansgate Square

The four Towers that make up the Deansgate Square development provide a land mark at the end of Manchester’s Deansgate. The site is bounded by the River Medlock, and flooding constraints played an important part in setting the levels for the site. The towers sit on a two/three storey basement that works with the levels of the adjacent Owen St. To minimise excavation levels for the foundation design the large raft foundation to each tower sits between the two lowest basement levels. This improves the basement wall design by keeping a relatively constant excavation depth in front of the wall. The Towers vary in height from 65 to 37 storeys. A detailed wind tunnel study, with elements of phasing to model the phased construction, were carried out by a UK specialist. Whilst visually similar each tower has a rotated floor plate with Towers A and C, and B and D being similar plan. The frame is in-situ concrete with high strength concrete adopted for the external columns.
