Sloane Street


Project Description

Client: Cadogan Estates
Main Contractor: Mace
Architect: Stiff & Trevellion
Engineer: AKT II

Located in one of Chelsea’s best known locations, 127-135 Sloane Street is located within meters of Sloane Square and The Kings Road, requiring a need for extreme levels of consideration for the residents surrounding the development. Apart from the ongoing construction activity, there had been previous buildings on the site requiring demolishing prior to any ground works taking place.

The new six-storey building is for mixed use for the Cadogan Estate comprising retail at ground floor level, and five levels of offices above, the building has a gross internal area of 12,702m². An attractive recessed courtyard to the rear of the building will open onto the lower ground floor retail frontages and a restaurant. A selection of small, independent retail units are also on the Pavilion Road side of the development.

Started in January 2013 this was Morrisroe’s first project for Mace, and comprises of a substantial substructure package, including bulk excavation of over 20,000m³. Morrisroe is also undertaking the temporary supports for the two-level basement, the waterproof reinforced concrete raft structure and lining walls, the precast reinforced concrete ground floor structure, two non-reinforced concrete cores, and structural topping to the steel frame.

In such a high profile, heavily populated area, the project presents a range of challenges, orientating around safety and logistics as demonstrated by the precise management required to facilitate the bulk excavation. This one task alone required the safe orchestration of over 100 HGV muck removal movements during daylight hours without disrupting traffic or disturbing residents. Morrisroe constructed the main reinforced concrete core using our successful jumpform technology, which was a large part of the project.
