Key Details

Overview

458 Oxford Street is the redevelopment of the Marks & Spencer Marble Arch store building in London W1.

The proposed mixed-use building will include flexible retail space accommodating a new full-line Marks & Spencer Marble Arch store, best-in-class Prime Grade A sustainable offices and a world-class public realm.

Plans include

- A new building of ground plus 9 storeys including plant. The existing building is ground plus 5 storeys plus plant.
- 90,000 square feet of retail space at the lower ground floor, ground floor, and part of the first floor
- More than 300,000 square feet of Prime Grade A office accommodation.

Sustainability

Reduction of both operational and embodied carbon. The team is undertaking Whole Life Carbon Assessment to identify and maximise opportunities for carbon reduction, following the UK Green Building Council’s Net Zero Carbon Framework. Examples of opportunities being explored include low carbon materials for floor slabs and maximising the performance of the façade to reduce operational energy demand.

The target for the project is to achieve BREEAM Outstanding, WELL Platinum, and WIRED Platinum accreditation for the office space.
