Contractor Lendlease is delivering the project on behalf of client Great Portland Estates, to include high-quality retail and office space.
Located on the corner of Oxford Street and Newman Street, the new building will provide retail space on the lower ground, ground and first floors with office accommodation on the upper floors.
The project includes the removal and replacement of a power substation. Demolition works at the site were completed in April 2019 and construction of the lower ground is now underway.
Ground and upper floors will be constructed from structural steel columns and beams with composite steel decking, reinforced concrete slabs and reinforced concrete core walls. A structural steel framed plant gantry will be constructed to the rear of the building.
The façade of the building will consist of unitised curtain walling, with curved glass to the southeast and southwest corner. The shopfronts will use a glazed stick system.
Helen Hare of Great Portland Estates said: "We are delighted to be working with Lendlease again for our ongoing regeneration of the east end of Oxford Street. 70-88 Oxford Street and 1 Newman Street will provide a high-quality retail and commercial offer in an area of the West End that is seeing strong demand for both types of development in advance of the arrival of the Elizabeth line."
The new building has been designed to achieve rigorous environmental standards .
It is scheduled for completion in spring 2021.
