Allied London and architect Levitt Bernstein have unveiled detailed plans for the refurbishment of Astley & Byrom House, now known as ABC, which could include a cinema alongside nearly 130,000 sq ft of office space.
Allied London bought the offices on the edge of Spinningfields in July last year, and has now submitted a planning application for a comprehensive overhaul and remodelling of the 1960s office blocks.
Internal space at the ground floor level of the adjoining two-storey Cooper House will be reconfigured to provide three retail or commercial units of 12,800 sq ft, 11,200 sq ft, and 600 sq ft. These have been earmarked for a cinema, a gymnasium, and events space.
Meanwhile the office’s floor plates and existing cores will be upgraded to house additional office space: Astley’s office floor plates will be around 6,300 sq ft per floor, while Byrom’s will be around 8,000 sq ft per floor.
Rooftop extensions will add a combined 8,000 sq ft to the development, the largest of which will be on Astley House at 3,600 sq ft.
An amenity and events space will be created on the roof that joins both buildings, along with a communal terrace for office tenants.
The designs show the removal of the buildings’ façade facing Quay Street, replaced with anodized metal with a black finish and glazing, while parts of the original façade will be refurbished and cleaned.
Entrances to Astley & Byrom House will be significantly remodelled as part of the plans.
Overall, the development will provide 181,000 sq ft of office and commercial space; 82,900 sq ft in Astley; 46,000 sq ft in Byrom; and 52,200 sq ft in Cooper.
Both buildings were originally designed by Leach Rhodes Walker. Astley House was built in 1959, and Byrom House was completed in 1965.
Alongside Levitt Bernstein, the professional team includes OBI Property as project manager; Deloitte as planner; Curtins as structural engineer; REDS as mechanical engineer; Crofts as transport planner; and Sandy Brown as acoustic consultant.
The buildings’ former owner, West Midlands Pension Fund, advised by CBRE Global Investors, gained planning permission in 2015 for the redevelopment of the site, with a scheme that would involve the demolition of both buildings, replacing them with three blocks staggered in height at between six and 14 storeys.
Stride Treglown was the architect for the proposals, but these were never progressed.
Allied London declined to comment.
