It’s the thing of dreams, but it has the price tag to match: this raw space at the Barbican is a one-off opportunity to create a brand new home within the existing Grade II-listed modernist estate.

For sale via The Modern House for £4m, The Void is a disused space at the base of Barbican’s Cromwell tower. Plans by 6a Architects and Sanchez Benton reimagine the 30ft tall, 65 ft long space as a neo-brutalist home with living rooms stacked on one side of the quadruple height void, like shelves.

Planning approval has already been achieved for the 3,100 sq ft London property. CGI renders reveal a series of elegant galleries open to a soaring vertical void that floods interior levels with light. The steel and glass skeleton of the structure is exposed, with textures coming via cast concrete, timber and a simple steel staircase that ascends the height of the residence.

Living spaces are ‘hidden’ on the lower levels, with bedrooms and private spaces secluded within the span of the upper floors. The plans allow for a living room, kitchen and library on the first floor, with access to the mezzanine lobby of Cromwell Tower.

Two bedrooms will occupy the second level, with the main suite spanning the entire third floor.

Cromwell is part of a triplet of towers within the Barbican estate, completed in 1973 at the junction of Beech Street and Silk Street. The brutalist estate was given Grade II listed status in 2001 and ranks among London’s most coveted postcodes.
