The Post Building

In the heart of Bloomsbury between the British Museum to the north and theatreland to the south, the former Royal Mail Sorting office is being redeveloped into a new mixed-use development set within an enhanced public realm by Gillespies.

Gillespies has designed a roof terrace landscape and a new enhanced public realm for The Post Building, a new commercial-led development that will transform the former Royal Mail Sorting office at 21–31 New Oxford Street.

The public realm proposals integrate the new development into its context and redefine the important pedestrian links and historic routes that already exist. The proposals will reopen the historic Dunn’s Passage, which has been closed to the public for many years. Gillespies’ design places an emphasis on improving the pedestrian experience through re‑paving with high quality materials, de‑cluttering pavement zones, careful placement of street furniture and altering traffic flow to achieve a better balance between pedestrian and vehicular movement.

The roof landscapes draw inspiration from the industrial nature of the site’s former use as a sorting office, and the architectural expression of the proposed building.

There are a number of adjacent improvement schemes proposed for in the coming years and it is envisaged that the public realm delivered through this development will fit seamlessly with these other schemes.
