Back to Projects

In 2012 Expedition prepared a Masterplan Feasibility Report for Selfridges that explored redevelopment opportunities across their store in Oxford Street, London. The underlying philosophy of developing designs to respond to and allow the Business to keep the greatest extent of this flagship retail building operational during the works lead to Expedition’s appointment on the Selfridges Duke Street Project in 2013.

The Duke Street Project includes several large scale civil and structural interventions in a highly constrained site, which update the store for modern requirements and provide future flexibility. These include:

  • new major east entrance building unifying the eastern range of the store
  • creation of the world’s largest accessories hall with bespoke architectural steel screens and engineered furniture
  • an award winning new 50m steel ramp bridge for HGVs to exit the basement loading bay, which cuts through and re-supports the original 1930s steel building above (as well one of the building’s stability cores)
  • creation of a new 2-storey subterranean tunnel from small structural modifications across the site to major retaining and basement structures
  • conversion of existing office floorplate to new escalator accessed retail
  • insertion of a new core through the existing historic classical east structure

Expedition’s role in the civil engineering works surrounding the buildings includes drainage design, hard landscaping and leading the coordination of below-ground services. As part of these roles, Expedition is working with a range of public and private stakeholders.

Expedition’s engineering approach reduced programme and allowed the store to remain fully operational during this ambitious redevelopment project.
