A vibrant street frontage of curved, organic shapes was the primary concept. Bright retail ‘pods’ filter pedestrian flow and connects the internal street of the interchange with the bus zone and existing urban fabric. Creating a warm, safe and attractive environment was important and so we wanted to flood the space with natural light. An ETFE roof was incorporated into the design so that the glazed street would be protected from the elements but would enable a feeling of lofty open space with uplifting lighting. Advanced 3D modelling helped us to develop the building concept into a rational engineered design.
Built on an existing Brownfield site, the build was designed to be environmentally conscious through the use of locally sourced natural sandstone, recyclable copper and glu-laminated timber from sustainable forests. In addition to the Interchange building, the contract included the relocation of two existing operations into new buildings (a bookmaker and an engineering office); a temporary bus station on the “other” side of the railway and the construction of a new road. These other works enabled the Interchange to be constructed on a vacated site with only limited demolition required of the existing shop units on the Midland Street boundary.
Bright and inviting, the design marks a real departure from the colourless, characterless architecture it replaces. The new bridge, a covered extension to the interchange building itself, gives a seamless transition between rail and road transport. Sustainability has been maximised through the use of sustainable source and recyclable materials, and design features that use natural daylight and ventilation. The solid areas of the roofing use sheet copper, easy to shape to the complex layout of the building and attractive when seen from above in part of the new town centre development.
