Altrincham Interchange
23rd August 2016

Architectural glazing systems by KAWNEER feature on the £19 million redevelopment of an integrated public transport interchange.

Kawneer’s AA100 SSG (Structurally Silicone Glazed) mullion-drained curtain walling with toggle fixings and concealed vents was used on the concourse of Altrincham Interchange in Cheshire, complemented by framing and 10D light/medium duty commercial entrance doors on a replacement link bridge.

The systems were specified by architects AHR for client TfGM (Transport for Greater Manchester) for the redevelopment.

The 19th Century rail station buildings and a substantial proportion of the platform canopy ironwork were retained, enhanced and brought back into use.

The scheme included the replacement of a 134-year-old bridge connecting the four rail platforms. A new 45-tonne pre-fabricated steel bridge was lifted into place in a single evening to minimise disruption to the travelling public.

From the outside it is possible to clearly see the red brick and stone façade of the station that was for so long hidden behind rows of bus stop platforms and islands.

The concourse roof featuring 50 solar panels is supported by two rows of steel columns and cantilevered back from the façade towards the historic buildings, while lightweight ETFE rooflights run along its length.

The Kawneer systems were installed by approved specialist sub-contractor SG Aluminium whose managing director Peter Taylor said: “Initially the design was for a total glass-bolted system but cost was paramount and Kawneer fitted the bill with the AA100 SSG giving a similar appearance from the outside.

“The minimum of profiles internally, with slim 50mm sightlines, also kept the architect happy so all parties were happy with the cost and the solution.”

The build was completed in three phases over two years as it took place around a fully working interchange on a fairly constrained site while keeping all three transport modes running.
