Construction work has begun on REID architecture’s SkyHub project at Glasgow International Airport for BAA Scotland. The scheme will deliver the first phase of the practice’s development strategy created for the airport in response to the Government’s White Paper on the future of air transport.A new central search facility on the first floor of a 4,000sqm extension will facilitate the conversion of current landside retail to airside, providing significant commercial and operational benefits. The alterations will create a departure lounge common to both domestic and international passengers with a significant increase of net retail space.The use of natural daylight has been optimised to improve both the quality of the spaces and energy efficiency. One of the proposals is for the south-facing façade of the search area to be constructed in a translucent, insulated material which will flood the internal space with light, whilst preventing glare and solar gain. The extension has been designed to allow for further expansion upwards, through the addition of a third floor, for commercial office space.The project has an extremely challenging schedule, with the facilities due to be handed over in Autumn 2008.
