Borras Construction, St Albans, won the prestigious contract to extend and refurbish Building 38, one of the original ‘H’ shaped buildings at the former RAF station.

The facetted patent glazing encloses a double storey space to the front of the building while the rear is being extended to create a multi-purpose seminar room, office and research facilities. It is part of a £4.3m redevelopment at Cranfield University.

Borras said the roof is supported by an exposed steel tree. Timber joists are made from graded, pressure treated softwood from authorised sources and are infilled with 18mm WPB plywood, covered with insulation, vapour barrier and waterproof membrane.

The building is due to be handed over next spring. Borras director Kelvin Insch said: “This is a prestigious project for Borras Construction.”
