Kellogg College Hub – foundations completed

The Kellogg College Hub building, which is aims to be the first non-domestic Passivhaus in Oxfordshire, and the first for Oxford University, is now at the early stages of construction.

The foundations have been completed, and the ground floor insulation is being laid. EPS blocks are laid (the white material in the photo) onto which the slab will be poured. The dark coloured material in the photo is foam glass, which, as a structural insulator, provides a thermal-bridge free way of linking the building structure onto its foundations.
