New Vet Surgery passive base

In one week these amazing guys from MBC Timber, Harry, Shaun, Brian and Tony, working from 7 till 7 every day of the week, have installed the insulation base laid on compacted stone with steel mesh and underfloor heating  laid over.  Eco-Concrete will be poured next week inside the base  in readiness for the off-site timber  frame arriving in two weeks. This design means the concrete floor is completely insulated and will act as a thermal store, cooling in the summer and warming in the winter,  minimising the need for heating in this building. The building inspector had never seen this type of construction before. Its quite common elsewhere in Europe  and being adopted more now in the UK- which is why these guys are working flat out at the moment!
