The foundations and the footings built.
The oversite you see here is made
up from 150mm hardcore with a 40mm sand blinding followed by the 1200 gauge Damp
Proof Membrane then the 100mm cellotex insulation seen here. The joints are
taped and inspected by the Council then a 150mm concrete cap poured over the top.
Once the oversite is concreted the extension can take form.
There is a
100mm cavity with 100mm Thermolight blocks and 50mm cellotex cavity insulation
held in place with wall ties and buttons. Then there is the 100mm outside brick course. We are building on the back of the premises leaving the
existing kitchen extension in situ and building over the top of the whole
house to form the loft conversion without exposing the existing house to the weather.
