Thorndon Catchment Area Hampshire

Thorndon Catchment Area Hampshire: "The Foundations are in 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 then take form. There is a 100mm cavity with 100mm thermolight blocks with cellotex 50mm cavity insulation held in on the wall ties with buttons. Then the 100mm outside brick course. As you see we are building on the back of the premises and we are leaving the existing kitchen extension in situ and we will build over the top of the whole house to form the loft conversion with out exposing the existing house to the weather.

Here we are bolting on to one wall of the existing kitchen extension using firfix wall ties. The hole has been excavated for the drainage to be installed.

The new French doors are being positioned and held into place so as to be built in. The central supporting wall is also being built and firfixed to the existing house.

Cellotex cavity insulation held on with the wall ties and buttons.

The upvc windows are built in and the brickwork goes on up to the joist level. The joists are placed at 400mm centres and supported on the middle wall, and the joists that are to go over the existing kitchen are notched into the existing flat roof again so as not to break into the house until the last minute, keeping the customer happy.

Joists supported on the central wall and a concrete lintel over the door opening.

Joists at 400 centres.

The gable with ladder to the new roof being built in, and scaffold up to enable a cropped roof to be built above the bedroom's French doors.
