two. Building function begins. The trench is excavated to suit the relevant floor circumstances, in this situation, to a depth of 450mm (minimal depth) for the footings. The common floor degree (within the region of the trench) is also reduced to a minimal of 300 mm beneath the DPC. Excavation exposes an underground pipe.

3. Concrete lintels ought to be placed to bridge the underground drainage pipe to stop the pipe being crushed. Also additional steel reinforcement mesh introduced to the concrete basis will provide additional assistance.

4. Stakes driven into the floor are set 450mm beneath DPC (Damp Proof Course) and 300mm beneath outdoors floor degree. Concrete is then poured into the 450mm deep trench to a depth of 150mm.

5. The concrete is floated to form a degree surface area 450mm beneath the house DPC

six. The internal leaf of the cavity wall is built up to floor degree, generally the house DPC.

7. Hardcore is laid to a minimal 100mm deep and compacted to form the base layer of the slab.

eight. A blinding screed of sand 50mm thick is laid over the compacted hardcore layer to stop any sharp stones puncturing the damp proof membrane (hefty duty plastic sheeting).

nine. The damp proof membrane is laid over the sand blinding and lapped onto the internal leaf of brickwork

ten. Optional floor insulation (50mm thick Styrofoam in this situation) is placed upon the sheeting.

11. Concrete 100mm thick is laid to bring the slab up to the completed floor degree which is then float completed to give a smooth finish for tiling or carpet finish

twelve. The outer leaf of the wall is built. In this situation, artificial stone to match the house is used

13. The internal leaf of the cavity wall is built to complete the basework. The same material as the outer leaf has been used to provide a feature stone finish

14. The PVCu external cill is fitted to the dwarf wall and erection of the side frames begins.

15. On completion of the frames the structural aluminium eaves beam is fitted to the head of the frames.

sixteen. The PVCu thermally clad aluminium glazing bars and ridge system are rapidly assembled.

17. The polycarbonate glazing panels are set up (alternatively, double glazed models may be specified).

18. The side frames are glazed after the roof is complete

19. The ventilated aluminium ridge is ready to accept the clip fit PVCu internal cladding. Electrical cables may be concealed behind the cladding if a fan or lights are needed.

20. The PVCu internal fascia is clipped onto the eaves beam to complete the internal finishing trims. Other internal function IS completed as soon as the roof is on
