This is how I created a tiled sundeck:
1) Built tiled steps for access
2) Rendered & painted the supporting wall facing the swimming pool
3) Screeded the base for the sundeck
4) Laid the floor tiles on the screeded base
5) Fitted the balustrade to enclose the sundeck
To extend the kitchen we had to knock thru the back wall, block up the arches by inserting a double glazed door and double glazed window. Also: (i) Rendered & painted the exterior walls (ii) Built tiled step and fixed skirting tiles
Parts of the pebble-dash coat on the front wall of this house had "blown". I repaired and re-pebble-dashed these damaged areas before the whole of the front of the house was painted.
