Hi all, I have almost finished designing a patio, which will join the back of the house. It is 20m long and of 3 different distances out from the house due to part of the house having an extension, part not and there being a garage joined to the side of the house. This sticks out further into the lawn than does the extension.The depths of the patio will be Extension part = 2.7m. No Extension part = 5.4 m, Behind garage part = 2.17m
The lawn edge of the patio will finish against a small retaining wall approx 250mm high. The top of the wall will be level with the lawn. From here, the drop down to the patio will allow it to be lower than the DPC of the house and provide falls to a line of ACO Brickslot Drainage ( Plastic) between the wall and the patio slabs furthest from the house.
The retaining wall will probably be engineering bricks on a concrete foundation. The wall is going to be faced with ‘Tier� natural stone panel system from CED 45 - 35 mm thick.
The patio is going to be laid in Donegal Quartzite 450mm width, random lengths. 20 - 30mm thickness
So that the Brickslot drainage is next to a full width (450mm) run of paving, rather than a run of ‘cut to width’ paving, it would be ideal if the patio was laid starting from the wall / drainage, working up the falls towards the house.
The position of the wall will allow for full runs 450mm wide until the back of the Garage is reached - this short length will be 330 wide ( 120mm cut off). When the Extension is reached - this run will be approx 400 wide (50mm cut off). When the house ‘No Extension’ is reached the row will be approx 350 wide ( 100 mm cut off). There will be no small width runs.
I intend to get a landscaper to lay this patio.
Question - Is there any major problem in working up from the lower part of the falls, from the drainage slot, rather than working downwards from the house, which I understand is the normal approach?
Recommendations on the best pointing which will not get any discoloration on the paving or other comments would be valued.
