Hello everybody, I'm new to this forum so sorry if this post is in the wrong place. I work in Garden maintenance normally but have helped lay patios before. My friend has asked to help him with his patio and I am not sure if it is going to be possible to achieve what he (more specifically, his wife) is after.
As you can see in the image the DPC is one course below the threshold, and the air bricks sit on top of this.
They want the patio to be the same height as the indoor floor level, like you see in those glossy magazines.
I know that the patio should be 150mm below the dpc and that they could have a step but that isn't what they (she) wants.
The patio is already about 1m higher than the rest of the garden so a new retaining wall is going to have to be built.
I've seen various workarounds online that suggest leaving a 150 - 200 mm 'dry' area or a gravel channel with a perforated pipe in the bottom between the patio and the house. is this a suitable solution? would a surveyor be happy with this further down the line?
There is another bifold door to the right of this image and a downpipe comes down the rendered wall between them.
Thanks in advance for any help or confirmation you can offer.
