Not sure on which way it faces but when the sun is high up there is plenty of sunshine coming through.
I am not bothered about parking for two cars as I have a garage, driveway and then there is parking outside on the pavement too.
I checked with council they said as long as it is permeable for water to soak through it would be ok, I heard there is block paving that allows for this but might be wrong.
My raised beds weren't going to be too high, I was just going to get some Everedge to seperate the soil from gravel, so I guess it is a little bit raised. I don't mind watering flowers its more the lawn.
I have looked on the Crocus page before but not seen that service so its look cheap so will give it a go for a nice design. I was looking to get a garden designer in but cost was too much so figured if I go down the gravel root I could design and do it all myself.
