Currently live in a house with a small north facing yard which is concrete. The part against the house is wet for the whole of winter as it is in shadow. We are moving house to another place with a north facing garden. Needs a new patio and I’d be interested in ideas for a surface that might actually dry? I was thinking gravel may be best (maybe with stepping stones) or I’ve seen resin bound driveways recommended as being good for drainage. Any thoughts?
