I have a 49 meters squared garden with natural grass + some concrete. I would like to change that to artificial grass and add a concrete pathway to walk to the summer house. Next, to the summer house, we have space where we have cut down a tree and would like to put a shed instead (nothing fancy). I also have a beautiful deck, however, on the decking I have a plant area which grows random plants. I would like to remove that with just soil for us to plant our own flowers etc. Could you please give me a quote on how much all that would cost.
