Thanks Sam,
Well I didn't get time to go out this weekend and check out, will definitely have a look this week sometime. My other problem is I have network of pipes on the side of the wall where the roof will be connected, its a mid terraced house. I am in a dilemma as to how to work around it. Can anybody recommend someone to build a roof over the deck. I have now even started thinking about awnings, although don't know whether I can get transperant awnings from anywhere to let in the sun. If anybody has been in my situation, please guide me.
Regards
Ruby
