Keep the lounge away from the wall and it'll look bigger.

try going to Hamilton Parker on Lenard ave. off 670 it is in downtown area and will give you great ideas.

This just popped up , but I see it is quite old . Did you decide on paint colours ? The roof looks almost a brown tone in the photos , but you say it is dark grey . I assume you don't want to paint that ? If you do , go more charcoal IMO . If you don't , I'm assumimg it will look several shades darker with your wall colour choices . There is a roller door on the garage that appears to be a nice shade of orangey yellow . Personally , I would go with your colour choices , but do all the doors ( roller doors , wooden doors ) and gutterings in that ochre shade . Your terrace I would do in a charcoal , but with the top rail either in the orangey yellow , or a really crisp white . I know that sounds a bit 70's ( although they would have added a lot of ranch brown back then haha ! ) but against the light grey I suspect it would work together well , and look the part .

Im trying to choose colors for a new house, we have been suggested the color Narrow Neck 1/2.....wondering if any one has pictures of a room done in this color Dulux... Thanks
