The house is fairly small from the photo but elevated on a basement or garage plinth. If the base is brick, leave it as is. But whatever colour you chose, eliminate contrasts so if, say, a soft French grey, paint the walls, window and door joinery and roof flashing the same colour. A contract could be the new deck rail, but I would even consider painting it the same colour as the basement to link the 2 levels or just the same as the top. A bright glossy front door could break up the monotone.

You are asking Houzzers to do too much research. Post images of the colours and bricks etc and you are sure to get comments.

With a million variations through a million computer screens you will get a million suggestions and very confused while no closer to your answer. You have to do the work yourself and either get a colour match to a chip the min of a 50c piece or buy a Dulux or Taubmans fan deck and select a colour as close as you can. Alternately get a professional painter or decorator to use their fan deck or atlas to colour match for you and be prepared to pay them for their time.

I couldn’t fit the neighbours in. We are planning an extension out the back and will be laying a driveway and new lawn too.
