Dulux Charcoal on the timber and also paint the orange tiles under the window on the timber side. Too many orange stripes, the other two match so I'd leave them. Paint windows and trim Whisper white, paint the top gutter against the roof charcoal and the trim under in Whisper white. Also paint the door step in charcoal. Like your house, all the different textures just need to compliment each other. I'm building mid century design now, I'm using all different textures too.

depends on how you like to live, local climate, ages of people living in the house, how many separate rooms you need (eg the study would be big enough for a small single bedroom but a bit too cramped for a double guest room and it's useful to work out how you would use every room..eg the bedroom next to the laundry is big enough for a double bedroom or playroom but not a very good room during the day for small kids away from supervision and that corner might be better for the private master suite and keep the lounge study at the front to enjoy the northern aspect and some people prefer the master bedroom grouped with the children's rooms but there you would have size and budget restriction and raked ceiling and clerestory windows are more complicated in this shaped house and would add lots of extra expense...what do you mean by open up the courtyard??...maybe the house could be closer to the south fence and have the "backyard" along the east...more of an L shape rather than a U??

as big reader says there are many suitable project homes that could be modified or employ an architect to design a new home but, first task is to understand the block and create a site plan.. please describe the local climate, is it a standard rectangle (43 x 60?) or a more complex shape, does it slope in any direction, what is the setback or any easements from every boundary, are there any existing trees, gulleys and/or potential dam sites, how do you plan to use the extra shed, do you have any plans for gardens, animals or special hobbies, where is the front gate, will you need/want tank water, solar power and a septic system, will there be town water, power, phone (pole or underground?) and where do they enter the block, do you expect to have regular overnight guests and how will you use all the bedrooms ....imo many homes suited to suburban sites are not suitable for rural settings and it's a shame to squash the house into a small shape when a more spread out designs with links, breezeways and courtyards can make better use of all that space and make lovely sheltered outdoor areas...having built and lived in several homes on acreage and now retired i would be pleased to share some of our best ideas but more information about the block would be useful

I am not asking if you need a window in the master bedroom. This is what I asked. So the street is to the east? And the master bedroom will be at the western end and you can't put the window on the north, which is ideal, or the south? I cannot imagine the bedroom at the back having only one external wall, but perhaps I am imagining it incorrectly. What I wondered is why can't you put the window on the north or south instead of the west? Can you explain more please. I will add the question, if you have a builder does that mean you have a floorplan already?
