The house looks very livable. I love that you have concentrated on creating one nice bath with separate walk in shower and a windowed tub! Since you have already thought of it, I'm going to assume that the attic is for future expansion and cannot be adapted for use as the current "away room." We are also in the process of designing a small house, and we've designated our study as the "away room." Ours will open off the dining room. If you switched the locations of the Study and Bed 1 on the same side, you could put french doors or an extra wide door with etched or decorative glass from the hallway into the right hand corner of the study. This would give you a really long diagonal view through the lounge and out the french doors, and from the lounge through the study to the window at the far end... The study window should be increased in width to match the neighboring window in Bed 1, and it then becomes ripe for a small window seat, either a clip on bay bumping out, or a "built-in" bay using narrow built ins on either side. Or both: build "in" for now, putting file cabinet drawers under the window seat, and angled corner units in for storage, and add the bump out bay later when you know whether your offspring would prefer a really cute desk, or a window seat, or a bed nook. You would, alas, lose the door from Bed 1 into the bath.... but honestly, there are lot of doors into that bathroom already, and that one has substantial collision potential. It might be best to make the single access point that door from the laundry. Either a glass panel set high in the bath room doors or a transome would make it easy to tell when someone is in the loo. Other ideas would be to split the nook under the stairs, so that half the depth opens to the lounge, and the other half to Bed2... with the wall thickness, you probably get close to 600mm or 2' on each side. Add a deep bookcase or other built in, and you're easily at a depth that makes both spaces very tucked in. Lastly, if funds allow a shallow bay window over the kitchen sink would visually expand the kitchen, particularly if you could arrange it so that the counter runs right into the bay.

As the appearance of the garden has a modernist style with the straight lines and concrete furniture how about a Mondrian influence and add a bold strip of blue? It is a pond and with the right shade it could look really relaxed and contemporary. My daughter's suggestion is a chalky lilac!

i think that a mini-subway tile in a carrera marble and gray colored grout could be stunning in here. subway shaped tiles are both modern and classic and will never go out of style...your options are really limitless. this space appears to be open to another, if you add color to the kitchen, be sure that it makes sense with the adjacent room. this space is going to be great!! already gorgeous! keep us posted!

Black and yellow are both very strong colour choices and I feel you'd be sick of them before it was time to change them. Black also shows marks more than you'd think. Clear is fine, but have you considered a piece of art behind clear?There are several companies that do this, imageglass.co.nz had one with tuis in it which has black and yellow. As for size are you having a range hood? If so this might affect your choice of size.
