A perspective drawing which will give you a front, side realistic view of the exterior will help you decide, of course the most crucial and impactful part of an exterior is in the window style and size. Things like eaves, overhangs, entry design and symmetry all will change a basic floor plan, with so many ways to differentiate one common facade from another. Google sketch up will allow you to simply create this.

Couldn't agree more with the comments above. I would only add sheers; they add lovely filtered light and keep the room looking clean. The full scale of the sheers also adds a sense of luxury. I've included a photo of a master bedroom where there were different size windows and even doors to a verandah. Unfortunately the photo doesn't show the entire wall but hopefully you get the idea. All have block out blinds behind them too. And another bonus; sheers are not as expensive as most other window treatments.

So far......These are the light grey tiles around the pool. The coping of the pool is done with light grey Marble, and we got mosaics on outside around the spa - Still not finished yet.... Tilers are here today working :)) Hopefully hould be finished soon!

Is the first pic you posted an older one , maybe off the for sale ad ? It looks several shades yellower , but the gardens are quite different too . So that leads me to conclude it is fading on its own account -- that makes it easier IMO , just do nothing and it'll fade more ! Buttery yellow and brown were 80's , and pretty naff now , but instead of black , I'd go a Japanese Black -- a bit more matt , even blue hues there too -- more interesting , again just my opinion . The terracota does look slightly out of proportion , but lighter walls , darker trim and the orangeness of the terracota for interest would be my go , but then I'm not a fan of too much white on walls -- I'd prefer the 'relaxed casual' of a beige , jap black and terracota to crisp whites . I also assume that timber and the area to the 'right' of the stairs is the area closest to the street ? No matter what you do ( I'd go Jap Black stain on the wood , but do what YOU want ) I'd look at a bark garden or rock garden , with probably cactus and flax and reds and yellows and greens -- the timber looks too much in proportion to the render in the picture , so i'd soften that ( basically hide part of it ) . I like the character and it can get even better -- a great base ! Well done !
