I found a pic of your brick colour - it should look good up against timber, as the houses below have something similar. White trim would look great as a high contrast touch against the heavier walls and roof tiles.

Love the sofas - nice midcentury style with the angled legs, great colour too! If it were me? 1)Big colour art work on wall 2)Chrome lamp (arc) in corner that adds height but also provides a sort of "canopy" to frame the sofas and link the space 3) Floor rug - sisal? Textured? Perhaps a lighter tone/neutral to offset the navy and timber floors? - I love putting a larger sisal area rug under everything to link the space and group the furniture. Then I add a more textured/soft rug to add layers, textures and interest. The larger rug acts like a picture frame for the elements in your living area. 4) Coffee table - maybe round so little ones don't get hurt? Also provides movement and contrast against the straight lines and angles and ties in with the arc lamp. 5) finally, pillows and throws in chosen contrasting/ pop colour. Take that from your artwork! 6) clock in kitchen. Doesn't match midcentury design of sofas, but thats just me!

I don't know how big the existing plants were that have now been cut to ground level, but consider that as the root systems of these trees breaks down, there will be subsidence. This will then affect the paving surrounding your pool. I'm just mentioning this so that you are aware of the possibility in future years - it takes some time for this to happen, depending on the size of the trees and the root system. If they were all palms, then the problem may not be so bad as they have a fibrous root system. But underground can be as big a problem as above ground. If in doubt about what to put in pots, something as simple as a Lomandra grass-like plant would look really good - as long as each pot has the same plant. If you can get Lomandra Nyalla - this is a really good one and hardy.

Something like this beautiful Oak coffee table would be a better contrast to your rug without looking too heavy.www.urbanointeriors.co.nz
