I think the colour of your chair, the darker tone probably but you could try swatches of both.That also seems to be background colour of the floor rug, all look a similar tone and would blend nicely. Keep neutral and maybe even try a charcoal gray . Whatever you choose needs to tone with the lovely wood of the beautiful chairs.

Did you decide which timber to use. Carpet squares work well just make sure the over locked edge isn't too tight as it will cause the carpet to curl up, you can also use sisal the same way which you can take outside and hose down. With your table and chairs on timber it's all a bit timber and would be an idea to just keep the two carver chairs at the end of the table and introduce some other chairs to soften the setting, could also be better chairs for little ones to sit in.

siriuskey, Yes, the courtyard is open to the sky (no roof over it), I assume this is what you mean by double story. Ref. below photos, I would love to get this look, especially the first and last photo, where you can see family living space from the first floor. I can't achieve this in my plan as it eats a lot of floor space upstairs. The referred plan (photos) has a very big void combining staircase, hallway and dining area. I know it is not easy with cooling and heating when you have such a big void. So, I explored a few ideas (with my limited knowledge on this topic) before achieving the current floorplan. I have also thought about, in my current plan, extending the void on the staircase to the dining area (it is more like L shape) but i wasn't sure if that makes any difference. keen to hear your thoughts.

Melissa, if you have children forget any sheepskin throws over the bench. wood metal and vinyls are the easiest to clean/maintain. Do you have any colour?- yellow or orange would look great against the blue rug and would look good with you material piecs..
