Hi Aleta1, youre getting down to the nitty gritty of Interior Design now. Choosing the perfect colour involves addressing many issues...size of your windows, orientation of the house, height of ceilings, size of rooms, purpose for room to name a few. If you have the time I recommend getting a sample pot of full and half strength and try it in a couple of corners of each room. That way you can see how the colour looks at different angles. Good luck.

I've just been looking at your colours, I think the Dulux Dieskau would work the best with the other colours you have to work with, choosing colours is such a personal thing and I know it can be really hard to choose and hope you make the correct choice. Oskuee is right, a paint job can look terrible half way through so you need to make sure you finish to get the proper look of colour. But the biggest thing to remember is it's only paint and it's the cheapest thing to change so if your not happy with the colour you choose you can always try something else. Happy redecorating :)

That’s a good idea, we’re going to go with painter on the first room, once he leaves we can decide whether or not we paint the trims. More work, but playing it safe!

I would match the new timber to the colour of your gutter as it is attached to the house. The merbau decking is a great colour so I wouldn't do anything else but the stain in your photo. I can't see any concrete in your photos, and I would question whether it needs to be painted? Quite often painted concrete wears and needs repainting. If you can't live with the bare concrete consider a concrete treatment and imprint pattern where the colour is mixed in with the concrete and lasts forever.
