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 love a QUALITY paint job. Few people know the ins and outs of a quality paint job but, a seasoned painter for INTERIORS will have many techniques and processes to dial up the end result. I love my painter and I listen closely to his advice and he is so expert (40 years) and good that he makes it look effortless. BUT IT'S NOT. Will find and post favorite picture of painted trim here. I think the secret is style and proportion of trim and then the quality of the finishing. Did you know most paint curing really needs 2 to 3 weeks to set up as a really good tough finish? "In a hurry" is the curse we mostly experience for improving interiors. I wonder sometimes how different things would be if people took the right amount of time to do things in the time frame related to that finishing task!

Thanks for all the great ideas everyone and sorry I didn't explain the polycarbonate a bit better :) This is along the lines of what we'll be using... http://www.psp.co.nz/building-brands/corrugated-sheeting/suntuf-polycarbonate The area is an absolute sun trap and we're hoping to use it as an extension to our living space, especially on rainy days! I've just sent my husband out to get a few pots of different stains for is to try - darkest brown (cedar) and a lighter brown (rustic oak) both by Cabots + the black we already have. Hopefully we can decide between one of those! I probably should have mentioned we will have black aluminium pool fencing running along the top of the second retaining wall - so the real question is do we keep everything black (pool fencing, horizontal fence, retaining walls and pergola) or do we go with a dark (or even light) brown for the pergola and retaining walls.... We just keep going around in circles at the moment. Decisions, decisions! Thanks again :)

Hi, Courtney, thanks for that, I haven't painted yet, we have nearly finished putting in a bathroom. This coming summer we are painting, so at present my choice of colours are a dark grey roof, a warm green (not blue undertone) for main house, a buttermilk trim and a rusty red door? What do you think.
