I have just taken a couple more pictures (excuse the untidy house) from the stairs. As you can see it's an open plan area that isn't that big but very high ceilings also in wood (Macrocarpa) with dark wooden beams. The house is surrounded by bush so quite a dark house. I initially considered a darker wood similar to the beams but not sure if that will make the house appear smaller / darker...I'm really not sure what to do!?!?!? Thanks

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 Michelle - It looks like treated pine to me, and looks as though it has been recently built. If you did nothing it would fade to a grey colour within 6 months or so. This would probably blend in with the house quite well, and you wouldn't have to do a thing! Otherwise I would stain it - there are lots of stains on the market - see if there is one you like. A dark one would create a nice contrast with the house and make the fence look more like a feature. Good luck!

We are about to lay new carpet and before we do I want to tidy up the exposed beams in our lounge and master bedroom - see pictures below. I understand the vertical round beams are pine and the horizontal is macrocarpa. The vertical beams are in particularly bad shape - lots of pain marks, cracks, nail holes etc. I have been told by a number of builders the process is likely to be very laborious - I have the time but I am a complete novice. I would like to sand both beams back and stain them a matching natural medium toned colour - at the moment the tone of each looks quite different. They don't need to be perfect I just want them to look tidier than they currently are. Can anyone recommend what tools I might use for the vertical and horizontal beams to speed up the process? Any tips on materials, process to follow? And how I might fill in the numerous gaps in the vertical beams?
