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

I'm guessing you are from NZ (kiwi) :) The handy sanders did our floors - http://www.handysanders.co.nz/. They did an AWESOME job and are reasonable priced. I would definitely recommend.

I'm no architect, but I agree with yours. Instead of large windows in the loft above the garage, what about a high, short, but long window....non opening? Here's some examples

Is there any way that you have the budget for wood flooring to be replicated the same as your Rimu? This would be the best option. If not a terracotta tile would look beautiful. Do you have any photos of the area? I'd be happy to be of assistance throughout your project if you'd like some one to one help and advice along the way feel free to email me directly.
