Get the professional sander guys in to repair the living areas and kitchen but don't go too dark with the stain as it will kill the lovely grain in the matai. I'm thinking a couple of tones richer than the timber knots showing in your photo, definitely no yellow tone at all. In NZ stepping on to carpet especially in a kiwi winter is so much nicer than a cold floor board shock!!! A nice area rug for the lounge and you're done.

To me it looks like it would be better to have a smaller kitchen as being a 1 bedroom place the living/ kitchen area is quite small. I think having the essentials along the bedroom wall is good but the island makes the living area too small in the first plan, and in the second the cabinets make the walkway too narrow. I would put sink, fridge, oven along the bedroom wall then make any other bench and storage space more like moveable furniture to make the living area seem bigger. The kitchen may be able to be shut off behind doors (a bit like a euro laundry) when not in use to make a much bigger living room, especially if it isn't used a lot.

We currently have a deck on the first floor over the garage. It construction is wood with a water proof membrane over, that is now leaking, with carpet that is used on boats over the top. What would be the lightest and best floor covering to use when we re do the deck?

replaced the old bath in an upstairs flat and trying to find the best solution!
