Carpet has come under fire because of the allergy/asthma reactions. Carpet can hold dozens of pounds of human skin/dust/mites in it. It can never be fully cleaned nor can the dust be completely removed. Because of this, many people are looking for solid flooring options which reduce allergens, reduce asthmatic events, are easier to clean and last longer. High end carpet (the stuff that is worth more than hardwood) still has its place in high end homes - often times in luxury bedrooms/luxury appartments (noise issues have to be taken into consideration) but on the whole, the general public is shying away from wall-to-wall carpets. Cork flooring is seeing a huge increase in sales because it "takes over" for carpet. Soft, quiet, warm, easy to clean, hypo-allergenic, antimicrobial, instect resistant. It is the "go-between" type of flooring for people used to carpet who need to move to solid surfaces for their health. As Canadians, we love this flooring because it is so warm.

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.

Paint your house and ceiling first. You are probably asking for trouble if you put the floors down only to paint over the top of them. If you can, remove the tiles in the kitchen and paint just behind the line of the splashback too. Once painting is done replace kitchen benchtop then splashback. I would call the bathroom its own job and do it individually, unless you only need to paint the ceiling and if a tiler doesn't need to be brought in for anything else in the house? A lot of bathrooms now are getting tiled from floor to the ceiling if this is the case, paint the ceiling first, then tile. If walls need to be painted, it wouldn't really matter if you did them first or last, though if you did it first expect to do some touch-ups. I guess if you really wanted, you could do the first coat before tiles then second after... I don't exactly like stopping and starting painting, so I would do the walls (if they needed to be done) in one hit, after its been tiled. Well that's the order in which I would do everything... Really, for what you're asking, the painting could be done at anytime, but to make life easy on yourself, I would definitely recommend doing it before the floor.

I think, like you said, due to the fact that there's a larger space when it comes to the hotel lobbies is the reason as to why it works. I think that no matter what you put on the walls (whether it be concrete or marble) will result in tiles not working out. The industrial look tends to be exposed brickwork anyway, or cream or white colours so maybe that's an option you could look into. What did you end up doing?
