HI Emily Carpeting bedrooms is only dictated by your budget. The only variable is the price of the carpet, all other costs (installation, smoothedge, underlay) will be the same no matter what you choose. When you say remove wooden floors....do you know what is already installed? If you are only wanting to take the wood from the bedrooms but leave it in hallways etc, then the cost to remove wood planks (laminate?) may be around $20 per m2... A lot depends on how the timber was installed, so I think it's best to get in a professional and get a free quote. Good luck.

If you are seeking a truly open feel to the floor plan you have shared, then using one material in the mail living area is the best approach to making this space feel truly open. Using a variety of materials on flooring chops up the space and decreases the visual footprint. I would suggest using wood, tile, or if you are on a tight budget laminated flooring for the living/dining/kitchen. Then use carpet in the more intimate spaces; bedrooms and possibly hallway. Save the tile for the bathrooms.

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.

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.
