Not sure where the home is located, I think concrete floors are a great choice for homes in warmer climates, the lime color would be neat.. but may not be attractive to many if thinking about re-selling home anytime in the future.. usually rusty tones or grays tend to be more neutral.

I have tumbled travertine (basically a form of marble) in the master bedroom and a marble mosaic in the master bath. It is higher maintenance. It stains and it wears differently in different areas. I am not doing natural stone in my new home. There are some fantastic tiles now that mimic all the stones, and a good quality porcelain tile will be very durable. Some ceramic wall tiles are "weaker" but I have had excellent luck with porcelain tile. Granite floors. Sure. But as people have said they also require maintenance like periodic sealing etc. In a house that size you don't want a different kind of floor in every room. I would stick to one or perhaps two types of floor tile in the main rooms. You can get away with additional types on walls in the bathrooms but I would keep the floors consistent. As far as cost goes, there is a very broad range of tiles and stones. In my shopping I have found some very good high quality floor tiles for reasonable prices. Stone has priced out higher...at least the ones I have looked at. Good luck!

First, I think rearranging your furniture and getting the furniture off the walls and float them in the living space would look nice. I'd nail down the arrangement before selecting new rugs. Where the chandelier is, try floating your sitting area (with the coffee table) below the chandelier and angle the current area rug. It's okay (and looks quite cozy and open) to have furniture floating and be able to wall around the furniture. You could have another seating area where the arrangement is now. Oh...yes, your mustard walls can work as is. Let's start with the layout first. :)

You need to post this in design dilemma ,not before and after
