We are going with underfloor heating in our open-plan living room/dining room/kitchen (an inverted L-shape with the living room off the hallway and the kitchen and dining room to the rear of the house, adjacent to the garden). As they are all connected, we'd like to keep the same flooring surface throughout. I've been reading that from an insulation point of view, a wooden floor (albeit engineered wood) is not really ideal, so I was thinking of tiles throughout the ground floor (including hallway and study in the side extension), some sort of natural stone tiles.
My question is - does it look tacky? I know it's popular on the continent but would it make the house hard to sell in the future? Why is it not a more common practice here in the UK? Do people feel they are too cold (shouldn't be if underfloor heating and use of rugs), impractical (again, tiles would be easier to install, keep the place super clean) or is it just a matter of different taste?
We're in SW London and we're undergoing full refurbishment of a 1930's house, aiming for a contemporary look.
