As much as we love the look of the polished concrete floors, we're getting more negative (or at least not-so-good) feedback than positive. We've decided to go with floorboards. The negative was mostly around the cold. But between the colder room temp and the 7 star green energy rating we're achieving with our home, we've decided on the floorboards. - ProjectPete
For the typical home I wouldn't go past timber. It's beautiful, easy to keep clean, looks great for a long time without maintenance, and lovely underfoot. And it's not too hard years down the track to sand and polish so it looks like new again.
But we did choose to go with polished concrete for our backyard games room and we are happy with the choice (even with a few unexpected cracks). Now we've been through both a hot summer and a cold winter we haven't changed our mind that it was the right choice for an indoor/outdoor room. It's lovely in both summer and winter. - Jason
If it's engineered and done properly there's hardly any cracking. In my opinion it’s well worth the effort. just be aware of the pitfalls. Yes it is cold under foot. Alternatively, for concrete slabs you might also want to consider under slab heating. It's quite effective. - BIM_Engineer
Have to look at only using experienced professionals to do the job. Make sure you get referrals and they have high standards. My brother’s dream home was ruined by a cracked floor. Best of everything in that home and a small hairline crack right through the middle of the family room destroyed two years of hard work. - ST3V3
