Here to stay as long it's properly polished!

How you finish your concrete floor will depend upon the look you're going for. To my mind, to have concrete floors that look to be an intentional choice you need to finish them with polishing (colouring is optional) Concrete floors if you've done your homework can cut your heating and cooling bills - if you've not and am unlucky it can make your home feel very cold in winter. They're great for keeping clean but can be a slippery when wet and not great if you've got littlies running around. The biggest thing to remember is if you're thinking about concrete floors you need to think about it before the pour as it's part of the build - vinyl can get put down at almost anytime so there's no time pressure using vinyl.

Budget and site. This can decide the structure quite quickly. The design and structure should be site specific. Slab on ground is the preferred option on a flat site due to speed and economies. A suspended timber floor on bearer's and joist's can sometime's be comparable cost wise on a flat site but is better suited if there's quite a bit to significant fall on the site. Suspended slab may be the most expensive compared to the other's.

We have done many homes that included polished concrete in bedrooms and throughout. In Melbourne people opt to have hydronic heating when doing a new build. The use of rugs Is a great way too mediate for any cold during winter months. Also any windows with direct sun light will mean that the concrete will warm up and hold that warmth. Thats one of my favourite things about concrete floors.
