    What are the limitations to doing something like this? What kind of cost is involved, I've heard that it is crazy expensive.

    I know the obvious advantage is no creaky floor noises but what are the other advantages\disadvantages?

    Thanks all!!

    wouldnt say its crazy expensive to be honest. most times it wont be that much more than a good quality sound proofed timber construction.

    as for costs, 200mm hollowcore slabs are at about €35/m2 now. Price is going up the whole time. You will then need to put a screed on this, and maybe a small thickness insulation board (depending on underfloor heating). This would cost approx €15/m2 for concrete, insulation and labour. Also, your ceilings downstairs will need a framing type system to hang the plasterboard from. wont add much to your overall ceiling costs of standard construction, maybe €3 or 4/m2.

    advantages, you can put in underfloor heating. it gives good insulation. great sound proofing. and can feel that bit more solid, no movement in the floor. It will cost more, but depends on what you want or can afford, but I personally think its worth it.

    Prices of less than €30 a sq metre in places.
    Advantages are many - sound proofing, fire rating, block walls can be built from the hollowcore, full floor can be dropped in one day.

    If you've kids and they like jumping off beds on to the floor up to 200 times a day then concrete floors are a god send...believe me, I've timber floors and 3 kids!!

    You're assuming OP is looking for a block house.........;).

    ...you can have conc floors in any kind of house, including timber-based. I have, in mine.

    And yes I have the ubiquitous noisy kids, as well.........

    Would I do it again..........probably not: there are modern silent floor systems that can cure the noise.

    IMO Not much more expensive than good quality timber joist floor.
    As above, Conc floors are good for sound proofing & fire proofing. You can have block walls on 1st floor that don't need to line up with ground floor walls.

    You will need to retain a Structural Engineer to design the lintels over all opes on the ground floor & to check wall dimensions & possibly foundation details.

    That's interesting, but I've a few questions!

    What kind of build-up is in a typical floor like this?
    Would it come in at the €50/55 m2 all in quoted above for concrete floor with screed etc?
    And could you install UFH with them?

    Another option would be to construct a timber floor and pour a liquid screed on top. UFH can be installed with this method. The added benefits are that you will get the solid floor benefits without losing Ceiling space and you can still run your services through the Timber joists / trusses. Also, there is no need for a separate ceiling support system as you will still be attaching plasterboard to the underside of the joists / trusses.

    I have done this a few times in Timber Frame construction and it has worked quite successfully. Unfortunately I am not sure of exact costs but from what I can remember it worked out cheaper than the hollowcore & Screed option.

    Your engineer will of course need to specify the floor construction to ensure it is able to carry the weight of the screed.

    are you talking about hollowcore. or shuttering it with a decks, so you can pour your own slab totally??. I saw this done recently. class job, probably expensive, but the lads did a lot of it DIY themselves.
