    Hey,

    Has anyone a blog about building a timber frame 2 storey house or any recommendations on companies etc.

    Can't find much info from people who have built with it.

    Pros and cons.

    Can you have a concrete first floor or does it have to be joists?
    Soundproofing etc.

    Any help appreciated.

    If you want concrete first floors then traditional block built it is.

    Up the road from me there is a one off new build ICF. Ist floor precast craned in.

    Would ICF be able to support slab or might there be some steel helping ?

    ICF will be able to support slab in most cases (certainly in any case where block could). Some of the ICF systems also have an integrated poured floor system.

    I'm just finishing off a two storey timber frame and I have a 50mm concrete screed on the 1st floor so it can certainly be done. Engineer spec'd 253mm eco joists to support the weight and spans.

    There's a difference between a timber floor structure supporting a concrete screed and a concrete floor structure supporting a concrete screed.

    When someone talks about a "concrete" first floor it is worth clarifying which of the above they mean!

    The OP mentioned Concrete First Floor. If its a screed they are talking about, then this whole thread can go in a different direction. Two separate things with 2 different answers.

    I just meant any concrete barrier between floors, I currently live in a house with timber joists supporting the floor and the noise travels through like there's nothing there

    Thanks for the reply.
    What company did you use to do the timber frame?

    Why did you decide to go for timber over block?

    Trying to figure out which suits me best.

    I had -snip- do the timber frame kit but I would not recommend them to anyone. They delayed us for months and their quality of workmanship and attitude was terrible.

    Ironically I went with timber frame for speed, I wanted to be in the house for September for kids starting school but because of the supplier and covid that didn't happen. Also I wanted to get as close to passive spec as i could.

    If going timber frame I would advise to get an NSAI certified company to do it for you.

    Legally they have to be registered with the NSAI.

    I remember some controversy on a development where it turned out the timber frame supplier didn't have NSAI certification recently enough, wonder is this the same company.

    Certainly 1st floor screed is no problem and very common with timber frame.
    Hollowcore 1st floor would be crazy.

    The only way to do a slab first floor would be to build block or steel supports, negating the point in going TF in the first place.

    Yes id agree fully. While its common to have alot of steel built into larger timber frame structures, wanting a hollowcore first floor would basically result in a steel framed structure with timber infill.
    No sense at all to that.

    Hey just hopping on the post here, hope you don’t mind.

    Just a quick question.. does anyone know what quality timber new builds are built to these days?

    And generally what is the pros and cons for timber new builds v’s concrete builds?

    If the timber new build is A2 energy rating does it mean that it has concrete in it already has it would have to be heavily insulated? TIA

    Hey,

    Did you get any recommendations or warnings for Timber Frame companies? Would you mind sending me a PM of them if you have please? Looking to build a Timber frame and want to compare the quote to any reviews.

    Thanks.
