    Hi

    We have recieved planning permission to renovate and extend, to a two storey,a 1970s bungalow. The engineer has assessed the foundations and they not the best :(, so we have to use a timber frame structure for the 2nd storey. The house is cavity wall built. Im just wondering has anyone carried out this type of build or knows any timber frame company that supply this type of product. Have contacted some companies and only have one positive result so far. :eek:

    Thanks

    Have a look at some of the other threads here on TFH: am interested in what exactly u got planning for from the perspective of what cladding/outer-leaf u will use: I read in post here that some insurance companies wont insure a TFH unless the outer leaf is brick so this maybe too heavy for the founds.
    Have u considered the whole house from an airtightness/insulation perspective?
    have u considered knocking and rebuiling from scratch, with insulated foundations etc?

    We hoping to use a extra lite block with the timber frame, the planners want smooth render finish as per the current house. Basicially we knocking the house back to the four external walls, and taking up the floors, knocking the whole house is not an option so we trying to do the best we can with what we have. We hoping to externally insulate the house and have it as airtight as possible with a mhrv. Never heard about the insurance issue :confused:- must add that to the long long list of things to look into.

    They basically ask if the stucture contains brick or concrete.

    So traditional block, traditional irish timber frame, ICF, externally insulated block are all fine. Timber cladded or cement panel board timber frame is where you will start to hit restrictions.

    I spoke to an owner of a home from that well known closed panel tf galway based company and he explained this to me. He didn't think it was that big an issue.

    My original post was more a "just be careful" basically.

    "Extra lite" blocks such as quinnlites are effectively concrete products. I'd imagine there isn't an issue with them.
