New Build Attic Conversion

    Just a quick query if anyone has any info. We have a deposit down on a new build. We'd like to convert the attic.

    Im wondering is there an option for the builder to floor the attic in preparation for a conversion.

    If anyone has heard of this before or could shed some light, it would be much appreciated.

    Whether it is even possible would depend on the type of roof truss. There may not be the open space under the roof. Are the joists spec'ed to support the additional weight?

    If it is meant to be living space there's a whole world or additional building regulations for a three story house v a two story house.

    It's not as simple as laying down a few floorboards.

    Im unsure if the roof Truss just yet. We've only seen the outside, apex is quite big so thats what got me thinking.

    We'll be getting a look inside over the next couple of weeks. Thats when I've been told the communication with the builder happens.

    I heard through third party that a friend of there's had flooring out down before they moved in. Cost a bit extra but yeah your absolutely right about how its laid out above. Sure we'll know in duw course

    Thanks for the info

    The roof truss must be correct to allow conversion.

    Here's a link to some roof conversion FAQs. Get onto your builder ASAP if you want it done. They'll need to make provisions to add the staircase, add rooflights, maybe add power and plumbing.

    A bit of upfront cost could save you thousands in the long run.

    Please be aware that converting a attic is a lot more complicated than it looks. You could risk bypassing airtightness measure, makin the house cooler and nosier in winter. So just ensure the firm knows what they are doing.
