    Can someone tell me what the current u.values of a suspended timber floor is these days,
    Would 100mm celotex between the joist and 18mm osb be enough? Cheers

    0.22 for a new ground floor or 0.25 for upgrading a ground floor, which I assume you’re referring to for a garage conversion? Use Celotex’s online u-value calculator to determine the build up as you’ll need the P/A figure too.

    You need to "try" to achieve the stated u-values for refurb work, but sometimes it's not possible - 0.25 W/(m2.K) for conversions. 100 celotex will be enough though

    BTW, do garage conversions need building regulations? Asking for a non-BCO friend :cautious:

    Yes you do. Wait... no you don’t. Wait... yes you should, but no not in theory as it doesn’t come under Regulation 6.3.y.h.7.9.5.z dated 1948 :cautious:

    Thanks guys for the replies. I have been asked by a friend of the family to look into converting one of their two integral garages into an office seen as they are both working from home at the moment. I can do half of it myself and I have a friend who is a plumber another who is a plasterer and another who is an electrician so I have most of it covered. I was wondering if it needed a planning application? My first instinct was it didn't as it is already part of the property, but then I was thinking it might because I will be removing one of the garage doors and bricking it up and putting a window in, so now I'm not sure!

    Typically, conversions only need planning permission if there is a planning condition on the original or previous planning permissions, or a general area removal of permitted development rights - new estates, special areas.

    I called the planning dept and they said that a planning application wasn't required only building reg's approval, for which I could send in some drawings and get prior approval or submit a building notice, either way a fee of £330 was required for site visits (n) ( photo's these days)

    Prior Approval is Planning, so nothing to do with BR’s.

    Your two BR options are a Full Plans or Building Notice application. The fees are usually the same but the FP application requires more information to be submitted, which goes through an approval process.

    Prior approval of the plans :rolleyes:

    If inspectors aren't inspecting, I wonder if anyone has challenged the actual site inspection fee they charge?
