    Ok, well we are looking at buying a 1980s house. Our own house is sale agreed subject to a retention permission coming through for it so in the next few weeks we would hope to be moving on buying.
    My question is this,
    The house needs structural repairs internally and as such we are planning to pretty much start from scratch with it. Its a simple single storey house and we are delighted with the location and the price so are happy to put cash into it.
    We plan on applying for permission to raise the roof to a more modern pitch and build a room to the rear of 7m x 5m and maybe modernise the front elevation in terms of window shape etc We will not be converting the roof space in the near future.
    We plan to alter the internal layout somewhat depending on what can be done structurally and it will be 100% refit throughout.
    So with all that in mind, are we still exempt from the requirements of the latest building control regulations considering the increase in footprint is less than the 40 sqm limit.
    Also, any comments on what is the best way to bring the external wall up to current standards in terms of insulation. Its a double block wall with 80mm gap. We are redoing structural floors so will be insulating well in that regard.

    Fill the cavity first, then move the windows out flush with the external walls and externally insulate the walls.
    Also don't forget about air tightness and ventilation.

    1. So with all that in mind, are we still exempt from the requirements of the latest building control regulations considering the increase in footprint is less than the 40 sqm limit.

    1. imo yes your exempt for the new building control regs, but you still need to comply with current building regs, h&s regs and planning regs. when your architect is designing the extension and specifying the upgrade works s/he will check the finer details.
    2. pump cavity, and install external wall insulation.

    To the best of my knowledge, your not exempt from the requirements of the latest building control regulations, you are applying for planning permission and will therefore require a commencement notice and hence you are subject to the requirements of the latest building control regulations.

    Also I believe that there is a max number of "days on site" requirement to satisfy to avoid the latest building control regulations and by the description of the works id imagine that you will exceed that too.

    You are not exempt from the current Building Control Regulations.
    You will need to lodge a Commencement Notice for the works and these works will need to comply with the current technical requirements of the Building Regulations.

    You will only need a short form of commencement though, and will not require an Assigned Certifier.

    1. Extension is less than 40m2 so the latest building control Rega do not apply
    2. The number of days on site relates to the health & safety regs.

    If you do not extend the floor area by greater than 40sq m, you do not have to comply with SI 9 In regards to appointments

    If you start on the 6th thursday of the month and finish on a bank holiday Tuesday your exempt for everything and get a €3 winning streak ticket.

    Just thought Id add to the OP's confusion.

    EVERYONE is confused about SI9

    There is contradictory information bringing released almost daily and its definitely looks like a 'make it up as you go along' piece of legislation.

    Terrible indictment of the department, the "stakeholders", and the writers of the law. ..... that we have this situation over a year after its enacted.
