      Hey Folks

      Been a while since i’ve been around this way but good to see Archeire is still going strong.

      Anyways, i have a wee question for ye that are familiar with the Building Regs (yawn)s. It’s a little dull i know, but here goes:

      I’m currently in exile, designing a house in Ireland. I want to have a clear floor to ceiling height of 2.7 metres on ground floor, and maybe 1st floor.
      However, I see in the TGD’s part A- Structure that it says Floor to Floor heights should not exceed 2.7 metres
      ie, Floor to ceiling approx 2.4, which to me seems a fairly stingy maximum height.
      So my question basically is what are the consequences of going outside this Maximum height stated in the TGDs.
      Do i need a special structure? Do i have to get an engineer on board?

      Does anyone have any experience with this issue?
      I find it hard to believe that 2.4m is the maximum height of a room in ireland…

      Thanking you

      i’ve built houses with floor to ceiling heights exceeding 11′ (3.3m). can’t imagine why it would be a problem. are you sure you’re reading it right? quote it here if possible.

      Cannot imagine that there would be a maximum room height – seems overly constrictive

      i know- seems ridiculous doesnt it?

      Quote from TGD part A, page 8, Par
      “The floor to floor and ceiling to ceiling heights should not exceed 2.7m”

      It is part of the Structure section so i gues it has to do with the stability of a standard cavuty wall construction, rather than regulating the height of rooms..
      But if i go outside these limits do i need an engineer to verify the design?

      thanks for the replies

      It doesn’t limit you to these dimensions. It means that, provided your building is within these limits, it’s deemed to satisfy the structural requirements, but anything outside these limits needs to be checked against the relevant codes. You don’t need an engineer: it’s not a complex anaysis, and it’s well within the capabilities of any architect. I say this as an engineer, by the way.
