Total height of 1.5 storey cottage

    I'm looking to build a 1.5 story modern cottage (two blocks with a connecting part). See this guide for what I mean.

    Meath CC recommend 7.3m/24ft height for 1.5 storeys.
    They recommend 8.2m/27ft for two stories.

    I'm worried we wont be able to get the first floor wall height to 6ft before the roof starts, so that we can walk into the wall/corners without having to bend our heads.

    Here are my rough calculations (I'm not an architect/builder/engineer and so this is why I'm asking the question). I will of course ask our architect when we start the design process.

    Ground floor ceiling height = 8ft
    First floor wall height until roof starts = 6ft (Allows us walk into walls!)
    Roof rise = 9ft (Based on span of about 20ft giving 38 degree angle, might need to make it little higher for 40 to 45 degree angle.)

    So that's a total of 8 + 6 + 9 = 23ft.
    We have 1ft left.
    So I'm unsure of:
    - How much height below ground floor floorboards? 1ft maybe?
    - How much space between ground floor ceiling and first floor? 2ft maybe?

    We will probably be using underfloor heating throughout the house.
    I think we would have to use concrete slabs to support the first floor screed also?

    Again, I've no previous experience of the construction industry so please excuse my ignorance!

    Thanks

    Width relates to height.

    Get it properly designed therefore no height issue exists.

    That's what we will do with our architect.
    I'm just curios to know the following:

    - generally how high off a level ground outside the house is the internal ground floor?

    - Roughly how much space is required between ground floor ceiling and first floor? Allowing for services space.

    1. usually minimum of 150mm... generally around 300mm

    2. a standard timber floor would be a 225mm joists with finishes either side so approx 260mm minimum. if going with concrete floors probably allow for bit more..


    BUT!!!!!

    you should not be trying to gunter a design to fit these restrictions... the restriction should be the frame work for a redesign to suit.
    there nothing that looks as bad as a house plan that was augmented to suit height restrictions when the original design was for a higher house.
