    Anyone know anything about building a cob house? Are there any special planning requirements? Are they suitable for the damp Irish climate?

    I found some useful Q & A here when I was looking for info a while back.

    They would be suitable for the irish climate, and there would be no planning requirements relating to the cob directly. However many LAs would have finishes restrictions, and cob obviously has a limited range here

    What do you mean by finishes restrictions, and how would cob limit that?

    I only found out about cob houses quite recently, and love the idea.
    Myself and my partner will definitely aspire to building one of these in the future.

    This place http://theholliesonline.com/ run courses in natural building so I think myself and the boyf will do one next year. We've always been interested in the idea of an eco friendly/ natural home, but it always seemed out of our grasp. The Hollies place is great as it's in Ireland, so I would imagine they have all the answers to planning permission/ building difficulties questions.

    fair play to you, the hollies is an interesting place, I've been meaning to go down and check out their earth floor.
    you should also have a look at straw bale and hemp-lime construction, or a variation of rammed earth/cob. with any of these methods the 'boots and hat' ie footings and roof overhangs are of the utmost importance.

    PS. I wouldnt be too sure that the hollies are the people to talk to regarding building regulations and planning requirements

    The main planning obstacle that Cob builders in Ireland seem to face is meeting the required R / U Values in terms of thermal regulations.

    For that reason these folks in Sligo had to have the North wall of their Eco home made from Straw Bale.

    Here's a wee video about their house.

    Cheers,
    S.

    planning is dependant suitability of the site/location and how well the dwelling is designed to suit.
    I'd see The new Building control act as a bigger issue than planning.
    As regards building regulations, Using natural insulations such as straw/hemplime, with cob/rammed earth construction makes sense

    Thanks BryanF

    I was aware of that; however as they had personally built the house they live in and were typifying the point I was trying to make I thought it would be ok....Duly noted, however.

    I'll have a further read of the Building Control Act, too - thanks for the reminder!

    Cheers,
    S
