    Are there any published regulations which govern the structural design of a 1.8 metre boundary wall?

    In case you are being influenced by a @bad build@:

    The key issue is ground conditions, hence its impossible to do off the back of a tin.

    The stability of the wall is paramount so at a minimum foundations should be three times the width of the wall, so 9" block on flat or 9" hollow block will have a foundation width of 30" with wall centered on it.

    If ground conditions are poor then it will need to be wider.

    It will need piers and expansion joints at every 5 or 6 meters or so, assuming everything in is on the same level and no steps in either wall or foundation.

    Then we need to look at both the thickness of the foundation and whether it needs steel reinforcing.

    The other consideration is ensuring the foundation is below the frost line.

    If the boundary is on your property, look at Land And Conveyancing Law Reform Act 2009, sect 43 to 47 inclusive

    Walls of that height often fall over (particularly in heavy winds) mainly because they were thrown up with no structural design.

    It's a bug bear of mine because children often play under these walls in gardens and little people are more likely to be hurt by a wall of that size falling on them.

    Give your engineer a shout. It'll be a small job for him but you'll benefit for years from the minor fee you pay him/her.
