The boss man has arranged to have our street cleared and jetwashed tomorrow which is only right but he is keeping a rather low profile otherwise! I believe he is trying to blame the wall that runs alongside the steps for collapsing, rather than anything he has done. Problem with this line of argument is 1) the original wall -prior to him commencing work on the property-had been there for nigh on a century with no problems whatsoever and 2) he actually added to this wall himself and it is also this most recent work that has fallen over. It seems self evident to me that neither the 2 walls behind the property nor the one running at its side which runs parallel to the steps are sufficient to support the weight of soil and that there is blatantly insufficient drainage provided. As the side wall which collapsed onto the steps is (was!) the boundry against a public access (the steps) how on earth can them mucking about with this wall itself or doing work on "their" side that clearly impacted on that wall NOT be covered by any building regs???As an example, if you have a tree in your garden but, say, its branches overhang your boundry wall and are above a (public)pavement are you not responsible for maintenance of that tree and would therefore be liable if you failed such "due diligence" and a branch broke off and cracked a member of the public on the head whilst they were using the pavement? Remember, a young 8 year old lad going up these steps at the time the wall gave way was very lucky to escape injury.
