    Hello all,

    Neighbour and I have a garden(boundary?) wall between us that we are looking to raise by two blocks for privacy.

    Currently, it's 7 blocks high (possibly 8 but the from that would be beneath the soil surface) standing at about 1.5m . It's made of single leaf 100mm blocks with piers every 3-4 metres or so.

    Are there any concerns with adding two additional rows of blocks, including adding to piers?

    Thanks

    From a Planning point of view, stay below 2m.
    From a support point of view, maintain the joints and extend the piers also.

    I added 3 blocks of the same build up as yours, and then added a flat fibreglass roof and all ok.

    You sure it's 100mm block ? You certainly wouldn't build a circa 2m high block wall in 100mm from the start, would nearly always 215mm hollow. I appreciate that's not the space you are in but I wouldn't be keen. I've added on to our own boundary walls but there are 215mm wide. Maybe lots of piers will help, not sure if 4m ctrs enough ?

    Nearly every boundary wall built from block here in Dublin was 100mm on the edge with piers every 4m.

    Fair enough but you won't get an engineer now to say it's ok at 2m high. 1.5m maybe but I'd say that's pushing it.
