The neighbour is not admitting fault to his raised garden causing my wall to fall. He is now saying he will built his own wall ( in his own garden). The question is he is on the higher part of the hill and if he builds a wall up to 2 metres high then it will actually be 3 metres high on our side ( as we our in the lower part of the hill and his garden is about 1 metres high on higher). Further when we build our wall back which can only be 2 metres with planning permission- it will look odd. Can the neighbours do this and what can I do. Also there would be an issue of light in my garden ( already effected when they built the neighbours new house). Should the neighbour inform me of details of his wall as he is building near my boundary? Is he allowed to build 2 metres wall on his raised garden level as I have read somewhere it should be from the original garden level? Also he does not build a retaining wall to hold his garden back then any future wall I build will actually be as a retaining wall that he can use to support his garden which is unfair as he does not want to pay for my wall that he has damaged?

So you mean an extension of our brick wall which thickens on the neighbours garden side ( under his soil) as it goes deeper into the soil. Problem is this would not be reinforced as the neighbours reinforced hollow brick will be. Also a brick wall built this way would mean a) it’s our whole wall going into his border which I am not sure he would agree b) the brick wall can’t be reinforced ( and the horizontal pressure from the neighbours garden against our wall, especially when the soil is wet from heavy rain and water coming downhill generally as we live on a hill, is high. Our double brick wall has cracked from the middle to to horizontal pressure c) we might have problems accessing the neighbours garden in the future for repairs. d) the neighbours only want about 215 mm of the side of their garden dug to accommodate a hollow brick wall and drainage gravel behind it.

The neighbour can’t refuse to take part as it is his garden which is sliding downhill and pushed our wall down. His garden weight has increased as it has been ‘built up’ from the old original house that was knocked down’s level without considering the effect on our wall. Also he has built his patio right against our wall which is pushing our wall down. His whole garden patio plus soil area is dropping vertically and moving downhill horizontally so to be frank he would be responsible for ‘ securing’ his garden so it does not damage other people’s property. Hence the second wall on the bright side to retain his garden and stop it sliding. Our brick wall is on our borderline originally built like that so we wanted it built the same. Otherwise our borderline will change.

Here are some more pictures. The neighbours garden is sliding towards our wall. The soil is built up with old rubbish from when they knocked down the old house and dig a basement in the new house. They also rebuilt their patio right against our wall. There will is approximately 15metres by 1 metre high and then pillars which are 550mm x 1 metre.

See pictures. The existing brick wall is on the border and is our wall on our land. We are excavating the existing wall. Then rebuilding as original. Then there will be a reinforced hollow concrete filled wall on the neighbours side up to his soil level as he needs to stop his garden from pushing our wall down again. His garden is 1 metre higher than ours. There will be a joint concrete foundation which will cross into the neighbours garden plus ours to build both walls on. Planning the foundation to be 800mm deep and about about 750mm wide.

Hi I just need some advice. We are building two retaining walls as the neighbours garden is sliding and pushed our wall down. We are on a hill and our garden is lower than the neighbours. One wall will be the original double brick wall with pillars (16m x 1m and then 1 metre high pillars with wood panels) on our border and then there will be a reinforced hollow concrete block wall filled with concrete on the neighbours side of the garden ( up to his soil level), to ‘retain’ his garden and stop his garden sliding down and pushing our wall down. Does anyone know how much gap needs to be left in between the two walls?
