willbish Posted October 18, 2019 Share Posted October 18, 2019 Should I be concerned about the 5ft trees my neighbour has planted just the other side of my boundary? He's planted a row of mixed Hawthorne varieties the closest being 5.0m away from my raft. The ground condition is pretty poor here, the raft is 300mm thick throughout with significant reinforcement. I'm reluctant to rock the apple cart with the neighbour; we have a tolerable relationship! Im also reluctant to start asking questions of the raft designer. NHBC guidance seems to make reference to existing trees when designing rafts but doesn't mention or recommend minimum safe distances for new planting.

Temp Posted October 18, 2019 Share Posted October 18, 2019 Personally I wouldn't worry. In any case you can't stop him planting the trees. I suppose you could dig a trench and insert a root barrier - that would be easier now than later. I believe you are allowed to cut tree roots if they cross your boundary (in say 10 years time) but not to the extent they kill the tree. Link to comment Share on other sites More sharing options...
Oz07 Posted October 18, 2019 Share Posted October 18, 2019 You can't really control what happens other side of boundary. Temp makes good suggestion. They would always be liable for any damage however your insurance premiums could rise slightly when you have to start declaring tree Link to comment Share on other sites More sharing options...
PeterW Posted October 18, 2019 Share Posted October 18, 2019 I would drop a root barrier in now on your side of the boundary about 12” in from the row. It will stop any roots drawing water from your side too in the even you want to plant up that side. Link to comment Share on other sites More sharing options...
Jilly Posted October 18, 2019 Share Posted October 18, 2019 Hawthorn trees have a surprisingly high water demand, so would second the root barrier idea. Link to comment Share on other sites More sharing options...
Ferdinand Posted October 18, 2019 Share Posted October 18, 2019 (edited) Hawthorn will taek a long time to become significantly large, so imo either do nothing or the root barrier. Edited October 18, 2019 by Ferdinand Link to comment Share on other sites More sharing options...
Mr Punter Posted October 18, 2019 Share Posted October 18, 2019 When you do the tree assessment for foundation design it assumes the tree is fully grown, even if it is currently a sapling. Mainly it shrinkable clay soil that will be an issue. Link to comment Share on other sites More sharing options...
willbish Posted October 18, 2019 Author Share Posted October 18, 2019 Thanks for your replies. The stone wall on the boundary is to be taken down and rebuilt so when this happens I'll put a root barrier under the footing. It's a shame he's planted them now because it's going make rebuilding the wall more difficult when the time comes. Link to comment Share on other sites More sharing options...
