Building near TPO trees

[MrJuice]

I'm considering building a classroom at the back of the garden for my son who has autism

Back of the garden has an enormous TPO tree and there's another about 15 metres away

I'm thinking something new age that will be quick to construct. I've seen various piling type foundations used on grand designs but never paid attention to exactly what they are and why they're uses

What building options would the ph massive suggest?

Width is approx 9 metres I think. Possibly 11. To get a decent depth, it'll be going through planning I think

Cool, noted

Thank you

Not without permission, that is...

Actually, the offence is to willfully damage or destroy the tree, so they'd have to prove that increasing the ground load (or other activity) had done damage.

But it's a risky/stupid thing to do, without the necessary permission.

LPA Tree Officers are quite frequently more helpful and pragmatic than you might imagine, though, so can be worth having a chat to them.

Can't believe how long this is all taking.

But anyway, tree officer was indeed very helpful and pragmatic. There's only one for the whole local authority and so I sent her pictures, scaled drawings and written descriptions of what I want to do to help.

She agreed that beam and block construction of a 30sqm outbuilding within the root protection area of three TPOd trees would be okay. The building would be at least 6-8 metres from each tree.

Just waiting for party wall agreements and should be cracking on in a few weeks.
