Need to replant new trees on the boundary that won’t interfere with house foundations

[EvangelicalAboutButteredToast]

Any advice?

We are having some large established trees taken out and are planning to replace with screening trees that won’t develop the root system that will damage the foundations of the house that’s a couple of metres from the boundary line.

A Google of the types of trees gives me this sort of thing https://kingco.co.uk/top-10-screening-trees/

It’s a North facing garden with clay soil. It does get decent sunlight. The house only has a small bathroom window in that side so blocking light isn’t an issue. I rather like the pleached trees that have a lot of trunk showing and then a ball of foliage at the top. They look lovely, but I assume need a lot of tending 🥴

Pleached trees don’t have a “ball” of foliage (that would be a standard), they have a purely two dimensional fan of foliage. So they’ll need annual pruning of branches which decide to break out into 3-d.

Have you thought about fruit trees grafted onto dwarfing root stock. Many grow to 3 m tall or can be smaller and narrower depending on early pruning, which is enough height over a 2m fence, can get a tasty a fruit crop- only issue with this if planted too near fence fruit can drop onto neighbours side.
spend some time on looking at suitable ‘ root stock’ as the same breed of apple tree for example can be grafted on a different stem which will effect the end high and spread for tree. Specialist nurseries will supply these options.

Also get lovely blossom from fruit trees.

Can also consider using massive pots if concerned about house foundations and also can give more height.

Also consider, if it’s for privacy, what cover you need for winter. We looked at a combination of beech, photinia, rowan and hawthorn as standards for along a fence. They are expensive at that size though (1.8m stem).

Yep, I was going to say similar to @MereDintofPandiculation - less of a "ball" and more of a 2D hedge in the air. They do look really smart though. Agree with @owlsinthedaylight, if you're going for screening, defo go for evergreens. I live in a new build and the gardens are overlooked, lots of people around here have the Red Robins. Good choice of pleached trees on here: https://justpleachy.co.uk xx
