Specialist foundations will need to be designed and possibly checked by Building Control, yes.

I wouldn’t be put off by a 2.1 m trench dig, but there are risks. What is machine access like to the site?

Thanks noseall. the builder has said the machine access will be fine but has not mentioned what kind of machine. he has measured it though.

 

[noseall]

What machine does that?

3 tonner. Quite bulky.

Digger? Trencher?

Digger? Trencher?

Digger or excavator (in case Woody Is reading).

 

[^woody^]

Diggers not excavators, lorries not trucks, settees not sofas, dinner (not lunch) at dinner time and tea (not dinner) at tea time, red sauce not ketchup and cheese cobs not anything else, if you please.

Thank you noseall. It's just neighbour has a cherry Blossom tree and to ensure roots do not create trouble, the structural engineer has advised a nib of 2.1 meters. I can always ask to re visit the drawings.

2.1m for a cherry tree????? It must be very close to the extension and you must be on highly shrinkable clay! Sounds dubious to me.

 

[Terrywookfit]

Cherry Blossom have most of the roots very close to and on the surface.

They're also prone to disease and early death.

If the tree causes an issue down the line the SE is paying for it. If it doesn't, you are paying for the work to ensure that. Guess which side of caution they will err on!
A good SE and designer can save you more than their fee in these cases

Apart from the cob bit, ( should read, Barm, Woody is spot on )

 

[noseall]

Apart from the cob bit,

One of my favourite snap box fillers is crusty cobs with cheese and onion. Can make a cold rainy day in mud filled trenches seem pleasant.

The crusty but soft and chewy ones? Definitely.

Correct

You can check the depth for certain trees on the nhbc foundation depth app if you want to check the depth they have designed for.
