I want to build a small building in my garden as a recording studio. I
suppose it's like a kitchen extension but not attached to the house.
I'll use bricks, breeze blocks and soundprrofing insulation in the
However, I want to build it at the back of my garden under the trees.
I know I have to dig up foundations and fill in with concrete. My
question is, can I have foundations without digging? I want to protect
the tree roots. Can I build up a small wall of bricks on the ground
and fill that with concrete to act as the foundations or do
foundations *have* to be underground?

If the floor area is less than 30mē, then it would be exempt from the
Building Regulations, so the depth of the foundations would be
whatever you think is sufficient. If it's over 30mē then you need an
application, and Building Control will want to see adequate
foundations. If you want a building that's not going to start
cracking after the first few weeks, then it needs some foundations
onto something that will bear its weight.
The fact that you want to build it "under the trees" sends alarm bells
ringing. Anything built near trees in any kind of ground could cause
problems, and if the ground is clay, then the foundations need to be
several metres deep to avoid potential shrinkage problems.

Just cos the building is under X sq metres does NOT make it exempt from
building control, It may or may not make it exempt from Planning but that
depends on many other factors. Any structural alteration to your house that
may or may not involve a habitable or "permanent structure certainly would
require to be built under the control of the building control section of the
Mmm. First of all you can get away with cutting thjrough tree roots
without killing teh tree, as long as you ae not TOO close, but you MUST
go deep, as the cutting of teh roots will increase local mosture
content, and, on clay espceailly, give rise to swelling ground - heave.
The most environnatally nice way to do what you want - is expensibve -
and consist in drillng hoes and putting in DEEP plies, and bridging them
with beams of concrete. Youy can then lay a suspended concrete floor
over that lot and leave an air gacp umnderneath. If you don;t want to be
ablke to see under it, you trench a little bit to lay the beams in on
top of teh piles, or backfill later on to raise the ground level.
I'd get a structural engineer in to advise you on teh options.
