I am looking to move my sanctum and therefor lab out into the forrest. To this end I need to get a suitable location I had the following idea:

1 make a tree grow realy realy big, large enough to hold my sancta within it.
2 reshape the tree so that a large space is opened within it to use as labroom.

For step 1 I am thinking I will need an item to constantly keep a tree under the effects of a spell increasing its size.

The effect would be:
Ancient Heart of the Forrest (MuHe 25)
R:Touch, D:Sun, T:Individual
This spell causes a tree to grow to its normal size +4.
(Base 3, +3 additional size increases, +1 touch, + 2 Sun)

The item's effect total would be 25 (spell effect) + 1 (2 uses per day) + 3 (enviromental trigger) = 29. The item itself will most likely be a small gem that I place within the tree itself via a MuHe 20 effect to make the wood malable (base 3, +1 touch, +2 sun, 2 size) This effect would also allow me to sculpt out a hollow area for the lab within the tree.

That depends on the tree. An American sequoia could easily contain enough space for a laboratory. Obviously, those aren't native to Mythic Europe, but a European chestnut tree or a fused grove of chestnuts could contain 500 sq. feet (the minimum lab space from 5th ed.) just as easily.

Creo will bring something to maturity, but the tree in question is already mature, and simply still growing. The fact that Rego allows you to make a plant bloom and bear fruit out of season led me to believe that it would control the life cycle within the mature stage, although I did mention a Creo requisite. Rego would definitely be used to make the growth shape a lab space out of the trunk, though, so maybe the casting technique and the requisite would be reversed.

If that trunksize is natural for those trees, then by all means...

As long as it is growing, creo works. A Rego requesite would be required to make it grow as you directed however. If done like this, it could be cast as a spell instead of enchanted into an item as there is notthing unnatural about it.

That whole "fused grove" is IMHO the way to go. Some trees,
grown tightly together, will "fuse" their trunks as they press
upon one another, making what is essentially a "wider" trunk.

With this in mind, I would lay out a "floorplan" and plant
trees along the lines of walls/etc. Plant the trees, then
grow 'em.

Then, plant "interior wall" trees, either Rego'ed to be taller
& thinner, or naturally of a taller/thinner kind.

Rego should be able to weave branches/twigs/leaves to a pretty
solid roof.
