Sounds like a spot where an above ground pool was installed, not a
garden... without more information I can't advise what you can/canot
do... but naturally if it's your property you can do whatever you like
so long as it's legal. How large an area are you talking about? How
high above grade is this area? How is this area situated in relation
to the house or other buildings; distance and elevation? A few photos
would help a lot.

Depth 1 ft 3 inch
Length 19 ft 4
Width 11 ft 4

The sheet is located approx 4 inches down and you can see it as a white
colour on the picture. The sheet has also been found by the shed which is
14 ft 6 away from the corner nearest the property.

what is the 1'3" depth describing? depth of
the clay? sand or gravel or ?

the 3" on top is what? topsoil or mulch or ?

does the material let water soak through?

does the entire area drain ok or does
water collect any place? before you put in
a wall and gardens, get the drainage figured
out, that saves a lot of troubles later...

what kinds of things do you want to grow?
any deep rooted plants will not do well
with the barrier. so you have to either
go up or remove the barrier.

if the barrier is in place because of
toxic soil considerations that wouldn't work
very well. any chance this is an old
reclaimed industrial site or waste site?
i don't know the laws in your country and
such about this sort of disclosure by the
seller so...

right now i'd agree with the pool base
hypothesis. might extend it to an abandoned
outbuilding base of some type (perhaps a
greenhouse). this seems the simplest and
most logical answer, but doesn't make sense
for a newly built home... so color me
confused too.
