Is there any reason not to use ttreated C16 timber to construct my shed
given that is only very slightly mor expensive than the non-treated stuff?

Also I'm using a layer of blocks at the base with a dpm between that and
the first timber. Should I fix the timber through the membrane to the
the block of just let the shed sit on the blockwork? Fixing seems
preferable but will bridge the dmp.

thanks again

I was about to ask why you wanted to use 500-year old wood. I'm glad I
Googled and didn't! ;-)

My approach with shed building - yes now 4 - is to build the wooden
part off a single layer of concrete blocks. The 8 inch height is
adequate in my experience to lay the dpm and not give bother with
dampness tracking through the fixing bolts. I continue the shed
cladding down the blocks using screws and the plastic spacers you get
from Screwfix - keeps the rain off the blocks and creates a
ventilation gap.

One shed was a rebuild and had a floor with no dpm and the block wall
off that - the others have a dpm under the floor only and a block wall
from a concrete found.

The advice I was given by a builder was not to use a plastic dpm but
use a good bed of silicon in this application - the reason given was
that the silicon will never cause any puddling if there is any
moisture ingress.

Did exactly that with the base. But I did make some u shaped brackets to go over the bottom timber and attach to the brick work to hold the shed down in a storm.
