Think about a separate room or small outbuilding to store seldom used items or put things like an air compressor that make a lot of noise.
I agree with the compressor having its own room. Maybe my compressor is louder than most, or maybe I'm getting too old, but my air compressor really drives me nuts.
I dont put anything in a non insulated area if I
want to keep it from rusting.. I put my 38 ply in
the pole barn one winter.. it was starting to rust
in just 6 months.. with the heated floors my shop
is dry all the time.. even if I spill water on the
floor and the 38 is fine now.. I keep stuff out in
the pole barn like my zero turn and other things
(its not insulated or heated... also you never have
enough lights... last year I ran 2 more strings of
some high output halogens.. also on the ceiling I
have reflective material thats also insulation(not
much but it all helps.. it cost me $30-$35 a month
to keep it at 62*.. any warmer and I'll sweat with
that style of heating and I just wear T-shirts
EDIT
Also I have my compressor in the shop.. its not that
noisy but the air is much drier.. I only have to drain
it monthly plus I run driers on the air lines and they
all go up then spread out and each drop has a drain..
I have painted a couple of cars in there but I hate
to do it now days(to much to clean up)
