It is the shadow of the N hill that concerns me in that respect. As
it
is nearly the longest day now it is hard to judge what the sunlight
will
be like nearer the shortest day.
Many years ago I bought a book from the CSIRO called, I think,
"Sunshine and
shadow in Australia" and by using a protractor included in the back
of the
book, I was able to work out how much sun I would get through each
window
from any particular angle. I don't know if its still available and
unfortunately I can't find it at the moment to make sure these details
are
true. Basically it gave directions, based on your latitude, of how
much sun
to expect based on the aspect of the window and also showed what sort
of
awning to provide in order to let in winter sun and keep out summer.
You
may have to take a sight over the top of the hill from where you
imagine
your north wall will be and then measure the angle to see how much
sun, if
any you will lose.
Just did a "Google" search and I found it here, along with some other
interesting books

Its the 4th from the bottom.
Good luck

Great! It is still in print. This will save me doing lots of sums.
