SWMBO wants a utility room and the only way to do this is to re-instate what
was a lean-to kitchen.
raising the concrete floor and erecting an end wall is simple enough but
what to make the roof with ?
the fall will be fairly shallow, 100mm over 3000mm, so I was thinking of
putting up a translucent polycarbonate roof... either the double skin flat
stuff or corrugated.
is there an online source for info on erecting that type of roof, what
components I'll need etc. ?

thanks
