were keen on a house buy its v dark....it has leaded windows all around , and for swine reason the owners have added I an eight metre porch also with leaded windows which means that the lounge is so dark that even today the lounge needs a light on!! scared of committing in case removing the I met wall and changing windows won't be enough....does anybody have any experience of replacing leaded glass to increase light access, or of adding light holes(?) To draw in sunshine? Hate a dark house...
