I have an old chimney breast in my bedroom. My room is fairly big but it's getting smaller because all of my space is being used up by wardrobes and shelves. I was considering knocking through the wall of the chimney breast and having a walk in wardrobe. We do have a fire place below but it's a gas fire, so others have said that ventilation shouldn't be a problem. My partner doesn't want me to do it though because they think it'll be too much money and too much work. Please help.
