We are desperate for more space. 2 bed house.....kids sharing a room but need their own. We cant afford a 3 bed in this are so thought about turning the living room into a third bedroom and putting a single story extension/solid wall and roof conservatory on the back of the house to give us back living space. There is no option to do a loft conversion and we are mid terrace so our only option is to go out at the back. The drawback is that I can't see how we would do it without meaning that the new bedrooms only source of light would be looking out into the new extension......or failing that carving the garden in half.
