In need of more space, particularly a spare bedroom as family often come to stay. Can't really afford to move as house has been valued at same as 2004 price despite us spending a fair bit to improve it - new kitchen and bathroom etc. We have a detached double garage so the obvious solution is to convert this into a guest bedroom. We live in a conservation area though and are worried that we wouldn't get planning permission - they seem to turn people down if the conversion could lead to a separate extra dwelling. Does anyone have any experience of this or suggestions? Thanks
