Hi. We live in the country and have a four-bedroom cottage with a double garage. We share the house with my 85-year-old mother, who is finding the stairs very difficult. We would like to convert the attatched garage into a ground-floor granny annex for her and build a new double garage. Has anyone done anything like this? How would planners see it? We have only two neighbours, both of which have recently extended their cottages and built large double garages. Would that help our case?
