Conversion of garages and outbuildings to ancillary residential use Q & A DCP Section 10.4
This sub-section is concerned with instances where it is proposed to convert integral garages and outbuildings at existing dwellings into ancillary living accommodation such as an extra living room or bedroom. As described below there is no material change of use involved in so doing, but as many planning permissions for housing embody a condition safeguarding against such an eventuality, there are a considerable number of applications and appeals relating. Conventional contentions relate to the loss of parking space at the dwelling concerned and possible effects on highway safety or amenity. The scenario where separate and self-contained accommodation such as granny annexes is created in residential outbuildings, including garages, has already been described at 10.2).
