Ancillary buildings – definition and subordination to main dwelling
Ancillary accommodation must be subordinate to and supplementary of the main dwelling's use, providing limited accommodation while sharing facilities such as the kitchen with the host property.
Proposals for ancillary buildings can meet a variety of other personal and domestic circumstances.
