Ancillary accommodation – be it a ‘granny flat’ within the main home or a separate guest cottage – can be an invaluable asset.

As multi-generational living continues to rise, a separate dwelling can give both elderly relatives and adult children unable to afford a place of their own the independence they need, as well as family support when they need it. And there are advantages for primary residents, too, including shared bills, free childcare and someone feed to the dog when they’re away.

Even if you don’t have family members to accommodate, having a private, self-contained space for occasional guests or as a source of rental income can be a real advantage. To inspire you, here is a selection of some of the best ancillary accommodation on the market.
