Friggebod

In Sweden, a friggebod is a small shed or cottage which can be built without any planning permission on a lot with a single-family or a duplex house. It is named after Birgit Friggebo, the Minister for Housing in 1979 when the new type of building was approved. The word is a portmanteau of Friggebo and bod 'shed'.
Typical uses for a friggebod are a greenhouse, a workshop, a guest room, or a home spa.

The buildings do not have to follow zoning regulations, but they have to comply with the building code and cannot be built closer to a neighbour's lot than without the neighbour's permission.
