What is the difference between a party wall and a boundary wall?
A party wall either separates buildings, or is built astride the boundary and forms part of a building.
A party fence wall stands astride the boundary but does not form part of a building. A garden wall is described as a Party Fence Wall if sits on the boundary and separates two owners’ land. If a Building Owner wishes to undertake work to a Party Fence Wall then notice should be served in the same way as if works were to a Party Wall.
A boundary wall does not form part of a building, and does not stand astride the boundary but on one person’s land or the others.
