A link-detached house occupies an intermediate position in the property classification system between a detached house and a semi-detached house. Understanding the distinction matters because it affects how properties are described in marketing and valuations, and has implications for Party Wall Act obligations and permitted development rights.

What Makes a House Link-Detached

A link-detached house is connected to an adjacent property through a non-habitable structure, most commonly a shared or adjoining garage, a utility room, or a covered link structure. The main habitable body of the house, including all the living rooms, bedrooms, and bathrooms, is separated from the neighbouring house with no shared walls between the living accommodation. Only the lower link structure is shared or touching.

The key distinction from a semi-detached house is that in a semi-detached pair, the habitable rooms share a party wall running the full height of the building. In a link-detached arrangement, only the garage or outbuilding shares a wall; the main house structure on either side is independent.

Why the Distinction Matters

Estate agents and mortgage valuers treat link-detached houses differently from true detached houses. The value difference between a link-detached and a true detached of similar specification is typically modest, but it is worth understanding the status accurately when buying or selling. Some buyers specifically seeking a detached house may reconsider when they discover a link-detached arrangement, while others are entirely happy with it.

Party Wall Act

Where the link structure is a shared or party wall between garages, the Party Wall etc. Act 1996 may apply to any works that affect or are adjacent to that shared structure. If you plan to demolish or alter the linking garage, or carry out work on the wall between the two garages, notifying the adjoining owner under the Act and, where required, agreeing a party wall award is necessary.

Summary

A link-detached house is connected to a neighbouring property through a non-habitable structure such as a garage, while the main habitable body of the house has no shared walls. It is distinct from a semi-detached house, where habitable rooms share a party wall. The Party Wall Act may apply to works affecting any shared or party wall in the link structure. Accurate description as link-detached in marketing avoids buyer misunderstanding.
