Gravesham Borough Council v Secretary of State for the Environment and O’Brien (Michael W) (1984) 47 P&CR 142
Gravesham is a leading planning case on what makes a building a dwellinghouse. The High Court held that the distinctive characteristic is the ability to provide the facilities needed for day-to-day private domestic existence. A building does not stop being a dwellinghouse simply because it is occupied only seasonally, intermittently or by different people.

What Gravesham decided
The case concerned a small building erected under a 1968 permission for a weekend and holiday chalet. A condition prevented human habitation between 1st November and 28th February. The building had a living room, kitchen and bedroom, but no bathroom or internal WC.
An extension was later added. The owner argued that the original chalet was a dwellinghouse and that the extension therefore benefited from permitted development rights under the Town and Country Planning General Development Order 1977. Gravesham Borough Council disagreed and served an enforcement notice.
The Secretary of State ultimately concluded that the chalet was a dwellinghouse. McCullough J upheld that decision. The court’s central point was that whether a building is a dwellinghouse is a question of fact, and that its most distinctive characteristic is its ability to provide the facilities required for day-to-day private domestic existence.
Seasonal occupation did not stop it being a dwellinghouse
The chalet could lawfully be occupied for only eight months of the year and, in practice, was mainly used at weekends and for summer holidays. That did not prevent it from being a dwellinghouse.
The judgment used familiar examples. A second home used only at weekends or during summer can still be a dwellinghouse. A house does not cease to be one because it is temporarily empty, unavailable while being repaired or incapable of occupation for part of the year.
McCullough J therefore rejected the idea that permanent or year-round occupation is an essential characteristic of every dwellinghouse.
Physical character and actual use both matter
Gravesham is sometimes reduced to a single phrase about day-to-day domestic existence, but the judgment is more careful than that. The court accepted that the actual use of a building can be relevant. It also warned that use alone cannot turn any structure into a dwellinghouse. Someone living in a basic office or shed does not necessarily transform the building into a dwellinghouse simply by putting furniture in it.
The assessment is therefore factual. The building’s accommodation and facilities, the quality of the residential use and the wider circumstances all have a part to play. Duration and frequency of occupation may matter in some cases, but they are not automatically decisive.
Why Gravesham still matters
The case arose under the 1977 General Development Order, not the current GPDO, but the courts continue to cite Gravesham when considering the meaning of a dwellinghouse in planning law.
It is particularly useful where a building has residential characteristics but is used seasonally, intermittently or in an unusual way. It can also help when considering whether a building is capable of falling within householder permitted development rights.
However, Gravesham is not a shortcut to deciding that a use must fall within Use Class C3. The planning use of a property remains important, and later cases have emphasised that the physical characteristics of a building and the character of its use may both need to be considered.
