Maisonette Outbuilding Planning Permission

[MrBSouthcoast]

The Leaseholder for the downstairs Maisonette wants a Outbuilding built in their small garden (4.5m wide, 2m deep and 2.5m high. Using Screw pile foundations). They have informed me they 'phoned the local Planning Dept and were told that the property will have Permitted Development Rights and that they don't need planning permission - is this correct?

[Tipper]

I know flats don't have permitted development rights, not sure about other shared buildings such as maisonettes.

What is considered an outbuilding?

A structure not connected with the primary residence on a parcel of property. This may include a shed, garage, barn, cabana, pool house, or cottage.

First find out what will be erected.

A maisonette is most definitely a flat and as such there are no permitted development rights other than some minor operations such as erecting walls or fences.

An outbuilding can only be erected under PD right on land within the curtilage of a dwellinghouse.
That excludes all land demised with a maisonette.

I would call the local planning office and see what they say

The planning regime for flats and maisonettes differs in many important ways to that which covers houses.
Bear in mind that the permitted development rights which apply to many common projects for houses do not apply to flats.

The first quote was from a director of a planning consultancy company, while the second quote is from the Planning Portal web-site, but of course you can call the local planning office and "hear" what they say.

Alternatively look at the Interpretation section of the Town and Country Planning (General Permitted Development) (England) Order 2015 to read the definition of dwellinghouse.

“dwellinghouse”, except in Part 3 of Schedule 2 to this Order (changes of use), does not include a building containing one or more flats, or a flat contained within such a building;
