279 articlesPart 16 telecoms masts and the prior approval procedure
A mast notification is not a planning application. The council is deciding two questions, and objections about health or need cannot be taken into account.
Air source heat pumps under Part 14 and the noise condition
Class G of Part 14 makes most domestic air source heat pumps permitted development, but only where the installation meets the MCS planning standard, including its noise limit.
Part 14 solar panels on a dwelling: limits and exclusions
Most domestic solar installations are permitted development under Part 14 of the GPDO. The exceptions are listed buildings, some walls in conservation areas and any array over the size limits.
Part 6 agricultural development and the prior notification
Schedule 2 Part 6 of the GPDO gives farms two different sets of rights depending on the size of the unit. Both need a prior notification before most building work starts.
Part 20 upward extension of blocks of flats
Airspace development on a detached block of flats is permitted development subject to prior approval, but ownership, structure and fire safety decide whether a scheme is deliverable. Here are the limits and the practical gates.
Class ZA demolition and rebuild: the route nobody uses
Class ZA permits demolition and residential rebuild through prior approval, but the replacement is confined to the old footprint and the building must have stood empty for six months. Here is what qualifies and when a full application is better.
Class R: agricultural buildings to flexible commercial use
Class R turns redundant agricultural buildings into storage, offices, shops or workshops through prior approval rather than a planning application. Here are the current limits, the four matters the council can consider, and the trap around Class Q.
Class Q barn conversions: what the current limits allow
Class Q permits an agricultural building to become up to ten dwellings through prior approval. The limits changed in May 2024, and most applications still fail on structural suitability rather than on the numbers.
The larger home extension prior approval and neighbour notice
Up to eight metres for a detached house, six for a semi or terrace. What the notice must contain, who gets consulted, and why silence from neighbours settles it.
Article 2(3) land: what it removes from your allowances
Article 2(3) land covers conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites. Here is exactly which householder rights it removes.
Class E outbuildings and the incidental use test
A garden office usually falls within Class E permitted development. A garden bedroom usually does not. The incidental use test, the height limits and the 50 per cent curtilage rule explained.
Class B roof extensions: the 40 and 50 cubic metre limits
The volume allowance is cumulative, measured against the original roof, and a hip-to-gable can spend most of it before the dormer is drawn. Do the arithmetic first.
Class AA upward extension: what prior approval covers
Adding storeys under Class AA is narrower than it sounds. The date the house was built, the 18-metre cap and the adjoining building rule rule out most sites before design starts.
Original dwellinghouse: the date that decides your allowance
Every Part 1 allowance is measured from the original dwellinghouse, not the house you bought. Extensions built by previous owners come out of your budget.
Class A side extensions: the half-width rule explained
The half-width restriction in Class A catches far more householder schemes than the rear projection limits, and it is the reason most wrap-around extensions need permission.
