279 articlesClass ZA: demolishing a building and rebuilding as homes
Class ZA of Schedule 2 Part 20 covers demolition of a qualifying detached building and its replacement with flats or a single dwelling, under prior approval rather than a full application.
Air source heat pumps under Part 14 Class G
Class G of Part 14 covers domestic air source heat pumps. The volume limit, the noise assessment installers skip, and the conservation area and listed building traps.
Part 14 Class J: solar on non-domestic roofs
Commercial rooftop solar runs through Class J of Part 14, with a prior approval on design and glare. The dimensional limits, the glare study and the substation nobody budgets for.
Solar panels on houses: Part 14 Classes A and B
Class A covers panels on a roof, Class B a stand-alone array in the garden. The dimensional limits, the two standing conditions and where listed building consent still bites.
Part 11 Class B: prior approval for demolition
Demolition is development. Class B gives a permitted right subject to prior approval of method and restoration, and it stops at the conservation area boundary.
Part 6: agricultural development on units of 5 hectares or more
Agricultural permitted development is generous and hedged with conditions. Here are the area, height and proximity limits, and how the prior notification actually works.
The 28 day rule: temporary use of land under Part 4
The 28 day rule is more limited than its reputation. It excludes buildings and their curtilage, caps some uses at 14 days, and counts days across the whole planning unit.
Class Q after the 2024 changes: barns to dwellings
The 2024 amendment reshaped Class Q. Here are the unit and floorspace limits, the building operations you can and cannot carry out, and the exclusions that still bite.
Class G: converting upper floors over shops to flats
Class G keeps the commercial unit and puts up to two flats above it, under prior approval rather than a full application. What it allows, and where it stops.
Satellite dishes and antennas under Class H
Two dishes on a house under 15 metres, within size limits, sited to minimise their appearance, and removed when no longer needed. That is Class H in a sentence.
Flues, chimneys and soil vent pipes under Class G
A wood burner flue is usually permitted development, and the two limits that decide it are the one metre height rule and where the flue sits on a protected building.
Porches under Class D: the 3 square metre and 3 metre rules
Three numbers decide whether a porch needs planning permission, and the one that catches people is the two metre standoff from the boundary with a highway.
Class MA prior approval: the vacancy and floorspace tests
The two-year Class E use condition is now the test that decides most Class MA applications. Here is how the vacancy and floorspace conditions changed, and what evidence proves the use history.
Class C rooflights and the 150 mm projection rule
The 150 mm limit is measured perpendicular to the roof slope, not vertically. What Class C covers, the height rule, the obscure glazing condition and the escape window conflict.
Class AA: adding storeys to a house under prior approval
Check the construction date, the designation and the height arithmetic before drawing anything. What Class AA allows, the houses it rules out, and the amenity grounds that cause refusals.
Permitted development removed by a planning condition
A condition on your permission can remove householder permitted development rights for good. How article 3(4) works, when a council can justify it, and the section 73 route out.
Permitted development on a flat, maisonette or converted house
A building containing flats loses Part 1 permitted development rights entirely. The horizontal division test, the Classes that still apply to blocks of flats, and how to get certainty.
Conditions on permitted development you can still breach
Meeting the size limits is only half of permitted development. The conditions attached to each class are where extensions quietly become unauthorised development.
Part 7 Class A: extending a shop or a Class E unit
Class A of Part 7 allows a shop to be extended by 50 square metres or 25 per cent of the original building, whichever is less. Where the right applies, and where it does not.
Class D porches: the three limits that decide it
A porch is permitted development if it stays under 3 square metres, under 3 metres high and more than 2 metres from a highway boundary. How each limit is measured and where the right does not apply.
Class F hard surfaces and the permeable paving condition
Class F allows hard surfacing, with a drainage condition at the front and none at the rear. The five square metre rule, porous options and the crossover consent.
Evidencing permitted development for a proposed works certificate
Section 192 certificates are decided on the drawings, not the merits. What to submit, how to prove the original dwellinghouse, and why it matters at sale.
Article 4 directions: how they are made and challenged
There is no appeal against an Article 4 direction. Your influence sits in the consultation window, in the evidence base, and in the twelve month compensation rule.
Prior approval: what the council can actually refuse on
A prior approval is not a soft planning application. The council can only consider the matters its class lists, and everything else is outside its remit.
