8778 articlesNutrient neutrality: where the requirement comes from
The requirement sits in regulation 63 of the Habitats Regulations 2017, which sets a certainty standard no amount of housing need can outweigh.
BS 9991 and BS 9999: which fire strategy applies
The residential code and the general code diverge on trading, sprinklers and fire service facilities. Where each applies, and how mixed use schemes are handled.
Daylight and sunlight for schools and healthcare buildings
Non-domestic daylight cases ask two questions at once: performance inside the new building, and loss to a neighbouring school or clinic. The tests differ.
Passivhaus and what certification adds to an application
Certification is a voluntary standard, so it earns weight only where policy asks for the numbers it produces. Here is where it helps and how to condition it safely.
Noise from deliveries and HGV movements at night
Night-time servicing is assessed on short, sharp events rather than averaged levels. What to measure, what to design out, and how hours conditions get written.
A takeaway change of use answered on odour
An illustrative walkthrough of a hot food takeaway change of use, built around the extraction route, the odour control specification and the fan noise evidence.
Replacement windows in an Article 4 area
Where an Article 4 direction withdraws Class A rights, new windows need planning permission. Here is what officers assess and how to evidence the original pattern.
Converting a garage to a habitable room
Internal works are not development and infilling the door usually falls within Class A. The exception that catches people is a condition on the original estate permission requiring the garage to be kept for parking.
Agent of change: building homes next to an existing venue
Bring homes to a venue and the mitigation is yours to design, pay for and maintain. Layout does more than glazing specification, and the maintenance obligation is the part schemes forget.
Decking, raised platforms and the 300 millimetre rule
The 300 millimetre threshold comes from the definition of a raised platform in Part 1 of the GPDO. On a sloping garden a level deck usually crosses it, and the whole structure is caught rather than the high corner.
Small sites and the April 2024 biodiversity commencement
From 2 April 2024 a small site permission carries a biodiversity gain condition, so development cannot begin until the council approves a gain plan. Survey timing is the constraint most self-builders underestimate.
Single staircase residential buildings and the height limit
The second staircase threshold sits at 18 metres, the same height that triggers the fire statement duty and the building safety gateways. Redesigning a consented single stair scheme is usually a section 73 application, not a minor amendment.
Basement lightwells and daylight to habitable rooms
A large window at the bottom of a narrow shaft sees almost no sky. Here is how lightwell geometry governs the result, what else acts on the same opening, and when to reclassify the room.
Embodied carbon and the retrofit against demolition case
Demolition is now a policy question in a growing number of authorities. The answer is a documented options appraisal with whole life carbon results on one study period, not an assertion that the building is beyond repair.
Statutory nuisance and planning: what a condition cannot fix
Two regimes, two tests, two teams. A permitted business can still be served with an abatement notice, and a planning condition cannot reach patrons in the street or a cumulative problem.
Committee referral thresholds and delegated decisions
The scheme of delegation decides whether officers or members determine your application, and the triggers vary sharply between neighbouring councils. Read the constitution before you programme a major scheme.
Annexes: ancillary accommodation or a separate dwelling
An annexe is either part of the same planning unit as the house or a separate dwelling, and the label on the drawing does not decide it. Facilities, access and garden division are what officers weigh.
What changes when the NPPF is re-issued
A Framework revision changes no local plan policy, yet it can transform a case. Here is how renumbering, transitional arrangements and the decision date rule work, and how to update a submitted statement efficiently.
Music breakout from a venue: assessing and controlling it
Music breakout is a low frequency problem solved by a measured criterion, an isolated sound system and an envelope without leaks. Patron dispersal is the part no limiter reaches.
Gateways Two and Three: what happens after permission
Planning permission for a higher-risk building only buys the right to apply for building control approval. Gateway Two is a hard stop before work starts, and Gateway Three governs occupation.
Daylight assessment in dense historic townscapes
In a narrow historic street the existing windows already fall short of the guideline values. Set an alternative benchmark, report against both it and the standard figures, and say plainly where heritage duties limit the design response.
EPC ratings in planning: where they count
The certificate is a cost-based rating for a standard occupancy, not a measure of energy use or carbon. It still governs whether a converted flat can lawfully be let, so model the band at design stage.
Housing land supply and why your site size matters
A shortfall in the five year supply engages the presumption in favour of sustainable development, but the arithmetic is rarely the argument. Test the trajectories, remove named sites with reasons, and match the effort to the scale of the scheme.
Roof pitch and eaves height on a two storey side extension
Class A never permits a two storey side extension, so the roof becomes a design judgement. Align the eaves, drop the ridge, set back at first floor, and draw the relationship properly.
