9183 articlesCar free development and controlled parking zones
The permit exclusion is what makes car free housing enforceable, and it depends on a controlled parking zone. Here is how the mechanism works and where it fails.
Class Q: the building operations actually permitted
Most Class Q refusals turn on the building operations limb rather than the principle of conversion. Here is what the Order permits and how to evidence it.
Fire engineering competence and who signs a strategy
The planning stage fire statement and the engineering fire safety strategy are different documents with different authors. Here is how to check competence and brief the work.
Appealing a refusal or submitting a fresh application
An appeal argues the council was wrong. A revised application accepts the scheme was. Here is how to read a refusal, apply the deadlines and choose between them.
Section 278 highway works: how the cost is built up
A section 278 agreement is six or more separate costs arriving at different times. Here is how each element is calculated and where developers most often underestimate.
Reports needed for a site near an SSSI impact risk zone
Proximity to a Site of Special Scientific Interest does not set the evidence base. The impact risk zone and your development type do. Here is how to check and what to commission.
Condition grading and defect schedules in a structural survey
Condition grading and the defect schedule decide whether a structural survey supports repair, partial retention or demolition. Here is how to build both so they stand up to scrutiny.
Sui generis use: what it means in planning
A sui generis use sits outside every class in the Use Classes Order, so the flexibility that lets a shop become an office does not apply. Here is what that means for your site.
Reports for a site with a Tree Preservation Order
On a site with a Tree Preservation Order the tree survey comes before the layout. Root protection areas are a design constraint, not a drawing added later.
Reports for an extension to a listed building
Two consents, one evidence base. The heritage assessment has to describe significance before the design exists, and recording is expected where fabric is lost.
Reports for 2,500 square metres of Class E floorspace
Two national thresholds land at 2,500 square metres. Because Class E lets an occupier change without permission, the evidence has to cover a range of uses.
Reports triggered when a scheme reaches ten dwellings
Ten units is the threshold where a residential scheme becomes major development. The determination period, publicity and evidence base all change at the same point.
Photomontage methodology in a landscape and visual assessment
Verified views are evidence, not illustration. The survey control, camera specification and registration method decide whether an inspector can rely on them.
Shadow plots and dates in an Overshadowing Study
Shadow plots look simple and are easy to mislead with. The dates chosen, the times shown and what was modelled decide whether the drawings answer the question.
Occupancy profiles in an Overheating Risk Assessment
A dynamic overheating model is driven by its profiles. Bedroom occupancy, equipment gains and night-time window opening change the result more than the glazing spec.
Setting the scope boundary of a Whole Life Carbon Assessment
Two assessments of the same building can differ by a third on scope alone. The modules included, the study period and the elements covered have to be stated up front.
Checking an ecologist's membership and competence
An ecology report is only as good as its author's competence for that survey type. Membership grade, licences and habitat experience are all checkable before appointment.
Odour assessment competence and the methods used
An odour assessment for planning can be a structured qualitative appraisal or a modelled study. The method should follow the risk, and the author's competence should follow the method.
Daylight assessors and the case for independent review
Daylight results depend on the model behind them. Because no accreditation scheme governs the work, authorities increasingly commission independent verification on major schemes.
Fire service vehicle access in a residential layout
Fire access is a building regulations requirement, but it is decided by the site layout. Getting it wrong after permission means redesigning the street, not the house.
Choosing the design vehicle for swept path analysis
Swept path drawings fail when the vehicle is chosen from a software library rather than from the site. Separate regular vehicles from occasional ones and justify both.
Deriving visibility splays from a measured speed survey
Highway officers derive stopping sight distance from observed speeds rather than from the speed limit sign. A frontage survey often produces a shorter, deliverable splay.
Securing something by condition or by planning obligation
Conditions and section 106 obligations do different work. Payments cannot be conditioned, off-site works often can through a negative condition, and the tests differ.
Statement of community involvement: the council's or yours
One document sets the council's own policy on consultation under the 2004 Act. The other reports what an applicant did and what changed. Mixing them up wastes weeks.
