Planning application
PL/10239
8 Heol Treventy, Cross Hands, Llanelli, SA14 6TE
Proposal
We consider that a Lawful Development Certificate should be granted for this proposal because the works fall within permitted development rights, under Schedule 2 Part 1, Class B of the GPDO. The property is a lawful single dwellinghouse with no known restrictions on its permitted development rights. The proposed loft extension, which includes a rear-facing dormer to facilitate an additional bedroom, complies with all relevant criteria: it does not exceed the height of the existing roof ridge, remains within the allowable volume increase, is set back appropriately from the eaves, uses materials of similar appearance, and does not include any balconies or raised platforms. The proposal does not involve a change of use and solely enhances internal accommodation. As such, the development is lawful and planning permission is not required

What a grant of permission means
The process from here
Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.
Work must normally begin within five years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.
About lawful development applications
How this application type works
A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.
