Conservatories can be exempt from building regulations if they meet specific criteria. Here’s exactly when the exemption applies and what happens when it doesn’t.
Conservatories are usually permitted development — treated as a rear extension. Here are the size limits, exceptions, and when planning permission is required.
Article 4 Directions can remove Class A, B, C, E, L, Q and other PD rights. Here’s which rights are commonly removed, what triggers an A4D, and what to do if one applies to you.
Conservation area Article 4 Directions remove additional PD rights beyond the standard conservation area restrictions — often extensions, roof alterations, and outbuildings.
Planning conditions must be complied with before, during, or after development. Here’s how to discharge pre-commencement conditions, fees, and what happens if you breach them.
Householder planning applications take 8 weeks; major applications 13 weeks. Here’s what affects decision times, what to do if the LPA is late, and realistic timescales.
