In Streatham, planning permission may be required for home extensions, depending on the size and nature of the project. For instance, rear extensions exceeding certain dimensions or those affecting the property's appearance may necessitate planning approval. It's advisable to consult with Lambeth Council or a planning professional to determine the specific requirements for your property.
Permitted development rights in Streatham allow homeowners to carry out certain types of building work without the need for a full planning application. These rights are subject to specific limitations and conditions, such as size restrictions and impact on neighboring properties. It's important to ensure that any proposed work complies with these rights to avoid potential enforcement action.
To check if your property in Streatham is subject to Article 4 Directions, you can consult Lambeth Council's planning department or review their online resources. Article 4 Directions remove certain permitted development rights, meaning that planning permission is required for specific types of work that would otherwise be allowed. This includes alterations to the exterior of properties in conservation areas.
A Certificate of Lawful Development in Streatham is a formal confirmation from Lambeth Council that a proposed development or existing use is lawful under planning law. Obtaining this certificate can provide certainty that planning permission is not required for certain types of work, such as small extensions or internal alterations. It's advisable to apply for this certificate before commencing any work to ensure compliance with local planning regulations.
The time it takes to obtain planning permission in Streatham can vary depending on the complexity of the application and the workload of Lambeth Council.
