FAQ's
Not always. Some house extensions can be built under Permitted Development rights without a full planning application, provided they meet specific size, height, position and other requirements. Larger extensions or proposals outside these limits will normally require planning permission. Restrictions can also apply to certain properties and locations. Melrose Designs can assess your proposed extension and advise on the appropriate route before drawings are submitted.
Most house extensions need to comply with Building Regulations, even where planning permission is not required. Building Regulations cover areas including structural safety, insulation, fire safety, ventilation and drainage. Detailed drawings and specifications provide Building Control and your builder with the technical information needed to demonstrate how the extension will comply.
Planning permission deals mainly with whether a development is acceptable in planning terms, including its size, appearance, location and impact on neighbouring properties and the surrounding area. Building Regulations deal with how the work is designed and constructed, including structural safety, fire safety, insulation, ventilation and drainage. They are separate processes, and an extension may require one, both, or in some circumstances neither.
Yes, in most cases. Removing a load-bearing wall normally requires a new beam or other structural support to safely carry the loads above. Structural calculations are used to determine the required beam size and check its supports, and these are normally submitted to Building Control as part of the Building Regulations process. Melrose Designs can coordinate the structural design alongside the Building Regulations drawings.
The cost depends on the size and complexity of the project and which services you require. Melrose Designs offers architectural and extension drawing services from £350, with a clear quotation provided before work begins. Additional services such as site surveys, planning applications, Building Regulations drawings and structural calculations can be included depending on your project.
For a straightforward householder application, around 8 weeks is a typical statutory determination period, although the actual timescale can vary depending on the proposal, validation requirements and whether the council requires further information or amendments. We manage the application and liaise with the local authority throughout the process.
Yes. Melrose Designs can act as your agent, preparing and submitting the planning application and dealing with Wigan Council during the application process. If the planning officer requests further information or amendments, we can review the request, discuss the options with you and respond on your behalf.
