Frequently Asked Questions
How much do planning permission drawings cost?
The cost of planning drawings varies depending on the size, complexity and location of the project.
At HEAMES Architectural Drawings & Planning Consultants, we provide a clear and transparent staged fee structure for typical residential planning projects. Each stage of work is agreed and confirmed before proceeding, ensuring clients have full clarity and control throughout the process.
For a typical house extension planning application, our standard professional fee is:
£1,333.00
Larger or more complex projects such as new build homes, flat conversions or listed buildings may require additional work and will be quoted individually.
Do I need planning permission for an extension?
Some house extensions fall under Permitted Development, meaning formal planning permission may not be required.
However, the process of preparing the drawings and documentation is largely the same, and many homeowners choose to obtain a Lawful Development Certificate for peace of mind.
This certificate confirms that the work is legally permitted and is often requested by solicitors during the sale of a property to ensure the development was carried out lawfully.
We can advise whether your project requires planning permission or permitted development approval.
How long does planning permission take?
Most planning applications are determined within approximately 8 weeks once submitted to the local planning authority (and their fee has been paid).
However, the overall timeline can vary depending on:
-
The complexity of the project
-
Whether the property is within a conservation area or listed building
-
Requests for additional information from the planning officer
Before submission, we prepare the necessary drawings and documents to help ensure the application can be assessed efficiently.
What drawings are required for a planning application?
Most planning applications require a set of existing and proposed architectural drawings, including:
-
Existing floor plans
-
Proposed floor plans
-
Elevations (front, rear and side views)
-
Site plan and location plan
These drawings must be accurate and drawn to scale so that the planning authority can properly assess the proposal.
