Do I need planning permission?
In many cases, you can extend or alter your home without applying for planning permission—as long as your project meets specific Permitted Development criteria. These criteria restrict the size, position, and proximity to boundaries, and consider how the project might affect neighbouring properties.
During your initial consultation, we’ll explain all relevant planning requirements, so you understand exactly what’s needed from the start.
Why are plans important?
-
You must include plans with any planning application, as they give the local authority an accurate representation of your proposed works. We provide all the necessary documents, including:
-
Scaled floor plans, elevations, and sections
-
Detailed specifications to guide construction
-
Documents prepared for submission to local planning or building control authorities
By producing detailed plans early, you:
-
Maintain greater control over your design and layout
-
Improve cost control by allowing accurate quotes from multiple builders
-
Gain the option of full project management, where we oversee the entire build and appoint trusted contractors
-
Do I need building regulations approval?
Yes—homeowners typically need to get building regulations approval for:
-
Home extensions
-
Loft, garage, or basement conversions
-
Structural changes (e.g. removing load-bearing walls)
This process requires a detailed technical submission that explains how you’ll construct the building to meet safety and performance standards. The council will inspect your project at key stages to ensure compliance.
As a bonus, Millhouses Design Limited works in partnership with Sheffield Building Control. This agreement helps us streamline and speed up the approval process for our clients.
The video below highlights some of the key points.
How long will it take to produce plans and gain approvals?
The process of gaining planning and building regulations approval can usually be completed within a twelve week period. Once complete your chosen builder will then be able to start work.
Are there any additional costs?
Yes—there are statutory fees payable to the local council for:
-
Planning applications
-
Building regulations submissions
These fees depend on the scope and size of your project. In more complex cases, advice from a structural engineer may be required. We’ll provide a breakdown of all expected costs during your initial consultation.
