Notice of Prior Approval
Certain home extensions qualify for Prior Approval under permitted development rules—allowing homeowners to extend their properties without full planning permission, as long as specific criteria are met. We’ve successfully handled hundreds of these applications, creating smart, compliant designs that satisfy local authority requirements.
At Extension Plans, we handle the entire Prior Approval process on your behalf.
With Prior Approval in place, you can move ahead with building knowing your plans meet all necessary requirements.
Your dream home journey begins here!

FAQs
How does the design process work?
Our design process begins with an initial consultation with your dedicated designer. We will discuss your vision, requirements and we will provide ideas for your design based on previously completed projects. From there, we move through conceptual design providing a first draft plan for your consideration. Following this we can revise the plans in any way you like to ensure you a completely happy with the design.
What is the typical timeline for a residential design project?
The timescale of a project differs, depending on the proposal. We can visit your property within a couple of days and have the first draft plans with you in roughly 14 days.
In some cases, building work can begin within a couple of weeks. In others, the timescale can be up to 4 months, depending on your project’s requirements.
