Permitted Development
Permitted development rules let homeowners extend their homes without full planning permission—provided certain conditions are met. We’ve delivered hundreds of projects within these guidelines, creating great designs that meet local council requirements.
At Extension Plans, we take care of the necessary applications and manage the process from start to finish.
In many cases, our clients can go straight into construction without waiting for formal approval, helping the project move forward without delays.
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.
