Depending on the size, location and design of your extension, you may need to follow permitted development rules, obtain planning permission, and comply with Building Regulations. We manage all of this for you.
Many extensions can be carried out under permitted development rights — typically when:
Even where permission isn’t required, we recommend a Lawful Development Certificate to confirm compliance and avoid disputes when selling.
Required for larger or more complex extensions, or where permitted development doesn’t apply. You will usually need permission if:
We prepare the drawings and site plans, submit the application and liaise with Manchester City Council on your behalf.
All extensions must comply with Building Regulations, regardless of planning. They cover:
An approved building control inspector assesses the work at key stages — final certification is issued once the project is completed correctly.
Choosing the right contractor is essential for a smooth, stress-free experience and a high-quality finish. We provide a complete, professional service from initial idea to final completion — with full transparency and reliability.
We manage the entire process — design, structural planning, construction and finishing. One team throughout the project means better communication, fewer delays and consistent quality from start to finish.
You receive a detailed quotation before work begins, so you know exactly what you are paying for — and any necessary variation is explained and approved before additional work is undertaken.
We take care of the entire planning process on your behalf — drawings, submissions and communication with Manchester planning authorities — helping to improve approval success.
All construction work is completed to meet UK Building Regulations and fully certified on completion via building control. We work with qualified professionals for structural safety, energy efficiency and lasting build quality.
