Not sure whether your project needs planning permission? Five questions about your house and your project, and you see whether it is permitted development and the fixed from-price.

The project at Sebright Rd High Barnet included remodeling rear of the property to make the kitchen much larger and to add the kitchen island, dining area to sit down with family as well as home office towards the front of the house and lastly adding a new large bathroom with extra storage on the ground floor.


As follows we will look at the project from start of the construction to finish of the project.


Below is a video of the actual project step by step please watch the video:

Can it be done under permitted development?

A single-storey rear extension of 3 m on a terrace or semi (4 m on a detached house), a side-return infill and a side extension up to half the original width are permitted development on a house outside a conservation area or Article 4 street — no planning application, just a Lawful Development Certificate, which we apply for on every one. Fixed-price permitted development extensions start from £42,000 inc. VAT (£35,000 + VAT) at economy specification, design and build inclusive, and the 6 m / 8 m larger home extension goes through a 42-day prior approval notification rather than a full application. See our permitted development projects page for every product with its from-price and the checks we run before we confirm a project qualifies.
