Permitted Development Applications
Permitted Development Services
You can undertake certain types of work without applying for planning permission. These are known as “permitted development rights”. They stem from a government-approved general planning permission rather than from local government.
Make sure you distinguish between common house projects and flats, maisonettes and other buildings that are not permitted for development. Commercial properties also have different permitted development rights to houses.

*Some examples of how you can extend your home within the permitted development rights
Single storey rear extensions
Extensions up to 3m in depth (4m for detached properties).
Loft conversions
Up to 40 cubic meters for erraced properties or 50 cubic meters for any other properties.
Single storey rear extensions
Extentions up to 6m in depth (8m for detached properties).
Single storey side extensions
Up to half the width of the original dwelling house.
Outbuildings in rear gardens
Please contact your local planning authority if you are unsure if your planned building falls into the ‘outbuildings’ category
First floor rear extensions
Subject to planning requirements.

Customers Reviews
I am an Architect and have worked with Ben on many projects. All of them have gone without a hitch with Ben designing out any issues on paper so the construction has gone as smoothly as possible.
After having worked with dozens if not 100's of structural engineers in the past 25 years of practice Ben is the one I would choose to work with on my own home.

They were happy to travel out to France to survey and opine on a bendy cellar wall, cellar wall issue now sorted after some great advice that saved thousands of pounds worth of potentially wasted work
