stage 1

1. How to gain the correct approvals needed to build? 


Establish what planning approvals you require first. Full Planning, prior notice consent, and permitted development are the most common types of applications submitted for residential projects. 

Reverse Planning. sounds wired but knowing what you can build without Full planning approval allows for some assurance. Its always a good idea to see if your extension will conform to the requirements set out by permitted development rights, its basically a sure approved design frame work which if followed and the design meets all requirements guarantees approval, find out more. having said this different council interprets the requirement slightly differently so we always recommend that you gain a certificate of lawfulness.


Were a project needs to challenge standard planning policy we recommend researching the area to establish if planning has been granted for a similar development,

We have, in the past used these developments to gain leverage on our applications, gaining permission where planning would've been refused this is known as setting a precedence. a project should be sympathetically designed generally.

​Building regulations

If you plan to create a habitable room then building regulation approval will also be required. In some instances, you may also require additional approvals such as Thames water.


Understanding your neighbors right to light, privacy, bulk and materials will land you in good stead when coming up with a design that meets your needs and fulfills the planning requirement. 

With over 20 years of experience, we could advise on possible design solutions as we have probably encountered it before.
