There are many rules and regulations that will determine whether a home is likely to be granted planning permission, and some requests will be more controversial than others.  A 'pre-app' allows you to ask if a project could get planning permission, and under what conditions, or if it's a definite NO.


The benefit of a pre-app means controversial sites don't pay the whole planning permission price + drawings only to be rejected regardless.  However, if the pre-app is approved, further planning permission drawings and application will still be required.  Our lead designer will be able to advise you at your first meet and greet, but the decision will ultimately be yours.


Rules, known as ‘permitted development’ rights, allow you to extend a house without needing to apply for planning permission if specific limitations and conditions are met.


If you are completely sure your project is permitted development you can start your building work. For proof that your building work is lawful you should apply for a lawful development certificate. If your project does not qualify as permitted development you will need to submit a planning application.


If you want to be certain that the existing use of a building is lawful for planning purposes or that your proposal does not require planning permission, you can apply for a 'Lawful Development Certificate' (LDC).

What is planning permission?  Planning permission details the appearance of a project and the effect it will have on any neighbours.  From whether your neighbours have a reasonable amount of privacy, to whether it is in keeping with the look and feel of that particular street, will have influence whether planning permission is approved.  And any project that does not fall under Permitted Development will be subject to it.  These are a specific set of drawings that are required alongside an application fee and if a project receives approval, it will then be subject to Building Control, below.

At QN Design Architectural Services, our designers have a very good working relationship with planning officers and can guide you as to what is needed to succeed.  In the instance that planning permission is not granted, we will work with you to amend the project or advice you on the next step if their recommendations seem unfair.



After planning permission has been given, a second set of very detailed drawings, including structural calculations, will then be required and a building control application submitted.  Building control details the technical and construction aspects to ensure its safety.  These are the drawings that your builder will work from, thus, a separate set of drawings and a separate application fee is required.  Should you require a structural engineer we can also refer one to you, as well as our preferred builders, thus saving you the time of finding one yourself.
