Single Storey Extension Planning Permission

and Building Regulations Design

The addition of a single storey extension can add significant value to your home, and help you turn your house into the home you've always wanted. A single storey extension can be designed to be:

A kitchen extension
A utility room
A new reception room
A sun room
A home cinema room
A Playroom
A study

We can design your single storey extension to be anything you decide. We can take care of the Local Authority Planning Permission and Building Regulations for you, so all you have to do is select your builder.

 

Testimonials and Design Samples

"We needed a low cost set of plans for our extension and garage conversion. We found Extension Design Plans on the internet and were very impressed with our initial telephone conversation, so we booked them in for a one-day service".

"The morning was very helpful for us to bounce ideas around with the architect at our home. The plans were finished and submitted the same day. We're very impressed and the Council approvals came through quickly as well".

Please contact us to find out more about our services and how we might help with your project.

How long does the design process take?

We are able to call out to your property for our one day design process. We are able to measure your property and sit with you whilst we design the extension in front of you.

These are not final plans and we will still need to complete the building regulations drawings.

We aim to get the design finalised plans and a copy is then sent through to you to agree. We then submit the relevant council applications and plans.

Why are your fees less than I have been quoted by a local architect?

We're very efficient at what we do. We use the latest laser measurement technology on site to measure your property. We design our plans using the latest design software on the market. We are then able to pass these savings back to you within our fees.

How good are your plans and specification?

Every day of the working week, we provide extension plans to builders and homeowners. A lot of those clients are repeat customers. We have builders who only work off our plans in every job they do, and they always recommend our services to their clients.

Examples of our plans can be found on this website.

An example of our detailed specification notes can be found here in PDF format:

SINGLE STOREY EXTENSION SPECIFICATION

 

Will I need planning permission for my single storey extension?

Since the Planning Permission Rules were relaxed on October 1st 2008, many single storey extensions now don't require Planning Permission, up to a certain size and dependant upon the type of house.

We will take care of all aspects of the planning permission on your behalf.

The Planning Portal is a good resource for finding out if your proposal needs planning permission. We will also be able to confirm the permissions needed on site, once we have a basic design done for the extension.

We would advise that if you are unsure if you need planning permission approval you put in an application for a Lawful Development Certificate (L.D.C.)
This certificate will legalise your extension and will prevent any future problems in proving that your extension is exempt from planning permission. This can save future problems when attempting to sell the property.

Will I require building regulations approval for my single storey extension?

All single storey extensions will require a building regulations approval. We will design your extension and fill out all forms regarding the building regulations application.

Will I need a Party Wall Agreement with my neighbours?

Maybe, If your extension meets certain criteria by building on or close to the party wall boundary or near to neighbours buildings then you may need a Party Wall Agreement. We will advise you on site about this issue.

Please see this explanatory booklet on the subject:

Party Wall Agreement Booklet (600kb Download)

Do You fill out the local authority application forms and submit the application to the local authority?

We fill out all forms and also act as your agent. Any questions by the local authority are directed to us. We look after the applications until the council decisions are made.

Do you charge for amendments to the plans if the local authority want our extension amending?

No, we do not charge for this. Any changes by the local authority are out of your control and we will amend your plans free of charge.

Please contact us to find out more about our services and how we might help with your project.

How many sets of plans will I receive?

We provide 4 sets of paper plans and a digital PDF copy should you wish to print your own plans. If you need any extra copies then please let us know. Extra copies of the plans can be provided at a cost of £5 per set.

More Single Storey Extension Plans:

"The plans are clear the builder knew exactly what he was quoting for. The process of designing the extension was really easy. We had to wait a while for the council approvals, but we had time to organise a suitable builder. The whole process was straightforward with great advice".

"We looked around locally for an Architect and found they didn't want to call out to look at small single storey rear extension. The architects fees we were quoted were very expensive"

"Both myself and my wife are really pleased with the extension, it saved us having to move. We felt like we were in the hands of professionals from day one and that didn't change. Our builder is now passing your number around, as he was as impressed with the plans as we have been with your service"
