Single Storey Extension Design

We use the latest Cad software to design your single storey extension. We offer a cost effective design solution for Planning Permission and Building Regulation applications.

Single Storey Extension Design at affordable fees.

Single Storey Extensions

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 new kitchen
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

"A good service, many thanks for the plans. Your ideas really helped us make up our mind about the extension and the extra space we required. The builder quoted us accurately from the plans and his price didn't change".

"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"

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

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

We deliberately keep our overheads low, we don't employ a secretary or have a glass fronted office in a city centre. We pass these cost savings back to you in our prices. We also use the latest C.A.D. (Computer-Aided-Design) programs to produce our high quality plans and to help save us time.

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.

Please click on the easy-to-use, interactive Planning Permission guide below, to find out more about the planning process and if your extension requires permission.

We will take care of all aspects of the Planning Permission on your behalf.

Will I require Building Regulations Approval for my single storey extension?

Yes, Building Regulations Approval will be required. We will produce the Technical Drawings for you, and submit them to your Local Authority for a full Building Regulations Approval.

Do You fill out the Local Authority Application forms and submit the application to the Local Authority?

Yes, we do all the hard work - so you don't have too. We submit your applications to your Local Authority and act as agent until the approvals arrive.

Do you charge for amendments to the plans if the Local Authority want our extension amending?

No, we do not charge for this. We don't think its fair that you should be charged extra for something you don't have any control over. 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 you with four sets of plans and supply the Local Authority with as many sets as is required for the Planning Permission and Building Regulation Applications.
