Take the worry out of appointing an architectural designer for your extension plans
It can be a little daunting knowing who to entrust your house extension project
Afterall, there are so many design practices springing up, and with prices varying wildly.
My name is Kev Miller and I am the founder of Fixed Price Architecture Limited which is both an online and a traditional ‘bricks and mortar’ business.
I personally have over 25 years experience in UK residential design so I know a thing or two about extensions and loft conversions having succesfully designed and overseen thousands of them.
I hand picked my team of architectural designers ensuring that each one of them has brought their own individual spark to our fun and friendly architectural design practice.
Extension plans delivered within

We are certainly not your typical architectural design studio, knocking out extension plans willy nilly and charging rates that Nasa Astranaughts would be worthy of.
Our company ethic is to provide our clients with a fun, friendly and easy way for clients to get extension plans online.
We will take on board all of your ideas and aspirations and work with you to ensure your extension plans are every bit a good as you hoped they would be.
You will be assigned an architectural designer at the start of your project and they will go through the whole jouney with you from start to finish, allowing you to build up a real relationship along the way and many of our clients have gone on to become good friends.
You can message your designer at any time directly through your online project board or by downloading the app.
You can also schedule a telephone or video calls to discuss the progress of your extension plans at a convenient time to suit you.
Avoid the common mistake of paying through the roof for your extension plans
Did you know that the average architect fee in the UK is around 10% of the buid cost of your extension (this can be as much as 15% in Greater London).
With the average price of a single storey rear extension now around £28K post thats between £2,800.00 – £4,200.00 just for your extension plans!
One of the reasons for this is that many architects work on large commercial projects and a small domestic project such as a kitchen extension or a garage conversion is considered a sub-par project.
At Fixed Price Architecture we only work on domestic residential projects, it is what we do week in and week out and we are experts at it.
Typically, our fees for a set of planning and building regulations plans for a single storey extension are just £695.00
That’s a saving of £2,105.00 for most UK homeowners and a staggering £3,505.00 for those of you living in London !
*Note from our business owner, we need to put our prices up as we are doing everything those companies do – and some !
A complete one stop service for all of your extension plans needs
Some extension plans providers, both online and locally sourced will only provide extension plans that cover the planning stage, preferring not to get involved with the building regulations side of things.
There are two reasons for this, the first is laziness and the second is a lack of understanding of the built environment in general.
We have an unrivalled knowledge of UK Building Regulations and are more than happy to provide building regulations drawings for your project.
This service is extending to steel beam calculations, build-over agreements and SAPS energy certificates.
In short, we offer a simple one stop service for all of your project design needs with no need to outsource other design professionals or engineers.
Online only, or meet your designer in the comfort of your home
We can offer you two types of design service.
The first is a fully online only service whereby we would require you to provide us with some basic floor plans (or old estate agent, or previous architect plans can also be used) together with photos of your home and of course details of what you are looking to achieve with your new extension
The second service is our at your home service. If you select this service then your designer will come and visit you at your home.
You will have the opportunity to run through your project with your extension designer and they will be on hand to answer any questions you may have.
Our at home service also includes for a laser HomeScan survey of your home.
This is an increibly accurate way of measuring your home and enables us to create a 3D BIM model of your home which means your extension drawings will be incredibly accurate.

Extension Plans by Fixed Price Architecture
Our Extension Plans Directory
A set of extension plans produced by a qualified architectural designer cost £395.00 for planning drawings or £645.00 for combined planning and building regulations drawings.
Once your extension plans have been approved by planning then you have 3 years from the date of your decision notice to start work on site.
After the 3 years have passed you will need to submit a new planning application.
You can extend at the back of your house upto 3m under permitted development if you live in a terraced or semi detached property, or 4 metres if your home is detached.
This doubles to 6 metres for terraced or semi detached houses and 8 metres for detached homes under the prior approval scheme howevever you will need approval of your extension from your neighbours if you wish to go down this route.
We have created a videos on extending your home without planning permission and these can be found further down this page.
Anyone who knows how to produce accurate scaled drawings could potentially be able to provide extension plans/drawings.
We think a better question is who should draw extension plans.
And to this question we would suggest that you only use an architect or architectural designer who has a high level of understanding of the construction enviroment as well as statutory guidelines such as planning and building regulations.
If in doubt always use a professional acchitectural design firm such as ourselves.
While there are situations that certainly would call for the appointment of an architect, a domestic extension or loft conversion would not be considered one of them.
Any person who has trained and qualified as an architectural technologist and has worked in the construction industry for a reasonable amount of time would be able to produce drawings of a domestic extension to a very high level indeed.
Furthermore, for firms such as ourselves that only work on domestic extensions and loft extensions as opposed to larger commercial projects we would argue that our designers have far more experience of this type of project than many architects.
House Extensions Without Planning Permission
Here are two videos detailing extensions you can carry out to your home without planning permission.
