Project description

If you have any inspirational ideas or images, now is the time to discuss, send across anything you have that will help us put together your first draft plans. Havent got any ideas? Don’t worry, simply give us a “wish list” of what you would like, and we can work our magic to come up with some ideas and make best use of the space.


Now its out turn to get to work. Our Standard Drawing time is 12 days; however, we can offer fast track packages, within 6 days (+ £97.00), within 3 days (+ £347.00) or next day turn around (+ £497.00).

Receive your drawings

We will email you a copy of your plans ready for review, we will then work with you on the design until you are happy with the design and happy for the plans to be submitted to the council. Included in our fee we will also submit one application to the council on your behalf (Council fee excluded).

Why Are We Competitive For Planning Costs?

Despite what you may of heard, cheap doesn’t always mean poor quality. Imagine a company that provides a good service and quality drawings without ripping its clients off… The average architect fee is around 10-15% of the build cost, that’s £4,000 – £12,000 in drawings! Don’t get us wrong, we believe there is a time and a place to charge this fee, but not for a simple extension, loft conversion or garage conversion.

Do we cut any corners because we are considerably cheaper? No, of course not, drawings have to be a certain standard to be accepted by the council and building control officer, you can’t cheat the system, and we certainly wouldn’t be where we are by cutting corners. Save yourself some money and let us help you through your project.

Did we mention we are ARB registered?

Frequently Asked Questions About Extension Planning

How is it such a quick turnaround?

When appointing an architect, a lot of time is lost due to organising the initial meeting, the site survey and any follow up meetings. As our customers provide the necessary measurements of their property we are able to start the drawings process immediately. Any conversations our customers wish to have is addressed through a telephone conversation and we always on hand for questions and queries. By removing site visits and unnecessary meetings from our process we can focus on providing your drawings as quickly as possible.

How is the fixed price guaranteed?

The majority of architects work on an hourly rate or a percentage of the build costs which makes it impossible to offer a final price until works have been completed. This can lead to unforeseen costs and an unexpectedly high final invoice. We have streamlined our service to provide you with only that which is necessary. We charge for your drawings only and will give you the finished price before you appoint our service, this includes one revision of your first draft plans.

Can I carry out my own survey?

Yes! All you need is a tape measure. Add the necessary measurements of your property onto a quick sketch and we will do the rest. If you have estate agents floor plans you can add the measurements to these plans to make the process even easier. If you neighbour has a similar layout and has previous architectural plans then we could also work from these. Please see our guide for more detail.
