Save £3000* Versus a Traditional Architect

Whether you’re looking to build a new open-plan kitchen/diner or an extra bedroom, our online service ensures a hassle-free experience in obtaining the necessary plans and approvals. Lots of house extensions don’t require Planning Permission these days but many still do. Even if your extension plans fall under ‘Permitted Development’, it is still extremely likely that you will need some form of Architectural Drawings.

Paperwork & Planning Can Be a Headache!
Let Our Team of Experts Handle It

A Building Notice

This is just a form that states you are building an extension. It enables the inspectors to quote your fees and tells them to expect to carry out some site visits soon. However there are no extension building regulations drawings produced with this option and you or your builder can submit the Building Notice.

Full Plans Application

The one we would recommend. So, Architectural Building Regulations Drawings are produced by us and are pre-checked by the Building Control Officer before building work starts. This means you can be entirely confident that you will not be building anything non-compliant and have to make costly corrections.

Permitted Development

Check the UK Government guide HERE to see if your extension requires Planning Permission. Even if it’s considered Permitted Development, we still recommend applying for a Lawful Development Certificate. This not only ensures compliance but is also valuable when selling your home.

Are your Architectural Designers based in the UK?

Yes, all of our Architectural Designers are based in the UK.

How can you guarantee I will get planning permission and building control approval on the Premium plan?

We currently achieve a 94% success rate with planning dept applications and 100% success rate with building control. We are so sure that you will have the best chance of success with us that if the planning dept or building control inspectors refuse your application, we will either:

a) Fully refund all monies paid to us - no questions asked.
b) Or continue to work on your project making design changes and submitting additional applications until an approval is reached for FREE.

Are your Architectural Designers self employed?

No. All of our Architectural Designers are full-time employees of Arkiplan Architectural Limited. We do not "outsource" your project to freelancers or temporary/contracted staff.

Have you worked with my council / Local Authority before?

Yes. We have submitted Planning Applications to every council in the UK, some of them many, many times.

Are you able to provide Structural Engineers calculations on my project?

Yes. Absolutely. We will send you a quote once we know the full extent of your proposed building work.

Is your 3D Home Scan survey accurate?

Yes! It is 99% accurate which is actually far better than a laser measure/tape measure and sketch pad. Not to mention, we can "re-visit" your home whenever we need to just by opening the scan file so no dimensions will ever be "assumed" or "guess-timated".

What if I need design changes?

We include three full rounds of unlimited design changes in every quote. These can be utilised at any point throughout the project, whether they are early tweaks or if the planners request changes.

On average, our customers save £3000* with us, rather than using a traditional architect, so that’s the new kitchen sorted.
