Your journeySix steps

You'll always know what's next

01

Your site survey

If you do not already have drawings, an appointed surveyor visits for a full measured survey of your property and notes your requirements. Where it is permitted and the conditions are met, we can instead guide you through measuring up yourself and save you up to £450, see measured surveys.

Or send existing plans
02

Drawings initiated

Your project is allocated to one of our architectural designers, who designs it from the ground up around your needs.

Fixed package agreed
03

You review it

You have your first draft within 10 working days unless agreed otherwise. Send any changes and we refine until it's right.

Unlimited revisions
04

Submission & decision

We submit strategically for swift approval. Expect a council decision in around 6 to 8 weeks, and we handle any required changes for free.

100% refund if any application is refused

Technical design

Once approved, our engineers manage the technical design and Building Regulations compliance, and can provide construction quotes.
