We’ve streamlined the architectural process
You’re busy and you live in Britain – the last thing you want is endless days off work having meandering in-person conversations over pencil-drawn floor plans.
We visit once, quickly, to create a true-to-life digital scan of your property. After that, everything is handled online and on the phone with a minimum of fuss, so you can extend easy.
We have a 90% planning approval rating
Having rescued a team of ex-local authority officers from across the country, our planning team know the planning permission playbooks inside and out. This gives your project the greatest chance of getting the council’s green light, so you can enjoy your new home sooner.
And a network of vetted builders to pick from
Our Connect service helps you find the right contractors to make your designs a reality. There’s no additional cost, and we’ll sit down with you to go through your project’s tenders and find the most suitable company to fulfil your build.
