How does D&B work?

Quote

Tell us about your favourite model, or we’ll work with you to design your own. We’ll send you a quote and will outline any other costs that may apply to your works.

Pre-liminaries

If planning permission is required, we’ll assist you with a submission. It can take 8-12 weeks for a council’s decision. The cost is deducted from your project cost.

Deposit

Once approved, we’ll ask you to pay a deposit which secures your project. We’ll be busy behind the scenes setting up your project and arranging timescales.

Preparation

You’ll need to install services and a foundation prior to our arrival. We’ll help you to set this up by providing a specification and find tradesmen local to your site.

Build

Our team arrives to begin construction which can take around 8-12 weeks from start to finish. Any landscaping works would be finished after the build.

Handover

On completion, we’ll snag the works and any last bits are tidied up. We’ll exchange keys, issue your certificates and your insurance backed guarantee is sent to you.

  • "We were in a hurry to get our project started, we had an online call with Ryan and he sent our plans within a couple of days. It saved us quite a lot of time and money getting set up. Highly recommended."
