Process & Timescales

An efficient seven-step process, designed to make your annexe experience stress-free and enjoyable.
01. Phone Consultation

Our free, in-depth telephone consultation is your first step towards a beautiful new annexe. One of our friendly experts will guide you through everything you will want to know, including planning permission options and potential costs.

02. Quote & Drawings

After our consultation, you can expect to receive a detailed quote and annexe drawings within a couple of days. For you to make an informed decision, we include a fully itemised quotation and drawings (footprint and elevations).

03. Site Survey

Your project manager will make an onsite visit to survey your garden and ensure everything is 100% accurate. We’ll check utilities, such as drainage and electricity, plus we review any details that may affect your planning application(s).

04. Build Specification

Our annexes come fully fitted with everything you need to move in right away. But an exciting part of our process is choosing your desired internal finishes, and we have a great range of colours and styles for you to choose from.

05. Planning Permission

A key part of our turnkey service is obtaining permissions from your Local Planning Authority (LPA) to build your annexe. We work with an independent planning professional to get you the best results.

06. Project Build

With planning in place, we'll start on the groundworks in your garden, whilst we manufacture your annexe at our site. Overall, the full process typically takes 6 to 9 weeks, depending on the size of your chosen annexe.

07. Completion/Handover

Once our team has added the finishing touches to your annexe and connected the home to utilities, your loved one can move in right away. And your annexe will be covered by a 10-year insurance backed guarantee.
