Steps to your brand new Tranquil Garden Room

  1. Firstly, please fill out the contact form and we will get back to you as soon as possible.

  2. We will then contact you to discuss your design requirements in more detail, for example,  the use, style and requirements you need for your garden room.

  3. Using the information you have provided, a 3D design and quote will be sent to you.

  4. When you are happy with the design, a home visit will be arranged to finalise details, such as types of cladding, flooring etc. This is where you can choose any finishes and design features you require.

  5. Once you are happy with the final design we will organise a start date that suits you. 

  6. On arrival all the materials needed for your garden room will be delivered, they will all be pre-cut and prepared so the impact on your garden and time is minimised.

  7. On average it will be around 6 weeks from when the 50% deposit is paid to the start date, and we aim to be finished within one to two weeks (depending on access to your garden).

  8. Once your garden room is completed and the remaining 50% balance has been paid you will receive the keys to your brand new Tranquil Garden Room!
