When you are happy with the design, we can create an order form & arrange installation.

Book an installation date:

We will now arrange a start date and take a deposit. We will also outline the payment structure and dates for each installation during the progress of build.


You will have direct communication with your designated Project Coordinator throughout the entire process. This means that all communication is with one allocated person.

Detailed Planning:

You are going into the finer detail. This is where you can decide on where you would like your light fittings, sockets & switches. We will also give you an electrical plan to show your wires for future safety. We will also confirm the exact location of your garden room.

Final Chance to add Extras:

We now have an installation date booked in and 99% of your build arranged; however, from experience, we find that clients make last-minute changes. We can facilitate minor changes up to 72-hours prior to the installation date. These changes include more electrical points, such as sockets, heaters & lights, additional decking and, changes to internal paint colours (these changes do not include structural changes).

Installation & Delivery:

Our team will be on-site for the delivery of all materials, and the work will begin when our main structure is delivered. This will be pre-booked with you in advance. The foundations generally take 1-Day to complete, and the main structure takes roughly 5-7days to complete. The room may not be usable at this stage, as depending on weather conditions, the plaster could take a few days to dry.

Quality Inspection

Once the main structure is up, one of our Manager’s will visit the site and conduct a detailed inspection of the garden room to ensure they are fully satisfied with the build quality. At this time, we can answer any questions you have about your new room.

Yes, we can use cedar cladding on your outbuilding. We will have to quote for the cedar at the time of your order due to constant prices changes in the timber market.

Composite cladding requires little maintenance. Unlike timber cladding, composite does not need annual treatment and can be left with no fear of rot.
