Having determined your requirements and advised a lead time we will arrange a convenient date for delivery and the start of the installation of your garden office building on the site agreed. We will instruct our sips panel manufacturer who will program in your order and produce the panels.
From this point you will have direct access to your project manager, who will keep you informed of all aspects of the production and installation process. Our team will arrive to unload and create a work site within your garden area. We are ever mindful that this is your private garden and do our utmost to keep it safe and tidy.

Installation stages of your garden room

  1. Either prior to delivery or within the install process, depending on groundwork requirements, the buildings foundation system will be installed for the garden office or garden room building.
  2. A vehicle will arrive with all of the SIPS panels and major components to start the installation.
  3. When the main structure (Floor, walls and roof) is recognisable as a garden office building the windows and doors will be installed.
  4. Now it is a case of doing all of those things that appear to take most of the time! Roof membrane, cedar cladding, electrics, plastering, painting, flooring, all detailing and any additional items that comprise your garden office.
  5. Additional works such as landscaping or decking
  6. Finally clean the office and garden site. Pass over documentation for any technical items (climate control, underfloor heating etc) electrical certification and then hand over the keys! You are now able to enjoy your garden  office for many years to come...
