The pre manufactured sips kit offers a more straightforward solution to creating additional space than the traditional method of a home extension. Garden rooms can even add around 5% more to your home’s price tag, as well as adding multi-functional space in your home. These remain popular for any competent DIY'er or investor wanting to ‘flip’ a property with lower budgets.

    What is included in the DIY Garden room kits?

    Our standard shell kit comes with everything you need to build a sturdy and weatherproof building. The shell kit includes high-quality SIP panels for the floor, walls, and roof, providing an insulated structure with excellent strength. Structural timbers are also provided to ensure a solid framework. For the base, we supply Visqueen to be placed between the concrete base and the SIP panels for added protection against moisture. A roll of waterproof, breathable membrane is included to cover the walls, keeping them dry and well-ventilated. All necessary fixings are provided, making our kits straightforward to assemble.

    Optional extras are also available for those wanting to take your garden room to the next level. We offer the option to add a facia pack or rubber roof kit, or even add an additional window or door—the possibilities are endless. 

    HOW LONG DO GARDEN ROOM KITS LAST?

    Modern garden room kits are constructed to be durable, with many lasting well over 20 years. By choosing high-quality windows and external cladding for your garden room's finish and performing light maintenance, you can ensure your garden room retains its longevity and remains a valuable addition to your outdoor area for decades to come.
