Structural Insulated Panels (SIPs) offer a modern, efficient alternative to traditional timber construction and are ideal for building high-performance garden rooms.
Examples of SIP Garden Rooms




SIP panels are made from two outer boards of OSB3 (Oriented Strand Board) with a rigid layer of insulation sandwiched between—hence their nickname: sandwich panels. This simple yet powerful construction method delivers a host of advantages. Here are some of the SIP panel benefits:
Rapid Installation
SIP panels are lightweight and easy to handle—two people can lift and position them with ease. Their design speeds up the entire building process, allowing your garden room to be erected in days, not weeks. Our custom SIP kits arrive pre-cut and ready to assemble, complete with jointing splines, supporting timbers, and full instructions.
Made to Measure
Every SIP kit we produce is bespoke. We manufacture to your exact specifications, giving you complete freedom over the size and layout of your garden room. Once built, you can finish it with your own choice of cladding, doors, windows, and internal features (note: we do not supply these elements).
Energy Efficient
The high-performance insulation core of our SIP panels helps create an airtight building envelope that retains heat and reduces energy loss. This results in lower heating bills and a more eco-conscious construction method compared to traditional builds.
Sound-Reducing Properties
In addition to thermal insulation, SIPs also offer excellent acoustic performance. Their dense insulation helps reduce external noise, making them perfect for studios, garden cinemas, or music rooms.
Year-Round Comfort
SIPs create a fully insulated, weather-resistant structure that keeps you cool in summer and warm in winter. Their superior thermal regulation means your garden studio remains comfortable 365 days a year—whatever the weather.
Environmentally Friendly
SIPs are more sustainable than conventional timber construction. They require fewer raw materials, generate less waste, and their energy efficiency contributes to a reduced carbon footprint over the building’s lifetime.
Lower Build Costs
With less time on site, reduced labour requirements, and minimal waste, SIP construction can significantly lower overall project costs. They’re not just quicker—they’re more affordable too.
