Speak With Our Manager
All details — dimensions, layout, customisation options, 3D design, pricing and installation — can be discussed directly with our manager, who will guide you through every step and help you choose the best solution.
We offer a nationwide installation service through trusted crews. Choose the level of support you need — from preparing the base to full on-site assembly and finishing. One point of contact, clear timelines, and a smooth build from start to finish.
Installation Services
Our installers assemble the SIP structure on site and can take the project further with roofing, windows and doors, electrics, and internal/external finishes. You can choose SIP kit installation only, or a complete turnkey build.
Fast, professional assembly
Your SIP panels are manufactured in our own facility for consistent quality and accurate fit. Everything is cut and prepared to speed up the build on site — less waste, fewer delays, and a structure that performs.
Precision-made in our factory
Our preferred foundation option is ground screws — a fast, clean way to create a level, stable base for your garden room. We assess your site and specify the right screw layout so the platform is ready for installation quickly, even on uneven ground.
Ground Screws Foundation
The price shown is for the SIP structural kit only: pre-cut SIP panels, structural timber and fixings. Delivery, foundations, installation, windows/doors, electrics and finishing can be quoted separately as part of an installation or turnkey package.
Your kit includes wall, floor and roof SIP panels cut to the chosen design, pre-cut components, structural timber and fixings. A kit schedule is provided so you can see exactly what’s supplied.
Yes. We can arrange installation through our team/approved installers. You can choose SIP structure assembly only, or a full turnkey build including finishes.
It depends on your site conditions and access. Common options include a concrete slab or a raised base system. We’ll advise the most suitable solution after a quick review of your site details.
Many garden rooms can fall under permitted development, but it depends on size, height, location and how you intend to use the building. We recommend checking your local planning authority. We can share typical guidance based on your model.
Yes. We can often adjust dimensions, openings, and internal layout depending on the model. Send your requirements and we’ll confirm what’s possible.
Lead times vary by model and workload. Once you’ve chosen your design, we’ll confirm the current production and delivery schedule before you place an order.
Kits are packed securely to protect panels in transit. You’ll receive delivery guidance in advance, including access requirements and offloading options.
SIPs are designed for construction environments, but they shouldn’t be left exposed for extended periods. We recommend keeping panels covered and installing roofing/weather protection as early as possible.
SIP panels are insulated as part of the panel core. Any additional insulation depends on your specification and intended use (e.g., year-round use, heating type, building regs requirements).
Electrics are typically planned in advance and installed by a qualified electrician. If plumbing is required, we’ll advise the best routing based on your layout and specification.
With a proper foundation, correct installation, weatherproofing and routine maintenance, a SIP garden room is built to last for many years.

Benefits of SIPs
Structural Insulated Panels (SIPs) are at the forefront of construction methods, and a key element to the future of the industry.
Superior Thermal Performance
High insulation values reduce heat loss and improve energy efficiency year-round.
Faster Build Time
Factory-cut panels significantly reduce on-site construction time.
Structural Strength
Engineered panels provide high load-bearing capacity and structural stability.
Airtight Construction
Reduced thermal bridging improves internal comfort and lowers energy costs.
Precision Manufacturing
CNC-cut panels ensure accurate fitting and reduced material waste.
Energy & Cost Efficiency
Lower labour time and improved insulation result in long-term savings.
