🌿 What’s in Your SIPs Kit – Unique Garden Retreats
Build for the future. Build sustainably.
At Unique Garden Retreats, we don’t just create beautiful buildings — we supply the same high-performance SIPs kits that make our garden rooms, garages and extensions stand out for their strength, energy efficiency and speed of build.
Whether you’re a tradesperson, self-builder, or developer, our ready-to-assemble SIPs kits are cut to precision, clearly labelled, and delivered across the UK. Each kit provides the foundation for a sustainable, warm, and long-lasting structure.
⚡ Why Choose SIPs?
SIPs (Structural Insulated Panels) are the smarter, faster way to build.
Each panel combines a rigid insulation core sandwiched between two sheets of engineered OSB, creating a structure that is strong, thermally efficient, and quick to assemble.
Key benefits include:
-
🏗️ Rapid construction — assemble a watertight shell in days, not weeks.
-
🌡️ Outstanding thermal performance — achieve low U-values and reduced heating costs.
-
🌍 Sustainable and efficient — less waste, fewer deliveries, lower energy use.
-
🔩 Superior strength — engineered to outperform traditional timber framing.
-
🏡 Versatile design — ideal for garden rooms, extensions, workshops, garages, and annexes.
