What Is a Garden Room — and Why Everyone Wants One
A garden room is a fully insulated, year-round building installed in your back garden. Unlike a shed, it has proper insulation, electrics, windows, and walls built to house-quality standards. Most clients use it as:
Garden Office
Escape the kitchen table, work in peace, no commute
Studio
For art, music, podcasting or crafts
Home Gym
Your own private fitness space, ready in days
Guest Room
Extra space for family, friends or rental income

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
factory-cut panels ensure accurate fitting and reduced material waste.
Energy & Cost Efficiency
Lower labour time and improved insulation result in long-term savings.
Ground Screw Foundation Option
A fast, practical alternative to concrete foundations — minimal excavation, no waiting for concrete to cure.
Ground screws provide a fast and practical alternative to traditional concrete foundations for many garden room projects. They can be supplied as an optional extra with your IRSIP garden room kit — ground screw supply and installation are available at additional cost.
