SIP Extensions by Cabiny
A smarter way to extend your home.
If you’re looking to expand your living space with minimal disruption, faster build times, and improved energy efficiency, a SIP extension could be the perfect solution.
Why choose a SIP extension?
SIP stands for Structural Insulated Panels. Unlike traditional brick-and-block builds, SIPs are pre-engineered panels that combine structure and insulation in one. They form the walls, floors, and roof of your extension and are manufactured off-site, then assembled quickly once delivered.

SIP Extension Benefits
Design flexibility
Whether you're after a home office, open-plan kitchen, or garden room, SIPs can be tailored to suit your vision – with clean lines and modern finishes.
Cost-effective
Shorter build times and reduced energy usage mean SIPs can work out more affordable than traditional extensions in the long run.
Cleaner, quieter installation
With pre-fabrication done off-site, your garden doesn’t become a building site for weeks. Plus, less heavy machinery and noise.
Faster build times
SIP extensions go up in a matter of days, not weeks. With less time spent on site, you’ll experience minimal disruption to daily life.
Outstanding insulation
The airtight, highly insulated panels keep your home warm in winter and cool in summer – helping to lower your energy bills.
Sustainable choice
SIPs use less timber than traditional framing, create less waste, and are incredibly energy efficient. A great option for eco-conscious homeowners.
