Why Choose SIP Panels for Your Bespoke Granny Annexe?
Exceptional Insulation & Energy Efficiency
SIP panels deliver outstanding thermal performance, keeping your granny annexe warm in winter and cool in summer. Their superior insulation properties lead to reduced energy consumption, which translates into lower utility bills and a smaller carbon footprint. Opting for SIP technology is an eco-friendly investment that maximizes energy efficiency in your living space.
Durability & Strength
SIP panels are built for durability and strength, providing exceptional structural integrity. This robust construction ensures your annexe remains safe, secure, and long-lasting, offering peace of mind and excellent value for money.
Faster Construction Time
Thanks to the modular design of SIP panels, the construction process is much quicker than traditional building methods. With rapid assembly, your granny annexe is ready in less time, reducing disruption to your daily routine and providing quicker access to your new space.
The Building Process: From Concept to Completion
Initial Consultation and Design
We begin by discussing your vision and needs in an initial consultation. Our experienced designers will craft a bespoke design tailored to your specifications, ensuring your granny annexe fits your lifestyle perfectly.
Planning and Approvals
We handle all planning permissions and regulatory approvals, ensuring the project complies with local building codes. This ensures a seamless process and avoids legal issues.
Site Preparation and Foundations
Once approvals are in place, we prepare the site and lay stable foundations, whether through screw piles or traditional methods, ensuring a solid base for your new annexe.
SIP Panel Construction
With foundations in place, we quickly assemble the SIP panels, known for their precision-engineered fit. This rapid construction method creates the structural framework efficiently, bringing your project to life faster.
Exterior and Interior Finishing
We finish the external appearance with options like K-render or red cedar cladding. Inside, we install all necessary features, from insulation and plumbing to electrical systems, as well as custom fixtures such as kitchens and bathrooms.
Final Touches and Handover
After painting, decorating, and a thorough clean-up, we complete any final tweaks to ensure everything is perfect. Once finished, your move-in-ready granny annexe is handed over, and you can enjoy your new space immediately.
