Premium-quality garden rooms
Siptekk delivers premium-quality home extensions that far outperform conservatory-style structures and other lightweight, non-traditional alternatives. Our extensions are engineered to provide genuine long-term value, enhancing both your living space and your property’s overall market appeal.
Each building is constructed using our advanced structurally insulated panel system, ensuring superior strength, energy efficiency, and year-round comfort. To suit a wide range of architectural styles, we offer an extensive choice of exterior finishes, including durable silicone colour-fast renders, natural Canadian cedar or larch cladding, and robust composite cladding options. Where a more traditional aesthetic is desired, Siptekk can also incorporate a secondary outer wall to allow for brickwork or natural stone finishes.
Our precision-engineered system ensures rapid installation while delivering a modern, high-performance extension with exceptional attention to detail. Every project is designed to seamlessly blend with your home, creating a functional and visually cohesive addition tailored to your needs. With Siptekk, you receive a long-lasting, low-maintenance extension that elevates comfort, efficiency, and property value.
