High-Performance Granny Annexes and Garden Rooms in Kent

Demand for granny annexes in Kent continues to rise as homeowners seek practical multigenerational living solutions. Our modular garden annexes in Kent are designed within Caravan Act limits, allowing compliant installation in many residential gardens without the need for complex planning procedures. Each annexe is fully self-contained, incorporating insulated wall and roof assemblies, energy-efficient glazing and durable internal finishes suitable for permanent occupation.

For properties in both rural and suburban areas of Kent, our insulated garden rooms offer a residential-standard alternative to lightweight outbuildings. Using Cross-Laminated Timber panels and precision manufacturing, we deliver modular garden rooms that provide improved thermal performance, reduced thermal bridging and enhanced structural stability. This ensures comfortable year-round use as home offices, guest accommodation, rental annexes or independent living spaces.

Off-site fabrication ensures consistent quality and faster on-site installation. Every modular garden annexe supplied in Kent is built under controlled factory conditions before efficient delivery and assembly, minimising disruption to the main dwelling. From compact one-bedroom granny annexes to expanded two-bedroom garden lodges, our CLT modular systems are engineered for long-term performance and energy efficiency.
