Granny Annexe

Explore our range of Granny Annexe Log Cabins, offering a compassionate and practical solution for providing comfortable, independent living for elderly parents or family members right within your property grounds. These high-specification residential log cabins are designed to provide a complete, self-contained living space, offering the perfect blend of privacy for the occupant and peace of mind for the wider family. Our annexes are built with supreme quality, featuring robust 70mm thick walls from slow-grown Nordic Spruce as standard, ensuring industry-leading insulation and exceptional durability against the UK climate.

Unlike temporary structures, our log cabin annexes are built for longevity and residential comfort, featuring comprehensive specifications that include high-quality double glazing and robust construction methods. They offer versatile living spaces that can be internally partitioned to create separate sleeping areas (bedrooms), living rooms, and utility spaces ready for plumbing and electrics. Investing in a Granny Annexe avoids the complexities and expense of permanent home extensions, offering a relatively fast and attractive way to expand your accommodation. While the installation of a residential log cabin typically requires planning permission, our expertise ensures you receive a high-quality structure ready to meet the necessary building standards for habitation. Provide your loved ones with a safe, secure, and beautiful space where they can maintain independence while staying close to the family.

About Our Granny Annexe

  • Supreme Insulation with Heavy-Duty 70mm Walls

    Our Granny Annexe Log Cabins are built for year-round residency, providing supreme insulation through heavy-duty 70mm thick walls. This is a critical structural and comfort feature, as this exceptional thickness of Nordic Spruce timber ensures the cabin maintains a warm, stable interior temperature throughout the coldest months. This superior insulation, combined with high-quality double glazing, guarantees all-season comfort and energy efficiency for the occupant, making it genuinely suitable for long-term living.

  • Designed for Independent, Self-Contained Living

    These residential log cabins are meticulously designed to facilitate independent, self-contained living. With spacious footprints, the interior layout can be planned to include separate bedroom and living areas, and internal walls are often included or easily added. This versatile living space can be fitted with essential utilities (plumbing for a kitchenette and bathroom), providing a fully functional small home where family members can maintain their privacy and independence in a comfortable setting.

  • High-Specification Finish and Structural Durability

    The construction quality of our Log Cabin Annexes is unmatched. We use high-specification components designed for longevity, including robust 19mm thick tongue & groove floor and roof boards. The doors and large windows feature premium double glazing and durable frames for security. Furthermore, treated foundation joists protect the base against damp and rot, enhancing the durability and structural integrity of the entire building for decades of reliable use.

  • Practical Accommodation Solution Requiring Planning Compliance

    Investing in a Granny Annexe is a practical and attractive accommodation solution, offering a quick way to gain valuable space. Due to their residential nature, these structures typically require planning permission and must adhere to certain building standards. We provide you with a high-quality structure that is ready to meet these demands, offering a secure and stylish timber building that simplifies the process of creating long-term family accommodation.

Bespoke Enquiry

Do Granny Annexe Log Cabins require planning permission?

Yes, any structure intended for residential or sleeping accommodation (like a Granny Annexe) almost always requires planning permission from the local authority, regardless of its size. We advise seeking professional guidance before finalising your purchase.

Are these cabins warm enough for year-round habitation?

Absolutely. Featuring 70mm Thick Wall Logs or thicker and standard double glazing, our cabins offer supreme insulation. With additional roof and floor insulation, they are highly suitable for comfortable, all-season living and will effectively retain heat.

What type of base is needed for a residential log cabin annexe?

A solid, professional concrete foundation is required for all residential log cabins. This ensures the necessary stability, prevents movement, and is critical for the proper functioning of plumbing and services for long-term accommodation.

Can a bathroom and kitchen be installed inside the annexe?

Yes, the large internal area and robust structure allow the log cabin annexes to be partitioned and fitted with full kitchenettes and bathrooms. You must ensure that qualified tradespeople handle the plumbing and electrical work to meet UK building regulations.

What is the typical lifespan of a high-specification log cabin annexe?

Built with high-quality Nordic Spruce and featuring treated foundation joists and 70mm or thicker walls, our Granny Annexe Log Cabins are designed for genuine longevity, offering reliable living accommodation for decades with appropriate routine maintenance.
