All of our annexes and lodges are built to comply with full building regulations as standard, giving you complete confidence in the quality and safety of your new home. In addition, we provide structural calculations for added peace of mind throughout the process.

As a fully bespoke company, we offer more design flexibility than many other providers, allowing you to create a garden annexe that perfectly suits your lifestyle, needs, and budget. From your initial consultation to the final installation, our experienced team will guide you every step of the way. We also include a free site survey to help ensure a smooth and stress-free experience.

With care costs continuing to rise, a granny annexe can offer a practical and cost-effective solution for older family members who wish to maintain their independence while staying close to loved ones. Equally, annexes can provide valuable additional accommodation for younger family members, guests, or those working from home.

Every garden annexe is designed and built to your exact requirements. As a result, you’ll benefit from a stylish, energy-efficient, and comfortable living space that feels like home from day one.

Quality Granny Annexes That Add Value to Your Home

Warm, solid and made for everyday living

Our granny annexes and garden annexe lodges are fully insulated, soundproofed, and built to provide year-round comfort. Each annexe is made to order using high-quality materials and modern construction methods, creating a durable, energy-efficient home that is designed to last.

Home Extension Versus Garden Annexe

When creating additional living space for a loved one, both home extensions and garden annexes have their advantages. However, a garden annexe often provides a more flexible and independent solution.

Unlike a traditional extension, which adds living space directly onto your home, a garden annexe creates a separate, self-contained unit within your garden. This allows family members to maintain their privacy and independence while remaining close by for support when needed.

In addition, garden annexes can often be installed more quickly and cost-effectively than conventional extensions. Planning requirements may also be simpler in some cases, helping to reduce delays and streamline the overall process. As a result, you can benefit from additional living space sooner, with less disruption to your daily life and greater peace of mind.
