Quality Granny Annexes That Add Value to Your Home

Warm, solid and made for everyday living

Our granny annexes and garden lodges are fully insulated, soundproofed and built to last. Each one is made to order using modern construction methods and quality materials, with a finish that feels just like home.

They install quicker than a standard extension, cost less and often don’t need full planning permission. That means less waiting, less stress, and more space ready to use when you need it.

Garden Annexe FAQs

We design and install bespoke granny annexes, garden lodges, offices, hobby rooms and garden rooms. All are made to order and tailored to your space and needs.

All kitchens, bathrooms and fitted furniture are part of our standard build. There are no hidden charges.
