Oak annexes are a great way add extra living space that blend with your home. At Hardwoods Group, we specialise in bespoke oak frame kits, crafted to your exact requirements and built from premium-quality, sustainably sourced oak.

Precision-Crafted in the UK

Each oak annex frame is manufactured in our UK workshop, blending traditional joinery methods with modern CNC precision. From upright posts to glazing systems, every component is engineered for strength, longevity, and aesthetic appeal.

Designed for Self-Build Simplicity

Your oak annex arrives in a kit ready for installation by your builder or contractor. We supply comprehensive instructions and support to help ensure a seamless build process.

With their timeless design and natural character, our oak annexes create inviting living spaces — whether used as a guest room, home office, granny annexe, studio or garden retreat. We offer a fully bespoke design service, tailored to your property, layout, and requirements.

You can either submit your own measurements and drawings, or work directly with our design team and have them produce detailed 3D CAD drawings for your approval before manufacturing begins.

No two homes are alike – and your annexe should be just as unique. That’s why we offer a fully bespoke design service, tailored to your property, layout, and requirements.

Our experienced design team uses advanced 3D CAD software to create detailed drawings that ensure every component of your oak frame fits perfectly. This precision allows for a smooth supply and installation process – ideal for both trade professionals and self-builders.

You can submit your own measurements and drawings, or work directly with our designers to bring your vision to life.
