Exceptional frames
for inspirational homes
An oak frame annexe provides the balance so many homeowners seek – an independent living space that feels connected to the main home but doesn’t compromise on privacy.
Annexes
Whether intended for an older relative,
an adult child or the occasional guest,
an oak frame annexe adds much-prized
flexibility in an elegant way.
At Green Oak Carpentry, every oak framed annexe is designed in-house before being handcrafted by our team in our Hampshire workshop. With over 30 years of experience and a record of three Gold Wood Awards, we bring the same depth of craft and care to every project, working with you from initial ideas through final assembly to create a robust, beautiful, and individual living space.
What is an oak frame annexe?
What is an oak frame annexe?
An annexe is a smaller building next to or near a house and is designed to provide extra space. They are sometimes referred to as ‘Granny annexes’ – due to the way they’re used for elderly parents. Annexes are occasionally attached to the main house but are treated as separate buildings, typically with their own entrance doors.
Oak framed annexes have a charm of their own – the robust oak frame creates a pleasing sense of place, with a welcoming interior, thanks to the warm tones of the exposed oak beams.
How can you use an oak framed annexe?
Oak framed annexes are a
practical and appealing way
to add extra space to a home
without affecting your main house.
They’re suitable for a wide range of architectural styles and can be used for a range of purposes:
A space for intergenerational living that respects everyone’s needs – whether for elderly parents or adult children
Idyllic guest accommodation with everything your friends and family need to feel welcome
A B&B or holiday rental that generates an extra income stream
Well-appointed, private accommodation for an au pair, nanny or housekeeper
An office, studio or workshop in which to work or create, away from the distraction of your family home
However you choose to use your oak framed annexe, you’ll have a truly individual building that will add space, flexibility and value to your home.
Never repeated. Always remarkable
Every Green Oak Carpentry annexe is
an original – we don’t work to set
design templates, nor do we build the
same thing twice.
We’ll work with you to create an oak-framed annexe that complements your home and grounds, considering the architectural style of your main building and how your new oak framed annexe will interact with it. Our designers will ensure your annexe works with your garden’s layout and other outbuildings, providing a careful balance between privacy and connection.
Our fully bespoke approach accommodates your site’s idiosyncrasies – taking advantage of opportunities while managing any constraints. And, as you’d expect, we’ll work in line with local planning considerations and respect your budget.
Quality & craftsmanship
without compromise
Enjoy an unsurpassed level of continuity throughout the design, build and installation of your oak frame annexe. We guide you through your entire project, allowing you to enjoy the unique process of commissioning an oak frame building.
Design & architectural development
Our in-house draughtsmen and frame designers bring your vision to life, combining structural integrity with architectural beauty. Our designers readily accommodate unconventional ideas and specific features, and can incorporate any number of custom-designed features.
If you’ve already commissioned an architect, we’ll work with them and can adapt existing drawings to ensure your plans are suitable for oak framing.
Planning support
Our trusted planning consultants are here to support your planning permission application and are particularly experienced in heritage projects and sensitive sites.
Our materials
Oak is a popular choice for annexes, but it isn’t always the best choice for a project. We work with you to choose the right materials, based on your site, aesthetic goals and engineering requirements. We only use sustainably sourced materials.
Fabrication
Each oak frame annexe is handcrafted from start to finish by our same team of award-winning carpenters. Using skills practised since the Middle Ages, they scribe the naturally shaped components together, making each frame unique.
Build & installation
After dry-fitting your oak frame in our workshop, our carpenters deconstruct it, deliver it on-site, and personally assemble it. Using the same team throughout build and assembly creates a rare level of consistency, giving your frame unsurpassed care and respect.
Bespoke finishes & specifications
We’ll work with you to agree on the best finishing options and specifications for your finished oak frame annexe. This will allow you to appreciate the beauty of this celebrated natural material while complementing your aesthetic.
The Green Oak Carpentry guarantee
All our frames carry a warranty against defective workmanship and materials for six years. Problems are very rare, but if they do occur, we take them very seriously and do our utmost to ensure all is well.

Frequently Asked Questions
Planning your annexe
How long will it take to build an oak frame annexe?
Because each project is unique, every design and fabrication schedule is slightly different. Generally, you should allow between 4-6 weeks for your oak framed annexe design, including detailed design drawings and engineer sign-off. Timber procurement, fabrication and assembly could then take a further 8+ weeks, depending on the size of the project. Learn more about how we work.
Do I need to pay council tax on an oak framed annexe?
If your oak frame annexe is used as a self-contained dwelling, then it’s likely that you will need to pay council tax. However, depending on where you live, you may be eligible for discounts or exemptions, for instance, if a family member lives in the annexe.
Do I need planning permission for a wooden annexe?
Whether you need planning permission for an oak frame annexe depends on where your house is and whether you’ve previously extended your home. We can support you with this – our trusted planning consultants can help you decide the best way forward.
