Beautifully original,
naturally liveable
Extensions
A well-designed oak framed extension does
more than add space – it becomes a natural
part of the home it joins.
With over 30 years of experience and a record three Gold Wood Awards, Green Oak Carpentry will design and handcraft your oak framed extension to your exact brief in our Hampshire workshop.
We work directly with homeowners and partner with architects and building firms. Every extension we create is individually designed, engineered and handcrafted – from oak framed orangeries and kitchen extensions to oak framed conservatories and family rooms.
What makes our oak
extensions different?
Each Green Oak Carpentry extension is a true original – individually designed, engineered and handcrafted by our team of expert, traditionally trained carpenters. We combine heritage oak framing techniques with contemporary knowledge to ensure your oak extension looks beautiful, works hard and lasts for years to come.

Begin your legacy,
build in oak
Oak has a natural warmth and beauty that few materials can match. Whether you’re commissioning a conservatory, orangery, pool house or sun room, your oak extension will bring character and utility, giving you a space that always feels inviting.
Many oak extensions feature vaulted ceilings, exposed trusses and generous glazing, connecting them to their surroundings in a way that feels carefully considered. Prefer a more contemporary appearance? We’ll work with you to design, build and assemble an oak extension that meets your exacting requirements.
Oak’s exceptional durability means it requires minimal maintenance; an important consideration for a building exposed to the full force of our unsettled British weather. As a natural insulator and renewable material, it is an energy-efficient and responsible choice – a building that treads lightly and lasts.
Every project is a one-off
No templates. No repeat designs. Every frame
we have ever made has started from scratch.
Never repeated.
Always remarkable
Explore our project gallery to inspire your oak frame building project. Take your time; each Green Oak Carpentry structure is unique and hand-built – you’ll never see the same project twice.
“We are delighted with our oak framed extension. The authentic design and features have created a beautiful space which perfectly complements the character of our listed thatched cottage.
