OAK FRAMED ANNEXES
An oak-framed annexe offers a practical way to provide a self-contained living space for relatives, guests, or extended family. Designed and built using traditional joinery techniques, each annexe includes everything needed for independent use – from bedrooms to kitchen areas. In many cases, these buildings fall within permitted development rights, meaning full planning permission may not be required.

Is An Oak-Framed Annexe Right For You?
An oak-framed annexe is a long-term solution for creating an independent living space without the need to extend your main home. Unlike a standard garden room, it’s a fully self-contained building, typically including one or two bedrooms, a kitchen, and a bathroom.
Whether used as a granny annexe, guest accommodation, or a home office with overnight facilities, it offers flexibility and lasting value. Every one of our timber frames is made from structural oak, built to order, and designed to meet your specific needs.

Custom-Building Your Oak-Framed Annexe
Every oak-framed annexe design begins with your requirements, whether that’s a layout for a family member, guest use, or rental. We can work from your architect’s plans or help shape the concept from scratch.
Our team welcomes your inspiration, photos, and style references to guide the look and feel. We’ll also advise on practical constraints, such as beam spans and post placement, to ensure structural integrity. We can also match features from your main property to keep everything consistent.

Planning Permission & Building Regulations
In some cases, an oak-framed annexe can be built under permitted development rights. To qualify, the structure must be single-storey, under 2.5m at the eaves (and 4m overall with a dual-pitched roof), and placed behind the main house. However, because an annexe is habitable, building regulations will usually apply – especially if it exceeds 30m² or sits close to a boundary.

What’s Included In Your Oak-Framed Annexe Kit
We supply everything needed to construct your oak-framed annexe: the structural frame, roofing, cladding, insulation, and any required joinery such as doors and windows.
Plumbing and electrical work are not included and should be arranged separately. We offer a full build service for projects within our local area, and supply-only options nationwide.
Both single- and double-bedroom layouts are possible, and each annexe is made to order based on your requirements.

That depends on your site and setup. In many cases, a single-storey oak-framed annexe can be built under permitted development rights. Granny annexes, however, tend to include bedrooms and living facilities, making them more likely to require formal permission.
We recommend speaking to your local authority early, with our team able to supply planning drawings if needed. We’re also happy to advise on how best to approach permission and compliance.

Yes – many customers build an annexe for family use but later adapt it for short-term letting or guest stays. Just be aware that different planning or tax rules may apply, depending on how the space is used.
Yes. We can either work with your architect or lead the design process ourselves. Our in-house team specialises in oak frame buildings and can provide advice, planning drawings, and practical input throughout.
We can. Whether it’s matching rooflines, cladding, or joinery details, we’ll ensure the annexe feels like a natural part of your property.
