Oak frame extensions are the ultimate home upgrade – adding character, style and valuable, additional space to your property.
Oak frame extensions can be designed to fit all kinds of schemes – suiting both contemporary and traditional-style homes. The material is a premium structural option, and is usually cut and prefabricated offsite – allowing speedy build times and impressive results.
As with any extension, whether or not you’ll require planning permission will depend on the size, location and design details – ie the cladding and exterior finishes. You can do plenty under permitted development but it’s always worth checking with your local planning authority. Many oak frame suppliers will advise you through planning as part of the process, while also offering a Building Regulations package.
The majority of oak frame extension designs feature plenty of expansive glazing, and some with full-height glazed gables or vaulted ceilings. This is popular as it allows the oak to really shine while ensuring a light-filled, wow-factor extension. But how can you design an oak frame addition that’s perfect for you? Take a look at our collection of inspiring ideas.
Set on the banks of the River Dart in Devon, this cottage has been extended to form a large, open-plan kitchen/dining/living room with panoramic views. Due to the site’s gradient, the floorplan is partly elevated with the outlook through the glazed gable end seeming to project out over the water.
The arch brace frame by Carpenter Oak has hidden steelwork to reinforce the structure and bifold doors open onto a side terrace.
The build system you choose for your extension project may influence how it looks and feels. Building with oak creates the perfect opportunity to leave the skeleton exposed, meaning you can transform your extension’s structure into an amazing design feature. Oakwrights masterminded this two-storey addition, which holds a kitchen-dining-living area and master bedroom suite.
The previous single-storey link and double-storey extension in this house had a disconnected layout, making rear rooms redundant. The homeowners achieved planning to rebuild on the same footprint.

Typical for houses of the era, this beautiful 1920s Arts & Crafts home was a little dark inside.

This contemporary barn extension, designed by Carpenter Oak, provides a new kitchen and link between the historical and sensitive stone barn buildings. The design adopts a contemporary look and feel, using the oak to create an open-plan, vaulted roof form.
The owners wanted the new space to feel well-connected to the garden beyond. They chose big glass screens that slide open between the oak posts – ensuring the kitchen and dining areas have much greater connection with the outside areas and far-reaching views over Dartmouth.
For this project, the homeowners wanted a glazed sunroom, accessible from their kitchen and study, to use as a relaxing living room. The addition was positioned to capture views of their garden and river beyond.

Contractors C Curtis Building completed the design work in-house using a 3D model. The pre-mortised and tenoned frame was fabricated by a German supplier, and erected with oak dowels in one-and-a-half days.
EXPERT VIEW Designing the perfect oak frame extension
Luke Copely-Wilkins from Carpenter Oak shares his insight on designing the right oak frame extension for your home
What can you achieve in the design of an oak frame extension that you can’t with bricks and mortar? A bespoke oak frame is not only structural but also visible, so the oak brings texture and warmth to a home that improves with age. Vaulted ceilings and exposed beams add character.
Thinking ahead will help you plan a space that’s not only aesthetically stunning but functional, too. Who will use the extension? How will it be used and how do you want to feel when you’re in it? Which part of the house will the addition connect to? What would you like to see when you look out of the windows? For example, opting for large-scale integrated glazing will bring lots of natural light into your new space.
Both! There are limitless design opportunities with oak systems. We’ve planned and built everything from traditional frames to stunning contemporary structures integrating steel. Almost anything you can imagine is possible.
Oak frame extensions are built with modern methods of construction and insulating external panels to ensure airtightness and a stable internal temperature. Be sure to use an expert designer so that every aspect is fully considered.
Whatever your chosen extension style, it’s the oak that brings the wow, whether via a dramatic vaulted ceiling, exposed beams or a post you can run your hand over to appreciate its character and warmth up close. A unique, handcrafted frame with beautifully integrated glazing always looks exceptional.
The owners of this Cheshire farmhouse decided to extend the living area at the front of their home with a 30m² oak frame garden room. After being inspired by the character of local buildings, they went to see Oakwrights. They were attracted to the company’s method of crafting the oak in a workshop and the face glazing system that allows the use of glass to be maximised without compromising energy efficiency.
Symmetrical windows and oak trusses were an important aspect of the design, as were the traditional double doors that open onto the patio. An inset woodburner and underfloor heating keep the room warm in winter.
An impressive orangery by Prime Oak has added space and rejuvenated the layout of this Hertfordshire home by providing the missing link to connect the kitchen, living room and garden. An abundance of natural light floods into the dining area before spreading throughout the downstairs, thanks to a roof lantern and wide glazed doors on two sides.
The flat roof surrounding the lantern is insulated and finished in a subtle grey rolled lead to draw the eye to the wood tones in the oak frame.
This stone home in the Cotswolds benefits from an unusual garden room design, with six angled windows that take in the grounds and countryside views. The new zone extends the kitchen seamlessly into a comfortable seating area, where the homeowners chose to accentuate the volume and drama of the frame with exposed trusses. The frame was supplied by Welsh Oak Frame.
The direct glazing system made it possible to create the building’s curved shape with floor-to-ceiling glass, while the solid wall allowed an inset fireplace to be installed for cooler months.
