3. Make a Wish-list for an Oak Extension
The design of your oak frame extension will hugely depend on how you will utilise the new space. Sitting down and creating a wish-list of features or an outline of what you want to achieve will go a long way in creating a great design brief so your architect or supplier can make the most of the extension.
The homeowner of this two-storey extension wanted a large master bedroom with views out across the countryside plot, while still in keeping with the cottage's period style.
4. Choose How Much Oak to Leave Exposed
When building an extension in oak, one element that will hugely impact the interiors is how much of the frame you choose to leave exposed. Generally, for a more modern look highlighting vaulted ceilings with the trusses showing but covering supporting posts is a great choice, while a more traditional style might leave the whole frame on display.
How much oak is left exposed will also have an impact on finances, so take care when deciding and factor this into your build costs.

5. Add an Two-storey Oak Extension for Real Wow-factor
A once-dated bungalow has been transformed with a two-storey extension supplied by Oakwrights. Extensive glazing cleverly modernises the exterior while delicate stone cladding make it look like it has always stood there.
6. Design a Sympathetic Extension to a Period House
Oak frame structures are often chosen to match existing period homes, timelessly adding to their existing charm, but attention to detail is absolutely key. Take time to match materials, architectural forms and historic quirks.
By choosing an oak frame structure, the homeowners of this Grade I-listed 16-century cottage were able to double the size of their property in a sustainable and natural way.
31 tonnes of oak supplied by Living Oak were used, while efforts to tie in the new addition with the existing house – by using a similar roof tile and brick stain – make this project undoubtedly special.
7. Connect to an Existing House with a Glazed Link
This Border Oak garden room has been connected to the main house with a glazed link. This adds a contemporary finish and extra natural light, while not disturbing the original house's structure too much.
8. Show off and Create Character
The original sections of this 17-century home were painstakingly restored while a contemporary full-glazed oak extension was added to allow as much of the original house to show through as possible.
9. Matching an Oak Extension to a Semi-detached House
While it might not seem to be a natural fit, adding an oak extension to a semi-detached house is absolutely possible. Inter- and post-war houses are often lacking in any identifiable charm so introducing a new timber section is an inspired choice.
This large kitchen extension was framed with oak, providing extra living space as well as some much sought-after character for this style of home.
10. Mix Traditional Exterior Styles with Contemporary Interiors
Planning permission may dictate what the outside of an extension looks like, but you can be completely in control of the interiors to suit your own lifestyle.
For example. this two-storey oak extension was clad to match other traditional Lake District homes, including it's perpendicular farmhouse. The result is an extension which looks as if it has always stood there, but the open-plan interiors give away it's contemporary roots (show below).

13. Show Off the Wow-factor Elements of Oak Frame
Vaulted ceilings are a wonderful feature in oak frame extension design, as this large addition proves. The large timber spans have been left exposed to really make an impact when contrasted to the other low-ceilings of the existing cottage.
The timeless appearance of oak is also beautifully paired with the modern pendant lights.
14. Extend in Oak During a Barn Conversion
During the conversion two timber-framed barns, one had to be demolished over many weeks with each piece of timer logged and transported to Border Oak’s workshop. Some of the original timbers were salvageable and could be incorporated into the new frame which was then linked to the other using a glazed break.
Contemporary styling inside also beautifully highlights the character and charm of both buildings.
