1. Sympathetic Extension to Grade I-listed House

By choosing an oak frame structure, the homeowners of this 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. 

2. Oak-framed Garden Room

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.

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. 

5. Two-storey Oak Extension to a Farmhouse

You’d be forgiven for thinking this oak two-storey extension has always stood beside the renovated perpendicular farmhouse. Set slightly back from the original building, the design of the new space’s exterior is reminiscent of the traditions of the Lake District, where it resides, while a contemporary open-plan interior lies inside.

Clad in weatherboarding, this oak-framed extension by Westwind Oak features large double-height glazed doors reminiscent of a converted barn opening in order to sit naturally alongside the established farmhouse-style building.

Oakwrights’ GreenRoom designs are an effortless blend between contemporary and traditional styles. With a tiled roof and copious amounts of glazing, adding a sunroom creates a space which is naturally bright without the seasonal limitations of conservatories.

Vaulted ceilings are a wonderful feature in oak frame extension design, as this large addition proves. The timeless appearance of oak is also beautifully paired with the modern pendant lights. 

9. Restoring and Adding an Oak Frame Extension

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.

10. Open an Older Home to the Garden

As beautiful as they may be, older homes are frequently plagued by warren-like layouts and small windows, so adding a complimentary oak framed structure with plenty of glazing can often be a sympathetic yet modern solution. This Prime Oak extension includes an awe-inspiring glazed gable while french doors to the side elevation lead to the outdoor spaces.

11. Three-storey Oak Extension

When demolishing an 18th-century 'wing' to this Grade II-listed property which had become structurally unsound, Oakwrights design and built this magnificent three-storey extension.
