Treasured for its durability, in recent years this remarkable wood has undergone a revival as a building material. In certain parts of the country rustic oak-framed extensions are now all the rage. The oak framing is combined with large areas of glass, but there is also a wide use of tiled or partially tiled roofs, which suits the style set by the oak beams.

Rustic Oak Interior

Combining traditionally jointed and pegged timber frame construction with ultra-precise machining and finishing means we’ve arrived at unmatched levels of quality and integrity. Modern, yet infused with a certain timelessness, we can apply the traditional rustic oak style to our orangeries, conservatories, garden rooms, kitchen extensions and pool enclosures. At the same time we make beautiful oak windows and doors.

We are proud of the professional way in which we have introduced this product into our ranges in recent years and Oak framed buildings have already grown to fifteen per cent of our turnover since we acquired the County Oak brand. As you would expect from David Salisbury, we have dramatically improved the construction and integrity of these buildings over anything offered by the major competitors.

Our Oak Extensions can be classified into several main types: The Garden Room, The Orangery and the Mansard Roof Extension. The Orangery has a flat roof with a glazed lantern similar to the hardwood orangery, but with the large rustic timber sections you can see in the pictures. The Garden Room has a solid tiled roof possibly with velux windows  and the Mansard roof extension has partly tiles partly glazed roof with more extensive exposed timbers.

You can see examples of all types in the photos on this site and our designers have more examples to show and will be happy to take you through the options.
