“This year we’re seeing a resurgence in the use of oak as a building material,” says Andrew Christopher, owner and managing director of Cotswold-run Mitre Oak Ltd. “It’s organic, sustainable, and the wood perfectly complements the surroundings of a countryside home.”

Andrew reveals everything you need to know about designing your own handcrafted oak framed extension and shares how it can breathe new life into your property.

A: Oak is an extremely flexible building material, making it easy to style and shape a frame into any design you choose. It instantly adds warmth, suits any style of house; contemporary or traditional, and will make a knockout architectural feature.

We handcraft all of our frames, using only certified, sustainably sourced European Oak. Oak absorbs greenhouse gases and locks in CO2, helping to reduce emissions and care for our planet. An oak framed extension is a great way to make your home extra-special, create the additional space you need, and add value to your property.

Oak is also an amazing natural insulator. You can install panel insulation systems and temperature regulating glass, to design a space that can be used all year round.

A: Anything you want, the possibilities are endless. You can use your extension to create a home office, workshop or studio. It’s also the ideal place to set up a home gym or garage. You can even use it to extend your kitchen, dining room or as additional living space for you and all the family. We build porches, garden rooms and orangeries as well.

One of our clients wanted to enhance his outdoor space by building a sheltered dining area. We designed a bespoke Oak Pergola, where he could host BBQs, relax by the pool and entertain guests.

A: Our expert joiners use traditional carpentry techniques to craft your frame and strengthen and lock the joints. These are methods that were used on many of the old buildings you see today and will ensure your extension is strong, weather-resistant and long-lasting.

As the oak ages, it weathers to a striking silver-grey colour or you can choose to preserve its honey colour with the use of protective oils.

Q: Will I need planning permission for my oak framed extension?

A: There are lots of home improvement projects that don’t require planning permission before installation. Our range of garden office kits and two of our oak framed garage kits are Permitted Developments (PD), so in most cases, you won’t need planning permission to build them.

However, if you live in a listed or period property, it’s always best to check with the local authorities first. We provide an adept planning service, using our experience of the region and years within the industry, to provide you with the building regulations that you need.
