Foxtail Oak

OAK FRAMED Extensions

Using the beautiful and natural grain of oak wood, we can create an extension to your home that is at one with the peaceful tranquillity of your garden. Our first step is always to visit your home, which allows us to survey the space and discuss your ideas and requirements in person. We can advise on the best options to create additional living space while maximising your garden.

Frequently ask questions

Typically, adding an oak frame extension may fall under ‘permitted development rights,’ which means you won’t need planning permission. However, some exceptions exist, especially if you’re in a conservation area or your property is listed. It’s always best to consult with local planning authorities before beginning work.

Oak is a premium building material that combines beauty, strength, and durability. It is resistant to decay and provides excellent insulation properties. Furthermore, the aesthetic appeal of an oak frame building is unmatched, with its unique grain patterns and warm tones.

If you’re wondering about the cost of an oak frame extension, it can vary wildly based on several factors including size, design, finish, and location. As a rough estimate though, in the UK, you can generally expect to pay from around £2,500 per square meter. This can change due to changing goods pricing, location and finishing, but should help give you a very rough guide price.

Oak is a highly sustainable and eco-friendly building material. It acts as a ‘carbon sink’, absorbing CO2 from the atmosphere as it grows and then locking it away even after it’s been turned into timber. As such, building with oak can significantly reduce your carbon footprint.

Flat roofs are entirely possible with oak frame extensions and can provide a sleek, contemporary look to your extension. They also allow for adding roof lights or glazed gables to increase natural light in your structure.

The timeframe for constructing an oak frame building will depend on the complexity and size of the project. However, typically, the process can take a few weeks for a simple garden structure to several months for a whole oak-framed house.
