Oak Extensions

Oak Extensions

Whether or not you seek to match an existing oak framed property, an oak extension from Green Oak will enhance any home.

You can trust us to ensure that the extension is not only a stunning place to live in; it will also be highly practical, in terms of easy living and insulation efficiency, to reduce fuel usage and increase your comfort all year round.

Some of our customers are looking for a relatively small extension; others want to double the size of their home or more. The Green Oak team will help you with every detail if you like; from designing the most beautiful and effective shapes and configurations, through to which flooring would best complement the loveliness of the building.

Please take a look at some of our projects, and when you are ready to talk, if you like we can arrange for you to visit one or two of our customers’ homes, and meet those who trusted us to create them. This way you will be completely confident that we are the right company for you.

OUR PROCESS

From concept to completion, our team supports your oak framed journey at every stage

Planning Design Build After service
Planning
When we come to survey your property, we start by listening to you. We discover how you envisage your property will look, as well as how you plan to use your new space. We will talk foundations, size, position, insulation, glazing, security and more, to ensure every detail is covered. We adhere strictly to UK building regulations throughout, and advise on feasibility. If you need planning permission, we will play our role in helping you to gain it.

Design
Once we have a really clear idea of your vision, we set about designing your unique masterpiece. We create drawings to demonstrate our thinking and discuss these with you. We work out which frame types to use, and what kind of traditional joints will be the most effective and aesthetically pleasing. We decide the style of trusses needed to do the best job, how to insulate your space, and the most compatible roofing style.
Build
We take responsibility for all works, including groundworks, electricals, plumbing, glazing and finishing. At the start of the building process, we select every piece of green oak timber individually, by size and by understanding how it needs to perform within the whole structure. We use only traditional carpentry tools and techniques, laying out the pieces like a jigsaw beforehand, matching pieces to perfection. All cutting is done by hand, and we use traditional oak pegs to join each part of the oak frame, so they can mature and settle into their own unique form.
After service
One of the best things about green oak is that as it matures it dries out, becoming more and more beautiful with its own unique identity. It will not shrink in length, so the structure will remain solid for many hundreds of years. You may have concerns however, and we are always on hand to offer advice. You will probably need to redecorate after around two years, when the building has settled and we can organise this for you if you wish. We tend to stay in touch with our customers over the years.
