This is what you need to know about oak framed houses

An oak framed house designed by Oakwrights.

They certainly give that wow factor, but let’s explore the full facts about oak framed houses to put you fully in the picture.

We examine the build options and look at why oak frames are so desirable, before investigating their pros and cons, their costs, and the source of oak used in the UK building industry.

 We then feature examples of some beautiful oak framed buildings from leading specialist firms.

Build options and desirability

Building with an oak frame and featuring exposed beams gives a house immediate character, and the style works well with traditional or modern houses. A living, breathing building material, oak’s aesthetic qualities add warmth and ambiance to a home.

Being a strong, durable material means that an oak framed house can offer design flexibility. It’s ideal for creating large, glazed spaces and is a popular choice for many self-builders. Oak can create an eco-home with the correct insulation system to achieve the required airtightness levels. Newly cut timber is used to build the frames as it’s flexible.

Seasoning

Oak frames shrink as they dry out, which is known as the seasoning process. While it takes many years, most shrinkage happens in the first two years when the timber develops cracks and settles. The jointing and pegging will minimise this and the structure becomes stronger as a result. An oak frame could last for over 200 years – typically, if a house is oak clad externally it will last 2-3 times longer than treated softwood.

Oak framed building techniques

The oak frame can be exposed internally and externally if desired. The main internal walls, floor joists, roof members, and trusses can be exposed, with insulated render panels placed between the timbers. Alternatively, an oak frame can be hidden within the structure.

Oak frame suppliers may use machine cutting or a traditional handmade method. While computer cutting is more accurate and allows for complex designs to be created, it gives the wood a slightly different appearance. Oak is, of course, a traditional UK building material, and houses with timber frames have been built here for centuries, with many houses constructed with timber from dismantled ships.

Advantages of oak framed houses

Oak is:

  • Resistant to insects and fungal invasion
  • Weatherproof
  • Almost maintenance fee
  • Sustainable providing that it’s correctly sourced
  • A wood that ages well
  • Great for large open spaces – interesting structural design is possible due to the strength of oak, as a frame can support the whole house, so there is no need for internal load-bearing walls.
  •  Fast to build in pre-constructed kit form, as the frame can be constructed offsite which reduces the effects of bad weather delaying the build, unlike a brick-and-mortar building.

Disadvantages of oak framed houses

  • They can be challenging to light internally
  • It may be necessary to design around beams

Is oak frame expensive?

Buying oak can be a costly exercise. It can cost in the region of £1,696-£2,120 per m2, but it can be £1,000 per m2 according to Homebuilding.co.uk’s oak frame guide which says that the frame’s build cost can be between 18-33% of the total build cost.

How long do oak framed buildings last?

Oak is an extremely durable wood, and an oak frame house could last for over 200 years. The oak frame building technique is centuries old and there are many examples of houses built in this way still standing and showing no signs of falling down!

Sources of oak

Most oak used in the UK for building with comes from sustainable forests in Germany or France, where replanting schemes are carried out. Trees are harvested at around 80 years old. English oak is more expensive and because it doesn’t tend to grow as tall and straight, is better for making furniture than building houses.

Green oak

This is newly felled timber with a high moisture content which makes it easier to work with. After around five years it becomes too hard to machine – the skill of the craftsman is in knowing how it will shrink and create the joints, so they get tighter as the timber hardens.

To achieve this, the pegs fixing the joints are tapered and the holes between the timber are often offset, allowing the shrinkage to bring them together so that the joints become tight. Glazing and joinery also take into account the shrinkage process.
