Budget considerations are of course one of the primary factors for anyone undertaking an oak frame self build project whether it’s a new build oak frame or a timber frame extension. ‘How much will it cost?’ is therefore a question which will be asked over and over and will almost certainly form a central thread of your project.
The cost of building a New Build Oak Frame House or Timber Framed Extension
Overall build costs for a complete new build oak house typically vary from £1,500 to £2,000+ per square metre (referring to the useable area of the lower and upper floors added together) i.e. for a two storey property times the area by 2. We would suggest that you budget from £1,200- £1,800 per sqm (or £120-£180 per sqft).
For extensions we would suggest budgeting from £2,000 per square metre – don’t forget to add VAT (for UK customers). It is worth noting that guide price is for a complete build based on a contractor doing the work with the timber frame is usually a 20-30% proportion.
If you intend to self build then expect to budget toward the lower end of the scale (although of course it may take longer!). There are several caveats with this guide price including the following key considerations:-
Access:- Difficult access effects the whole build not just the timber frame aspect, but don’t panic if your site is tricky as there is usually a solution for the most extreme cases. We love a challenge at Carpenter Oak Ltd.
- Size – smaller doesn’t necessarily mean cheaper!
- Ground conditions
- Specification ie Kitchens alone can vary from £1,000 to £100,000.
- Design and shape. A house designed with a timber frame in mind from the outset will be more efficient to build. Consider this at the planning stage.
- Complexity of the building and its shape. A ‘H’ shaped will be more expensive to build than a rectangle.
- Good information and knowledge from the architect, builder, timber framer and the rest of the team you employ.
At every stage your decisions will affect the overall costs, from the complexity of the design to the level of finish. Engaging an architect will almost certainly save you money in the long run. Getting advice from us on the timber frame concept prior to going in for planning will minimise the risk of sending your architect ‘back to the drawing board’.
- A timber frame can be a simple primary structure or a partial one in a certain area of your house. It can incorporate fully raftered vaulted roof spaces, mezzanine floors, balconies and fully joisted areas, all of which will affect the price of the frame. Areas such as the roof structure can be done in revealed oak frame or can be entirely hidden and done by your builder in softwood. This will affect your overall cost to some extent but will vary the value of our work significantly.
- The timber frame is just one element of your overall build cost and can typically range from 15% – 30% of the overall figure.
- All of our frames are unique and so there are no standard price or designs. We do show a variety of designs in our pack however with corresponding frame prices and overall build prices which will help you to get a good sense of the cost. The cost of a frame often ranges from £300 – £500 per square metre.
- As soon as you have architects drawings, we can offer you an estimate for the manufacture and raising of the frame. We generally offer clients a fixed price.
