Oak framed vs brick extension - which is best?

Quick summary

A brick extension is generally cheaper upfront, but costs are rising as bricklayers become scarcer, and oak frames can require a big deposit due to specialist skills. Oak is faster to build, saving up to three months, but finding skilled contractors is harder outside Scotland. Both options have eco benefits, with oak being renewable.

When it comes to building your home, making sure it stands up is a big priority. But what frame you buy is a question very much in the air.

Do you choose the more traditional brick extension? Or do you go for the more unique oak frame - a choice that is slowly gaining prominence in the UK? And most importantly, is there even a difference between the two?

Cost

A few years ago, this would have been a very cut and dry answer, as brick has traditionally been cheaper than oak to build with. That’s because oak is a specialist material, so many professionals put up their prices when dealing with it.

However, this is starting to change, as bricklayers are becoming more scare in the UK, and so the price of maisonry is going up. This means the prices are balancing out, though probably not in a way many homeowners will be happy about. There are also some that argue that the speed factor of oak can help reduce other costs (more on this in a second) so can work out cheaper overall. Although, it’s also worth noting that because of the skill that goes into oak frames in the early stages, they tend to require big deposits up front - so can cause cash flow issues.
