As homes get busier and lifestyles change, many of us find ourselves in need of extra space. Whether it’s to create a home office, a bigger kitchen, or an extra bedroom, building an extension can be a practical way to make your home work for you.
One of the options becoming increasingly popular in the UK is the timber frame extension.
A timber frame extension is exactly what it says on the tin: a structure built using a timber frame as the main load-bearing element.
Timber has been used in construction for centuries, but in modern extensions it combines traditional craftsmanship with modern efficiency. If you’re planning to expand your home, this could be the right mix of speed, style, and sustainability.
Timber Frame Extension Vs Brick
When you’re choosing how to build your extension, the decision often comes down to timber frame vs brick. Each has its pros and cons, and the right choice depends on your goals.
A timber frame extension is quick to build. The frame is pre-made off-site and then assembled quickly once delivered. Less mess and noise at your home and shorter project timelines overall. Ideal if you want to minimise disruption to your daily life.
On the other hand, traditional brick extensions take longer to build as there’s more on-site work. The materials are heavier, the drying time is longer, and construction is more affected by bad weather. Brick is durable and familiar, but takes more time and labour, which can increase your overall cost.
When it comes to insulation, timber frame extensions perform better. The structure naturally supports airtight building methods, which can lead to better energy efficiency and lower bills over time. Brick is solid but needs extra insulation materials to match the performance of timber.
So if speed, thermal efficiency, and modern design flexibility are important to you, then timber might be the way to go. But if you want a traditional look with high soundproofing, then brick could be worth considering.
Timber Frame Extension Foundations
So, do I need a full foundation for a timber frame extension? Yes, you do. Just like any other type of extension, a timber frame needs a solid base to support the weight and keep the structure stable over time.
Foundations for a timber frame extension aren’t that different from those used in brick builds. They still need to meet building regulations and be designed based on your ground conditions. A structural engineer or builder will usually carry out a site assessment to determine what kind of foundation is best for your property.
This can include strip foundations, trench fill, or even concrete slabs. The main difference is that timber is lighter than brick, so sometimes the foundation can be slightly simpler or shallower. But this depends on your location, soil type, and the size of the extension.
Getting the foundation right is key. It not only supports the weight of the timber structure but also keeps it dry, level, and protected from future movement.
Footings For Timber Frame Extension
Footings are a vital part of the foundation system. They help spread the load of the structure and stop it from sinking into the ground. With a timber frame extension, footings usually need to be set deep enough to reach stable ground, especially in areas with soft soil or where trees are nearby.
In most cases, concrete footings are poured into trenches dug around the extension footprint. These are then filled to form a solid base for the walls or slab to rest on. Depending on the design, you might also have reinforced steel added to the footings for extra strength.
Because timber frames are lighter, you might assume the footings can be smaller, but that’s not always the case. Building control will still expect the work to follow the same standards as any other extension type. Your builder should handle this part carefully to avoid future issues like subsidence or cracking.
Timber Frame Extension Cost
One of the biggest advantages of going with timber is how it can reduce time on site, which helps cut down on labour costs. But when it comes to timber frame extension cost, you need to look at the full picture.
On average, a timber frame extension in the UK can cost anywhere from £1,500 to £2,500 per square metre, depending on the design, location, and level of finish. While the actual timber structure might be cheaper than bricks and blocks, other factors like insulation, windows, cladding, and roofing still affect the total cost.
And if you go for high spec or need complex groundworks, the price can add up quickly. But many homeowners still find timber extensions are cost-effective, especially because of the quicker build time and lower bills over the long term.

Is A Timber Frame Extension Right For You?
A timber frame extension is a great option if you want a quick, energy-efficient, and sustainable way to add to your home. It works for modern and traditional styles and can be tailored to your existing property.
It’s also perfect if you want to keep the disruption to a minimum. Since so much of the work is done off site you won’t be living in a building site for weeks or months.
But you still need to plan carefully, make sure the foundations and footings are designed properly and choose experienced builders who know how to build with timber frames.
Conclusion
Whether you’re looking for a small extension or a full redesign of your home, timber frame construction is a fresh and practical way. It’s fast, efficient and surprisingly versatile. By understanding the process from foundation to finish you can make an informed decision that adds comfort and value to your property.
