If you’re planning a self-build house and researching construction materials, cross-laminated timber (CLT) is well worth considering. It’s gaining traction in the UK and worldwide for its sustainability, speed of construction and modern aesthetic.
But is CLT right for your project? In this guide, we break down the benefits, considerations and how to find a specialist architect.
What is cross-laminated timber?
CLT is an engineered wood panel made by gluing layers of timber at right angles. These solid panels are incredibly strong and can be used for floors, walls and roofs.
It’s a structural material – not just a surface – meaning CLT can replace traditional construction methods like brick and block or steel framing in a self-build home.
Why is CLT becoming more popular?
Originally developed in Austria and Germany in the 1990s, CLT has become widely used across Europe and beyond. It’s especially popular in:
- Scandinavia, where timber buildings and low-energy homes are common
- North America, where off-site construction is on the rise
- Australia and New Zealand, where remote builds benefit from faster assembly
- The UK, where CLT is now used in homes, schools and even mid-rise residential blocks
Although still a relatively new choice for UK self-builders, CLT is gaining momentum – especially among those aiming for low-energy, eco-conscious homes.
The benefits of CLT for self-build homes
1. Fast construction
Because CLT panels are made off-site and arrive pre-cut, your home can be assembled quickly – often in just a few days. This can dramatically reduce time on site and the potential for delays.
2. Sustainable and low carbon
Timber is renewable and stores carbon. Compared to concrete or steel, CLT has a far lower environmental impact. It’s an excellent choice for sustainable self-builders aiming for Passivhaus or low-energy performance.
3. Design flexibility and strength
CLT is strong, stable and allows for large open-plan spaces with fewer internal supports. It performs well in wind and seismic zones and can meet strict fire safety standards due to its predictable charring behaviour.
4. Beautiful timber interiors
One of the most attractive features of CLT homes is the natural, minimal interior. Many designs leave the timber exposed for a warm, modern look – no plasterboard or paint needed.
Cost of cross-laminated timber?
CLT can be more expensive than brick-and-block methods on a purely material basis. However, the overall cost can be competitive when you factor in:
- Faster construction time
- Reduced labour costs
- Fewer delays and on-site errors
- Lower long-term energy bills (when well insulated)
Tip: CLT may not suit projects where major changes are expected late in the process. Its precision-manufactured panels require detailed planning up front.
Key considerations
- Design certainty: CLT works best when your layout is finalised early in the design process
- Specialist knowledge: Not all builders are familiar with CLT – working with an experienced team is essential
- Regulations: Your design still needs to meet UK Building Regulations, particularly around fire performance, airtightness and insulation
Is CLT right for your self-build?
CLT is a great option if you’re looking for:
- A sustainable, low-carbon home
- A quick and efficient construction process
- A modern home with natural materials and clean lines
- Long-term performance and energy savings
It’s particularly suited to self-builders who value both design quality and environmental performance – and are ready to commit to their vision early on.
