Timber Frame Extensions: A Faster, Smarter Way to Build
A quieter construction method with lower impact and higher efficiency — why more homeowners are turning to timber frame extensions for their next project.
“We wanted more space... but without losing our sanity in the process.”
It’s something we hear often. Planning a home extension can feel overwhelming — long timelines, overlapping trades, brick dust in the hallway. It’s no wonder so many people put it off.
But there’s a better way.
At AM2 Architects, we’ve been working with clients to design and deliver on-site timber extensions that are faster, cleaner, and more energy-efficient than conventional methods — using systems like SIPs (Structural Insulated Panels) or traditional timber frames.
What Is Timber Frame Construction?
A timber frame extension is built on-site using panels that are manufactured off-site and delivered to your property. These can be SIPs or pre-cut timber frames — both offering excellent speed and performance.
This isn’t modular (no cranes or pre-built pods), but it’s highly efficient. Once groundwork is complete, the structure can go up in just a few days.
Think of it as a carefully assembled kit, designed with precision and built to last.
Why Choose Timber?
1. Faster On-Site Build
Most of the preparation happens before materials even arrive. That means fewer delays and a smoother, more predictable build process.
2. Less Waste, Less Mess
Compared to traditional brick-and-block construction, timber systems are cleaner, quieter, and more controlled. Ideal if you're living on-site during the project.
3. Naturally Energy-Efficient
SIPs and well-detailed timber frames offer impressive insulation and airtightness — meaning better comfort and lower energy bills from day one.
4. Design Flexibility
Timber is adaptable and works well with a range of architectural styles. Whether you’re planning a kitchen extension, garden room, or double-height space, the possibilities are wide open.
5. Sustainable at Its Core
Timber is renewable, lightweight, and has a lower embodied carbon than most conventional materials. With the right design and construction, it’s a future-friendly choice.
Not Modular — And That’s a Good Thing
It’s a common question: “Is this modular?”
No — and for good reason.
Modular extensions are built off-site as whole rooms and craned into place. Timber frame extensions, on the other hand, are constructed on-site, allowing for:
Better integration with your existing home
More freedom in design
Higher quality detailing
It’s a flexible approach that puts design first.
The Architect’s Perspective
At AM2, we believe construction should serve the design — not the other way around.
“Timber doesn’t just build faster — it builds lighter. Lighter on the land, lighter on your daily life, and lighter on stress during the process.”
— Angel Gonzalez, AM2 Architects
We don’t push one system over another. But when time, sustainability, or energy performance matter — timber often makes a lot of sense.
Frequently Asked Questions – Timber Frame Extensions
-
Timber frame extensions are built on-site using pre-cut panels like SIPs or timber kits. Modular builds, by contrast, are entire rooms or sections constructed off-site and craned into place. Timber allows more flexibility in design and integration with your existing home.
-
Yes. Modern timber systems like SIPs and engineered frames are incredibly strong, well-insulated, and built to last — especially when designed and detailed properly.
-
Once the groundwork is complete, the timber structure can be erected in just a few days — significantly faster than brick-and-block builds, which can stretch over weeks.
-
You might. While the upfront material costs may be similar or slightly higher, you can often save on labour, site time, and waste. Faster builds also reduce disruption and rental costs if you're living elsewhere during the project.
-
Yes. Systems like SIPs offer excellent airtightness and thermal performance — reducing heat loss, lowering energy bills, and creating a more comfortable home year-round.
-
In most cases, yes. Timber frame is very versatile and works well with a wide range of house styles — from contemporary garden rooms to traditional two-storey additions. We tailor the approach to your property.
-
Timber is a renewable resource and has a much lower embodied carbon footprint than traditional masonry. Combined with good insulation and airtight detailing, it’s a great choice for low-impact, future-ready homes.
