Timber-Frame Construction
Exceptional Strength and Durability
Solid reinforced concrete walls withstand extreme weather, resist rot and rust, and are designed for long-lasting performance.
Continuous insulation and thermal mass reduce heating/cooling costs and maintain stable indoor temperatures
Superior Energy Efficiency
Concrete core and treated insulation provide multi-hour fire protection, enhancing safety.
Fire Resistance
Lightweight forms simplify assembly, reduce construction steps, and shorten build times.
Fast and Efficient Construction



Timber frame construction is one of the oldest and most established Modern Methods of Construction (MMC) and is used in over half of all new homes in Ireland today.
TSD is a specialist timber frame designer operating across Ireland and the UK, delivering designs for leading timber frame companies including Eco Timber Systems, Shoalwater Timber Frame, Long Life Structures, Ecotech Homes, among others. We have experience across a wide range of systems, including factory-built MMC frames, stick-built (on-site) structures, and niche applications such as post-and-beam.
Our work is grounded in a clear understanding of timber behaviour, modern off-site manufacturing, and site requirements. We focus on safe, economical structural solutions, aligned with the performance demands of today’s low-energy homes.
Whether you’re an architect, developer, or self-builder, our designs integrate seamlessly with your chosen supplier and meet all relevant standards. We deliver projects ranging from one-off homes to large multi-unit and commercial developments, with thousands of successful timber frame designs completed over the past two decades.
Fast build times thanks to off‑site manufacturing and rapid on‑site assembly
Superior energy performance with high insulation levels and reliable airtightness
Lower running costs due to reduced heat loss and improved thermal efficiency
Sustainable material choice using renewable timber with low embodied carbon
Consistent quality from factory‑controlled production and precision engineering
Design flexibility allowing a wide range of layouts, spans and external finishes
Reduced foundation requirements because timber‑frame structures are lighter
Cleaner, quieter sites with less waste, fewer deliveries and shorter disruption
