Passive House

What is Passive House?

Passive House is an international high-performance building standard designed to drastically reduce heating and cooling energy consumption. 

We believe it is the best possible standard of building for our clients to invest in and all our practitioners are certified and experienced in delivering certified Passive House Projects.

Prefab, Engineered & Mass Timber

What is Engineered Timber?

Engineered timber is the name for special types of wood products made by joining smaller pieces of wood together to create materials such as glu-lam or cross-laminated timber.

This efficient process creates a strong, versatile and sustainable structural material that is perfect for low energy buildings and prefabrication.

Why we use Engineered Timber and Prefabrication

  • Sustainable and Renewable – Made from fast-growing trees, engineered timber stores carbon and reduces reliance on concrete and steel.

  • Strong yet Lightweight – Mass timber supports large spans with fewer structural elements, lowering foundation requirements.

  • Naturally Insulating – Timber’s thermal performance helps create energy-efficient buildings, ideal for Passive House standards.

  • Rapid, Precise Construction – Prefabricated components are manufactured off-site using 3D models for fast, accurate on-site assembly.

  • Healthy and Beautiful – Warm, natural timber interiors enhance comfort, calmness, and indoor air quality.

  • Flexible and Creative – Custom forms, curves, and finishes are achievable with CNC machining and advanced fabrication techniques.

  • Quiet and Low-Impact – Timber buildings reduce noise, dust, and onsite disruption during construction.

  • Safe and Predictable in Fire – Oversized timber elements char on the outside while protecting structural integrity.

  • Long-Lasting Quality – Detailed craftsmanship and prefabrication ensure precision, durability, and reduced maintenance over time.
