It’s difficult to pin down a precise definition of what ‘natural’ means, but for us, it starts with avoiding petrochemical derived materials and in particular, plastics.

In simple terms, ensuring that every component we make will remove more carbon from the atmosphere than it takes to make it. We also consider in detail how to minimise operational energy use and what happens when a building is altered or decommissioned, so that components can be reused.

Cellulose based natural materials such as hemp shiv and timber will last indefinitely providing the moisture content is maintained at less than 20%. There are examples of buildings made with hemp dating back to the 17th century in Japan and many more examples of earlier timber buildings.

It’s worth noting that most conventional construction involves a hybrid of masonry and timber. These buildings last for as long as they are properly maintained.

We have carried out (and passed!) extensive fire tests at the Building Research Establishment. Further details available on request.

We have developed a patented system of removable timber pegs with T&G cones to secure each panel. This allows rapid assembly and disassembly. Joints are taped to ensure airtightness.

Yes! The system is designed so that wall, floor and roof panels can be demounted and reconfigured.

BIM is an acronym for Building Information Modelling. We print a QR code on everything we produce to track material, design, and production information. Together with a detailed digital twin of the whole building, this allows us to plan for cost effective maintenance, alterations, and re-use.

Yes. Mortgage and insurance companies have varying requirements, but typically need to see a building regulations completion certificate and latent defects insurance. We can help arrange this through providers such as Premier.

This question is obviously impossible to answer without an agreed design and specification, but the system allows for a wide range of breathable interior finishes and exterior cladding options, with a corresponding cost range.

There are also choices for the levels of insulation and everything else that goes into a building, such as windows and doors. Our components would typically comprise around 1/3 of the total build cost which, for a two-storey dwelling this might start at around £3,000/m2.

We offer an assisted self-build option, where we assemble the building envelope, internal walls, floors, and roof. Everything else, including plumbing, electrics and internal finishes can be done by yourself or local tradespeople with the option of ongoing site supervision.

This is a complex subject in building physics, but in simple terms it’s the difference between a vapour open or vapour closed thermal envelope. More information is available here.

The requirement for increased air tightness in buildings has resulted in some cases to a reduction in indoor air quality. This is because airborne moisture can’t easily escape and collects on internal surfaces as condensation, allowing microbial growth.

Using natural materials such as hemp and timber means that the indoor environment is free from VOC’s but also maintains relative humidity at a level ideal for human health.

For residential buildings we are limited in the UK to the upper floor at no more than 11m above ground level. For non-residential uses we can build up to 8 stories with an integrated engineered timber primary structure.
