Timber
Margerita deKwant of Pentarch Forest Products explains the magic of yakisugi.
What is this construction material?
This is yakisugi – charred Japanese cedar. Architects and builders have used sugi, Japanese cedar, in homes here, yet until now the timber has stayed under the radar. What makes it remarkable is the way fire transforms it into something new – yakisugi.
Why is it charred?
Through controlled firing, yakisugi gains impressive durability in minutes. Intense charring removes the need for chemical stains or synthetic paints. Our charring partner Chartek has a specialised charring facility in Christchurch where all our timber is processed. In partnership with Motueka- based Natural House Company, natural oils – made from earth pigments – enhance sugi’s tactile character and rich colour. The fully charred black surface delivers the highest durability and thermal performance, as seen in centuries-old Japanese shrines. As the timber is brushed back to reveal more texture, the effect becomes three- dimensional; surfaces seem to move as light and viewpoint change, while colours shift against different materials. For external cladding, maintenance requirements often decrease over time, making yakisugi even more cost-effective over time. Inside, its potential is broad – feature walls, battens, screens, architraves, ceilings, furniture and bespoke joinery. The different profiles and finishes create dramatic exteriors and luxurious interiors that shift with the light.
Is it eco-friendly?
At Pentarch Forest Products, we call sugi “timber with a conscience”. It sits so well in New Zealand, where designers, builders and homeowners are seeking more eco- responsible materials. Around 68 per cent of Japan is covered in forest, and thoughtful stewardship means careful planting and harvesting cycles that protect the forest, reduce waste and minimise transport impacts. Thanks to efficient marine freight, the carbon footprint of shipping sugi compares well with other building materials. With sugi sustainably grown in Japan and finished here in New Zealand, it remains an accessible alternative.
Where can we get some advice?
Pentarch Forest Products has opened New Zealand’s first dedicated sugi showroom in Piccadilly Arcade in Tauranga. The team also provides expert advice, supplies nationwide and operates a showroom at Residium in Parnell, Auckland. The goal is simple: to spark the imagination of anyone thinking about their next project and to allow visitors to touch, see and specify the product. We’re excited to see what local architects and builders will create with it.
