The wood shown in the facade appears to be Ipe. Ipe is a Brazilian Hardwood that is actually 10x harder than Redwood. Ipe can be found in farmed raised regenerative forests. It is maintenance free and without any chemical additives. The natural properties of Ipe help resist termites, mold and wood rot. A properly design wall with a vapor barrier, stainless steel screws and other details would help this system stay intact.

Thank you!
