This looks very close to a timber called 'Iroko', which is a very stable South African hardwood. It has that lovely deep shine to it. We use this wonderful timber for all of our handmade joinery, the timber is left coated with Osmo clear oil to allow the grain to shine through. The door in your picture appears to be an up and over type, it is unusual for this to be made from timber but that is what it looks like.

Hope this helps
