It seems to be Teak, which is a quite expensive wood. Lots of Yachts and Boats are made of Teak and it is used widely on decks, so, I still dont understand what your question is? What you are saying, is that because of the electrical and AC Vent, you need to drop the ceiling? Do you have straight walls/ceiling? can the wood be attached to the existing ceiling? The Carpenter installing the wood, could just lower the AC Vent and what kind of electrical are you talking about? The ceiling can lights?

Hi again- I'm an Aussie and the term 'wood burner' means a metal box with a glass door on the front and in the situation where you have a 'double sided wood burner' that means two glass doors on each end. A wood burning fireplace open either side between two rooms is a different thing. Sorry about the confusion. I looked into building one of those in brick and was strongly advised to place a glass panel on one side ( as Ironwood has pointed out) the natural draughts that move through your home will take the smoke with it. A piece of glass will prevent this from happening.

Jitesh, for our remodel we picked maple hardwood floor throughout the living room, dining room, hallways, stairs, and bedrooms. We like the warmth and look of real wood. We use tiles in the bathrooms because of all the water.

Photos would be helpful.
