engineered hardwood if below grade, over concrete, or a humid climate.

my 1999 built home is oak kitchen floor and oak cabinets but I have a dark contrast counter.. consider adding hardware to the cabinets to break up the oak wall.. Did not ask, but items on top of cabinets is distracting and does not tell a cohesive story.. Reminds me of college guys and their beer bottle display in their apartments and who gets to dust all of that stuff?

I think these are bambo. Very nice.

It does look like brazilian cherry, or some other type of exotic species. If you have heat registers in your floor, pull one up to look at the profile. You should able to tell if it is engineered, laminate, or solid wood. Solid will be one piece of material all the way through, engineered has a multi-ply core, with a layer of hardwood veneer on top, and laminate will have an mdf core with a picture of wood on the top. Just from looking at the picture, I would guess it's either engineered or solid. It doesn't seem to have a repetitive pattern that you'd typically see in an engineered product. If it's a solid product, it is definitely prefinished, as opposed to site finished. The piece perpendicular to the rest of the floor looks like oak with a dark reddish stain to coordinate with the other material.
