Kelly Cross The lower section is 103.5" in length and 54" deep. The L section is 85" long on the longest side, and the short side of the L is 60" length.
Paul Anater The dark wood is either cherry or walnut though I'm thinking cherry. All cabinet makers use different names for their stain colors and since I don't know the manufacturer I can't tell you the name of it. Go to a kitchen show room and ask to see cherry in the darkest stain they have and it will look a lot like this.
The white cabinetry is probably maple. Maple's usually the wood species that gets painted. Just as manufacturers don't have standardized names for stains, everybody calls their paints different things too. In the same kitchen show room I suggested you visit, ask to see their whites. You'll see that most manufacturers make more than one white.
Kelly Cross The dark cabinetry is actually beech with stain/glaze combination and distressing. The white paint is on alder with a glaze and distressing. Alder is also a common wood that gets paint & distressing, mainly because it is a "softer" hardwood and is easier to distress than maple.
Rebekah Zaveloff I venture to guess a Juparan Persia or Santa Cecilia - but I'd recommend showing it to a supplier, the names vary from supplier to supplier and region to region. This looks darker and denser than some of the slabs from those names I've seen over the years.
