8'-10'-12' is the usual limitation for any type of materials. Even plain "raw" woodworker's stock doesn't come as large as you're wanting, so I cannot think of a single material that would be able to cover the whole thing without a seam. 140" isn't an island, it's a continent! :~) Are you really sure that such a large piece will add function to your design and not be a constant barrier to be gotten around? Islands typically don't exceed more than 96" in length for functionality reasons, unless the kitchen is more of a galley kitchen with one "wall" of the galley being the island with no uppers.

I like my fruit refrigerated except for bananas which I keep in a bag in a cupboard. I do have a 3 tiered stand that I use for tomatoes, garlic and my car keys but the island has a large wooden bowl that is mostly decorative. I usually remove it when I start to seriously cook. Not sure of the islands dimensions but 40" x 60" seems about right.

ugh.... we are just at this point now and realized that our new counter/breakfast bar is 12' with the sink cutout dead center. My wife is stuck on an undermount and we really wanted granite... we will, of course, be getting a few fabricators to bid it. But is it feasible to do the seam with a cutout at the seam? The front edge of the sink seems a bit vulnerable to me. Also the current layout has the dishwasher adjacent to the sink and I guess we'd need to get the cabinet built with a support at the seam. If we can seam at the sink it would be small, just the length of the front setback (breakfast bar transitions to countertop there)... how well does the bullnose normally line up on a seam? Do they polish it on-site? Are we better off getting used to NOT granite? The 12' counter is not negotiable in our design.

Pllog, Well, we are in both in CA, as some would say! ;) I do agree with your comment about granite being the standard because of its perception as being a luxury item. FrmrsDghtr, WOW!!! Love what you were able to do!!! RosySunnyGal, Our counters are Floating Blue which is a mostly turquoise in white cement matrix color. We were able to pick our slabs at the factory when it was still here in the Bay Area years ago. We have several KDs in our area that had samples of Vetrazzo, Icestone and Fuez to look over. IF you are looking for the wow factor, these will do it. With that in mind, I do recommend that you really like your countertop color because it is a very prominent part of your kitchen. They also aren't cheap and I highly recommend that your installer be someone who knows how to work with this material. Our installation fabricators claimed they did and we had multiple problems with them that we finally had to hire a second company to fix. We looked at all of the green countertop materials, and this was the one that my DH and I were able to agree on despite the price. BTW, I don't include quartz or C-stone in this category. I do recommend that you do an online search for recycled glass companies because there are several others besides the three I mention above. The ones that I have ran across are: Gilasi in the Chicago area, Urbanslabs in SoCal, Vetrazzo is now in the Atlanta area, and more that I have seen around the US. I do recommend if you can using one that is near you because of the weight and shipping cost of the slabs. If you are interested in knowing more or seeing some pictures of my counters, please, PM me.
