This seems to be the back side of the open glass shelves I like so much. Since the designer did not answer the questions regarding width I am going to estimate. The end of the counter and the island seem to be on the same line. The island looks like it has back to back 24" deep sections. that makes 4'. Then, you have the 24" depth of the cabinet where the sink is so now we are up to 6' and then you need the space beween the counters along wall and island. that puts my guess at a minimum 8' width, more likely close to 9' - anyone else want to hazard their best estimate?
