The length is in total 145", but from the framed wall (on the right side of the photo) to the refrigerator side (left end), it is more like 133".
All drawers are 24" standard depth. There is a typical half-framed wall behind the tile on the stool side. The depth of the peninsula at the deepest point behind the cooktop is approximately 43", and at the left end is about 35" Deep. This allows for 15" of surface landing BEHIND the cooktop at the deepest/centered point. It is better looking and has a built-in safety issue around the cooking surface.
