I don't believe this is too tough for someone who has carpentry skills. The hard part is the cut on the Corian countertop and getting a mortise in that looks original. If you look close, you can see where the cut started on the countertop, and the pics don't show any closeup of the resulting 'mortise' which is not a true mortise, but a piece cut off the other portion not used. It really isn't noticeable unless you know to look for it.
We really liked the floorplan when first we got it, but gradually we found ourselves in each other's way, or the dogs were trapped and underfoot with the blocked end.
We feel it is much more livable now, movement from front to back can be done without going around the end of the counter.
If we could afford a newer unit, we would not consider the peninsula floorplan again.
Hope this helps.
