Adjustable height counters

While the King family probably does not need this product, I have a classmate who is redesigning the same home for two clients with two very different heights - the husband is 6'2 and the wife is 5'1. You can imagine (as can I since I'm 5'2) that the industry standard counter height of 36" would be a challenge for both of these individuals, and of course for a household where someone is in a wheelchair. Comfortable counter height is based on the individual and exists three inches below the elbow.

So, the obvious choice is to vary the height of the counter tops so each person has a work surface. But what about places like the cook top or a sink?

Voila! Counters on a lift that can accommodate both important stations.
