We are proud to say that Sand Castle on the Beach was designed by the distinguished Wisconsin born architect, John Randall McDonald. He was a great admirer of Frank Lloyd Wrights' Prairie School of Architecture. John Randall McDonald was considered an "Organic Architect" for his appreciation of the elegance of our natural environment thereby heightening his sensitivity to nature.

In 2005, Sand Castle on the Beach was the first hotel on St. Croix to install a 10 KW battery backup solar power system and we have an ever-expanding solar grid for both the hotel and Beach Side Café.

At Sand Castle on the Beach, we strive to be as 'green' as possible! We recently completed the expansion of our solar capacity to upwards of 63 KW! This means we are 50% solar powered!
