It just may be the ultimate beachcomber’s fantasy: a private beach home shaped like a giant seashell. Make that two giant seashells—a conch (dubbed “Queen Conch”) and a nautilus (“Moon Shell”)—designed by architect Eduardo Ocampo. This Isla Mujeres retreat sleeps 4 people (with two bedrooms and 2.5 baths), features a pool that overlooks the ocean, and is a 15-minute golf cart ride from the beach. Additional shell design details include: swirling shell-shaped “headboards” sculpted right out of the plaster walls, shell-trimmed mirrors, shell-shaped soap dishes, and large shells converted into faucets and shower heads. Really. Book your stay here.
