Emerald Bay
Emerald Bay is a 12-story oceanfront condominium at 151 Crandon Boulevard in Key Biscayne, completed in 1980 as part of the Key Colony complex, one of four sister towers developed by Fritz Scharenberg (alongside Tidemark, Oceansound, and Botanica). The building comprises 285 residences and is known for its distinctive pyramid-style architecture, set on a sloped design intended to maximize privacy and unobstructed water views for upper-floor units. As a full-service, guard-gated building within Key Colony, Emerald Bay offers 24-hour concierge and security, direct beach access, a heated pool and jacuzzi, a fitness center, and party and game rooms, with residents also enjoying Key Colony's shared resort-style amenities, including 12 tennis courts, additional pools, and on-site retail. Key Colony's original landscape design earned a National Association of Home Builders Grand Award in 1980, and the complex remains one of Key Biscayne's most recognized residential developments. The building sits within Key Biscayne's low-density, beachfront residential enclave just south of Miami, prized for its village character and proximity to Bill Baggs Cape Florida State Park.
