Luxury Homes for Sale in Key Colony Beach Half Duplexes, Florida Keys, Florida

Introduced in the 1950’s as part of the planned community, Key Colony Beach duplexes are ingrained in the fabric of this idyllic island.

Key Colony Beach is legendary for duplexes, with many finding these charming beach bungalows reminiscent of days gone by. It is exceptionally rare for both sides of a duplex to be owned by one individual or family; therefore, it is more common to hear the term “half-duplex” as opposed to full duplex beach house for sale. Starting on the east end of the island, duplexes are intermingled with single-family homes between 2nd and 11th Streets. Most duplexes are canal front, with standard lot sizes of 60’ or 75’ wide. Half-duplexes will have either 30’ or 37.5’ of canal frontage with a private dock. Only canal front or dry lot duplex options are available in Key Colony, there are not any duplex on the beach for sale. Curious about the particulars of half-duplex ownership? Give me a call today, having owned three half-duplexes in Key Colony Beach, I’m both professionally and personally qualified to answer any questions you may have.

SENSE OF COMMUNITY: Key Colony Beach offers a variety of things to participate in for residents and visitors. Spend the afternoon at the Key Colony Beach 9-hole golf course or bike to a game of tennis or pickleball. Looking for an opportunity to mingle? Join the Key Colony Beach Fishing & Boating Club or Community Association, both participate, support and/or organize many of the annual community events such as the KCB Christmas Boat Parade, Clam Bake, KCB Days, Kids Fishing Tournament and more. When considering a beach duplex for sale, know that plenty of activities are right out your front door. While Key Colony beach does not offer any duplex on the beach for sale, there are plenty of canal front options where you can enjoy marine life activity right out your back door.

CALM LIFESTYLE: Owning a home in the Keys allows you to appreciate a low-key lifestyle, away from the hustle and bustle of city life. With fresh salt breezes, colorful sunsets and star filled night skies, there is no doubt you will find serenity. The laidback community is perfect for those seeking a slower pace of life, a small-town close-knit vibe, where there is time to chat with neighbors. The family friendly environment is ideal for those looking to raise their family and equally ideal for those looking to escape.

INVESTMENT PLAN: The perfect duplex floor plan is much more than just two homes attached to one. This design will provide excellent separation from your neighbors and offer plenty of space and privacy. On the rare occasion an entire duplex beach house for sale comes on the market, it is a great opportunity to bring in short- or long- term rental income by renting the other half and to control the entire structure. A duplex on the beach for sale is also ideal for family vacations. Duplexes offer the perfect amount of space for multiple families to holiday together while providing enough room for people to get some alone time when they need it most.
