The community features coastal architecture ranging from charming cottages to oceanfront and estate homes, and its amenity package centers on a private oceanfront beach club with decks, two pools, and a summer kitchen, plus four private walkovers to St. Augustine Beach. That combination of a gate and direct beach access is unique on this stretch of coast.

Community Overview & History

The only gated oceanfront enclave on the beach

St. Augustine Beach is mostly open and low-key, which makes Sea Colony distinctive as the only gated oceanfront community on the beach. Built in a Key West coastal style with a private beach club and walkovers, it was designed as a secure, amenity-rich enclave for buyers who want the ocean with gated privacy, a rare offering on Anastasia Island.

How it feels on the ground today

Sea Colony reads as an upscale, private oceanfront enclave where the beach club, the pools, and the gated setting are the draw. It attracts affluent primary residents, second-home buyers, and those who want direct beach access with security. Because homes range from cottages to oceanfront estates, values span a wide range and the premium positions are limited.

The Community and What You Are Buying

Sea Colony spans cottages to oceanfront estates, so the choices come down to position relative to the beach and home size rather than separate sections.

Oceanfront and ocean-block homes

Homes on or near the Atlantic carry the highest premium for direct beach access and views.

Interior coastal homes

Interior homes and cottages within the gate offer a more attainable entry while still enjoying the beach club and walkovers.

Estate homes

Larger estate homes sit at the top of the community, combining the gate, the beach club, and generous coastal architecture.

Real Estate Market

Sea Colony appeals to affluent buyers who want gated oceanfront living, second-home buyers seeking a secure beach retreat, and those who value the private beach club and walkovers. The gate and the direct beach access are the headline draws.

Sea Colony has shown a median real estate price near 916,000 dollars, with active listings near 1,090,000 dollars according to third-party data in 2026. Because position relative to the beach drives so much of the value and inventory is limited, a specific home should be priced off the closest comparable sales for its type.

Buyers should review flood zone designation, windstorm and flood insurance, and the HOA dues and reserves closely, since the oceanfront setting means coastal considerations and amenity upkeep both factor into ownership.

Who Lives Here

Sea Colony draws affluent primary residents who want gated oceanfront living, second-home buyers seeking a secure beach retreat, and those who prioritize the private beach club, the pools, and the walkovers. The common thread is a desire for beach access with gated privacy on St. Augustine Beach.

Schools

Sea Colony is served by the St. Johns County School District, which is consistently ranked among the highest-rated public school districts in Florida. Elementary, middle, and high attendance zones are assigned by home address, so the dependable way to confirm where a particular Sea Colony address is zoned is the St. Johns County School District locator. If you are moving for a specific school, verify the assignment for the exact home before you write an offer, since boundaries can shift as the county adds capacity for its fast-growing population.

Amenities & Lifestyle

Sea Colony offers a private oceanfront amenity package behind a gate, a rare combination on St. Augustine Beach.

Private oceanfront beach club

A private beach club with decks and a summer kitchen is the social center of the community.

Two pools

Two community pools give residents resort-style water access within the gate.

Four beach walkovers

Four private walkovers provide direct, gated access to St. Augustine Beach.

Gated, park-like setting

Natural vegetation and sculpted landscaping give the enclave a private, park-like feel.

HOA, CDD & Costs

Sea Colony is governed by a homeowners association behind a gate, and the dues fund the gate, the beach club, the pools, the walkovers, and the common areas. Confirm the current dues and what they cover before buying.

Before closing, request the HOA budget and reserve information, since the oceanfront beach club, pools, and walkovers carry meaningful maintenance costs in a coastal setting.

Review the flood zone designation and obtain windstorm and flood insurance quotes early, and confirm any applicable CDD through the St. Johns County Property Appraiser.

Hidden Things Buyers Should Know

Coastal amenities need reserves

The oceanfront beach club, pools, and walkovers carry real maintenance costs, so read the HOA budget and reserve study before you buy.

Insurance is a real cost

Windstorm and flood insurance on a gated oceanfront home can be significant and belong in your monthly math alongside the dues.

Position drives the price

Oceanfront, ocean-block, and interior homes are different markets, so price off comparable sales for the exact position rather than a community average.
