RARE 4-LOT WATERFRONT ESTATE OPPORTUNITY ON DAUPHIN ISLAND

Zillow's Estimate is for the one lot with the house. This listing includes 4 lots combined.

420 Brava Costa Street | Dauphin Island, Alabama

A truly unique opportunity on Dauphin Island’s desirable East End.

This waterfront property consists of four contiguous buildable lots with approximately 350 feet of waterfront, all being offered together as one complete property.

The existing 5-bedroom, 3-bath home sits across the center portion of the property and can be renovated and enjoyed as-is, or the property offers the rare opportunity to start fresh and build a substantial custom waterfront estate across all four lots.

Situated on a protected cove with deep-water access suitable for larger boats, the property combines privacy, boating access and an amount of waterfront that is extremely difficult to duplicate on the East End.

A covered boathouse has also recently been approved, adding even more value for a serious boating buyer.

Property Highlights

• Four contiguous buildable waterfront lots • Approximately 350 feet of waterfront • Point-style waterfront setting with expansive views • Protected cove • Deep water suitable for larger boats • Recently approved covered boathouse • Existing 5-bedroom, 3-bath residence • Renovate the current home or build a completely new custom estate • Exceptional room for a pool, outdoor living, garages, guest space and landscaping • No HOA • Property will not be subdivided • Offered only as one complete waterfront estate

Individual waterfront homes and lots become available from time to time.

What is nearly impossible to recreate is four adjoining buildable waterfront lots with approximately 350 feet of frontage in one of the most desirable areas of Dauphin Island.

For the buyer who has been waiting for enough land and waterfront to build something truly exceptional, this is that opportunity.

Offered at $3,500,000

Serious inquiries only.
