ANOTHER PRICE IMPROVEMENT - REDUCED OVER $550,000! An exceptional opportunity to own TWO stunning residences in one purchase, located beach block to the powdery white sands of world-renowned Crescent Beach. Beach House Residences #301 AND the Penthouse together create a rare, turnkey coastal retreat where modern elegance and relaxed island living exist in harmony. Offered fully furnished and move-in ready, this one-of-a-kind, two-unit residence presents exceptional flexibility to embrace the ultimate Siesta Key lifestyle. Suited as a full-time or seasonal residence, a multi-generational family retreat, or a flexible ownership opportunity with the ability to enjoy or utilize one floor while renting another, short or long-term. Spanning the top two floors, this unique offering includes six generously sized bedrooms and five full baths (a four-bedroom, three-bath residence plus a two-bedroom, two-bath penthouse), thoughtfully designed to accommodate family and guests with ease. Expansive open floor plans welcome you with immediate Gulf views, while floor-to-ceiling glass and spacious balconies offer coastal breezes and blazing sunsets. Chef’s kitchens on each level are beautifully appointed to host unforgettable gatherings or intimate dinners, blending function with refined coastal style. Each residence enjoys its own private, secured entry, access to a state-of-the-art elevator, full kitchens, laundry rooms, luxury countertops, soft-close wood cabinetry, upscale lighting and designer fixtures. Additional highlights include spa-inspired baths, plush furnishings, 10-foot ceilings, spacious closets, a secure lobby, a private two-car garage and a hot tub on the penthouse-level balcony. Chic contemporary architecture enhances the building’s coastal presence, while sweeping Gulf and sunset views create a sense of escape. A private pet run oasis adds a thoughtful touch for four-legged companions. Outdoor living is equally inviting, and as a member of the community association, residents enjoy access to the pool and private beach entry, offering a seamless connection to the Gulf. Ideally within a half block of Siesta Key’s vibrant South Village, you are moments from beloved restaurants, cafés, tiki bars, boutiques, rentals and everyday conveniences. Complimentary trolley service provides easy access to Siesta Village, evoking the charm of a relaxed island-style experience, while quick access to the Stickney Point Bridge allows effortless travel on and off the island. With its prime beach-block location, thoughtful design and rare dual-residence configuration, this is a coastal offering that feels timeless and irreplaceable, an opportunity to create lasting memories on one of Florida’s celebrated shorelines.

Estimate the monthly payment

Estimate by Lasbury Tracy Realty — not a loan offer

Starting figures for 1140 SEASIDE DR #301 & Penthouse. Everything below is editable.

AssumptionNot a quoted rate. Ask a lender what you actually qualify for today.

From this listingThe seller's most recent annual tax bill as reported to the MLS. Your bill will differ — Florida reassesses on sale and homestead caps reset.

Editable estimateA placeholder, not a quote. On the Gulf Coast this is the line item most likely to be wrong: premiums swing on roof age, wind mitigation, elevation, and carrier appetite. Get a real quote before you rely on this number.

Starts at $0Deliberately zero until you enter a figure — we will not inflate a payment with a guess. Many homes here need it; ask us for the property's flood zone and the current policy's premium.

From this listingMonthly association fee as reported to the MLS. Confirm what it includes, and ask about special assessments.

AssumptionNot applied — your down payment is 20% or more.
