Marco Island • 140 Seaview Court • Beachfront Condominiums
Admiralty House Marco Island Condos for Sale
Admiralty House is an established beachfront condominium at 140 Seaview Court on Marco Island. The high-rise contains approximately 200 residences arranged in mirrored north and south sections, with one- and two-bedroom floor plans, private balconies, covered parking, storage and direct access to Marco Island's Gulf beach.
Current MLS and Collier County-derived property records generally identify 1973 construction, while some older building marketing references use 1974. The condominium is an approximately 18-story high-rise and remains one of the larger established beachfront communities along Seaview Court.
Admiralty House is especially interesting from a real-estate comparison standpoint because its five principal floor-plan categories create very different view profiles. Some residences look directly west toward the Gulf and sunsets, some combine Gulf and island views from corner or dual balconies, and the compact 04-stack one-bedroom residences primarily emphasize eastern Marco Island views.

Admiralty House at 140 Seaview Court
Admiralty House occupies a Gulf-front site on the northern half of Marco Island's principal beach corridor.
The building sits between Seaview Court and the beach, allowing owners and guests to reach the sand directly from the condominium grounds rather than crossing a major roadway.
Its location provides convenient access to North Collier Boulevard, restaurants, shopping and other Marco Island destinations while preserving direct beachfront living.
Nearby beachfront condominiums include Tradewinds, Sunset House, Sunset House North and the South Seas Club complex, making this part of the island a particularly useful area for building-to- building comparison.
200-Residence Admiralty House High-Rise
Admiralty House contains approximately 200 individually owned condominiums within a single beachfront high-rise.
The building is divided symmetrically into North and South sections. Matching unit stacks appear on each side, so a residence number alone should always be considered together with its North or South designation.
The repeating floor-plan structure creates a useful framework for comparable-sales analysis because buyers can often begin with the same stack before adjusting for floor height, renovation and hurricane protection.
Admiralty House Floor Plans
Admiralty House has five principal floor-plan types mirrored between the North and South portions of the building.
Published plans range from approximately 604 square feet for the one-bedroom 04 residences to approximately 896 square feet for the largest two-bedroom layouts.
Current MLS reporting can differ slightly from the original published measurements. For example, the 04 floor plan is published around 604 square feet while current property records commonly report approximately 610 square feet.
01 Units Two bedrooms and two baths with the building's distinctive dual-balcony arrangement, combining beachfront and secondary island exposure.
02 & 03 Units Two-bedroom, two-bath Gulf-facing plans designed around long beach views. Current records commonly report approximately 837–844 square feet.
04 Units One bedroom and one-and-one-half baths with primary island-facing views. Original published area is approximately 604 square feet; current MLS frequently reports about 610.
05 Units Two bedrooms and two baths with a corner balcony and strong beachfront exposure. Current examples are reported around 896 square feet.
06 Units Two bedrooms and two baths in a corner configuration emphasizing sunrise and side-beach views. Current examples are reported around 868 square feet.
North & South Versions Each principal stack appears in mirrored North and South locations, making orientation part of the comparable-sales analysis.
Admiralty House 01 Condos
The 01 residence is one of Admiralty House's more distinctive two-bedroom floor plans because it incorporates two private balcony exposures.
The building's published floor-plan guide describes these residences as offering the best combination of both view directions.
Current and recent sales of 01-stack residences have been reported around the upper-800-square-foot range, although buyers should verify the exact legal and MLS living area of the individual unit.
The dual exposure can create both sunrise and sunset experiences within the same condominium, an important distinction from single-balcony interior stacks.
Admiralty House 02 & 03 Condos
The 02 and 03 stacks are two-bedroom, two-bath beachfront residences designed around long western Gulf and beach views.
Current MLS and recent sales commonly report interior living area around 837 to 844 square feet.
These residences can appeal particularly to buyers who prioritize a direct connection with the Gulf and sunset views over the additional island exposure found in some corner configurations.
Admiralty House One-Bedroom 04 Condos
The 04 floor plan is Admiralty House's principal one-bedroom, one-and-one-half-bath residence.
The original published floor-plan information identifies approximately 604 square feet, while current MLS and county-derived records frequently report approximately 610 square feet.
Unlike the principal beachfront two-bedroom stacks, the 04 residences emphasize eastern or inland Marco Island views.
That difference creates a separate valuation category within Admiralty House. A one-bedroom 04 residence should not be priced primarily against a Gulf-facing two-bedroom condominium simply because both share the same building.
Admiralty House 05 Corner Condos
The 05 floor plan provides two bedrooms and two bathrooms in a corner-balcony configuration.
Current property records document examples around 896 square feet, placing the 05 stack among the largest conventional Admiralty House residences.
Its corner position can broaden the beachfront outlook and increase natural light compared with interior Gulf-facing layouts.
Admiralty House 06 Corner Condos
The 06 stack provides two bedrooms and two bathrooms with a different corner orientation from the 05 residences.
The building's floor-plan guide emphasizes sunrise and side-beach views for this position. Current MLS examples are reported around 868 square feet.
For buyers comparing a 05 and 06 residence, interior size is only one consideration. Direction, balcony exposure, Gulf visibility and sunrise-versus-sunset emphasis can materially change the experience.
Direct Marco Island Beach Access
Admiralty House is a true beachfront condominium.
Owners and guests can move directly from the building grounds to Marco Island's white-sand beach, supporting swimming, shelling, beach walking and sunset viewing without driving to a public access point.
Direct Gulf frontage is a permanent characteristic of the real estate and should be separated from interior finishes when evaluating value.
Gulf, Beach, Sunset & Island Views
The five Admiralty House floor plans create several fundamentally different view categories.
The 02 and 03 residences emphasize long western beach and Gulf views. The 05 and 06 corner stacks combine shoreline views with different secondary exposures, while 01 residences benefit from their dual-balcony design.
The one-bedroom 04 homes primarily look toward Marco Island rather than directly west over the Gulf.
Admiralty House view analysis: identify the exact unit stack and North or South designation before assigning a value premium for floor height. A higher floor does not make fundamentally different view orientations directly comparable.
Private Balconies & Outdoor Living
Every Admiralty House floor plan incorporates private outdoor living.
Balcony type varies significantly by residence: beachfront balconies, corner balconies and the 01 stack's dual-balcony arrangement each produce different usable outdoor space and views.
Buyers should compare balcony dimensions, orientation, railing condition, sliding doors, hurricane protection, waterproofing and association responsibility for exterior components.
Floor Height at Admiralty House
Admiralty House rises approximately 18 stories, so elevation can create substantial differences within the same floor-plan stack.
Higher residences generally expand the horizon and reduce the visual effect of nearby landscaping or structures. Lower floors maintain a closer relationship with the beach, pool and surrounding grounds.
The building also includes upper-floor and penthouse-designated residences. Their scarcity can affect value even when interior living area resembles a conventional floor below.
Beachside Swimming Pool
Admiralty House provides a large community swimming pool within its beachfront grounds.
The pool gives owners and guests a maintained swimming option within steps of Marco Island's Gulf beach.
The surrounding outdoor recreation environment also includes barbecue facilities for casual gatherings and dining.
Two Tennis Courts
The Admiralty House association identifies two tennis courts as part of the condominium amenities.
Current scheduling, guest use and reservation procedures should be confirmed through association management.
Social Room & Community Kitchen
Admiralty House includes a spacious social room with kitchen facilities.
The room provides indoor gathering space for owners, guests and association activities and complements the pool, beach and outdoor recreation areas.
Covered Assigned Parking
Admiralty House floor-plan information identifies one covered parking space with each residence.
Current MLS records commonly describe these spaces as detached carports or assigned covered parking.
The exact space associated with the condominium should still be verified before closing.
Parking due diligence: confirm the assigned space number, location, coverage, vehicle restrictions, guest parking and transfer rights through current association and title information.
Private & Climate-Controlled Storage
Storage is a notable Admiralty House feature.
Published building information identifies exterior storage associated with the covered parking area together with additional air-conditioned storage serving the residential floors.
The exact storage assignment and transfer rights should be confirmed for each individual condominium.
Laundry Rooms on Each Floor
Admiralty House provides shared laundry rooms on each residential floor.
That arrangement is especially relevant to the compact one-bedroom homes because it allows the private floor plan to remain dedicated to living space rather than requiring a washer and dryer inside every residence.
Buyers should verify whether any individual remodeled residence has a different approved laundry arrangement.
Car-Wash Area
The condominium association includes a dedicated vehicle-wash area among the Admiralty House amenities.
This can be useful in a beachfront environment where salt, sand and coastal exposure make routine vehicle cleaning particularly practical.
Impact Windows, Doors & Hurricane Protection
Hurricane protection varies by individual Admiralty House residence.
Current 2026 listings include examples with impact-resistant windows and sliding doors, while some residences also retain supplemental shutters.
Buyers should verify every exterior opening individually rather than assume that impact protection is uniform throughout the building.
Responsibility for windows, balcony doors, shutters and related components should also be reviewed in the current condominium documents.
Renovated vs. More Original Admiralty House Condos
Admiralty House dates to the early 1970s, so the private residences now represent many different renovation generations.
Updated homes may include redesigned kitchens, renovated bathrooms, impact glazing, new flooring, custom cabinetry, replacement lighting and newer mechanical equipment.
Other condominiums may remain closer to their earlier configuration and provide an opportunity to renovate around a desirable floor plan, elevation and view.
Kitchen Review cabinetry, counters, appliances, plumbing, electrical updates and any material changes to the original floor plan.
Bathrooms Evaluate plumbing, waterproofing, fixtures and renovation quality.
Impact Protection Verify each window, sliding door and exterior opening.
HVAC Confirm equipment age, service history and anticipated replacement needs.
Flooring Review material, condition and applicable association sound-control requirements.
Permits & Approval Material alterations should be checked for applicable permits and required association approval.
Admiralty House Rental Rules
Admiralty House is a monthly rather than weekly-rental beachfront condominium.
Current published building guidance describes the rental policy as one rental per 30-day period, establishing a minimum monthly rental structure.
This creates a different ownership profile from weekly-rental Marco Island beachfront buildings such as Apollo and Sea Winds.
Buyers planning to rent should confirm the current lease application, approval process, registration requirements, permitted annual frequency and any subsequent amendments directly through association management.
Current published Admiralty House rental guidance: one rental per 30-day period. Verify the complete current leasing rules before relying on rental income.
Admiralty House Pet Policy
Current building-specific guidance identifies Admiralty House as a no-pet condominium for ordinary household pets.
Current MLS listings likewise report pets as not allowed.
Legally protected assistance-animal accommodations are governed separately from ordinary pet restrictions and should be handled under applicable law and current association procedures.
Admiralty House, Inc.
The legal condominium association is Admiralty House, Inc., an active Florida not-for-profit corporation with its principal property at 140 Seaview Court.
The corporation was originally filed in 1972, reflecting the building's early place in Marco Island's beachfront condominium development.
Buying in an established high-rise requires evaluation of both the private condominium and the financial, structural and insurance condition of the association.
Operating Budget Review recurring management, utilities, maintenance, landscaping and recreation expenses.
Reserve Funding Compare available reserves with anticipated repair and replacement obligations.
Master Insurance Review property and wind coverage together with deductibles, exclusions and owner responsibilities.
Special Assessments Identify approved, pending, recently completed and reasonably anticipated assessments.
Structural Documentation Review applicable milestone-inspection, engineering and Structural Integrity Reserve Study documentation.
Capital Projects Review exterior walls, balconies, roof, elevators, pool, electrical, plumbing, fire-safety and waterproofing projects.
Structural & Reserve Due Diligence
The age and beachfront exposure of Admiralty House make current structural and reserve documentation important buyer-review items.
Buyers should obtain the applicable milestone-inspection information, Structural Integrity Reserve Study, recent engineering reports, current reserve schedule, meeting minutes and information regarding any major completed or planned projects.
A well-renovated private residence does not eliminate the need to understand the condition and funding of the overall condominium building.
Flood, Wind & Condo Insurance
Admiralty House's direct coastal setting makes insurance review an essential part of purchase due diligence.
Buyers should understand how the association's master insurance interacts with individual HO-6 coverage, including wind deductibles, loss-assessment protection and responsibility for interior improvements.
Current flood information, lender requirements and owner responsibility for windows, doors and other exterior components should be reviewed for the specific transaction.
What Admiralty House Buyers Should Compare
North or South Identify the correct mirrored side of the building before selecting comparable sales.
01–06 Stack Floor-plan position determines bedroom count, interior size, balcony design and principal view.
Bedroom Count Separate the one-bedroom 04 residences from every two-bedroom comparison.
Living Area Current published sizes range from approximately 604/610 to 896 square feet.
Floor Height Elevation changes Gulf horizon, island view, privacy and beach perspective.
Gulf Exposure Distinguish direct beachfront, corner, side-beach and island-view configurations.
Balcony Type Compare conventional, corner and dual-balcony arrangements.
Parking Verify the exact covered parking space associated with the residence.
Storage Confirm all private, exterior and floor-level storage rights.
Impact Protection Verify every exterior opening independently.
Renovation Separate cosmetic finishes from plumbing, electrical, mechanical and permitted improvements.
Association Financials Review budget, reserves, insurance, assessments and capital planning.
Structural Reports Review applicable engineering, milestone and reserve-study documentation.
Rental & Pet Rules Confirm current monthly rental provisions and no-pet policy before closing.
How to Value an Admiralty House Condo
Admiralty House valuation should begin with the exact floor-plan stack rather than a broad building-wide price-per-square-foot average.
A 610-square-foot one-bedroom 04 residence belongs in a very different comparable-sales group from an 837-square-foot direct beachfront two-bedroom or an approximately 896-square-foot corner residence.
Once the correct floor-plan group is identified, North or South location, elevation, Gulf visibility, balcony configuration, parking, impact protection and renovation can refine the comparison.
Admiralty House valuation sequence: bedroom count → 01–06 stack → North or South → living area → floor height → Gulf or island view → balcony → parking & storage → impact protection → renovation → association condition.
Admiralty House 2026 Market Context
Recent 2026 market activity demonstrates the range of Admiralty House residence types.
One-bedroom 04-stack transactions have been reported around 610 square feet, while two-bedroom market activity includes residences around 837, 868 and 896 square feet.
A 610-square-foot one-bedroom residence closed in April 2026, another closed in July 2026, and an approximately 896-square-foot two-bedroom residence closed in May 2026.
Current inventory has also included 837- and 868-square-foot two-bedroom residences, reinforcing the importance of floor-plan-specific comparison.

Admiralty House vs. Other Marco Island Beachfront Condos
Admiralty House differs significantly from many of the beachfront buildings already represented in this directory.
Its residences are smaller than the large luxury floor plans found at Sandpiper, Les Falls, Summit House or Madeira, while its 30-day rental structure is less flexible than weekly-rental Apollo, Sea Winds and Somerset.
Admiralty House instead appeals to buyers seeking an established beachfront building with comparatively efficient one- and two-bedroom floor plans, multiple view orientations, private balconies, covered parking and substantial beachfront grounds.
For buyers comparing the northern beachfront corridor, nearby Tradewinds, Sunset House, Sunset House North and South Seas Club can provide particularly relevant alternatives.
Selling an Admiralty House Condo
Admiralty House sellers should begin with the exact floor-plan stack and North or South building position.
For example, a one-bedroom 04 residence should be compared first with other 04 sales rather than against the direct-Gulf two-bedroom market.
For two-bedroom homes, 01 through 06 position, floor height, Gulf visibility, balcony design, living area, impact protection and renovation can each influence value.
Recent same-building transactions should generally receive more weight than unrelated Marco Island beachfront sales when adequate comparable data exists.
