  • Expansive private acreage: Occupying a rare one-acre site directly overlooking the Irish Sea, the property provides extraordinary outdoor space and exceptional privacy in a densely populated seaside suburb.
  • Meticulous period restoration: The residence has been thoroughly remodelled to a contemporary standard while successfully preserving the grand architectural proportions and fine features of its original Victorian villa heritage.
  • Generous bedroom count: Featuring six large double bedrooms, the layout easily accommodates a large family or visiting guests, ensuring everyone enjoys private quarters and luxury amenities.
  • Luxurious primary suite: The dedicated principal suite occupies the eastern side of the main floor, offering a sumptuous bedroom, separate sitting area, custom dressing room, and large ensuite bathroom.
  • Exceptional sea views: Sweeping granite steps and main reception rooms face directly towards the open water, delivering uninterrupted, picturesque marine vistas from the primary living spaces.
  • Custom Jonathan Williams kitchen: The front kitchen space is fitted with premium cabinetry and a massive Calacatta Gold marble island, combining aesthetic appeal with top-tier culinary functionality.
  • Discreet butler prep kitchen: Positioned behind hidden doors, the substantial secondary prep kitchen and wine store allows for seamless catering and keeps heavy kitchen operations out of view.
  • Dual terrace integration: Formal living and dining areas open onto distinct front and rear terraces, allowing occupants to track both morning sea views and late afternoon sunshine.
  • Versatile family cinema: The dedicated family living room features integrated blackout blinds and bespoke lighting, enabling the space to convert effortlessly into a private, cozy home cinema.
  • Dramatic cantilevered staircase: A bespoke open-riser staircase crafted from oak and frameless glass connects the garden level to the hall floor while drawing natural westerly light inward.
  • Dedicated home office: The garden level features a spacious home office with a feature bay window framing lovely views of the front lawn and the sea beyond.
  • Expansive entertainment room: A large family entertainment space at the garden level includes a pool table, retractable viewing screen, and custom cabinetry for relaxed indoor recreation.
  • Extensive guest ensuites: Multiple garden-level bedrooms benefit from private ensuite bathrooms, offering individual comfort and high-end privacy for family members or long-term guests.
  • Pre-approved pool permission: Full planning permission is already secured for a heated outdoor swimming pool with associated garden rooms on the seaward side of the property.
  • Approved garage development: The site includes valid planning permission for a bespoke, multi-car garage of considerable scale located along the front street boundary.
  • Commuter rail access: The local DART station at Sandycove and Glasthule is nearby, providing a swift twenty-minute journey directly into Dublin city centre.
  • Renowned local schools: Families will benefit from close proximity to several highly respected educational institutions including Loreto Abbey Dalkey, Rathdown, and Blackrock College.
  • Village proximity: The vibrant local villages of Sandycove, Glasthule, and Dalkey are within easy walking distance, offering excellent artisan shops, gourmet restaurants, and local services.
  • Smart home technology: Contemporary electrical installations, integrated AV systems, and automated features ensure the historic fabric of the home delivers modern living convenience.

But keep in mind:

  • Subpar energy rating: The recorded BER rating of D1 is poor for a luxury property at this price point, indicating potential thermal inefficiencies that will require substantial investment to rectify.
  • High energy upgrade costs: Achieving modern energy standards in a protected or historic Victorian structure can be exceptionally expensive and technically challenging due to conservation guidelines.
  • Significant heating demands: Heating a sprawling 640-square-meter period home with a D1 energy rating may result in very high ongoing utility bills during colder winter months.
  • Exorbitant asking price: At fourteen million euros, the asset demands a very specific tier of buyer, potentially limiting future liquidity and capital appreciation speed over the medium term.
  • Exposed coastal environment: Direct proximity to the Irish Sea exposes the exterior stonework, windows, and metal fixtures to harsh salt air, necessitating frequent and costly ongoing maintenance.
  • Unrealized planning liabilities: While planning permission exists for a swimming pool and garage, the buyer must absorb all construction costs and project management risks to build them.
  • Construction disruption risks: Executing approved major works like a seaward pool and multi-car garage will cause significant on-site disruption and noise after the initial purchase.
  • Historic preservation constraints: Local planning rules or conservation statuses may strictly limit any future internal or external modifications the buyer might wish to undertake.
  • Garden level moisture risks: Lower-ground or garden-level rooms in seaside period homes can be vulnerable to dampness and drainage issues, requiring diligent inspection of waterproofing measures.
  • Intense public footfall: Being located directly on a famous coastal amenity route near swimming spots can lead to high volumes of passing pedestrians and reduced street-level privacy.
  • Traffic and parking congestion: Sandycove Avenue East is a highly desirable and narrow coastal road, which can experience heavy visitor traffic and parking pressures during fine weather weekends.
  • Complex mechanical systems: The integration of hidden doors, specialized AV wiring, and custom motorized features may lead to complex and expensive maintenance calls over time.
  • Substantial insurance premiums: Insuring a high-value coastal property against storm damage, flooding, and high-value contents can command exceptionally steep annual policy costs.
  • High local property taxes: A luxury residence of this scale and location will attract maximum municipal property tax bands and associated transaction levies upon purchase.
  • Extensive window maintenance: Large period sash windows provide wonderful aesthetic character but can be drafty and expensive to properly draft-proof, repair, or thermally upgrade.
  • Potential boundary erosion: Buyers should commission a detailed coastal survey to assess any long-term erosion risks associated with owning a direct seafront land parcel.
  • Basement natural light limits: Despite clever staircase design, portions of the garden-level accommodation may receive less direct natural sunlight compared to the elevated hall floor.
  • Plumbing infrastructure age: Merging modern multi-bathroom facilities with older core property infrastructure requires thorough surveying to ensure adequate water pressure and pipe integrity.
  • Strict viewing protocols: The necessity for strict appointment-only viewings through specialized agents indicates a high level of vendor privacy control, which can occasionally protract due diligence inquiries.
  • High-end resale pool: The niche market for multi-million euro seaside historical villas means finding an equivalent buyer upon a future exit could take a prolonged marketing period.

Price positioning

?
This comparison depends on limited public and listing evidence, which may be incomplete, outdated or not directly comparable. The score is not a percentage, professional valuation or guaranteed estimate. Ask an independent qualified valuer before relying on a property value.
The asking price looks slightly overvalued compared with the available evidence.
  • The asking price of fourteen million euros appears somewhat ambitious when evaluated against verified transactions on the same road, where top-tier waterfront properties previously achieved substantial multimillion figures yet notably remained beneath this threshold.
  • Upward valuation signals stem from the substantial one-acre footprint, extensive floor area of approximately six hundred forty square meters, meticulous period restoration, and valuable granted planning permissions for a seaward swimming pool and bespoke multi-car garage.
  • Supporting factors include the premier coastal positioning directly overlooking the Irish Sea in an exclusive Dublin suburb, whereas potential downward pressure could stem from the D1 energy rating requiring prospective buyers to factor in modern efficiency upgrades.
  • Overall market positioning reflects a slight premium above local comparable benchmarks, capturing the exceptional rarity of a detached seaside Victorian villa combined with extensive contemporary fit-outs and comprehensive modern lifestyle amenities.

Build Analysis

What we know from similar construction types

  • The property is a large Victorian period villa of approximately 6,400 square metres, which has been recently and meticulously remodelled and restored.
  • A buyer should verify the structural integrity of the original fabric, especially given its coastal exposure to the Irish Sea.
  • Planning permission is noted as secured for a seaward swimming pool and a bespoke front car garage, and a buyer should inspect these permissions and conditions carefully via their legal representative.
  • Given the substantial floor area and period nature, a thorough investigation into modern services, insulation upgrades, and compliance with current building regulations during the remodelling works is recommended.

Retrofit Cost*

Possible renovating / insulating expenditure

  • The BER rating is D1, which falls into the D to G category requiring a deep-retrofit cost estimate.
  • For a very large period property of approximately 640 square metres, a comprehensive deep retrofit to bring it to a high BER rating (such as A or B) would likely require significant capital expenditure.
  • Estimated costs could range from €150,000 to €250,000 or more, depending on the extent of works needed for external insulation (balanced against preserving the Victorian facade), upgrading heating systems, windows, and renewable technologies.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: €5,000 to €7,000 per year.
  • Explanation: Given the large 640 m² floor area and a D1 BER rating indicating poorer energy efficiency compared to modern builds, heating this expansive Victorian residence will require significant energy consumption.

Pollution Safe

9/10

Environmental situation to investigate

  • The property is located in an established coastal residential area with no apparent large-scale industrial facilities, heavy manufacturing, or active landfills in immediate proximity.
  • Any historical urban or coastal pollutant concerns should be independently investigated by the prospective buyer as part of standard due diligence.

Flood Safe

7/10

Water overflow reports to follow up

  • The residence occupies an elevated position directly overlooking the Irish Sea, which generally mitigates low-level surface water accumulation but introduces coastal exposure considerations.
  • Prospective buyers are advised to verify comprehensive local coastal flood risk assessments and insurance availability given the direct waterfront setting.
