What you'll like:

  • Spectacular coastal views: The property enjoys breathtaking, elevated views across Dublin Bay and Brighton Vale, creating a picturesque and highly desirable living backdrop for future residents.
  • Substantial site scale: Occupying approximately 0.2 acres, the sizable plot offers rare breathing room and extensive outdoor space within a densely populated coastal neighborhood.
  • Massive road frontage: An impressive 70 metres of road frontage provides incredible presence, prominent visual appeal, and exceptional configuration flexibility for the existing plot.
  • Dual vehicular access: Two separate gated entrances onto Seapoint Avenue enhance day-to-day convenience, traffic management, and potential future site division configurations.
  • Flexible dual layout: Currently arranged as two independent self-contained residences, it accommodates multi-generational living arrangements, guest quarters, or distinct rental income streams seamlessly.
  • Generous floor area: Spanning approximately 220 square metres, the total accommodation delivers well-proportioned rooms with high spatial versatility across both individual levels.
  • Prime coastal address: Situated in one of South County Dublin's most prestigious locations, the home places residents moments away from famous swimming spots and marine amenities.
  • Strolling village proximity: Both Monkstown and Blackrock villages are within an easy walking distance, offering celebrated restaurants, boutique shops, and vibrant weekend markets.
  • Exceptional transit connectivity: Seapoint DART Station sits just minutes away on foot, ensuring rapid, reliable commuter access directly into Dublin city centre.
  • Plentiful off-street parking: Gated driveways provide secure parking options for multiple vehicles, addressing a major premium convenience for properties in this coastal district.
  • Development upside: The expansive site and configuration present an outstanding canvas for comprehensive refurbishment, dramatic extensions, or complete redevelopment subject to planning.
  • Attic expansion potential: A large floored and insulated attic space equipped with a pull-down Stira ladder provides immediate storage and future conversion headroom.
  • Outdoor garden spaces: Features mature boundaries, private lawn areas, and sunny patio zones designed to maximize enjoyment of the tranquil coastal environment.
  • Proximity to elite education: Some of Dublin's finest primary schools, secondary institutions, and major universities like UCD and Trinity College are easily accessible.
  • Included fixtures: The sale incorporates fitted carpets, curtains, and essential kitchen appliances across the units, easing the initial transition for new owners.
  • Natural light optimization: Upper reception rooms feature clever dual-aspect alignments and corner windows that flood the core living spaces with bright daylight.
  • Outdoor entertainment terrace: A generous upper-floor viewing terrace provides a magnificent platform for outdoor relaxation while framing expansive bay panoramas.
  • Established neighborhood character: Surrounded by Victorian streetscapes and high-value properties, the area guarantees strong long-term desirability and neighborhood prestige.
  • Recreational lifestyle access: Local yacht clubs, sailing facilities, and scenic waterfront promenades support an active, outdoor-focused coastal lifestyle right outside the door.
  • Solid structural scale: The detached footprint provides excellent privacy between neighbors, avoiding party wall complications typical of terraced coastal alternatives.

But keep in mind:

  • Poor energy rating: The property carries a weak BER rating of F with a high energy consumption index, indicating severe thermal inefficiency requiring upgrades.
  • Extensive upgrade required: Significant capital expenditure will be needed immediately to modernize outdated interior finishes, heating infrastructure, and layout flow.
  • Planning permission risks: Any major reconfiguration, extension, or total redevelopment plans remain entirely subject to stringent local planning authority approvals.
  • High baseline acquisition cost: Priced at €1,500,000 before factoring in substantial renovation or retrofitting budgets to bring it up to modern standards.
  • Potential damp and exposure: Being directly on a coastal avenue exposes the structure to heavy maritime weather, increasing ongoing maintenance and corrosion risks.
  • Outdated heating systems: Independent gas boilers servicing separate units may require total replacement to achieve contemporary safety and efficiency benchmarks.
  • Complex asset management: Owning a multi-unit layout or managing a large footprint requires careful structural oversight and potential legal consolidation if returning to a single home.
  • Renovation logistical hurdles: Working on a prominent coastal road could introduce traffic management and material staging challenges during extensive construction phases.
  • Insulation deficiencies: Despite attic insulation, external walls and older windows likely suffer from major heat loss typical of un-upgraded period properties.
  • Restricted sunroom footprint: The ground-floor sunroom and lean-to utility spaces are of lighter construction and may require rebuilding or proper thermal integration.
  • Traffic and noise exposure: Positioned directly on Seapoint Avenue, the plot may experience higher ambient traffic volumes during peak commuting and leisure hours.
  • Uncertain compliance history: Buyers should verify whether historical extensions, internal divisions, or outbuildings possess full local authority planning compliance.
  • Upgrading costs for BER: Moving the building's energy rating from an F to a sustainable modern standard will demand substantial insulation and window investments.
  • Potential boundary clarity: Due to the vast 70-metre frontage, buyers should verify exact legal boundaries and fence lines against historical folio maps.
  • Dated bathroom amenities: Multiple bathrooms feature older sanitary ware and tiling configurations that warrant immediate stripping and modern refitting.
  • Kitchen appliance wear: Included kitchen appliances across both levels appear older and should be budgeted for replacement during property renovations.
  • Roof and gutter maintenance: High exposure to coastal winds means the roof tiles, flashing, and rainwater goods require thorough professional engineering inspection.
  • Surface water drainage: Buyers must investigate site drainage capacity on the 0.2-acre plot to ensure heavy coastal downpours drain away safely from foundations.
  • Asbestos due diligence: Given the age of construction elements, buyers should check for legacy hazardous materials like asbestos in textured coatings or pipe lags.
  • Future utility capacity: Upgrading the property into a single luxury residence or expanding multi-family use may necessitate electrical service capacity upgrades.

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 appears broadly in line, with a slight undervaluation signal.
  • The asking price of one million five hundred thousand euros is aligned with comparable high-end coastal properties offered via auction campaigns in premier South County Dublin locations.
  • Comprehensive refurbishment is required given the poor energy rating, meaning prospective purchasers should carefully evaluate modernization costs alongside the initial capital outlay.
  • The substantial zero point two acre site layout with dual vehicular access and extensive road frontage provides unique development versatility that supports the baseline valuation level.
  • Uninterrupted views across Dublin Bay and immediate proximity to transport links heavily influence the pricing structure relative to standard residential housing stock nearby.

Build Analysis

What we know from similar construction types

  • The property is currently arranged as two self-contained residences across two levels, offering extensive flexibility for multi-generational living or redevelopment, subject to planning permission.
  • The building features a poor BER rating of F, indicating a high level of energy inefficiency that will require comprehensive thermal upgrades.
  • A buyer should investigate the structural integrity, dampness levels, and overall condition of the existing fabric, particularly given the coastal environment of Seapoint Avenue which can accelerate weathering.
  • The expansive site of approximately 0.2 acres with 70 metres of road frontage and dual vehicular entrances presents major development or extension potential, which should be verified via local planning guidelines.
  • The large floored and insulated attic offers potential for conversion, though any structural changes or habitable use should be checked for compliance and planning requirements.

Retrofit Cost*

Possible renovating / insulating expenditure

  • The property has a poor BER rating of F and a floor area of approximately 220 m², meaning a whole-house deep retrofit is necessary to bring it to a modern energy-efficient standard (such as a BER rating of B2 or higher).
  • A deep retrofit for a 220 m² detached or multi-unit structure typically involves external or internal wall insulation, upgrading windows and external doors to high-performance double or triple glazing, roof insulation enhancement, installing a modern heat pump system or high-efficiency boiler, and air tightness improvements.
  • Estimated total costs for a comprehensive deep retrofit of this scale in Ireland generally range from €80,000 to €130,000+, depending on the extent of structural alterations required, contractor pricing, and potential SEAI grants available.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: €3,500 to €5,000. Explanation: The property has a poor BER rating of F and a large floor area of approximately 220 m² divided across two self-contained residences with gas-fired central heating, meaning energy efficiency is low and thermal loss is likely high, though actual costs will depend heavily on usage habits and potential upgrades.

Pollution Safe

8/10

Environmental situation to investigate

  • The area is primarily residential and coastal, appearing largely free from heavy industrial pollution concerns.
  • Any historical local commercial activities or legacy concerns should be independently verified by the buyer.

Flood Safe

7/10

Water overflow reports to follow up

  • The property occupies an elevated coastal position overlooking Dublin Bay, which provides a natural buffer against many typical rising tide issues.
  • Given its direct proximity to the seafront at Seapoint, buyers should review official coastal flood risk mapping and insurance reports.
