What you'll like:
- Spectacular coastal views: The elevated position delivers breathtaking, uninterrupted vistas across Dublin Bay, providing a permanent visual asset that significantly enhances daily living and long-term asset value.
- Prime coastal location: Situated in a highly prestigious neighbourhood, residents enjoy immediate proximity to Seapoint promenade, local yacht clubs, and the vibrant amenities of Monkstown and Blackrock villages.
- Exceptional public transport: The property is located just minutes away from Seapoint DART Station, ensuring rapid, reliable commuter access directly into Dublin city centre and surrounding coastal suburbs.
- Generous site dimensions: Occupying approximately 0.2 acres, the substantial plot size provides a rare footprint for a coastal property, offering expansive outdoor space and incredible flexibility for future enhancements.
- Extensive road frontage: Boasting an impressive 70 metres of road frontage along Seapoint Avenue, the property commands a prominent profile and secures rare spatial independence within the immediate streetscape.
- Dual vehicular entrances: The inclusion of two separate gated vehicular access points onto Seapoint Avenue maximizes overall site functionality, parking convenience, and future layout configurations for any potential redesign.
- Ample off-street parking: The gated driveway configuration easily accommodates multiple vehicles securely off the main road, addressing a major premium requirement for multi-car households in this dense coastal area.
- Substantial floor area: Providing approximately 220 square metres of internal accommodation, the dual-level layout delivers generous proportions that can comfortably support a wide range of modern family lifestyle needs.
- Flexible dual-residence layout: Currently arranged as two distinct self-contained units, the property offers fantastic versatility for multi-generational living arrangements, guest quarters, or immediate supplemental rental income generation.
- Significant redevelopment scope: The scale of the site and its prominent frontage present an outstanding canvas for comprehensive refurbishment, radical extension, or complete redevelopment subject to planning permission.
- Attic conversion potential: The large floored and insulated attic space features generous headroom and pull-down stair access, representing an easily tapped reservoir of extra storage or future habitable rooms.
- Established outdoor living: The gardens feature mature planting, lawn areas, and a paved patio that create private, sheltered zones for outdoor relaxation and entertaining just steps from the shoreline.
- Dual-aspect living spaces: The upper principal living room benefits from corner windows and dual aspects, flooding the interior with natural light while framing magnificent coastal and urban backdrops.
- Included appliances and fittings: The sale includes fitted carpets, curtains, and essential kitchen appliances across both units, offering immediate utility for occupants or tenants during initial transitional phases.
- Established local amenities: Proximity to celebrated weekend markets, artisan food shops, boutique shopping, and highly regarded dining establishments ensures an exceptionally convenient and vibrant lifestyle for future occupants.
- Proximity to elite education: The address is surrounded by some of Dublin's finest primary and secondary schools, alongside convenient transport links to major universities including UCD and Trinity College.
- Stable asking-price positioning: Recorded listing snapshots indicate a firm, unchanged asking price of €1,500,000, providing price stability and a clear baseline for serious prospective buyers entering negotiations.
- Outdoor recreation access: Morning swims, coastal walks, and sailing clubs right on the doorstep offer an active, enviable outdoor lifestyle that is exceptionally difficult to replicate elsewhere in the capital.
- Strong architectural character: The landmark detached nature of the building imbues it with a distinct local presence and traditional charm that can be brilliantly preserved during modern modernization works.
- Independent utility provisions: Separate living arrangements across two levels mean services and heating systems are largely decentralized, facilitating phased renovations without entirely disrupting living quarters.
But keep in mind:
- Poor energy efficiency: The property currently records a very low BER rating of F with a high energy performance indicator, indicating significant insulation deficiencies and draft vulnerabilities requiring costly upgrades.
- Substantial capital expenditure required: Achieving modern comfort standards and addressing the F-rated energy profile will necessitate heavy investment in deep retrofitting, heating modernization, and window replacements.
- Planning permission uncertainties: Any major redevelopment, structural extension, or conversion of the existing footprint remains entirely subject to local authority planning consent, introducing regulatory risk for ambitious buyers.
- Dated interior finishes: Much of the internal decor, kitchens, and bathrooms show traditional styling and wear, meaning a comprehensive interior overhaul is virtually mandatory for modern tastes.
- High energy operational costs: The poor thermal performance highlighted by the BER rating will likely translate into high monthly heating and electricity bills until extensive energy efficiency works are completed.
- Maintenance of mature grounds: The extensive gardens and mature planting will require ongoing horticultural upkeep and tree management to prevent overgrowth and maintain structural boundary integrity.
- Traffic and parking management: Being located on a busy coastal thoroughfare like Seapoint Avenue may introduce traffic noise and require careful maneuvering when utilizing the vehicular entrances during peak hours.
- Stagnant pricing strategy clues: The unchanged asking price over the observed monitoring period suggests firm vendor expectations, potentially signaling limited initial flexibility in early negotiation rounds.
- Complex reconfiguration challenges: Merging or updating the currently separated upper and lower dwellings into a single unified family home will require significant architectural intervention and associated structural costs.
- Moisture and damp management: Proximity to the marine environment means coastal weather exposure can accelerate exterior wear, requiring vigilant inspection of masonry, roof tiles, and window seals.
- Outdated heating systems: The presence of older boiler units within the kitchen spaces indicates that heating infrastructure should be thoroughly inspected and likely replaced with modern high-efficiency alternatives.
- Lean-to utility structure: The utility room is described as a lean-to construction, which often points to lighter building standards, potential thermal bridging, and the need for future structural reinforcement.
- Limited ground-floor sightlines: Certain ground-floor rooms rely on sunrooms and rear orientations, which may result in lower natural light levels compared to the panoramic upper-floor living spaces.
- Auction sale mechanics: The property has been marketed for sale by public auction, which typically demands unconditional financial preparedness, immediate deposit availability, and strict closing timelines for bidders.
- Hidden structural defect risks: Given the age and landmark status of the detached structure, buyers should budget for potential concealed issues such as outdated electrical wiring, plumbing corrosion, or roof timber fatigue.
- Compliance of previous alterations: Buyers must verify that all historical internal divisions, additions, or structural modifications comply fully with local planning history and building control regulations.
- Boundary clarity verification: Given the extensive 70-metre road frontage and historical layout, legal due diligence is essential to confirm exact boundary lines, rights of way, and service easements.
- Acoustic insulation between units: As the building is arranged in two self-contained levels, sound transmission between the upper and lower residences may be noticeable without dedicated acoustic dampening upgrades.
- Strict modernization timelines: Undertaking extensive renovations on a large coastal property will require careful project management and temporary alternative accommodation if living on-site during construction.
- Resale value sensitivity: Because the property commands a high baseline price of €1,500,000 before renovation costs, buyers must carefully evaluate local ceiling prices to ensure future refurbishment investments align with market realities.
Price positioning
?
- The asking price appears somewhat undervalued given the exceptional coastal positioning and large site size, though this is heavily counterbalanced by the poor energy rating and the substantial capital required for comprehensive modernization or future development.
- Signals supporting potential under-valuation include extensive road frontage, dual vehicular access points, and rare panoramic views over Dublin Bay, while valuation risks are driven by the obsolete F energy rating and outdated interior configuration.
- Supporting the current quoting strategy are the premier seaside location near Monkstown and Blackrock alongside high development flexibility, whereas factors that could undermine this price point include planning permission uncertainties and high renovation costs.
- Relevant contextual elements involve the property currently being arranged as two self-contained dwellings, which provides immediate multi-generational living or rental income potential while buyers navigate long-term architectural transformation plans.
Build Analysis
What we know from similar construction types
- The property is currently arranged as two self-contained residences across approximately 220 sqm, offering potential for full restoration into a single family home, continued use as separate dwellings, or future redevelopment subject to planning permission.
- Features a substantial 0.2-acre site with 70 metres of road frontage and two separate vehicular entrances onto Seapoint Avenue, providing significant flexibility for parking or future works.
- Buyers should investigate the structural integrity, damp proofing, and the condition of the roof, windows, and two separate gas-fired central heating boiler systems.
- Planning and compliance status regarding the division into two units and any potential future extensions or redevelopment proposals should be verified with local planning authorities.
Retrofit Cost*
Possible renovating / insulating expenditure
- Given the F BER rating and an area of approximately 220 square metres, a comprehensive deep retrofit is required to bring the property to modern energy efficiency standards.
- Estimated costs range from €70,000 to €110,000, which would typically cover external wall insulation or internal drylining, upgraded roof insulation, window and door replacements, and the installation of a modern heat pump or high-efficiency heating system, alongside airtightness and ventilation improvements.
Heating cost*
Estimated expense to heat this property every year
- Estimated annual heating cost: €3,500 to €5,000.
- Explanation: Given the property has a poor BER rating of F, an energy performance indicator of 387.89 kWh/m/yr, a large floor area of approximately 220 m², and is currently arranged as two separate residences with gas-fired central heating, energy inefficiency will lead to significantly higher than average annual heating expenses until comprehensive thermal upgrades are carried out.
Pollution Safe
9/10Environmental situation to investigate
- The property is located in an established residential coastal suburb that appears generally free from major heavy industrial pollution or active landfill concerns.
- Buyers should investigate local environmental records to ensure there are no legacy industrial or waste management sites nearby, given the long history of urban development in the broader Dublin coastal zone.
Flood Safe
6/10Water overflow reports to follow up
- The property occupies an elevated coastal position along Seapoint Avenue, providing significant natural separation above immediate sea level which reduces direct tidal inundation risk.
- Proximity to Dublin Bay and the Seapoint shoreline means low-lying sections of the surrounding neighbourhood can occasionally face coastal vulnerability during extreme weather events and high tides.
- Map findings for this specific location could not be confirmed, meaning local surface water drainage and severe storm surges should be evaluated carefully during due diligence.
