- Easy commuter access: Dublin city centre is located approximately 14 kilometres away, with nearby entry points to the M50 motorway facilitating broader travel.
- Future development potential: The half-acre grounds and expired planning permissions suggest potential opportunities for further residential enhancement or expansion, subject to local authority consent.
But keep in mind:
- Protected structure status: As a protected architectural structure, any future renovations, repairs, or modernization works will be subject to strict planning controls and specialized conservation requirements.
- Expired planning permissions: Previous planning grants for converting the garage into an independent residence have lapsed, meaning buyers must reapply and navigate current planning policies.
- Potentially high maintenance: Historic buildings featuring intricate architectural details, extensive stonework, and specialized systems often require higher ongoing maintenance budgets and expert tradespeople.
- Energy rating exemption: The listing notes no BER is provided due to protected status, leaving energy efficiency performance unverified and potentially requiring specialist insulation upgrades.
- Steep sloping topography: The elevated position and descending garden steps may present accessibility challenges for elderly residents, young children, or anyone with limited mobility.
- Substantial asking price: At €4,750,000, the property commands a premium market valuation that requires careful financial due diligence regarding future capital growth and liquidity.
- Complex glazing and joinery: Preserving original period windows and stained glass requires specialist restoration skills, which can significantly increase routine property upkeep costs.
- Potential drainage considerations: Coastal properties sitting on elevated slopes should be carefully evaluated for proper surface water runoff, guttering integrity, and sub-soil drainage.
- Traffic and access constraints: Narrow local Victorian-era roads surrounding Killiney Hill can experience congestion during peak school run times and busy summer beach weekends.
- Renovation cost uncertainties: Integrating modern services into a historic fabric can uncover hidden structural or damp issues, leading to unexpected repair expenses during refurbishment.
- Insurance cost variations: Insuring a high-value protected structure with specialized architectural features may incur higher-than-average premium quotes and specialized policy conditions.
- Garden maintenance demands: Maintaining approximately half an acre of mature grounds, lawns, and historical landscape features will require ongoing professional gardening support.
- Garage conversion dependencies: Capitalising on the detached garage space for independent living quarters depends entirely on securing fresh, unpredictable local planning approvals.
- Heating system efficiency: While gas-fired central heating and underfloor heating are present, integrating modern heat pumps or eco-friendly systems into a protected structure can be complex.
- Balcony weather exposure: Large elevated sea-facing balconies and terraces are exposed to strong coastal winds and salt spray, necessitating frequent cleaning and structural sealant checks.
- Restricted internal layout changes: Load-bearing historic walls and room layouts cannot be easily reconfigured due to conservation restrictions protecting the home's original interior integrity.
- Proximity to coastal elements: Being situated close to the sea increases exposure to salty air, which can accelerate exterior metal corrosion and paint deterioration if not regularly maintained.
- Boundary wall and gate upkeep: Automated security gates, extensive stone boundary walls, and long gravel driveways require regular mechanical and physical maintenance to remain functional.
- Limited ground-floor bedroom flow: Certain ground-floor bedrooms open directly toward external areas, which might require careful evaluation regarding privacy, security, and draft exclusion.
- Future development restrictions: While additional residential development is mentioned as a possibility, stringent local planning policies in Killiney heavily restrict sub-division of historic curtilages.
Price positioning
?
- The asking price appears somewhat ambitious when evaluated against broader regional transaction patterns, reflecting its niche architectural pedigree and prime coastal positioning rather than standard local averages.
- Signals supporting a higher valuation include historical provenance, a protected structure status, expansive coastal views, and extensive private grounds on a highly coveted residential avenue.
- Factors that could potentially undermine this premium asking price include the substantial ongoing maintenance typical of historic properties and the requirement for future capital expenditure to modernize specific living spaces.
- Overall price positioning aligns with ultra-prime coastal segments where unique architectural merit and scarcity value heavily dictate market expectations above conventional square-footage metrics.
Build Analysis
What we know from similar construction types
- The property is a Protected Structure of architectural distinction and historical importance, originally designed by the eminent Irish Gothic Revival architect George Coppinger Ashlin with connections to Augustus Welby Northmore Pugin.
- A buyer should investigate the specific statutory obligations, maintenance restrictions, and permission requirements associated with acquiring and modifying a Protected Structure in Ireland.
- The listing notes that planning permission was previously granted, though now expired, for garage conversion and potential further development within the grounds; a buyer should verify current local development policies regarding historical curtilage and future expansion potential.
- The BER rating is exempt due to the protected status of the building, meaning energy performance and potential thermal upgrade paths should be carefully assessed by a specialist familiar with period properties.
Heating cost*
Estimated expense to heat this property every year
- Estimated annual heating cost: €3,500 to €5,000.
- Explanation: With a floor area of 297 m² and gas-fired central heating including underfloor heating, energy consumption for a historic protected structure of this scale will be substantial, especially given older architectural features and high ceilings.
Pollution Safe
9/10Environmental situation to investigate
- The area is situated in an established residential coastal suburb well removed from heavy industrial zones, major manufacturing plants, or active commercial incinerators.
- Any historical or legacy industrial pollution risks appear minimal given the primarily residential and historical nature of Killiney Hill.
Flood Safe
8/10Water overflow reports to follow up
- The property occupies an elevated hillside position along St. George's Avenue, providing natural topographical protection against typical surface water flooding.
- While proximity to Killiney Beach offers coastal amenity, the elevated elevation significantly mitigates flood risk, though buyers should verify specific local drainage conditions.
