But keep in mind:
- Substantial asking price: At nearly 2.38 million euros, buyers must carefully evaluate whether the square footage and specific location command such a high market valuation.
- Potential modernization costs: While refurbished in 2003, buyers should budget for possible updates to interior decor, bathrooms, or kitchen finishes to match contemporary personal tastes.
- Maintenance responsibilities: Managing approximately 0.3 of an acre of mature gardens requires significant ongoing physical upkeep or regular professional landscaping expenditures by the homeowner.
- Traffic congestion risks: Proximity to a busy village center may occasionally expose the property to peak-hour traffic bottlenecks, school run congestion, and associated noise levels.
- Eaves storage limitations: Bedrooms two, three, and four rely on eaves storage access, which can restrict standard furniture placement and reduce usable bedroom floor space.
- Single-pane considerations: Buyers should verify the exact double-glazing specifications across all windows to ensure optimal acoustic insulation from nearby neighborhood street activities.
- Boiler efficiency checks: The dedicated double-door boiler house contains heating infrastructure that requires thorough professional inspection to confirm remaining lifespan and operational efficiency.
- Flat roof maintenance: Architectural elements such as ceiling roof lights and modern extensions demand regular inspection for waterproofing integrity and potential drainage issues over time.
- Boundary wall upkeep: Extensive private grounds bounded by walls or fencing require periodic inspection to ensure structural security and clear demarcation of property lines.
- Drainage inspection needed: Buyers should commission a professional CCTV drain survey to check subterranean stormwater and sewage pipes across the large site for blockages.
- Electrical system audit: Given the scale of the residence, an independent electrical safety audit is recommended to confirm the switchboard and wiring meet modern standards.
- Roof insulation verification: While the BER rating is favorable, verifying the depth and quality of attic and roof insulation will ensure maximum long-term thermal efficiency.
- Planning compliance checks: Any historical extensions or alterations completed during past refurbishments should be cross-referenced against local council planning records for full compliance.
- Property tax tier: The high capital value places the home in the highest bracket of local property tax obligations, adding to annual fixed ownership overhead expenses.
- Insurance cost variations: Larger detached properties with extensive gardens can incur higher buildings and contents insurance premiums compared to standard semi-detached dwellings.
- Garage conversion potential: While functional as a games room, buyers planning future residential conversions should verify local planning restrictions and building control regulations.
- Security system upgrade: Although electric gates are installed, new owners may wish to invest in upgraded smart alarm systems and CCTV for enhanced peace of mind.
- Radon gas testing: Buyers should inquire about local radon testing data or conduct independent measurements, as certain regions in Dublin require proactive mitigation steps.
- Future expansion limits: The footprint already spans a significant portion of the plot, meaning major future architectural extensions might be restricted by local planning guidelines.
- Market liquidity factors: Luxury properties at this high price tier typically experience longer selling cycles, making future resale liquidity an important financial consideration.
Price positioning
?
- The asking price of €2,375,000 appears positioned at a notable premium relative to historical local transactions on the same street, reflecting its substantial floor area and extensive private grounds.
- Valuation signals are supported by recent high-value residential transactions within the wider neighbourhood, demonstrating a strong regional demand for well-maintained detached family properties.
- Factors that could support such an ambitious pricing include the generous 0.3-acre site, a strong B energy rating, and close proximity to the village center and the Phoenix Park.
