But keep in mind:

  • Substantial financial commitment: The high asking price of eight hundred fifty thousand euros requires significant capital and robust mortgage structuring from potential buyers.
  • Potential rural isolation: Situated along a quiet country road near Portroe, daily reliance on private vehicular transport for shopping and schools is absolute.
  • Attic conversion compliance: Buyers should investigate whether the floored attic space secured proper planning permissions and building regulations for future habitable conversion.
  • On-site wastewater verification: Purchasers must verify the status, capacity, and percolation quality of the private septic tank or sewage treatment system.
  • Private water supply checks: If the property relies on a well, buyers need to commission comprehensive water quality and flow rate laboratory testing.
  • Lakeside microclimate wear: The exposed waterfront setting on Lough Derg may subject exterior paint, stonework, and joinery to accelerated weather-related degradation.
  • Maintenance of solar array: Buyers should inspect the operating condition and inverter health of the solar panels and battery storage installation.
  • High property insurance costs: Large detached homes in rural lakeside positions may attract higher premiums for home insurance against storm and water damage.
  • Elevated local property tax: The high market value band will result in significant annual Local Property Tax liabilities for the eventual homeowner.
  • Boundary fence verification: Purchasers should inspect official land registry maps carefully to confirm the exact boundaries encompassing the one-acre plot.
  • Boatshed planning status: Buyers need to check that the steel-framed boatshed complies fully with original agricultural or residential planning permissions.
  • Complex smart home wiring: Troubleshooting integrated Ethernet, intercom systems, and automated blinds could require costly specialist technician intervention if faults develop.
  • Extensive garden upkeep: Maintaining nearly an acre of formal lawns, mature planting, and external lighting will demand considerable weekly time or landscaping expenses.
  • Underfloor heating response: The zoned underfloor system may exhibit slower temperature response times compared to traditional radiator networks during sudden cold snaps.
  • Vaulted ceiling heating: The high volumetric space in the open-plan kitchen and living area could lead to rising heat accumulation and higher heating demands.
  • Private road maintenance: Buyers should clarify responsibility and cost-sharing agreements for repairing and maintaining the quiet country access road leading to the gates.
  • Zipline safety liability: The inclusion of a garden zipline introduces potential safety and liability considerations that warrant thorough inspection and insurance review.
  • B2 efficiency verification: While rated B2, buyers should review the original BER assessor report to identify any recommended upgrades for peak performance.
  • CCTV and alarm servicing: Security infrastructure requires regular professional servicing and battery replacements to ensure uninterrupted monitoring capabilities over time.
  • Single-level heating load: Heating a sprawling single-story bungalow of four hundred twenty-three square meters can result in substantial continuous energy consumption.

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 moderately overvalued compared with the available evidence.
  • The asking price appears somewhat elevated compared to local transaction trends, reflecting the exceptional scale, premium lakeside setting, and high-specification architectural features of the property.
  • Upward valuation signals stem from the expansive square footage, modern energy-efficient installations, extensive outbuildings, and prime waterfront amenities that significantly surpass typical regional housing stock.
  • Downward pressure or risk could stem from the relatively thin pool of buyers looking for luxury properties at this price point in a predominantly rural regional market, potentially limiting competitive bidding.
  • Supporting factors include the turnkey condition, advanced technological integration, and future conversion potential of the large attic, which justify a substantial premium over standard residential benchmarks.

Build Analysis

What we know from similar construction types

  • The property is a substantial detached bungalow extending to approximately 423-430 sq m of striking stone and rendered exterior construction, featuring vaulted ceilings, an open-plan kitchen, living and dining area, and extensive auxiliary buildings including a double garage and a steel-framed boatshed.
  • The home achieves a B2 BER rating and includes energy-efficient installations such as 18 high-output solar panels, a 10-kWh battery storage system, and zoned underfloor heating with individual room controls.
  • The property features an extensive floored attic area that has been wired and plumbed; a buyer should investigate compliance, planning permissions, and building regulations regarding any potential future living conversion of this space.
  • Given its prime waterfront setting on the shores of Lough Derg, a buyer should verify local flood history, coastal or lakeside erosion risk, and any specific environmental or planning restrictions that might apply to the grounds or outbuildings.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: €1,800 to €2,400.
  • Explanation: Despite the large floor area of 423 m², the property benefits from a strong B2 BER rating, zoned underfloor heating with individual room controls, and renewable energy inputs including 18 high-output solar panels and a 10-kWh battery storage system, which help moderate energy demands.

Pollution Safe

Environmental situation to investigate

8/10

Water overflow reports to follow up
