But keep in mind:

  • Low BER Rating: The recorded D2 energy rating indicates poor thermal efficiency, which will likely result in higher heating bills until significant insulation upgrades are completed.
  • High Energy Consumption: The energy performance indicator of 273.7 kilowatt-hours per square meter annually suggests that comprehensive retrofitting is needed for modern comfort.
  • Single Bathroom Limitation: Having only one bathroom for three bedrooms may create morning bottlenecks for a busy family, requiring potential costly plumbing additions.
  • Planning Permission Risks: Prospective buyers should verify if the substantial rear extension secured all necessary planning compliance and building control certification prior to purchase.
  • Garage Conversion Hurdles: Transforming the block-built garage into a habitable unit is subject to strict planning regulations, and approval should never be assumed without professional advice.
  • Upgrade Costs Required: Beyond the asking price, a buyer should budget for modernizing interior finishes, kitchen fittings, and bathroom fixtures to meet contemporary standards.
  • Heating System Efficiency: Older houses with lower energy ratings often feature dated boilers and radiators that may need immediate replacement to ensure reliability.
  • Window and Insulation Check: Buyers must inspect the age and condition of existing windows and roof insulation, as these likely contribute to the current poor energy score.
  • Extension Structural Audit: A thorough structural survey should investigate the junction between the original house and the rear extension to check for any settling or damp issues.
  • Boundary Verification: Legal advisors should carefully check the title deeds to confirm exact boundary lines, particularly regarding access paths and the rear garage footprint.
  • Traffic Congestion Concerns: Kill Avenue can experience heavy peak-time traffic, which may affect local commuting times and create noise considerations for front-facing rooms.
  • Parking Constraints: Depending on driveway layout and size, off-street parking might be limited for multiple vehicles, especially if the garage is used for storage.
  • Garden Maintenance Needs: The private rear garden, while desirable, will require ongoing landscaping and upkeep to maintain its sunny and appealing condition.
  • Work Space Compliance: Buyers intending to use the extra work space for a business should check local zoning rules and building regulations regarding commercial use.
  • Drainage and Plumbing Survey: An independent drain survey is recommended to check the condition of underground pipes, especially given the age of the original structure.
  • Ventilation and Dampness: Extended properties sometimes suffer from restricted airflow, making it wise to check for signs of condensation or damp in the extended zones.
  • Roof Condition Inspection: The main roof and extension roofing should be professionally examined to estimate remaining lifespan and prevent unexpected leak repair costs.
  • Electrical Wiring Age: Buyers must verify whether the electrical fuse board and wiring have been updated to modern safety standards to handle current appliance loads.
  • Storage Limitations Inside: Despite the extension, the single-bathroom layout and lack of integrated closet space in older rooms may necessitate creative storage solutions.
  • Market Competition Pressure: Due to the popularity of this south Dublin suburb, interested buyers should be prepared for competitive bidding environments and swift action.

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 slightly overvalued compared with the available evidence.
  • The asking price appears somewhat elevated relative to recent local transactions, suggesting it might be slightly overvalued when compared against historical completed sales data within the immediate neighborhood.
  • Upward pricing signals are driven by the property's substantial floor area, extended living spaces, and additional features like a block-built garage, whereas downward signals come from the modest D2 energy rating requiring potential upgrades.
  • Strong buyer demand in this premier south Dublin suburb and potential to convert the outbuilding could support the target figure, though broader economic headwinds and necessary retrofitting costs might undermine buyer enthusiasm.
  • Overall, the positioning reflects a premium for extended family accommodation in a highly sought-after location, placing it moderately above the baseline established by recent comparable neighborhood activity.

Build Analysis

What we know from similar construction types

  • The property features a substantial rear extension that increases the overall floor area to 124 m², so a buyer should verify that appropriate planning permission and building regulations compliance were obtained for this work.
  • A separate block-built garage and an additional workspace are present, offering potential for conversion subject to planning permission and building regulations.
  • The BER rating is D2 with an energy performance indicator of 273.7 kWh/m2/yr, indicating that the fabric of the building and heating systems are inefficient by modern standards and likely require significant insulation upgrades.

Retrofit Cost*

Possible renovating / insulating expenditure

  • Given the D2 BER rating and a floor area of 124 m², a comprehensive deep retrofit to bring the property to a modern B2 standard or higher would likely cost between EUR 45,000 and EUR 65,000.
  • This estimated cost would cover external wall insulation or internal dry-lining, upgraded double or triple-glazed windows and exterior doors, roof insulation improvements, and the installation of a renewable heating system such as a heat pump, though actual costs will depend on specific contractor quotes and detailed energy surveys.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost is approximately €1,800 to €2,300.
  • This is based on the 124 m² floor area and the D2 energy rating, which indicates lower energy efficiency and higher heat loss compared to modern homes, meaning the buyer should investigate potential insulation upgrades.

Pollution Safe

8/10

Environmental situation to investigate

  • The area is predominantly residential and suburban, appearing well removed from heavy industrial sites, major modern landfills, or active waste incinerators.
  • Any historical industrial uses or localized waste management concerns in the broader south Dublin region should be independently verified by prospective buyers if desired.

Flood Safe

8/10

Water overflow reports to follow up

  • The location sits on elevated suburban terrain well away from major coastal flood zones or major river flood plains.
  • Standard localized surface water pooling during heavy rainfall events should be verified with local drainage checks.
