But keep in mind:
- Extremely Poor BER Rating: The property carries a G energy rating, which indicates very high energy consumption and substantial thermal inefficiency that will require immediate upgrading.
- Immediate Retrofitting Costs: Due to the G energy rating, a buyer should budget for extensive insulation, heating system upgrades, and renewable energy integration to achieve acceptable comfort levels.
- Detached Bungalow Demand: Bungalows in this area often attract high competition and premium valuations, meaning buyers should carefully verify market value against the required renovation costs.
- Attic Conversion Limits: While the attic space is spacious with high ceilings, converting or extending it into formal habitable space remains strictly subject to obtaining planning permission.
- Upstairs Spiral Staircase: Access to the upper floor relies on a spiral staircase, which may present mobility challenges or difficulty when moving large furniture pieces.
- Upstairs Flooring Mix: The ensuite bathroom features laminate wooden flooring instead of tile, which buyers should inspect for potential water damage or wear over time.
- Garden Maintenance Requirements: The large mature garden with trees and shrubs will require ongoing gardening maintenance and professional tree care to keep it tidy.
- Busy Road Proximity: Situated on Avondale Road near Cluney Grove, the property may experience local traffic noise during peak commuting hours.
- Plumbing and Wiring Checks: Built in the 1950s, the underlying electrical wiring and plumbing systems should be thoroughly inspected by a professional for age-related deterioration.
- Roof Structure Inspection: Given the age of the original 1950s construction, a surveyor should closely examine the roof timbers and coverings for potential wear or damp.
- Planning History Verification: Any previous alterations or extensions to the footprint should be checked against local council planning records to ensure full regulatory compliance.
- Boundary Line Confirmation: Buyers should instruct their legal representative to verify all garden boundaries and title maps to prevent any potential disputes with neighbors.
- Surface Water Drainage: Given the mature trees and expansive lawn, buyers should check that surface water drains effectively away from the foundations during heavy rainfall.
- Ventilation and Damp: Older detached bungalows can be prone to condensation issues, making it vital to inspect window seals and wall ventilation during a survey.
- Storage Heater Replacement: If any legacy heating elements remain, they should be evaluated to ensure they meet modern safety and efficiency standards.
- Appliance Longevity: Built-in kitchen appliances should be tested during the survey process to determine whether they require imminent replacement or repair.
- Parking Gradient: Buyers should inspect the driveway slope and layout to ensure comfortable parking and turning space for three vehicles.
- Future Expansion Costs: While the listing highlights potential to extend, architectural and engineering fees for expanding a 1950s structure can add significantly to project budgets.
- Local Zoning Rules: Local planning policies in Killiney may restrict certain types of structural extensions or front-facing alterations, requiring careful consultation with an architect.
- Comprehensive Survey Necessity: Because of the G energy rating and 1950s build era, a detailed structural survey is strongly advised to uncover hidden maintenance liabilities before purchase.
Price positioning
?
- The asking price appears fairly positioned when compared against recent transactions along the same road, reflecting realistic expectations for a detached property of comparable dimensions within this highly sought-after suburban residential location.
- Positive valuation signals include spacious interior accommodation and an expansive west-facing rear garden, balanced by strong downward pressure stemming from the exceptionally poor energy rating which will necessitate immediate capital expenditure.
- The valuation is strongly supported by consistent local demand and proximity to excellent transport links, whereas significant potential for future modernization or extension underpins buyer interest despite substantial renovation requirements.
- Overall market sentiment remains buoyant for this specific neighborhood, suggesting that the current quoting figure captures an appropriate compromise between present condition deficiencies and long-term residential potential.
Build Analysis
What we know from similar construction types
- The property is a detached bungalow originally built in the 1950s, spanning approximately 183 square metres, which means buyers should investigate the condition of older structural elements, plumbing, and electrical systems.
- The BER rating is G, indicating poor energy efficiency and suggesting that the property will require significant insulation upgrades across external walls, the roof, and possibly floors.
- The listing notes a spiral staircase leading to the upper level and an attic room with high ceilings; buyers should verify whether all upper-floor conversions and alterations comply with current building regulations and planning permissions.
- The property features a large west-facing rear garden and offers potential to extend or further develop, though any major works will be subject to obtaining the relevant planning permissions.
Retrofit Cost*
Possible renovating / insulating expenditure
- Given the G BER rating and a floor area of approximately 183 square metres, a comprehensive deep retrofit is required to bring the property to a modern energy standard.
- The estimated cost for a full deep retrofit typically ranges from €70,000 to €100,000 or more, depending on the scope of works.
- Key interventions would include external wall insulation or internal dry-lining, attic and roof insulation, window and door replacements with high-performance double or triple glazing, upgrading the heating system to a renewable energy source such as a heat pump, and installing proper ventilation.

Estimated expense to heat this property every year
- Estimated annual heating cost: €3,500 to €4,500.
