What you'll like:

  • Detached bungalow layout: The single-story configuration offers accessible living and appeals heavily to downsizers or families seeking a flexible footprint for future life stages.
  • Generous plot size: The substantial site extending to approximately 0.27 acres provides rare outdoor space in this established residential suburb.
  • Superb extension potential: The large footprint and grounds offer immense scope to remodel and extend the existing accommodation, subject to planning permission.
  • Private rear garden: The magnificent south-east-facing rear garden is exceptionally private and not overlooked, creating a tranquil retreat for outdoor dining.
  • Established planting: The mature trees, shrubs, and established landscaping around the boundaries deliver an immediate sense of maturity and established privacy.
  • Long private driveway: The property is approached via a long driveway that enhances seclusion and provides an attractive buffer from the road.
  • Off-street parking: The front driveway provides excellent off-street parking facilities for multiple vehicles, which is a major convenience in this location.
  • Adjoining garage: The integrated garage offers secure parking or convenient storage, with potential to incorporate into future renovation plans.
  • Substantial basement: The property includes a basement extending beneath the floorplate, offering useful subterranean access and additional storage possibilities.
  • Desirable Blackrock address: Situated in a highly regarded residential location known for its leafy ambiance, strong community, and long-term property value retention.
  • Proximity to coast: The home is within easy reach of the delightful walks along Sandymount Strand and nearby coastal amenities.
  • Excellent public transport: The location is particularly well positioned for the N11 and QBC, providing quick and convenient access to Dublin City Centre.
  • DART station access: The DART station at Booterstown is readily accessible, offering fast commuter rail links across the capital.
  • Prestigious local schools: Many of South Dublin's most highly regarded schools are within easy reach, including Blackrock College and St. Andrew's College.
  • Proximity to universities: UCD Belfield is located nearby, making the address highly convenient for academics, staff, or university students.
  • Abundant local amenities: Easy reach of Blackrock, Booterstown, Donnybrook, and Ballsbridge offers an excellent selection of shops, cafés, and restaurants.
  • Recreational facilities: Close proximity to Elm Park Golf Club and various rugby clubs provides fantastic sporting and social outlets for residents.
  • Well-proportioned interior: The internal layout features a spacious entrance hall and good room proportions that provide a solid baseline for modernization.
  • Dual reception rooms: The property includes both a front dining room with a bay window and a rear sitting room opening onto the garden.
  • Natural light optimization: Sliding glass doors in the rear sitting room open directly onto the garden, bathing the living space in natural light.

But keep in mind:

  • Extremely poor BER rating: The property holds a G energy rating with a high energy performance indicator, requiring immediate and comprehensive thermal upgrades.
  • Heavy modernization required: The house would now benefit significantly from total modernization and upgrading across all internal fixtures and finishes.
  • Outdated heating system: Fitted with oil-fired central heating, a buyer should budget for a modern, high-efficiency heat pump or gas system.
  • Restricted basement height: The basement extending beneath the property has restricted head height, limiting its usability primarily to service access or basic storage.
  • Carpet throughout living areas: The presence of fitted carpet in key areas like the hallway and dining room may require removal or replacement during renovations.
  • Potential planning restrictions: Any major extension or remodeling plans will be subject to strict local planning permission guidelines in this suburban zone.
  • Renovation cost exposure: Given the G energy rating and dated condition, buyers must factor substantial capital expenditure into their total purchase budget.
  • Single bathroom limitation: The accommodation features only one family bathroom for three bedrooms, which may create morning bottlenecks for a family.
  • Suburban traffic congestion: Proximity to major transport corridors like the N11 can result in heavy commuter traffic during peak morning and evening hours.
  • Roof and insulation review: The attic hatch in the bathroom suggests older insulation standards that likely need complete upgrading to modern building regulations.
  • Single-glazed door elements: Some internal and external doors may require replacement to meet contemporary thermal and acoustic insulation standards.
  • Electrical system overhaul: Older properties requiring modernization often necessitate a complete rewiring to safely handle modern electrical and appliance loads.
  • Plumbing modernization needs: The existing kitchen and bathroom fittings are dated and likely require a complete refit along with upgraded pipework.
  • Window efficiency check: Existing windows should be inspected for thermal efficiency, as older double or single glazing will contribute to the poor BER score.
  • Boundary fence maintenance: Managing a 0.27-acre plot with mature trees requires ongoing landscaping maintenance and potential boundary fence repairs.
  • Basement moisture risk: Subterranean spaces with restricted access should be thoroughly investigated for dampness, drainage issues, and structural integrity.
  • Garage conversion complexity: While the garage offers potential, converting it into habitable space will require structural alterations and regulatory compliance.
  • Storage dependency: The reliance on external sheds for extra storage highlights a lack of built-in internal utility or attic storage space.
  • Kitchen layout limitations: The current kitchen layout is compact with laminate flooring and older cabinetry, requiring a complete redesign for modern living.
  • Bidet and sanitary wear: The presence of older fixtures like a bidet in the main bathroom indicates a dated layout ready for contemporary reconfiguration.

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 strongly overvalued compared with the available evidence.
  • The asking price appears overly ambitious given the significant capital expenditure required to upgrade the property from its current poor energy rating, with extensive modernisation needed across all internal areas to bring it up to contemporary living standards.
  • Valuation signals are mixed because while recent local transactions on the same street indicate strong baseline demand for sites in this premier suburb, this particular dwelling demands immediate thermal and structural remediation which heavily impacts overall market value.
  • Strong support for the asking price comes from the exceptionally large plot size and desirable south-east orientation, whereas potential buyers may be deterred by the substantial costs associated with achieving a modern energy efficiency rating.
  • Relevant market dynamics include proximity to top-tier educational institutions and excellent transport links, which consistently underwrite high property values in the immediate neighbourhood despite individual houses requiring comprehensive refurbishment before occupation.

Build Analysis

What we know from similar construction types

  • The property is a detached bungalow dating from an earlier construction era, featuring a ground-floor layout of approximately 108 square meters with an adjoining garage and a basement area with restricted head height.
  • Given the G BER rating, the building envelope likely lacks adequate insulation in the walls, roof, and floors, and features older single or double glazing that contributes to significant heat loss.
  • The heating system relies on oil-fired central heating, which should be inspected for efficiency, age, and compliance with current standards.
  • A buyer should investigate the structural integrity of the basement, check for any dampness or ventilation issues inherent to sub-floor structures, and assess the overall condition of the roof and electrical systems.
  • The generous 0.27-acre site offers significant potential to remodel, modernise, or extend the dwelling, though any major structural alterations or extensions will require professional architectural consultation and local authority planning permission.

Retrofit Cost*

Possible renovating / insulating expenditure

  • Estimated deep retrofit cost: €50,000 to €80,000.
  • Reasoning: The property has a G BER rating and an energy performance indicator of 383.27 kWh/m2/yr, indicating poor thermal performance. Bringing the property up to a modern B2 or A rating will require comprehensive fabric upgrades including external wall insulation or internal drylining, attic insulation, upgraded double or triple glazed windows and exterior doors, replacement of the oil-fired heating system with a heat pump or high-efficiency alternative, and installation of controlled ventilation.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: 3,000 to 4,500 euro.
  • Explanation: The property has a G energy rating and an oil-fired central heating system with a floor area of 108 square meters. Due to the very poor energy efficiency indicated by the BER rating, heating demands will be high until energy upgrades and insulation improvements are carried out.

Pollution Safe

9/10

Environmental situation to investigate

  • The property is located in an established residential suburb with no apparent close proximity to heavy industrial facilities, major waste incinerators, or active large-scale landfills.
  • Any historical industrial legacy or localized concerns in the broader coastal or suburban area should be independently verified by prospective buyers during standard environmental searches.

Flood Safe

8/10

Water overflow reports to follow up

  • The general Blackrock and Booterstown area sits within a largely established suburban environment, though coastal proximity means certain low-lying zones in the wider locality may warrant checks regarding surface water or tidal risks.
  • Buyers should consult detailed local authority flood maps and carry out comprehensive environmental surveys to confirm specific site vulnerabilities.

Family

7 areas
  • Young Children

    The property features an exceptionally large, private, and secure south-east-facing rear garden along with a generous front garden, making it a safe and wonderful space for young children to play. Proximity to top-tier local schools adds to its family appeal, though the house itself currently requires modernisation.

    8/10
  • Teenagers

    With three bedrooms and multiple reception rooms, there is decent space for teenagers, and the close proximity to DART services and Blackrock amenities offers good independence. However, the single-bathroom setup and current layout could feel somewhat restrictive for growing families.

    7/10
  • Multi-generational Living

    The single-level bungalow footprint is ideal for older family members who wish to avoid stairs. However, the existing three-bedroom, one-bathroom arrangement is relatively compact, meaning substantial remodeling or extending would likely be needed to comfortably accommodate multiple generations.

    6/10
  • Single Buyers

    At 108 m² on a large 0.27-acre site with an asking price of €995,000, this detached bungalow represents a significant capital outlay for a single buyer. Additionally, the extensive maintenance required for the large gardens and the poor G energy rating mean considerable extra investment and effort.

  • Retirees
