What you'll like:

  • Prime coastal address: Situated in one of Dublin's most desirable locations, this property offers enduring lifestyle value and strong long-term capital appreciation for discerning buyers.
  • Exceptional site size: Occupying a generous 0.3-acre plot, the property provides rare breathing room and extensive outdoor space that is difficult to find in this urban setting.
  • Substantial garden length: The impressive rear garden extends approximately 168 feet by 50 feet, offering endless landscaping possibilities or substantial recreational space for families.
  • Detached bungalow layout: The rare double-fronted detached structure eliminates party-wall noise and provides a versatile, single-level living foundation with strong architectural character.
  • Period architectural charm: Built circa 1928, the home retains delightful original features such as high ceilings and classic fireplaces that add authentic character.
  • Dual aspect orientation: The favorable east-west orientation ensures fantastic natural light, with morning sunshine gracing the rear and afternoon light filling the front rooms.
  • Off-street parking: The mature front garden is set back from the road and includes generous parking capacity, ensuring convenience and security for multiple vehicles.
  • Substantial integrated garage: An adjoining garage and interconnecting storage shed provide excellent practical utility and secure storage space directly accessible from the main structure.
  • Independent rear access: The garage area provides potential rear entry, adding significant convenience and flexibility for future landscaping or construction machinery access.
  • Exciting renovation canvas: The existing 144 square meter floor area offers a brilliant blank slate for buyers looking to modernise and tailor a home to personal tastes.
  • Extension and development potential: The vast footprint and site size invite significant potential for major extensions or further site development, subject to planning permission.
  • Precedent for local development: Neighbouring properties demonstrate successful local expansions and developments, giving buyers encouraging indicators of what planning authorities might permit here.
  • Historic attic conversion: A legacy attic conversion with a dormer window and sink adds versatile bonus space that could serve various functional family needs.
  • Excellent DART connectivity: Positioned approximately 650 metres from Killester DART Station, the property guarantees effortless and swift commuting access into Dublin city centre.
  • Robust local bus routes: Numerous nearby bus options enhance public transport connectivity, making daily travel across the capital exceptionally convenient for all household members.
  • Proximity to coastal amenities: The magnificent Clontarf Promenade is close by, offering wonderful scenic walks, cycle tracks, and recreational seaside opportunities right on your doorstep.
  • St Anne's Park nearby: Enjoying easy access to one of Dublin's finest public parks provides immediate access to weekend markets, mature woodlands, and extensive sporting facilities.
  • Established village convenience: The charming villages of Killester and Clontarf are within easy reach, offering fantastic local cafés, gourmet restaurants, and everyday retail conveniences.
  • Strong educational network: Families will greatly appreciate the wide selection of reputable primary and secondary schools situated within comfortable walking and cycling distance.
  • Active price stability: The asking price has remained stable at 1,500,000 euros since tracking began, suggesting a firm vendor stance and realistic initial pricing strategy.

But keep in mind:

  • Extremely poor BER rating: The property holds a G energy rating, indicating severe thermal inefficiency that will necessitate urgent and comprehensive insulation upgrades.
  • Substantial energy upgrade costs: Achieving a modern comfortable living standard will require significant capital investment in retrofitting, heating systems, windows, and insulation.
  • Complete modernisation required: Virtually the entire interior requires gutting and updating, which will add substantial construction costs and project management overhead for the buyer.
  • Outdated bathroom facilities: The single family bathroom is dated and likely requires a complete refit to meet contemporary household standards and plumbing codes.
  • Limited existing bathrooms: Having only one bathroom for a potential three-bedroom family home creates a bottleneck that requires immediate reconfiguration or addition.
  • Historic attic compliance: The 1960s attic conversion should be checked by a surveyor to confirm whether it complies with current building regulations and fire safety standards.
  • Significant planning hurdles: Any major extension, reconfiguration, or proposed standalone dwelling at the rear will face stringent local planning scrutiny and potential delays.
  • Potential restricted rear development: While neighbours have developed, local planning policies can shift, meaning buyers should not take future planning permission for granted.
  • Garage structural condition: The substantial garage and storage sheds should be thoroughly inspected for damp, roof integrity, and asbestos roofing materials common to that era.
  • Plumbing and electrical overhaul: Given the 1928 construction date and subsequent piecemeal updates, the entire electrical wiring and plumbing infrastructure likely need total replacement.
  • Single-glazed windows risk: Original or older window installations may let in drafts and road noise, requiring immediate double-glazing investments to improve comfort.
  • High renovation inflation risk: Undertaking a major renovation project on a 144 square metre home exposes the buyer to current high construction material and labour costs.
  • Extended project disruption: Living through or managing an extensive structural renovation will cause significant temporary lifestyle disruption and require alternative temporary housing.
  • Vendor price firmness: The lack of asking price reductions since initial tracking indicates a motivated seller holding out for top market value, limiting early bargain potential.
  • High capital entry threshold: At 1,500,000 euros before renovation costs, the total financial exposure is very high, requiring careful budgetary contingency planning.
  • Potential boundary ambiguities: The extensive 0.3-acre site and long garden boundaries should be professionally verified by a surveyor to prevent future title or encroachment disputes.
  • Traffic and commuter congestion: Being located on Castle Avenue means experiencing regular commuter traffic peaks, which may impact quiet enjoyment during rush hours.
  • Surface water and drainage: Older properties on large mature plots should have their drainage systems and sewer connections camera-inspected to check for root ingress or blockages.
  • Roof structure timber health: The aging roof timbers should be carefully examined by a structural engineer for woodworm, dry rot, or sagging due to decades of weathering.
  • Damp and ventilation issues: Bungalows from this era often lack modern damp-proof courses, requiring vigilant inspection for rising damp, penetrating moisture, and poor sub-floor ventilation.

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 appears broadly in line, with a slight undervaluation signal.
  • The asking price appears fairly valued when considering the substantial underlying land value and exceptional development potential of the large 0.3-acre site, despite the low BER rating indicating significant modernisation costs are required for the existing dwelling.
  • Under-valuation signals are absent given the prime Clontarf location and rear access, whereas over-valuation signals stem from the very poor energy efficiency rating and outdated interior layout that will demand substantial capital investment from a buyer.
  • Support for this price point is provided by recent comparable transactions on the same street showing nearby properties commanding strong multi-million euro figures, while factors that could undermine the price include prohibitive renovation costs and lengthy planning delays.
  • Relevant market dynamics indicate that detached properties with expansive gardens in established coastal suburbs are exceptionally rare, meaning that developers and families seeking a long-term project will likely compete vigorously despite the initial poor condition.

Build Analysis

What we know from similar construction types

  • The property is a detached bungalow built circa 1928, retaining period features such as high ceilings and original fireplaces, alongside an attic conversion undertaken in the 1960s.
  • The 144 square meter floor area includes an adjoining substantial garage and interconnecting storage shed, offering practical storage and potential integration into the main dwelling.
  • Buyers should investigate the structural integrity, insulation levels, and compliance of the 1960s attic conversion, as building standards and regulations at that time differ significantly from current codes.
  • Given the age of the structure, potential purchasers should check for issues typical of properties from this era, such as outdated electrical wiring, plumbing, and potential dampness.
  • The listing highlights significant development and extension potential, including the possibility of extending over one or two floors or creating a standalone dwelling at the rear, making local planning policy, zoning, and precedent major factors for a buyer to verify with the local authority.

Retrofit Cost*

Possible renovating / insulating expenditure

  • The property has a BER rating of G, which indicates poor energy efficiency and necessitates a comprehensive deep retrofit.
  • A deep retrofit for a 144 square meter 1928 detached bungalow typically costs between EUR 70,000 and EUR 120,000, depending on the extent of works required.
  • Estimated costs should cover external wall insulation or internal dry-lining, upgrading the roof and attic insulation, replacing single or older double-glazed windows with high-performance units, installing a modern heat pump or high-efficiency heating system, and adding renewable energy systems such as solar panels to bring the energy rating up to a modern standard.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: 3,500 euro to 4,500 euro.
  • Explanation: Given the detached nature of the 144 square metre structure combined with a poor G energy rating and older construction characteristics, thermal efficiency is very low, leading to high potential heating demands that should be investigated by the buyer.

Flood Safe

Water overflow reports to follow up

  • The property is located in Clontarf, a coastal suburb of Dublin, meaning proximity to the coast and tidal influences should be considered when assessing long-term weather resilience.
  • Official mapping data currently shows no mapped flood areas directly affecting this specific site, indicating a generally favorable baseline position relative to known floodplains.
  • As a single-storey detached bungalow set at ground level, any potential localized surface water pooling during intense rainfall events would occur directly at living level rather than being elevated above lower storeys.

LifeFit Assessment

How well this property may suit your lifestyle

Family

7 areas
  • Young Children

    The property features an extensive 0.3-acre site with mature gardens offering a safe, enclosed outdoor environment for young children to play. Proximity to local parks and schools adds significant appeal, though the home requires substantial internal modernisation before it is fully suited to modern family living.

    7/10
  • Teenagers

    The generous plot size and proximity to local schools, sports clubs, and public transport links provide a practical base for teenagers. However, the current layout offers only limited independent living space, meaning substantial renovation would be necessary to accommodate growing adolescents comfortably.

    6/10
  • Multi-generational Living

    The expansive 0.3-acre plot and detached bungalow structure offer intriguing potential for extensive extension or separate garden development, subject to planning permission. The current single-level layout lacks distinct separate zones for multi-generational households without significant architectural redesign.

    6/10
  • Single Buyers

    With an asking price of €1,500,000 and a requirement for extensive modernisation—accentuated by a G energy rating—this property demands a significant capital outlay beyond the initial purchase price, making it less practical for typical single buyers.

    4/10
  • Couples

    The detached bungalow format in a highly sought-after seaside suburb offers an attractive long-term project for couples looking to craft a bespoke home. The expansive gardens and private setting provide a wonderful lifestyle backdrop, provided they have the budget and appetite for major renovation work.

    7/10
  • Empty Nesters

    Single-level bungalow living naturally appeals to those looking to avoid stairs for retirement or empty nesting. However, the property currently requires a complete overhaul to meet modern comfort and energy efficiency standards, which should be factored into long-term plans.

    7/10
  • Retirees

    The single-storey layout is well-suited for ageing in place, and the peaceful location near the coast and local amenities is ideal for retirees. Buyers should verify the extent of universal accessibility modifications required and budget for upgrading the poor BER rating.

    7/10

Work

3 areas
  • Remote Working

    The generous floor area and potential for home office setups within the existing structure or attic conversion provide a solid foundation for remote working, though high-speed broadband infrastructure should be verified.

  • Ageing in Place

    The single-storey detached bungalow design is fundamentally well-suited for ageing in place, though adapting the dated bathroom and layout for absolute accessibility should be verified.

    8/10
  • Low Maintenance

    The property requires extensive modernisation, carries a G energy rating, and features expansive mature grounds, meaning it will demand significant ongoing maintenance and capital investment in the near term.

    3/10
  • Secure Gated Entry

    While set back privately from the road with off-street parking, the front boundary currently lacks automated security gates, which a buyer would likely want to install.

    5/10
  • Minimalist Design

    Built c.1928 with traditional proportions, high ceilings, and period features, the property embodies classic character rather than sleek minimalist architecture.

    4/10
  • Flexible Floor Plans

    The generous footprint, attic conversion, and vast plot offer tremendous flexibility for redesign, reconfiguration, and extension to suit changing lifestyle needs.

    7/10
  • Heritage Home

    Retaining charm from its c.1928 construction—including original fireplaces and high ceilings—the home offers appealing period character alongside a need for comprehensive upgrading.

    7/10
  • Ecological Setup

    The current G energy rating indicates poor thermal performance and heavy reliance on fossil fuels, requiring a comprehensive green energy retrofit including insulation, heating, and glazing upgrades.

    2/10
  • Outdoor areas

    An exceptional 0.3-acre site featuring a rear garden measuring roughly 168 feet by 50 feet, combined with mature front gardens and dual east-west orientation, delivers outstanding outdoor space.
