What you'll like:

  • Prestigious location: Situated on a highly sought-after, tree-lined thoroughfare close to Clontarf Castle, ensuring long-term desirability and strong neighborhood prestige for the incoming resident.
  • Historic redbrick architecture: The late 1920s double-fronted exterior showcases timeless period charm and elegant proportions that cannot be easily replicated in modern developments.
  • Substantial plot size: Occupies an unusually generous plot of approximately 0.12 acres, providing exceptional outdoor space and considerable scope for future development.
  • Westerly rear garden: The impressive 80-foot garden benefits from a favorable westerly aspect, maximizing afternoon and evening sunlight for outdoor relaxation.
  • Valuable rear access: Features convenient vehicle or pedestrian access directly from Victoria Road, facilitating easier construction works and off-street parking alternatives.
  • Generous floor area: Spanning approximately 210 square meters, the substantial layout offers ample room for large family living without feeling cramped.
  • Period interior features: Preserves wonderful character details including a picturesque covered porch, stained-glass doorway, and traditional open fireplaces.
  • Versatile reception spaces: Includes multiple interconnected living and dining areas that provide flexible configurations for modern family gatherings and entertaining guests.
  • Sunroom extension: A 1990s sunroom successfully bridges the interior living zones with the mature rear garden, enhancing natural light intake.
  • Integral garage: Provides secure off-street parking and immediate indoor storage capacity, which is a rare and coveted convenience in this urban coastal suburb.
  • Sweeping front driveway: A private cobble-style driveway delivers excellent off-street parking for multiple vehicles while maintaining a secluded front boundary.
  • Mature landscaping: Established greenery and mature hedging create a profound sense of privacy and tranquility across both front and rear grounds.
  • Five spacious bedrooms: Offers four double bedrooms and one single room, easily accommodating larger families or providing dedicated work-from-home options.
  • Dual family bathrooms: Two side-by-side first-floor bathrooms provide practical convenience and interesting reconfiguration potential into modern ensuites.
  • Proximity to promenade: Located just moments from the scenic Clontarf Promenade, offering residents immediate access to coastal walks and open marine views.
  • Nearby St Anne's Park: Being within easy reach of St Anne's Park gives families access to magnificent green spaces, weekend markets, and recreational sports grounds.
  • Exceptional city connectivity: Positioned only 4.5 kilometers from Dublin City Center with numerous local bus routes servicing the immediate area.
  • Strong local amenities: Surrounded by a thriving community of popular restaurants, boutique cafes, local shops, and established sports clubs.
  • Renovating potential: Represents a supreme blank canvas for a new owner to undertake a comprehensive modernization program tailored to personal tastes.
  • Endless extension scope: Offers significant potential for a contemporary rear extension subject to obtaining the necessary planning permissions.

But keep in mind:

  • Extremely poor BER rating: The property holds an F energy rating, which will necessitate significant capital investment in insulation, windows, and heating systems.
  • Substantial modernization required: Having remained in the same family ownership for decades, the entire interior requires a costly and comprehensive refurbishment program.
  • Outdated extension layouts: The 1960s kitchen, breakfast room, utility, and bathroom extension likely require complete demolition or redesign to suit contemporary lifestyles.
  • Significant heating costs: Poor energy efficiency will likely result in high winter heating bills until deep-retrofitting works are successfully completed.
  • Asbestos risk assessment: Given the era of previous extensions built in the 1960s, buyers should verify the presence of hazardous materials before starting demolition.
  • Plumbing modernization needs: First-floor bedrooms feature outdated sink units that indicate aging pipework requiring a comprehensive plumbing overhaul throughout the house.
  • Electrical rewiring required: Older properties of this vintage often feature outdated wiring systems that must be completely upgraded to meet modern safety standards.
  • Roof structure inspection: The roof timbers and coverings of a 1920s home require thorough professional inspection to check for leaks, rot, or failing slates.
  • Planning permission hurdles: Any major alterations, modern extensions, or structural changes to a prominent period home may face strict local planning scrutiny.
  • High renovation budget: Buyers must factor in substantial contingency funds well beyond the purchase price to handle unexpected structural and cosmetic issues.
  • Disruption during works: Undertaking a deep retrofit on 210 square meters of living space will likely require alternative temporary accommodation during the construction phase.
  • Window replacement costs: Original or older windows likely lack double glazing, demanding a full house window replacement to improve thermal comfort and noise insulation.
  • Damp and ventilation checks: Older solid or semi-detached redbrick walls should be checked by a surveyor for rising or penetrating damp due to historical lack of cavity insulation.
  • Drainage survey necessity: Aging underground drainage systems connected to the 1960s extensions should be camera-surveyed to prevent future structural subsidence risks.
  • Restricted front layout: While the driveway is generous, the integration with the garage may limit turning space for larger modern SUVs.
  • Boundary verification needed: Buyers should instruct their legal team to meticulously verify the exact legal boundaries along the extensive 80-foot garden and Victoria Road access.
  • Local parking congestion: Castle Avenue can experience heavy traffic volumes during peak commuting hours, potentially complicating vehicle egress from the driveway.
  • Conservation considerations: While not explicitly noted as a protected structure, local area guidelines may still restrict external alterations to preserve the streetscape.
  • Upgrading bathrooms: The existing dual bathroom layout requires complete gutting and redesign to meet contemporary sanitary and waterproofing expectations.
  • High upfront capital: Combining the high asking price with mandatory energy upgrades means the total acquisition and improvement cost is substantial.

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 mildly undervalued compared with the available evidence.
  • The asking price appears somewhat undervalued given the substantial floor area and prime location, though the poor energy rating requires significant capital expenditure for modernisation.
  • Signals pointing towards higher underlying value include the generous plot size, historical architectural character, and strong historical transactions for comparable houses along this thoroughfare.
  • Conversely, the heavy investment needed to upgrade the energy rating and internal configuration could strongly undermine immediate affordability and deter prospective buyers.
  • Overall, the pricing reflects a balanced discount for the required retrofitting costs while acknowledging the premium address and extensive development potential available.

Build Analysis

What we know from similar construction types

  • The property is a historic, double-fronted semi-detached redbrick house built in the late 1920s, featuring period architecture, a covered porch, and a stained-glass doorway.
  • Extensions were added in the 1960s (kitchen, utility, bathroom, breakfast room) and the 1990s (sunroom), meaning a buyer should investigate the structural integrity, insulation standards, and compliance of these various phases of construction.
  • Given the 1920s origin and subsequent additions, a comprehensive structural survey is recommended to assess potential issues typical of older properties, such as dampness, outdated wiring, plumbing, and ventilation.
  • The property sits on a generous 0.12-acre plot with rear access off Victoria Road and an integral garage, offering significant potential for modernization and extension, subject to obtaining necessary planning permissions.

Retrofit Cost*

Possible renovating / insulating expenditure

  • The property has a poor BER rating of F and a substantial floor area of approximately 210 square meters.
  • Bringing a property of this size and age up to a modern energy-efficient standard (such as a BER rating of B2 or higher) would require a deep retrofit.
  • A comprehensive deep retrofit including external or internal wall insulation, roof insulation, upgraded windows and doors, and the installation of a renewable heating system such as a heat pump is estimated to cost between 90,000 and 130,000 euros, depending on the scope of works and contractor pricing.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: €3,500 to €4,500.
  • Short explanation: Due to the poor F energy rating, large 210 square metre floor area, and older period construction, the property will have high thermal losses requiring significant energy consumption until extensive upgrades and retrofitting are carried out.

Pollution Safe

9/10

Environmental situation to investigate

  • The area is primarily residential and established, showing little proximity to heavy industrial pollution or active incinerator facilities.
  • Any legacy industrial concerns or localized commercial impacts appear minimal, though buyers should verify historical land uses during structural due diligence.

Flood Safe

8/10

Water overflow reports to follow up

  • While the broader coastal district of Clontarf features zones susceptible to tidal or coastal flooding closer to the seafront, inland locations along Castle Avenue generally maintain a more elevated position.
  • Prospective purchasers are advised to consult detailed local authority flood maps and carry out environmental searches to verify precise site risk.
