What you'll like:

  • Historic Victorian Character: Dating back to 1883, this detached residence offers unique architectural charm and period features that are increasingly difficult to find in newer housing developments.
  • Expansive Private Plot: Sitting on approximately 0.20 acres, the unusually large and secluded plot provides rare outdoor space for a property located in this established neighbourhood.
  • Desirable Coastal Location: Situated in Monkstown, residents enjoy close proximity to local seaside amenities, coastal walking routes, and the popular Forty-Foot swimming spot.
  • Excellent Village Amenities: The property is well-positioned near the vibrant villages of Monkstown and Blackrock, offering an extensive selection of boutique shops, cafés, and restaurants.
  • Strong Public Transport Links: The local DART network provides direct and efficient rail connections into Dublin city centre, enhancing convenience for daily commuters.
  • High Ceilings and Light: The interior benefits from impressive high ceilings and large windows that flood the primary living areas with generous amounts of natural light.
  • Open Plan Living Space: The kitchen and dining area provides a wonderful focal point with a striking fireplace and direct access to the rear gardens.
  • Seamless Indoor-Outdoor Flow: French doors open directly from the dining space onto the extensive gardens, creating an ideal layout for warm-weather entertaining.
  • Convenient Utility Room: A dedicated utility room fitted with plumbing and a skylight offers practical laundry space and extra storage separate from the main living zones.
  • Master Bedroom Garden Access: The primary bedroom features direct access to the rear gardens through a glazed door, along with a modern en-suite shower room.
  • Built-In Storage Solutions: Multiple bedrooms come equipped with built-in wardrobes, helping to maximize floor space and keep personal belongings neatly organized.
  • Attractive Architectural Façade: The property boasts an appealing period exterior featuring original cast iron gates and charming architectural details that enhance curb appeal.
  • Scope for Future Extension: The sizeable plot offers astute buyers substantial potential to extend the current footprint over time, subject to obtaining necessary planning permissions.
  • Recreational Club Proximity: The surrounding area is exceptionally well-served for sports enthusiasts, with local tennis, rugby, and sailing clubs situated nearby.
  • Major Road Access: Motorists benefit from convenient connectivity to the N11 and the broader south Dublin road network for travel across the region.
  • Established Residential Fabric: Being part of a historic neighborhood gives the property a strong sense of place and community identity that modern estates lack.
  • Ground Floor Bedroom Flexibility: The layout includes bedrooms on the ground level, which may offer useful flexibility for various living arrangements or mobility needs.
  • Stable Asking Price: The recorded asking price has remained firm at €895,000 without reductions, indicating steady seller confidence in the current market value.
  • Bus Network Coverage: Frequent Dublin Bus services operate throughout the surrounding area, providing alternative public transit options for getting around.
  • Individual Property Appeal: For purchasers seeking something genuinely distinctive, this dwelling stands out from standard suburban homes through its unique historical provenance.

But keep in mind:

  • Poor Energy Efficiency: The property carries a low BER rating of F with an energy performance of 446.83 kWh/m2/yr, indicating significant need for insulation upgrades.
  • Substantial Renovation Costs: Due to its 1883 construction date, the buyer should budget for modernizing structural elements, wiring, plumbing, and damp proofing.
  • Historic Preservation Constraints: Being a late Victorian building may impose local planning restrictions or conservation rules on how the exterior and interior can be altered.
  • Compact Floor Area: With a total floor area of roughly 94.34 square meters, the interior footprint is relatively modest for a detached three-bedroom house.
  • Small Second Bathroom: The en-suite shower room measures a compact 1.07m by 1.08m, which might feel quite cramped for daily use by occupants.
  • Small Third Bedroom: Bedroom two is relatively small at just 2.07m by 3.07m, limiting its versatility primarily to a single bedroom or home office.
  • Utility Room Constraints: The utility room is narrow at approximately 1.05m wide, which could restrict the types of laundry appliances that fit comfortably.
  • Unverified Services: The selling agent notes that all fixtures, fittings, and services are untested, requiring the buyer to commission independent professional inspections.
  • Potential Structural Wear: Older period properties often conceal hidden maintenance issues behind cosmetic finishes, necessitating a comprehensive pre-purchase structural survey.
  • Heating Upgrade Required: Given the F energy rating, the current heating system may be inefficient and expensive to run, requiring a likely upgrade to a modern heat source.
  • Planning Permission Uncertainties: Any future plans to extend the expansive plot or modify the historic structure will be subject to strict local planning approvals.
  • Static Pricing Strategy: The unchanging asking price history suggests the seller may have limited flexibility during early negotiations in the current market.
  • Single-Glazed Windows Risk: Period sash windows, while attractive, can lead to heat loss and drafts unless properly restored or retrofitted with secondary glazing.
  • Roof and Chimney Maintenance: An 1883 roof structure and original chimneys require careful professional assessment to check for tile degradation, flashing leaks, or structural sagging.
  • Potential Drainage Issues: Older properties on established plots may have outdated clay or cast-iron drainage systems that should be inspected via CCTV camera survey.
  • Parking Availability Unclear: The listing details do not explicitly confirm off-street parking capacity behind the attractive gates, which is a vital detail for drivers.
  • Garden Maintenance Demands: The expansive 0.20-acre plot will require considerable ongoing landscaping effort and financial investment to maintain or develop properly.
  • Boundary Wall Integrity: Buyers should verify the exact legal boundaries and the physical condition of all dividing walls and fences enclosing the large plot.
  • Lack of Property Type Details: The listing omits a clear classification of the exact legal property tenure, meaning buyers must investigate freehold versus leasehold status.
  • Moisture and Ventilation: High ceilings and older masonry can occasionally contribute to condensation or rising damp if proper ventilation and heating regimes are not maintained.

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 undervalued compared with the available evidence.
  • The asking price of €895,000 appears slightly conservative relative to recent local transaction benchmarks on the same road, where comparable properties routinely achieve higher figures despite similar architectural constraints and historical footprints.
  • Valuation signals are supported by a substantial plot size and late Victorian character, yet tempered by a poor energy rating which typically necessitates heavy capital expenditure for modern thermal efficiency improvements.
  • Downside risks include significant retrofit costs to upgrade the weak energy performance, while upside support stems from rare detached availability and potential development scope within the expansive gardens subject to planning.
  • Overall pricing strategy reflects a realistic entry point designed to attract competitive bidding, aligning reasonably well with historical acquisition costs while leaving adequate margin for necessary modernisation works.

Build Analysis

What we know from similar construction types

  • The property dates back to 1883, belonging to the late Victorian era, which means a buyer should investigate potential issues typical of older structures, such as original damp-proofing, timber rot, roof integrity, and the condition of original sash windows.
  • The floor area is approximately 94.34 square meters, and given its historical nature, a structural survey is strongly advised to assess the condition of internal walls, ventilation, and any historical alterations or extensions.
  • The property sits on a large plot of approximately 0.20 acres with expansive gardens, offering potential to extend subject to planning permission, though any future development plans would need to respect the historic character of the building.
  • Given the presence of historic elements and additions, a buyer should verify compliance and planning permission for any past extensions, structural changes, or utility installations.

Retrofit Cost*

Possible renovating / insulating expenditure

  • The property has a poor BER rating of F, indicating a high level of energy inefficiency and significant heat loss.
  • A comprehensive deep retrofit for a detached Victorian house of approximately 94 square meters typically requires extensive works, including external or internal wall insulation, roof insulation, upgraded high-efficiency heating systems, window restoration or replacement, and airtightness measures.
  • Estimated costs for a deep retrofit on a property of this size and vintage to bring it up to a modern energy standard generally range from 50,000 to 80,000 euros or more, depending on the extent of works required and specialist conservation constraints applicable to older structures.

Heating cost*

Estimated expense to heat this property every year

  • The estimated annual heating cost is between 2200 and 2800 euro.
  • Given the F BER rating and floor area of approximately 94 square meters, the property has a high energy consumption profile and potential thermal inefficiencies requiring investigation by the buyer.

Pollution Safe

9/10

Environmental situation to investigate

Flood Safe

8/10

Water overflow reports to follow up

  • The general area is situated at a reasonable distance from major coastal flood zones, though prospective buyers should review detailed local OPW flood maps.
  • Surface water management and drainage should be checked as part of standard pre-purchase structural surveys.

Family

7 areas
  • Young Children

    The property offers an expansive and secluded garden which is fantastic for young children to play safely outdoors, though parents should note the detached layout and proximity to Monkstown Avenue traffic. The 94.34 square metre floor area provides reasonable space, but buyers should investigate whether internal room configurations suit a growing family.

    7/10
  • Teenagers

    Teens will appreciate the independent feel of a detached late-Victorian home and the excellent connectivity to Dublin via the nearby DART network. However, with three bedrooms and a floor area of 94.34 square metres, living space may feel somewhat compact as children grow into young adults.

    6/10

    4/10
  • Single Buyers

    A single buyer seeking a unique period home with character will find the 1883 build deeply appealing, especially with village amenities nearby. However, managing a detached period home with a low BER rating of F requires dedicated maintenance and energy upgrade budgeting.
