What you'll like:

  • Prime parkside location: Situated directly adjacent to Marlay Park, this home offers immediate access to popular weekend markets, walking trails, and family recreational facilities.
  • Substantial detached footprint: Providing 148 square meters of interior space, this detached family residence ensures excellent separation of rooms and long-term accommodation flexibility.
  • Garage conversion versatility: The converted garage space serves effectively as an additional downstairs lounge, playroom, or home office depending on the family lifestyle requirements.
  • Exceptional privacy levels: The large, mature rear garden is well-screened with established trees and shrubs, creating a secluded outdoor sanctuary away from neighboring eyes.
  • Generous off-street parking: A spacious cobblelock driveway at the front provides convenient parking space for multiple vehicles, avoiding street congestion hassles.
  • Highly regarded schools: The property sits within close proximity to prestigious educational institutions like Wesley College, Loreto Beaufort, and St. Columba's College.
  • Robust transport connectivity: Residents benefit from nearby Dublin Bus routes, easy proximity to the M50 motorway, and the LUAS tram line at Balally.
  • Established residential enclave: Pine Valley is widely recognized as a peaceful, mature, and family-friendly neighborhood characterized by generous green open spaces.
  • Proximity to retail hubs: Dundrum Town Centre and local shopping facilities in Ballinteer are just minutes away, offering extensive retail, dining, and entertainment options.
  • Strong sporting amenities: The surrounding area boasts numerous active clubs, including Ballinteer St. John's GAA and Stackstown Golf Club for recreation enthusiasts.
  • Well-proportioned bedrooms: Upstairs features four spacious bedrooms, three of which are comfortable doubles with built-in wardrobe storage solutions already installed.
  • Functional utility configuration: A dedicated utility room with tiled floors and built-in cabinets offers direct access to both the rear garden and garage space.
  • Flexible ground layout: The layout includes a wide entrance hall, a separate guest WC, and interconnecting reception rooms that create a smooth flow for entertaining.
  • Carefully maintained interior: The house has been meticulously cared for over the years, presenting buyers with a clean and tidy condition ready for immediate occupation.
  • Future development potential: The generous plot size and detached structure offer excellent scope for further structural expansion or extensions, subject to planning permission.
  • Natural light distribution: Large windows throughout the property maximize daylight penetration, particularly in the dining area and kitchen overlooking the private garden.
  • Quiet cul-de-sac appeal: Positioned along a tree-lined avenue within a low-traffic zone, the address ensures a safe, tranquil environment for children playing outdoors.
  • Solid construction era: Built within an established Dublin suburb, the property benefits from traditional construction methods and a proven neighborhood track record.
  • Outdoor storage access: The integration between the utility room, garage, and rear garden optimizes day-to-day household logistics and equipment storage capabilities.
  • Investment preservation: Detached homes in Rathfarnham near major parks historically retain strong market value and long-term capital appreciation potential.

But keep in mind:

  • Poor energy rating: The property holds a weak BER rating of F, which indicates very high energy inefficiency and substantial heat loss throughout.
  • Substantial upgrade costs: Bringing the energy performance up to modern standards will likely require major capital investments in insulation, heating, and windows.
  • High heating bills: Due to the F rating, future occupants should anticipate heavy winter heating expenses until comprehensive thermal retrofits are completed.
  • Outdated bathroom fixtures: The single family bathroom on the first floor may require complete modernization to align with contemporary aesthetic and functional preferences.
  • Renovation budget required: Beyond cosmetic updates, buyers should budget for structural energy improvements to make the house comfortable by modern expectations.
  • Planning permission hurdles: Any future plans to extend the property or alter the garage conversion will require navigating local council planning regulations.
  • Single bathroom constraint: Having only one main upstairs bathroom plus a downstairs guest WC may create morning bottlenecks for a busy four-bedroom household.
  • Potential wiring updates: Older homes in mature estates often feature legacy electrical wiring that should be thoroughly inspected by a qualified electrician.
  • Plumbing system evaluation: The existing plumbing and boiler infrastructure should be carefully checked during pre-purchase surveys to rule out hidden aging defects.
  • Window efficiency concerns: Original or older window installations may contribute significantly to the poor energy score and require full replacement.
  • Attic insulation check: Buyers must verify the depth and quality of current attic insulation, as an F rating often points to inadequate roof space defense.
  • Ventilation and dampness: Low energy ratings can sometimes lead to condensation risks, meaning proper ventilation checks are essential during the due diligence phase.
  • Traffic and event congestion: Proximity to Marlay Park means local roads and access routes can experience temporary heavy traffic during major concerts and events.
  • Competitive micro-market: Properties in this specific estate generate steady demand, requiring buyers to move quickly and decisively during negotiations.
  • Upstream maintenance liabilities: Mature trees in the rear garden and surrounding estate require regular professional pruning to prevent root or branch interference.
  • Roof structure inspection: The condition of the roof timbers and tiling should be professionally verified given the maturity of the residential development.
  • Surface water drainage: Prospective buyers should inspect the garden and driveway drainage systems to ensure heavy rainfall runs off effectively without pooling.
  • Boundary line verification: Legal advisors should carefully check the title deeds and boundary markers to confirm exact property lines against the physical layout.
  • Boiler replacement timeline: The current heating boiler age is unspecified, meaning a replacement unit could become an unexpected near-term capital expense.
  • Insurance premium variations: Homes with very poor energy ratings can occasionally face higher insurance underwriting scrutiny or conditional policy terms.

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.
  • Recent verified transactions on the same estate show comparable semi-detached and detached homes achieving robust sale prices, including a nearby property fetching nine hundred and seventy thousand euros in mid-twenty-twenty-six.
  • The asking price of nine hundred and fifty thousand euros aligns closely with recent local market activity, where similar family residences in the immediate area have traded between nine hundred thousand and one million euros.
  • The property features a substantial floor area of one hundred and forty-eight square meters with a garage conversion, matching the scale of established four-bedroom homes that command strong buyer demand in this neighborhood.
  • Potential buyers should investigate the implications of the poor energy rating of F, as upgrading the thermal efficiency and heating systems will likely require significant capital expenditure following purchase.

Build Analysis

What we know from similar construction types

  • The property is a substantial four-bedroom detached family home with a floor area of 148 m², featuring a previous garage conversion and a separate versatile lounge room.
  • Given the F BER rating and mature nature of the Pine Valley estate, a buyer should investigate the existing thermal envelope, including attic insulation, wall construction type (cavity vs. solid), and window performance.
  • The presence of a garage conversion and scope for further development mean a buyer should verify that all past structural changes and potential future extensions comply with local planning regulations and building control standards.
  • The layout includes a utility room with direct access to the rear and a ground-floor guest WC, requiring checks on plumbing integrity, drainage, and ventilation.
  • A thorough structural survey is recommended to assess the condition of the roof, timber structures, and damp proofing given the home's energy rating and age.

Retrofit Cost*

Possible renovating / insulating expenditure

  • The property holds an F BER rating, indicating a heavy reliance on energy and poor thermal efficiency across a 148 m² detached footprint.
  • A comprehensive deep retrofit to bring the home up to a modern B2 rating or higher typically ranges from €40,000 to €70,000 gross before applicable Sustainable Energy Authority of Ireland (SEAI) grants.
  • Costs will scale based on the need for external wall insulation suited to a detached home, window and door replacements, airtightness improvements, attic insulation, and the installation of a low-temperature heating system like a heat pump alongside solar PV panels.
  • Available SEAI grants and One Stop Shop incentives can significantly reduce the net upfront capital required, though a detailed Home Energy Assessment is recommended to lock down exact quotes.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: €3,500 to €5,000.
  • Explanation: The property features a floor area of 148 m² combined with a low BER rating of F, indicating poor thermal insulation and higher heat loss, which results in elevated energy consumption to maintain a comfortable indoor temperature during colder months.

Pollution Safe

9/10

Environmental situation to investigate

  • The property is located in a predominantly residential suburb with minimal heavy industrial activity nearby.
  • Buyers should verify local environmental records for any legacy concerns, though the immediate area appears largely clean and well-removed from major industrial pollution sources.

Flood Safe

8/10

Water overflow reports to follow up

  • The general location sits at the foothills of the Dublin Mountains, elevation typically mitigating widespread coastal or major riverine flood risks.
  • Buyers should investigate local surface water drainage patterns and check detailed Office of Public Works (OPW) flood maps to confirm minor localized risks.
