- Modern shaker kitchen: The stylish kitchen and dining room features contemporary shaker-style cabinetry, tiled splashbacks, and ample storage space designed to easily accommodate modern culinary needs.
- Stylish sanitaryware: Both the main house bathroom and the separate apartment bathroom feature sleek modern designs equipped with premium walk-in showers and heated towel rails for added luxury.
- Convenient city accessibility: Located only four kilometres from Dublin City Centre, the address ensures exceptionally easy commuting times for working professionals utilizing nearby public transportation networks.
- Rapid motorway connections: Proximity just one kilometre from the M50 motorway allows motorists to swiftly access national road routes and Dublin Airport without enduring prolonged suburban traffic bottlenecks.

- Excellent educational options: Families will benefit from a fantastic surrounding choice of well-regarded national and secondary schools situated within convenient daily travelling distance of the address.

- Landscaped outdoor dining: The professionally landscaped back garden includes a lovely designated outdoor dining area, making it an ideal setting for hosting gatherings during warm summer months.
- Bright entrance hallway: Access is gained through a bright and spacious entrance hallway that immediately sets an inviting and airy tone for the rest of the dwelling.
- Cozy family living room: The main living room provides a generous family gathering area featuring a cozy electric fireplace as a stylish central focal point for relaxing evenings.
- Stable asking price: The recorded asking price history shows no numerical changes, indicating a firm initial pricing strategy by the vendor in line with current market expectations.
- Deceptively spacious layout: Clever architectural utilization of the period footprint provides unexpected depth and room dimensions that defy the modest external cottage appearance.
- Strong rental potential: The combination of a primary four-bedroom home and a separate standalone one-bedroom annex creates dual-income or flexible family accommodation rarely found in this specific corridor.
But keep in mind:
- Moderate energy rating: The property holds a C energy rating, which means buyers should budget for potential future insulation or heating upgrades to improve thermal efficiency and lower energy bills.
- Unverified planning compliance: Buyers must instruct their legal representatives to verify that full planning permission and building regulations were secured for the large rear self-contained apartment.
- Potential extension limitations: Due to the protected or established nature of period cottage clusters, future structural alterations or extensions might face strict local planning authority restrictions.
- Boundary clarification required: Purchasers should carefully examine the title deeds to confirm exact boundary lines for the long back garden backing onto the Phoenix Park perimeter.
- Maintenance of secondary unit: Owning a separate self-contained apartment introduces ongoing maintenance liabilities and appliance upkeep responsibilities beyond the standard requirements of a single family dwelling.
- Potential rental regulations: Anyone considering letting the rear apartment must investigate current rent pressure zone caps and residential tenancy board compliance obligations thoroughly prior to purchase.
- Traffic congestion exposure: Positioned near major arterial routes like the Navan Road, the property may experience elevated traffic noise levels and congestion during peak commuting hours.
- Historic property upkeep: As a modernised period cottage, the building may require specialized maintenance techniques and higher ongoing upkeep costs compared to a newly constructed contemporary home.
- Single-pane retention risk: Buyers should verify whether any original period windows remain and whether they require upgrading to modern double glazing to eliminate drafts.
- Electrical capacity check: The integration of a separate apartment and modern high-draw appliances means buyers should commission an independent electrical survey to verify consumer unit capacity.
- Heating system efficiency: The reliance on individual electric fireplaces and standard heating configurations should be inspected to ensure running costs remain manageable across both structures.
- Drainage infrastructure age: Older cottages in this corridor can sometimes feature legacy clay drainage pipes that warrant a specialized CCTV survey to prevent unexpected blockage issues.
- Lack of off-street parking: The listing details do not explicitly confirm dedicated private driveway parking, so buyers must verify local parking permits or roadside vehicle storage options.
- Garden privacy screening: While the south-facing back garden is large, buyers should inspect existing boundary fencing and hedging to ensure adequate privacy from adjacent neighboring properties.
- Roof condition verification: The expanded layout and older vernacular structure mean a thorough professional roof inspection is essential to check for adequate ventilation and slate integrity.
- Insurance cost variations: Insuring a property featuring a secondary independent dwelling unit may incur specialized policy terms or higher premiums that require prior broker consultation.
- Surface water management: Given the extensive hard landscaping in the front and rear gardens, buyers should confirm that proper surface water drainage prevents pooling near foundations.
- Internal soundproofing: When utilizing the rear unit for guests or tenants, buyers should check the acoustic insulation between the main bedroom connection point and the apartment.
- Future development surrounding: Buyers should review local development plans to ensure that no nearby commercial or high-density residential projects will impact the tranquil parkside setting.
- Asking price negotiation room: The static asking price history suggests the vendor may hold firm expectations, potentially limiting aggressive initial discounting during the bidding process.
Price positioning
?
- The asking price of €695,000 appears notably elevated relative to standard benchmarks for a semi-detached property of this size, largely driven by the inclusion of a fully modernized separate one-bedroom rear apartment and a highly desirable location directly backing onto the Phoenix Park.
- Upward valuation signals stem from the comprehensive high-spec interior renovations, landscaped outdoor spaces, and dual-accommodation layout which effectively offers a primary residence alongside potential rental income, contrasting with smaller neighbourhood comparables that lack these premium additions.
- Strong buyer demand in this premier north Dublin corridor could support such an ambitious figure, though potential overvaluation risks might be undermined if prospective purchasers heavily discount the C-rated energy efficiency or question the practical integration of the rear unit.
- The stable, unchanged asking price history since initial listing suggests a confident vendor strategy testing the absolute ceiling of the local market, making final negotiated outcomes heavily dependent on competition among buyers seeking turnkey convenience near Castleknock.
Build Analysis
What we know from similar construction types
- The property is a period semi-detached cottage that has been thoroughly modernised and extended to include a separate self-contained one-bedroom apartment to the rear.
- A buyer should investigate the planning permission and building regulation compliance for the rear self-contained apartment, as well as any sub-division of utilities or services.
- Given its age and period nature combined with modern renovations, a thorough structural survey should be conducted to inspect the interface between the original cottage structure and newer works, as well as damp-proofing and insulation levels.
- The proximity to Phoenix Park and the south-facing orientation are significant positive features, but buyers should check local drainage and potential flood or environmental constraints typical of properties bordering large parks.
