What you'll like:

  • Generous Floor Area: Spanning approximately 156 square meters across three storeys, this spacious home provides exceptional room for growing families seeking comfortable suburban living. This generous layout ensures ample space for versatile daily routines and long-term accommodation needs.
  • Rare Property Style: As one of only four family homes of this specific style within the development, this residence offers distinct architectural exclusivity. Such scarcity often preserves strong future resale value and community appeal.
  • Quiet Enclave Setting: Positioned as the second house from the end of a quiet cul-de-sac enclave, the property enjoys minimal passing traffic. This peaceful positioning enhances everyday privacy and creates a safer environment for children.
  • Energy Efficiency Rating: Boasting an impressive C1 energy rating, the property benefits from modern construction standards that promote lower utility bills. Buyers should verify if minor upgrades could easily push this rating into an even higher bracket for green mortgages.
  • Modern Construction Era: Built around 2018 by established developers, the property benefits from contemporary building regulations, modern wiring, and plumbing standards. This recent construction date minimizes immediate maintenance concerns and costly structural repairs for the buyer.
  • Open Plan Living: The seamless flow between the kitchen and dining area creates a wonderful hub for modern family interaction and entertaining. Double patio doors extend this living space directly into the rear garden during warmer months.
  • High-End Kitchen Finishes: The fitted Nolan kitchen comes complete with premium Quartz countertops and integrated high-quality appliances. These durable, stylish surfaces offer both aesthetic appeal and long-lasting functionality for daily culinary tasks.
  • Sealed Wood-Burning Fireplace: The living room features a sophisticated La Martine sealed wood-burning fireplace that adds cozy warmth and a striking focal point. This premium feature enhances the room's ambiance during colder winter evenings.
  • Four Contemporary Bathrooms: Featuring a guest toilet, a family bathroom, and two en-suite shower rooms, morning congestion is virtually eliminated for busy households. All bathrooms are finished to a contemporary standard with modern sanitary ware.
  • Palatial Master Suite: Occupying the entire second floor, the expansive master bedroom includes a dedicated walk-in wardrobe and an adjoining private en-suite. This luxurious setup provides parents with a private retreat away from the main bedrooms.
  • Dedicated Home Office: The upper level includes a separate study illuminated by a Velux window, making it ideal for remote working or studying. This dedicated workspace supports productive habits without sacrificing any bedroom space.
  • Ample Fitted Storage: Extensive fitted wardrobes by Cawleys are installed across multiple bedrooms, offering organized storage solutions right from move-in day. Additional under-stairs storage maximizes every square inch of the interior layout.
  • Charming Wall Paneling: Tasteful decorative wall paneling adorns the entrance hallway, stairs, and landings, adding a touch of sophisticated character. This classic detail elevates the interior aesthetic well beyond standard builder finishes.
  • Solar Thermal Integration: Equipped with solar thermal panels and a heat recovery ventilation system, the home maintains fresh air circulation while cutting energy costs. These eco-friendly systems contribute significantly to sustainable, comfortable modern living.
  • Secure Parking Facilities: A private paved driveway provides convenient off-street parking space for up to two vehicles directly at the front of the house. This private parking setup adds everyday convenience and security for vehicle owners.
  • Southeast Garden Aspect: The approximately 10-meter rear garden benefits from a highly desirable southeast orientation, maximizing natural morning and midday sunlight. Paved patio areas and perimeter fencing make it ready for outdoor dining and relaxation.
  • External Garden Conveniences: The enclosed back garden features a practical storage shed and an external power point for gardening or leisure appliances. These thoughtful additions make outdoor maintenance and entertaining significantly easier.
  • Unrivaled Transport Access: Positioned just minutes from multiple train stations and frequent bus routes including the 37 and 70D, commuting is exceptionally straightforward. Rapid access to the N3, M3, and M50 further simplifies travel across Dublin.
  • Proximity to Phoenix Park: The development sits just a stone's throw from the scenic Phoenix Park, offering endless green space for recreation and weekend walks. This renowned amenity drastically enhances the lifestyle quality for local residents.
  • Walkable Local Village: Castleknock Village is within comfortable walking distance, providing a rich selection of shops, dining, and essential local services. This convenience reduces reliance on cars for everyday errands and social activities.

But keep in mind:

  • Three-Storey Layout: The vertical distribution across three floors means frequent stair climbing throughout the day, which may not suit all mobility preferences. Buyers should consider how this layout fits their long-term physical accessibility needs.
  • School Catchment Verification: While the property is noted as being in the catchment for certain local schools, admission policies frequently change and competition is notoriously high. Buyers must independently verify current enrollment criteria directly with the relevant school boards.
  • BER Discrepancy Note: The listing text mentions an A3 rating while the primary facts state C1, representing a significant variance in energy efficiency. Buyers should carefully inspect the official BER certificate to confirm the exact energy performance rating.
  • Enclave Management Fees: Living within a modern managed development often entails annual estate or management fees for common areas and landscaping upkeep. Buyers must verify the existence of any such fees and review past financial statements.
  • Compact Rear Garden: Measuring approximately 10 meters in length, the southeast-facing rear garden is relatively compact for a four-bedroom family home. Those desiring expansive lawns or substantial outdoor expansion room may find this space limited.
  • High-Density Neighborhood: The immediate Fairhaven development features relatively close-set semi-detached homes, which may slightly impact direct line-of-sight privacy from neighboring windows. Buyers should assess overlooking angles from adjacent properties during viewing.
  • Stairs Safety for Toddlers: With bedrooms spread across upper levels and the master suite on the top floor, families with very young children should assess child-safety gate requirements. Navigating multiple flights of stairs at night can occasionally prove challenging.
  • Second Floor Eaves Space: The top-floor master suite and office may experience unique thermal dynamics or restricted ceiling heights typical of attic conversions. Buyers should inspect the roof insulation and check for any potential restricted headroom zones.
  • Maintenance of Solar Systems: Specialized eco-technologies like solar thermal panels and heat recovery ventilation require periodic professional servicing to maintain optimal efficiency. Buyers should factor potential specialist maintenance costs into their long-term budgeting.
  • Traffic Congestion Points: Proximity to major commuter arteries like the N3 and M50 can lead to localized rush-hour traffic congestion near the development entrance. Buyers should test peak-hour commute times to gauge realistic travel delays.
  • Cawleys Wardrobe Durability: While fitted wardrobes by Cawleys offer stylish storage, buyers should inspect the hinges, sliding mechanisms, and interior finishes for wear. Upgrading or replacing custom built-ins can involve notable carpentry expenses if damaged.
  • Quartz Countertop Sealing: The high-end Nolan kitchen features Quartz countertops which, while durable, require specific cleaning agents to prevent chemical staining. Buyers should confirm proper care guidelines to maintain the pristine stone finish over time.
  • Boundary Fence Responsibility: The timber fencing outlining the perimeter of the rear garden will require ongoing maintenance, staining, or eventual replacement. Buyers should clarify whether boundary upkeep falls to individual homeowners or the estate management.
  • External Electrical Safety: The inclusion of an external power point in the back garden is convenient, but buyers should ensure it meets current outdoor waterproofing standards. An electrical survey should verify that exterior circuits are properly RCD protected.
  • Velux Window Seals: The home office features a Velux window in the roofline, which is susceptible to weather wear and potential seal degradation over time. Checking for any historical moisture stains around roof windows during inspection is strongly recommended.
  • Pump Pressure Shower Checks: Both en-suites utilize pump pressure showers, which rely on mechanical pumps that can generate operational noise or require eventual replacement. Buyers should test water pressure and listen for unusual motor sounds during viewings.
  • Chain Free Status Verification: The listing notes a chain-free sale, but property transactions can encounter unexpected legal delays during contract exchange. Buyers should have their legal representatives independently confirm the vendor's actual readiness to proceed.
  • Proximity to Train Lines: Depending on the exact micro-location within Castleknock, nearby commuter train lines might generate intermittent ambient noise. Buyers should visit the property at different times of day to gauge environmental noise levels accurately.
  • Limited Attic Storage: Because the second floor utilizes the attic space for a master suite and study, traditional cold-water tank or seasonal storage loft space may be restricted. Buyers with large volumes of bulky seasonal items should inspect alternative storage options.
  • Automobile Reliance for Errands: Although village amenities are walkable, daily life in outer Dublin suburbs often still requires heavy reliance on personal vehicles. Buyers should evaluate whether local public transit options fully satisfy their specific weekly transit habits.

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 of €825,000 appears slightly below recent local evidence, notably compared to a verified sale of a similar property on the same street achieving €840,000 in late 2025.
  • Valuation signals indicate good value given the high specification, modern build year of 2018, substantial floor area, and energy efficiency features which typically attract strong buyer competition in this prime Dublin 15 location.
  • Potential factors supporting this pricing include high demand for turnkey family homes near Phoenix Park, while downside risks are minimal given the scarcity of this specific four-bedroom three-storey style within the development.
  • Overall, the property presents a compelling entry point relative to recent direct comparables on the same development, positioning the asking price as attractive and potentially conservative for the prevailing market conditions.

Build Analysis

What we know from similar construction types

  • The property is a three-storey semi-detached home built c. 2018 by Flynn & O'Flaherty, offering a modern construction standard with features such as double-glazed windows, brick and render exterior finishes, and granite cills.
  • Listing details claim an 'A3' energy rating and mention solar thermal panels along with a heat recovery ventilation system, though the BER rating is separately noted as C1 in the structured fields, so a buyer should verify the official BER certificate and green mortgage eligibility.
  • The layout spans 156 square meters across three levels, incorporating four bedrooms, four bathrooms, a walk-in wardrobe, and a top-floor study, which requires checking compliance and planning permission for the conversion of the second floor if applicable.
  • Modern internal fittings include a Nolan fitted kitchen with Quartz countertops and Cawleys fitted wardrobes, but a buyer should inspect the condition of integrated appliances and ventilation units during a structural survey.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: approximately 1,000 to 1,400 euro.
  • Explanation: Based on the 156 square metre floor area and energy-efficient construction, heating and hot water demands are expected to be moderate, though actual costs will vary depending on household usage habits.
