- Underfloor Ground Heating: The ground floor features comfortable radiant heating with multiple independent zones for precise temperature management. This setup enhances interior comfort and maximizes usable wall space by removing traditional radiators.
- Triple Glazed Windows: Premium Alu-clad Rational windows offer superior acoustic insulation and exceptional thermal retention year-round. These durable fixtures protect the interior from external noise while maintaining optimal indoor temperatures effortlessly.
- Original Show House Status: Built as the primary development show house, the property boasts superior finishings and enhanced interior detailing. Buyers benefit from upgraded cosmetic features and immaculate presentation inherited from the original construction phase.
- Solid Brick Facade: The exterior showcases an attractive solid brick finish complemented by durable granite stone surrounds for timeless aesthetic appeal. This traditional construction method ensures low exterior maintenance and long-term structural resilience.
- Luxury German Kitchen: A high-end Burger kitchen is fully equipped with premium quartz worktops and integrated Smeg appliances. This culinary space combines sleek contemporary design with exceptional durability and practical storage solutions for daily use.
- Attic Conversion Permission: Existing planning permission under reference D24B/0345/WEB allows for a straightforward fifth bedroom and en-suite conversion. This adds significant future value and flexible accommodation potential without the planning uncertainty.
- Homebond Latent Insurance: The dwelling benefits from an active 10-year Homebond structural defects insurance policy for added buyer peace of mind. This coverage protects against major unforeseen building flaws originating from the construction process.
- Landscaped Green Setting: The property overlooks a beautifully maintained communal green area, providing a pleasant leafy outlook and safe play space. This scenic position enhances neighbourhood aesthetics and contributes to a peaceful residential atmosphere.
- Wide Rear Garden: The property features a particularly wide private rear garden enclosed by an attractive granite boundary wall. This outdoor space offers ample room for children to play, outdoor dining, and potential future landscaping projects.
- Dedicated Parking Spaces: Two designated car parking facilities are conveniently provided directly associated with the dwelling for resident convenience. These spaces include a modern electric vehicle charging point to support sustainable transportation.
- Generous Floor Area: Measuring approximately 165 square metres, the interior provides well-proportioned rooms and excellent family living flexibility. The balanced layout accommodates modern lifestyles with comfortable bedroom and reception spaces.
- High Ceiling Heights: Elevated ceiling dimensions throughout the ground floor create a remarkably bright and airy atmosphere in living areas. This architectural feature amplifies natural light penetration and enhances the sense of overall spaciousness.
- Premium Sanitary Ware: Bathrooms are fitted with top-quality Roca sanitary ware, combining elegant contemporary styling with robust long-term durability. The inclusion of both baths and separate showers caters effectively to family needs.
- Extensive Wall Panelling: Tasteful decorative wall panelling in the reception hall and living room adds notable character and architectural elegance. This high-end detail elevates the interior aesthetic well beyond standard new-build finishes.
- Wide Plank Flooring: High-quality wide plank oak flooring extends across the ground level, delivering durability alongside sophisticated natural warmth. This robust surface material withstands heavy daily family traffic while remaining easy to clean.
- Dedicated Utility Room: A spacious separate utility area provides practical laundry facilities with stacked appliances and a secondary sink. Direct access to the side passage enhances muddy-boot management and everyday functional efficiency.
- Prime South Dublin Location: Situated in the highly sought-after Mount Merrion neighbourhood, the address commands strong long-term property desirability. Residents enjoy a prestigious suburban address close to established amenities, schools, and parks.
- Exceptional Local Amenities: The property is just a short walk from Deerpark, local shops on The Rise, and Stillorgan village. Quick access to these popular retail and recreational hubs significantly enhances the day-to-day living experience.
But keep in mind:
- High Asking Price: At €1,485,000, the property demands a substantial capital outlay that requires careful comparison against recent local sales. Buyers must verify whether prevailing market values fully support this premium asking price.
- Attic Conversion Costs: While planning permission is granted, the actual build cost to convert the attic space remains unfulfilled. Buyers should budget separately for construction expenses, structural reinforcements, and finishes to realize this potential.
- Management Company Fees: Development schemes with communal landscaped greens often involve annual estate management fees for upkeep. Buyers must investigate potential recurring service charges and confirm what maintenance is covered.
- Maintenance of Granite Walls: The attractive granite boundary walls require occasional specialist cleaning and mortar inspection to prevent weathering damage. Prospective owners should budget for minor exterior masonry upkeep over time.
- Heat Pump Maintenance: Air to water heating systems require regular professional servicing to maintain optimal efficiency and prevent costly mechanical failures. Buyers should inquire about the service history and maintenance contract terms.
- Underfloor Heating Complexity: Sub-floor heating systems can be more complex and costly to repair if subterranean pipe leaks ever occur. A thorough plumbing inspection during the pre-purchase survey is strongly recommended.
- Electric Vehicle Charger: The installed EV charging point should be professionally tested to ensure compatibility with the buyer's specific vehicle model. Upgrades might be necessary depending on the charger's output capacity and age.
- Boundary Line Verification: The exact property boundaries, particularly around the wide rear garden and side passages, should be confirmed via title deeds. Buyers must ensure no discrepancies exist between physical fencing and legal mapping.
- Capped Ceiling Heights Upstairs: While ground floor ceilings are notably high, upper-floor rooms should be checked for standard clearances and furniture fit. Taller buyers should verify headroom in all four upstairs bedrooms.
- Potential Expansion Limits: Although the attic can be converted, future ground-floor extensions might be restricted due to garden footprint limitations. Buyers desiring further extensions should review local planning precedents carefully.
- Traffic Congestion Proximity: Proximity to Trees Road Lower and the N11 quality bus corridor can introduce local rush-hour traffic build-ups. Buyers should evaluate peak-time noise levels and commuting delays during weekdays.
- Lack of Independent Property Type: The listing omits a clear classification of the exact property type, such as semi-detached or end-terrace. Buyers must clarify the structural configuration with the selling agent immediately.
- Homebond Expiry Timeline: Since the property was a show house, the 10-year Homebond insurance clock may have started ticking earlier than standard construction. Buyers need to verify the exact remaining duration of the structural guarantee.
- Window Seal Integrity: Triple glazed Alu-clad Rational windows require periodic inspection of exterior aluminium cladding and seals. Failure to maintain these seals can lead to moisture ingress and compromised thermal performance.
- Landscaped Green Maintenance: Shared landscaped green areas rely on developer or council upkeep to remain attractive and functional over time. Buyers should check who holds ongoing responsibility for the green's maintenance standards.
- Fibre Broadband Verification: While direct fibre connectivity is advertised, buyers should test actual connection speeds and verify available network providers. Remote workers should ensure network reliability meets their professional requirements.
- Storage Limitations Upstairs: Although built-in wardrobes are included in bedrooms, overall standalone storage capacity might be limited without the attic. Families with extensive belongings may find standard bedroom closets restrictive.
- Proximity to UCD Campus: The nearby university campus can introduce student rental dynamics and increased pedestrian traffic during academic terms. Buyers should consider potential rental market saturation if purchasing as an investment.
- BER Verification Due Diligence: The published A2 energy rating must be independently verified against the official BER certificate and energy audit. Buyers should check that no subsequent modifications have altered the home's thermal envelope.
- Future Development Nearby: Remaining plots or nearby infill sites in South County Dublin could face future construction activity and disruption. Buyers should check local development plans for any proposed projects in the immediate vicinity.
Price positioning
?
- The asking price is positioned slightly above recent transactional precedents within the immediate development, where similar high-specification units have achieved recorded figures closely aligned with this target.
- Valuation signals are supported by the property's top-tier A2 energy rating, superior contemporary finishes, and its original show-house status, though these premium attributes are already largely factored into the quoted figure.
- Potential upside is reinforced by existing planning permission for a large attic conversion into an additional bedroom suite, whereas broader macroeconomic shifts or rising interest rates could potentially cap further price appreciation.
- Relevant market dynamics indicate strong ongoing demand for modern, energy-efficient family homes in this exclusive South County Dublin suburb, helping to sustain healthy competitive interest despite the elevated price point.
