What you'll like:
- Extraordinary garden length: The property boasts a massive forty-meter rear garden, offering rare outdoor space for a suburban location that will delight families and avid gardeners.
- Dual accommodation setup: Substantially extended to form two separate two-storey houses, providing an exceptional setup for extended family living or potential rental income streams.
- Quiet cul-de-sac position: Situated in a peaceful cul-de-sac towards the rear of a mature estate, minimizing through traffic and enhancing residential peace and privacy.
- Proximity to Luas: Located within easy reach of the Windy Arbour Luas stop, ensuring fast and convenient public transport access directly into Dublin city center.
- Proximity to shopping: Close to the renowned Dundrum Town Centre, giving residents immediate access to premier retail, dining, cinema, and entertainment amenities nearby.
- Educational access: Positioned within convenient reach of University College Dublin alongside a strong selection of established local primary and secondary schools.
- Off-street parking: Features a generous low-maintenance front driveway with ample private parking space for multiple vehicles off the main public road.
- Versatile configuration potential: Offers obvious potential to reinstate the footprint back into one substantial family residence, subject to obtaining necessary building and planning permissions.
- Independent side access: The rear house benefits from independent side entry access, ensuring privacy and separation between the two distinct living units.
- Mature neighborhood setting: Nestled in a highly sought-after and established South Dublin residential enclave known for long-term neighborhood stability and community appeal.
- Sunroom addition: The rear dwelling includes a bright sunroom enjoying direct access and pleasant green views over the expansive back garden space.
- Multiple reception spaces: Provides multiple distinct living and family rooms across both dwellings, accommodating flexible daily routines and multi-generational households comfortably.
- Two functional kitchens: Equipped with two separate kitchen areas, allowing independent meal preparation for two households without sharing living quarters.
- Multiple bathroom facilities: Includes multiple bathrooms across the layout, reducing morning congestion and enhancing convenience for larger or multi-family occupants.
- Strong rental appeal: The dual-dwelling layout presents intriguing investment potential for buyers looking to generate auxiliary income through independent letting arrangements.
- Generous footprint: Offering substantial total floor area split efficiently across two structures, providing comfortable room proportions for modern family lifestyles.
- Green outdoor potential: The massive garden creates a wonderful canvas for landscaping, outdoor entertaining areas, garden rooms, or future home extensions.
- Proximity to villages: Conveniently close to local neighborhood shops and charming villages like Clonskeagh and Milltown for everyday conveniences and cafes.
- Natural light intake: Well-proportioned rooms with multiple windows capture good natural daylight throughout various times of the day across both structures.
- Established services: Connected to established neighborhood infrastructure including mains gas-fired central heating and municipal utility networks ready for ongoing use.
But keep in mind:
- Extremely poor BER rating: Both dwellings carry a disappointing G energy rating, indicating severe thermal inefficiency and requiring urgent, costly fabric upgrades.
- High retrofit costs: Achieving modern energy efficiency standards will demand significant capital expenditure on insulation, heating upgrades, and window replacements throughout.
- Planning permission complexities: Reinstating the two dwellings back into a single family home will require navigating complex local planning regulations and associated architectural expenses.
- Legal title verification: Buyers must verify that the structural extension and dual-occupancy setup possess full and compliant planning history and building control certification.
- Outdated interior finishes: The internal spaces show dated decorative finishes that will require comprehensive modernization and refurbishment prior to comfortable occupation.
- Suboptimal room proportions: Certain bedrooms and kitchen areas within the rear dwelling are relatively compact, which may feel restrictive for long-term family living.
- Dual utility management: Managing two separate housing units under one title may complicate utility billing, insurance arrangements, and council tax or property tax classifications.
- Potential structural alterations: Unifying the two houses back into one layout will involve substantial structural engineering work, knocking through walls, and reconfiguring plumbing.
- Upgrading heating systems: The existing gas-fired central heating systems should be professionally inspected to determine if they require total replacement to meet modern demands.
- Roof and insulation check: The age and condition of the roofs across the extended structure require thorough independent surveying to identify any hidden moisture or timber decay.
- Plumbing and electrical audit: Independent specialists must thoroughly test the dual kitchens, bathrooms, and electrical fuse boards to ensure compliance with current safety standards.
- Garden maintenance workload: While the forty-meter garden is an asset, its sheer size will demand substantial ongoing landscaping and maintenance effort from the homeowner.
- Potential damp issues: Given the G energy rating and age of extensions, buyers should investigate potential damp ingress and ventilation adequacy in older sections.
- Boundary line verification: Buyers should have their legal representatives carefully inspect title maps to confirm the exact boundaries of the exceptionally long rear garden.
- Party wall considerations: If the property shares structural ties with neighbors in the cul-de-sac, party wall agreements should be reviewed during future renovations.
- Potential fire safety upgrades: Converting or maintaining a dual-occupancy building may require specialized fire-rated doors and separation walls to satisfy building regulations.
- Renovation disruption: Undertaking the necessary remodeling to modernize or unify the property will cause significant short-term living disruption and contractor management overhead.
- Local parking limitations: While a front driveway exists, the cul-de-sac setting might experience visitor parking congestion during peak school or evening hours.
- Soundproofing deficiencies: Depending on how the extension was joined, sound insulation between the two independent houses may be inadequate and require remediation.
- Future resale liquidity: The niche nature of a dual-dwelling suburban home might appeal to a more specialized buyer pool compared to standard single-family houses.
Price positioning
?
- The asking price appears somewhat elevated relative to recent local transactions, likely driven by the unique configuration of two independent living units within a single footprint.
- Upward valuation signals stem from the exceptionally long garden, off-street parking, and proximity to transport links, whereas the very poor energy rating presents a clear downward signal.
- Market support for this pricing relies on strong investor or multi-generational family demand, though substantial required retrofit expenditures could undermine the viability of the quoted figure.
- Relevant considerations include potential future planning constraints or heavy capital outlays necessary to modernize the layout or unify the structure back into a single family home.
Build Analysis
What we know from similar construction types
- The property has been substantially extended and divided into two separate two-storey houses under one roof, which may have implications for regulatory compliance, fire safety between units, and utility metering. A buyer should verify planning permission and building control compliance for the extension and subdivision.
- There is potential to reinstate the property as a single large family home, though this would require reconfiguration, removal of partition walls or secondary kitchens, and associated costs.
- The BER rating is G for both units, indicating very poor thermal performance, likely due to a lack of adequate wall, roof, and floor insulation, as well as inefficient glazing and heating systems.
- A buyer should investigate the condition of the roof, plumbing, and electrical systems across both sections of the property, given the age of the mature estate and the dual-occupancy layout.
Retrofit Cost*
Possible renovating / insulating expenditure
- Given the G BER rating and a floor area of approximately 125 m2, a deep retrofit to bring the property to a modern B2 or A rating is estimated to cost between 60,000 and 90,000 euros.
- This work would likely require external or internal wall insulation, attic insulation, upgrading all windows and exterior doors to high-performance double or triple glazing, replacing the heating systems with a heat pump or modern condensing boiler, and addressing airtightness and ventilation.
Heating cost*
Estimated expense to heat this property every year
- Estimated annual heating cost: approximately 3,000 to 4,000 euro.
- Explanation: Given the poor G energy rating and the extended layout comprising two separate dwellings of approximately 125 square metres total floor area, energy efficiency is very low, resulting in significantly higher heating demands compared to modern or well-insulated homes.
Pollution Safe
9/10Environmental situation to investigate
- The location is situated in a well-established residential suburb with no apparent major industrial facilities, heavy manufacturing, or active large-scale landfills in immediate proximity.
- As with many urban and suburban areas, buyers should verify local historical land uses for any legacy commercial or waste disposal sites during their standard due diligence.
Flood Safe
8/10Water overflow reports to follow up
- The property is located in an established suburban setting well away from major coastal flood zones, though localized pooling during extreme weather events should always be checked.
- Prospective buyers are advised to consult local authority flood maps and environmental reports to confirm the specific flood risk profile of the immediate plot.
