What you'll like:
- Stunning Waterfront Location: The properties occupy an exceptional coastal setting directly facing Dublin Bay, providing dramatic, uninterrupted sea views that enhance long-term lifestyle appeal and asset value.
- Dual Period Homes: Offering two substantial Victorian-era buildings c.1860s in one offering provides remarkable flexibility for multi-generational living, rental income generation, or corporate headquarters use.
- Substantial Floor Area: Together encompassing approximately 550 square meters of accommodation, these spacious structures offer immense room for bespoke architectural reconfiguration and luxury finishes.
- Residential Planning Secured: Both buildings successfully benefit from full residential planning permission, removing the significant regulatory hurdles usually associated with converting commercial spaces back to homes.
- Flexible Purchase Lots: Available to buy as a single grand compound or in two separate lots, allowing buyers to tailor the acquisition to their specific financial and spatial requirements.
- Immaculate Upgraded Condition: Extensively upgraded and meticulously maintained by the current owner, both buildings present in excellent decorative order throughout, minimizing immediate pre-move-in capital expenditure requirements.
- Original Architectural Details: Retains numerous authentic period features including ceiling cornicing, center roses, operational window shutters, and period fireplaces that preserve historic character and elegance.
- Secure Off-Street Parking: A generous rear parking area accessed via secure electric gates solves a major practical challenge for coastal properties lacking standard street-level garage facilities.
- Favorable Rear Orientation: The rear yard and car park enjoy a bright south-west aspect, capturing afternoon and evening sun for potential landscaped garden conversions.
- Desirable Coastal Neighborhood: Nestled in the heart of Sandycove near Glasthule and Dun Laoghaire, residents gain immediate access to upscale boutiques, award-winning restaurants, and gourmet food emporiums.
- Unmatched Swimming Access: Sea swimmers will deeply appreciate the exceptionally close proximity to Scotsman's Bay and the iconic Forty Foot traditional bathing area just minutes away.
- Active Lifestyle Proximity: The coastal walking and cycling route running directly in front of the property links Dun Laoghaire's East Pier and the Forty Foot for breathtaking recreation.
- Elite Sailing Facilities: Close proximity to the four renowned yacht clubs of Dun Laoghaire makes this an ideal purchase for sailing enthusiasts and marine sports participants.
- Exceptional Public Transit: The nearby DART station at Sandycove and Glasthule alongside frequent bus routes ensures swift, convenient, and reliable public transportation into Dublin city center.
- Renowned Educational Institutions: Highly regarded local schools including Castle Park School, Loreto Dalkey, and Blackrock College sit within easy commuting distance for families.
- Future Development Potential: The combined footprint offers exciting future development or extension opportunities, subject to acquiring the appropriate local authority planning approvals.
- Commercial Use History: Having been used as high-end offices, the layout includes robust network cabling, ample WCs, and versatile rooms easily adapted for modern remote-working lifestyles.
- Stable Asking Price: The recorded asking price has remained completely unchanged at €4,250,000 without erratic fluctuations, suggesting a confident seller or realistic initial valuation strategy.
- Dual Street Access: Featuring separate pedestrian and vehicular access points from both front and rear boundaries optimizes privacy, service logistics, and daily movement flow.
- Energy-Conscious Upgrades: Fitted with double-glazed sash windows and modern gas-fired central heating, successfully blending historic aesthetic requirements with improved thermal efficiency.
But keep in mind:
- Low BER Rating: The property carries a poor E energy rating, which will necessitate substantial insulation and heating system upgrades to achieve modern energy efficiency standards.
- Commercial Transition Costs: While residential planning is secured, buyers should budget for internal adaptations—such as kitchen installations and bathroom reconfiguration—to convert office spaces back into comfortable homes.
- Substantial Capital Outlay: The multi-million-euro asking price of €4,250,000 limits the pool of prospective buyers and requires significant liquidity or complex financing structures.
- Conservation Restrictions: Given the historic Victorian period nature of the structures, strict local conservation guidelines may limit the scope and style of future exterior modifications.
- Shared Access Lane: The rear vehicular access is shared via a side lane servicing multiple properties, which could occasionally lead to logistical friction or maintenance disputes.
- Uncertain Development Approval: While future development potential is mentioned, buyers must verify local planning precedent to ensure ambitious extension or subdivision plans will be approved.
- High Maintenance Liabilities: Maintaining two large nineteenth-century buildings with extensive square footage will entail higher-than-average ongoing property upkeep and specialized repair costs.
- Parking Versus Garden Trade-off: The rear south-west courtyard is currently laid out entirely as parking, meaning a buyer must invest additional capital if they wish to convert it back into green space.
- Potential Layout Complications: The commercial layout features numerous interconnecting rooms that may require structural wall alterations to create a more traditional, fluid residential family flow.
- Stagnant Price Indicator: The lack of price movement since initial listing tracking began could reflect an inflexible vendor or a property testing the absolute ceiling of the local market.
- Complex Utility Infrastructure: Merging or separating utility meters, fire safety systems, and commercial-grade amenities back into domestic configurations could involve unexpected municipal expenses.
- Coastal Weather Exposure: Direct waterfront exposure to Dublin Bay means salt spray and high winds will accelerate exterior weathering, requiring frequent painting and masonry maintenance.
- Basement Damp Risk: The garden-level subterranean rooms in period properties frequently require professional damp-proofing assessments and ongoing ventilation management to prevent moisture ingress.
- Limited Bathroom-to-Bedroom Ratio: Buyers should carefully audit the existing number of functional showers and baths relative to the large overall footprint to determine if additions are needed.
- Acoustic Privacy Challenges: Properties situated directly along a popular coastal walking, cycling, and traffic route may experience elevated ambient noise levels during peak recreational weekends.
- Lack of Exact Room Counts: Official listing details omit precise bedroom and bathroom counts, requiring a meticulous physical walkthrough to verify exact functional capacities.
- Staged Sale Complexities: Offering the properties in one or two lots introduces potential negotiation and closing complexities if multiple competing parties emerge for split portions.
- Historic Plumbing Conditions: Older pipework associated with the building's commercial past should be thoroughly inspected by a certified plumber to rule out hidden corrosion or inadequate capacity.
- Roof and Gutter Integrity: Inspecting the expansive multi-pitched roofs of two large period structures is critical to identify potential slate damage, dry rot, or failing guttering systems.
- Future Zoning Vulnerabilities: Buyers should verify current local development plans to ensure no future municipal coastal protection or public amenity projects might adversely affect the boundary.
Price positioning
?
- The asking price appears somewhat elevated relative to baseline regional benchmarks when considering the substantial overall quantum, reflecting the prime waterfront location and combined scale of two large properties.
- Valuation signals are driven by the rare opportunity to acquire a substantial dual-property holding with full residential planning permission, though the poor energy rating and previous commercial use require capital expenditure.
- Support for this price point relies heavily on sustained luxury buyer demand for coastal trophy assets, while potential economic headwinds or high renovation costs could undermine achievable market values.
- Additional relevance stems from the flexibility of purchasing in one or two lots, offering potential future development upside that could attract institutional or high-net-worth investors looking for prime repositioning opportunities.
Build Analysis
What we know from similar construction types
- The property comprises two substantial Victorian period buildings dating from the 1860s, operating most recently as commercial offices with full residential planning permission for reversion back to single or dual homes.
- A buyer should verify the compliance and condition of previous commercial alterations, including fire safety measures, partitions, and accessibility features, to ensure they align with residential building regulations.
- Given the waterfront location facing Dublin Bay, a thorough structural and damp survey should be conducted to assess potential exposure to coastal weathering, salt air degradation, and dampness in the basement levels.
- The combined floor area is substantial (approximately 714 square meters across both lots), meaning any future reconfiguration, modernization, or development works should be verified for local planning constraints and protected structure guidelines.
Retrofit Cost*
Possible renovating / insulating expenditure
- The properties currently carry an E BER rating, which reflects the energy inefficiency typical of uninsulated 19th-century period buildings.
- A comprehensive deep retrofit for approximately 700+ square meters of protected-structure period property—including sensitive internal or external wall insulation (where permitted), roof insulation, window upgrades, and modern heating systems—would likely be very substantial.
- Estimated deep retrofit costs could easily range from €150,000 to €250,000 or more, depending on the extent of conservation-grade works required and the chosen mechanical and electrical upgrades.
Heating cost*
Estimated expense to heat this property every year
- Estimated annual heating cost: 6,000 to 9,000 euro.
- Explanation: With a very large combined floor area of approximately 550 square metres and a low BER rating of E, thermal efficiency is poor, leading to significantly higher energy consumption for gas-fired central heating.
Pollution Safe
9/10Environmental situation to investigate
- The location is in a long-established residential and coastal suburb with minimal heavy industrial presence nearby.
- Any historical urban or commercial use on or around the site would be typical of a built-up coastal town environment, with no major known regional landfill or severe legacy contamination concerns directly affecting the immediate immediate vicinity.
Flood Safe
7/10Water overflow reports to follow up
- The property occupies a prominent seafront location facing Dublin Bay, placing it close to coastal hazard zones where extreme sea levels and storm surges are relevant considerations.
- National coastal mapping places a mapped flood zone in close proximity to the site, indicating that low-lying marine elements or adjacent coastal paths could experience inundation during severe weather events.
- The inclusion of lower garden levels and basement areas means that any localized pooling or extreme coastal weather could present practical management considerations for lower points of the structure.
The property is outside the mapped flood area. But the nearest mapped area is approximately 55 metres away. This map does not account for flood defences.
