But keep in mind:
- Sub-Optimal BER Rating: A C1 energy rating for a property at this price point may require considerable capital investment in deep retrofitting to improve thermal efficiency.
- High Capital Threshold: An asking price close to five million euros narrows the prospective buyer pool and demands rigorous liquidity or financing verification.
- Historic Preservation Constraints: Period features and architectural protections could restrict future modernization, external modifications, or energy efficiency upgrades a buyer might desire.
- Potential Retrofit Costs: Bringing a large Victorian-era footprint up to modern A-rated energy standards could entail significant disruption and unexpected construction expenses.
- Maintenance of Grounds: Managing 0.30 acres of mature gardens, extensive lawns, and complex planting schemes may require ongoing professional landscaping services and costs.
- Traffic and Parking Congestion: Popular coastal suburbs can experience localized traffic congestion during peak commuting and fine weekend weather periods near DART stations.
- Window Restoration Needs: Original sliding sash windows, while aesthetically pleasing, should be inspected for drafts, rot, and thermal performance inefficiencies typical of older timber frames.
- Roof and Structure Diligence: Buyers should commission a thorough structural survey to inspect the older roof timbers, valleys, and hidden junctions where original structure meets new extensions.
- Plumbing Infrastructure Age: The integration of new high-capacity bathrooms and wet rooms with older legacy plumbing risers warrants careful engineering and pressure testing.
- Drainage System Capacity: An expanded footprint and increased sanitary fixtures mean the underlying storm and foul water drainage systems should be professionally surveyed.
- Electrical System Upgrades: While partially upgraded during recent renovations, the entire electrical distribution board and wiring runs should be certified to modern standards.
- Heating Zone Control: Heating a footprint of over 5,000 square feet efficiently requires advanced multi-zone thermostatic controls to prevent excessive energy consumption.
- Potential Sound Transmission: Open-plan ground floor layouts, while modern and desirable, can sometimes lead to acoustic reverberation and reduced sound privacy between zones.
- Boundary Demarcation Check: Buyers should verify exact legal boundaries and title maps for the 0.30-acre plot to ensure all garden spaces and access points are fully clear.
- Local Planning Restrictions: Being situated in a desirable residential zone may mean strict local planning policies apply to any future garden structures or extensions.
- High Property Transaction Costs: Stamp duty and associated legal fees on a multi-million-euro purchase represent a substantial additional upfront capital requirement.
- Basement or Sub-Grade Risk: Due to the age of the structure, buyers should check for any dampness issues in lower-level utility zones or return sections.
- Ventilation in En-Suites: Interior en-suite bathrooms rely heavily on mechanical extraction, which should be inspected for adequate airflow to prevent moisture buildup.
- Insurance Premiums: Insuring a large period home with high-value finishes and historical architectural elements may carry higher than average annual policy costs.
- Future Resale Liquidity: Ultra-prime properties can experience longer selling cycles during broader economic shifts, impacting short-term liquidity if an urgent sale is needed.
Price positioning
?
- The asking price appears somewhat aligned with recent market positioning and underlying valuation metrics for a large, upgraded residence in this prestigious coastal suburb, suggesting the current figure is closely reflective of its extensive floor area and premium location.
- Valuation signals indicate strong support derived from the comprehensive architectural redesign, substantial square footage exceeding five thousand square feet, and premium amenities like a south-facing garden situated on an attractive plot.
- Factors that could support such a price include the scarcity of large, fully modernized period properties with high energy ratings close to DART services, while potential oversupply of luxury units could mildly undermine aggressive pricing growth.
- Relevant market dynamics encompass stable buyer demand within South Dublin coastal locations, alongside the distinct scale of the dwelling compared to neighboring properties that generally trade at lower overall price points.
Build Analysis
What we know from similar construction types
- The property is a substantial Victorian residence extending to over 5,000 sq.ft. (approx. 473.6 m²), comprehensively reimagined, upgraded, and extended under the guidance of architect Paul Brazil.
- Buyers should investigate the integration of the modern rear extension with the original period structure, checking for any potential structural movement, dampness, or issues around roof junctions and lightwells.
- Verify the compliance and planning permission of all structural alterations, extensions, and the garage/plant room conversion.
- Inspect the condition of original features such as sliding sash windows, fireplaces, and intricate ceiling plasterwork for any hidden deterioration or maintenance requirements.
- Given the scale of the property, a thorough survey of the mechanical and electrical systems, plumbing, heating, and the integrated plant room should be conducted.
Heating cost*
Estimated expense to heat this property every year
- Estimated annual heating cost: €3,500 to €5,000.
- Explanation: With a floor area exceeding 5,000 sq.ft. (approx. 473 m²) and a C1 BER rating, the property has a significant volume to heat. While upgraded with modern touches and a woodburning stove, the scale of this large Victorian home will result in notably high energy consumption during colder months.

9/10Environmental situation to investigate
- The location is situated in an established, low-density coastal residential suburb well away from heavy industrial zones, major waste facilities, or active landfills.

Flood Safe
9/10Water overflow reports to follow up
- The property is located in Glenageary, a well-established residential suburb in South Dublin with generally favorable topography well above typical coastal or river flood levels.
- Deterministic mapping indicates no nearby mapped flood zones affecting the immediate site, suggesting a low apparent exposure to fluvial or coastal flooding.
