But keep in mind:

  • Lack of BER Rating: The property is listed as BER exempt, so the buyer should verify energy efficiency and potential insulation upgrade costs.
  • Period Maintenance Obligations: As a historic early 19th-century residence, ongoing preservation and specialized maintenance of original features may prove costly.
  • Scope for Modernization: While charming, many areas require updating and personalization to match contemporary standards of luxury and interior design.
  • Conservation Restrictions: Due to its architectural heritage and association with William Robertson, local planning controls might limit exterior alterations or extensions.
  • Commercial Viability Uncertainty: Converting the property into a boutique hotel or commercial use requires securing complex planning permissions that are not guaranteed.
  • Carpeted Wet Areas: Some bathrooms and utility areas feature carpet flooring, which may require immediate hygienic replacement with tiles or waterproof materials.
  • Staircase Distribution Challenges: A three-storey layout with multiple split levels and long hallways may impact accessibility for older residents or young children.
  • Basement-Style Tunnel Damp Risk: The unique tunnel entrance and curved subterranean ceiling structures should be thoroughly inspected for potential damp or moisture ingress.
  • Urban Noise Exposure: A central city location overlooking a prominent thoroughfare may experience elevated levels of ambient street and traffic noise.
  • Rear Laneway Security Risks: Relying on a rear roller shutter door for vehicle access necessitates careful evaluation of security measures against break-ins.
  • Oil-Fired Heating Dependency: Dependence on an oil-fired cooker and heating system could expose the buyer to higher and more volatile fossil fuel costs.
  • Complex Roof and Gutter Checks: The expansive historic roof structure and multi-level drainage systems require professional surveying to rule out hidden structural leaks.
  • Single-Glazed Period Windows: Original windows may lack thermal efficiency, meaning the buyer should budget for sensitive secondary glazing or restoration work.
  • Limited Natural Light: Deeper historic floor plans and internal corridors can occasionally restrict direct natural sunlight penetration in central core zones.
  • Boundary Clarification Needed: Legal title due diligence must verify the exact property boundaries and legal rights of way concerning the rear access lane.
  • Plumbing and Electrical Overhaul: Older structures frequently conceal outdated electrical wiring and galvanized pipework that demand comprehensive professional safety testing.
  • Ventilation in Conservatory: The substantial glass conservatory must be checked for proper summer cooling and winter thermal retention performance capabilities.
  • Party Wall Considerations: Being part of a historic urban streetscape, structural repairs or renovations may involve complex party wall agreements with neighbors.
  • High Upfront Capital Outlay: Beyond the purchase price, substantial financial investment will likely be required to fully restore and modernize the 297 square meter floor plan.
  • Uncertainty of Future Local Development: Changes to nearby city zoning or municipal traffic management around William Street could affect long-term residential amenity value.

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 appears broadly in line, with a slight undervaluation signal.
  • The asking price of seven hundred fifty thousand euros for a substantial six bedroom historical property offers a relatively low price per square metre compared to smaller dwellings nearby.
  • Comparable central city properties in Kilkenny demonstrate strong underlying demand, though historical period buildings with extensive floor areas require unique buyer pools.
  • Buyers should investigate potential modernisation and conservation costs carefully, given that the extensive layout and heritage status may entail significant future expenditure.
  • The inclusion of rare city centre private parking for two vehicles significantly enhances the overall value proposition of this historic residential offering.

Build Analysis

What we know from similar construction types

  • The property is a substantial historic three-storey residence built in the early 1800s, designed and formerly lived in by the renowned Kilkenny architect William Robertson, featuring distinct period elements such as original coving, marble fireplaces, bay windows, and a limestone entrance porch.
  • Given its age and historical status, a buyer should investigate the structural integrity of older elements, including the unique curved ceiling design over the tunnel entrance, timber framing, roof condition, and damp management across multiple levels.
  • As the property is a historic building with original architectural features, a buyer should verify its status on the National Inventory of Architectural Heritage (NIAH) or local protected structures records, which may impose restrictions on future modernization, alterations, or commercial uses.
  • The listing notes the property is BER Exempt, which is common for protected historic structures, but a buyer should look into energy efficiency improvements like secondary glazing, insulation, and heating optimization that comply with conservation guidelines.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost ranges between €3,000 and €4,500.
  • Explanation: Given the large 297 m² three-storey floor area, high ceilings typical of period architecture, and the reliance on an oil-fired Stanley cooker and gas fires (with the BER rating noted as exempt/not provided), energy consumption is expected to be substantial compared to a modern standard home. Actual costs will heavily depend on thermal upgrades, insulation measures, and individual lifestyle usage.

Pollution Safe

8/10

Environmental situation to investigate

  • The property is located in an established urban centre with typical urban air quality influences from traffic, though no major heavy industrial pollution sources or large-scale active landfills are immediately adjacent.
  • As a historic city centre building dating to the early 19th century, buyers should investigate potential legacy environmental concerns typical of older urban cores, such as historical fuel storage or lead piping, during a standard structural survey.

Flood Safe

7/10

Water overflow reports to follow up

  • While general flood risk maps for Kilkenny city indicate managed defenses along the nearby River Nore, low-lying parts of the urban center have experienced historical fluvial or pluvial caution events.
  • Buyers are advised to verify the specific local drainage and site-specific flood history with the local authority or through a detailed environmental flood report.
