- Abundant natural light atrium: An enclosed glass atrium seamlessly connects the solid wood kitchen to the outdoors, flooding the interior spaces with daylight and creating a tranquil transition to the garden.
- Direct street garden access: A secure private side gate provides independent access to the extensive grounds, offering remarkable convenience for landscaping maintenance, deliveries, or alternative entry routes.
- Attached single garage: The inclusion of a garage provides valuable secure off-street parking or additional storage options, which are premium commodities for central period properties in this densely built coastal town.
- Educational options nearby: A strong selection of local preschools, primary schools, and respected secondary institutions are situated within easy reach, making the location highly practical for growing families with children.
- Vibrant local dining scene: The property is a short stroll from popular local cafes, wine bars, and waterfront restaurants, offering an enviable lifestyle with excellent dining and social options right on the doorstep.
- Generous bedroom count: Offering four well-proportioned bedrooms, the house easily accommodates larger family setups or provides dedicated rooms for home offices, hobby spaces, and visiting overnight guests.

- Convenient family bathroom: The ground-floor family bathroom ensures easy accessibility for residents and guests, eliminating the need to climb stairs during daytime routines and general household activities.
- Built-in bedroom storage: Several bedrooms include fitted storage cupboards, helping to maximise floor space and providing ready-made organization solutions for clothing, linens, and personal belongings.
- Maritime tourism proximity: Being located in a renowned coastal hub means residents are close to major visitor attractions, maritime history centres, and scenic coastal walking routes throughout the surrounding harbour area.
- Rare market availability: Properties possessing this specific combination of historic background, extensive gardens, and breathtaking harbour views seldom become available for purchase, representing a distinctive acquisition opportunity.
But keep in mind:
- Subpar energy efficiency rating: The dwelling holds a D energy rating, indicating that prospective buyers should budget for potential insulation upgrades and heating improvements to enhance thermal comfort and reduce utility costs.
- Historic property maintenance demands: As an older period residence, the structure may require ongoing specialist care, damp monitoring, and timber preservation work, meaning buyers should commission a thorough structural survey.
- Single-glazed or older glazing: Due to the historic nature of the building, existing windows may require acoustic and thermal assessment to ensure adequate weatherproofing against coastal winds and winter storms.
- Ground-floor bathroom layout: Having the primary family bathroom located on the ground floor rather than upstairs near the bedrooms may prove inconvenient for night-time routines and multi-occupant households.
- Annex conversion compliance: Transforming the utility and storage wing into a self-contained apartment or granny flat will likely require navigating local planning guidelines and building regulations, adding potential time and expense.
- Steep sloping garden layout: The vast elevated garden may feature sloping terrain that requires careful landscaping management or presents accessibility challenges for elderly residents or young children playing unsupervised.
- On-street parking reliance: While an attached garage is present, overall parking along the central street may be limited during peak times, requiring buyers to verify local parking permits and vehicle storage logistics.
- Dated interior finishes: Certain rooms feature laminate flooring and older decorative styles that some purchasers may wish to modernise, representing an additional financial investment following the initial property acquisition.
- Coastal weather exposure: Positioned directly in a coastal harbour environment, external paintwork, metal fixtures, and roof materials may experience accelerated wear from salt spray and moisture, demanding regular maintenance.
- Restricted single bedroom sizes: Two of the first-floor bedrooms are designated as single rooms with compact proportions, which might limit their long-term flexibility as children grow or if double beds are required.
- Potential plumbing and wiring updates: Given the historic pedigree of the building, buyers should thoroughly inspect the electrical consumer unit and plumbing infrastructure to ensure they meet modern safety standards.
- Limited ground-floor WC privacy: Depending on the exact layout, guests using the ground-floor facilities near the utility wing may pass through primary thoroughfares, impacting overall household privacy.
- Roof and gutter inspections needed: Buyers should engage a professional to inspect the roof valleys, slates, and rainwater goods, as period properties of this scale are prone to hidden leaks during heavy downpours.
- Garden boundary clarity: The extent of the large rear plot should be carefully verified against official title deeds and land registry maps to ensure all boundary lines and access rights are clearly established.
- Ventilation in glass atrium: The enclosed glass atrium may experience significant temperature fluctuations throughout the seasons, requiring a buyer to investigate heating and cooling solutions for comfortable year-round use.
- Foundation and retaining wall check: Given the elevated nature of the rear garden, any retaining structures should be professionally evaluated to ensure long-term structural stability against soil movement.
- Party wall and neighbor considerations: Being situated in a historic terrace or built-up street means future renovation or extension works may involve party wall agreements and close coordination with adjacent properties.
- Accessibility for mobility needs: Multi-level living spaces, steps between zones, and period architectural features could present mobility hurdles for individuals with restricted physical movement without significant alterations.
- Sewer and drainage verification: Older town-centre properties should undergo a comprehensive CCTV drain survey to check for root ingress, pipe calcification, or blockages in the municipal connection lines.
- Heating system efficiency audit: The age and performance of the current boiler and radiator network are unconfirmed, meaning buyers must test the heating infrastructure to avoid unexpected replacement costs after moving in.
Price positioning
?
- The asking price appears slightly below historical benchmarks for similarly proportioned historic residences on the same thoroughfare, suggesting it is competitively positioned given its distinctive architectural heritage and unique maritime setting.
- Signals pointing towards potential under-valuation include the exceptionally large rear garden and panoramic views, though these are offset by a moderate energy rating that may require future capital investment.
- Factors that could support this asking price include high demand for period properties with annex potential, whereas extensive modernization requirements could undermine buyer enthusiasm at this level.
- Overall price-positioning is well-aligned with broader regional transaction trends for substantial character homes, offering a balanced entry point for prospective buyers seeking space and historical charm.
Build Analysis
What we know from similar construction types
- Glenmahon is described as a historic period residence with original features, meaning a buyer should investigate the structural integrity of older building materials, including timber frame elements, roof conditions, and traditional masonry walls.
- Given the property's age and coastal location in Cobh, a thorough survey should check for dampness, rising damp, salt damage, and the condition of rainwater goods and external render.
- The presence of an attached single garage, an enclosed glass atrium, and potential self-contained apartment space means a buyer should verify that any past alterations or extensions comply with local planning permissions and building regulations.
- The property features multiple fireplaces and varying floor finishes; a buyer should verify the safety and operational status of all chimneys and flues.
Retrofit Cost*
Possible renovating / insulating expenditure
- The property has a BER rating of D, indicating that a deep retrofit is worth considering to improve energy efficiency up to a modern B or A standard.
- For a 163 square metre detached or period property with a D rating, a comprehensive deep retrofit involving external or internal wall insulation, upgraded windows and doors, roof insulation, and potentially installing a heat pump or high-efficiency heating system typically ranges between 45,000 and 75,000 euros, depending on the extent of works required and the preservation requirements of a historic structure.
Heating cost*
Estimated expense to heat this property every year
- Estimated annual heating cost: €2,200 to €2,800.
- Explanation: Given the 163 square metre floor area and a BER rating of D, the energy efficiency is lower than modern builds, resulting in higher consumption to heat the historic property adequately throughout the year.
Pollution Safe
8/10Environmental situation to investigate
- The property is situated in an established coastal residential setting in Cobh, appearing generally well removed from major heavy industrial zones, modern large-scale incinerators, or active industrial landfills.
- Given the historic nature of the surrounding port town environment, buyers may wish to verify local environmental reports regarding any minor legacy industrial uses typical of older maritime settlements.
Flood Safe
7/10Water overflow reports to follow up
- The home occupies an elevated position on John O'Connell Street with sweeping views of the harbour, which generally places it well above immediate sea-level flood zones.
- Because the property sits on elevated sloping ground near a coastal harbor town, prospective buyers should review detailed local flood risk mapping to check for any potential surface water runoff or access-route vulnerabilities during extreme weather events.
