  • West-Facing Garden: The rear outdoor space captures ample afternoon and evening sunshine, offering a rare and highly sought-after advantage for a Victorian terrace property.
  • Mature Landscaping: The front and rear gardens feature established plantings, deep borders, and manicured lawns that reflect years of dedicated horticultural care and provide deep privacy.
  • Versatile Double Garage: A substantial garage equipped with a roller shutter and bathroom facilities sits at the rear, offering excellent potential for conversion subject to planning permission.
  • Private Rear Access: The property benefits from a gated rear lane leading to the garage, ensuring convenient and discreet off-street parking or service access.
  • Modern Open-Plan Flow: Former formal interconnecting reception rooms have been thoughtfully transformed into an expansive, light-filled kitchen and dining setup tailored for contemporary lifestyles.
  • Luxurious Main Bathroom: The large return bathroom functions as a private sanctuary featuring a cast-iron claw-foot tub, a feature fireplace, and a gorgeous bay window with shutters.
  • Impressive Drawing Room: Spanning the entire width of the upper level, the principal reception room showcases expansive bay windows framing lovely views across the private park.
  • Versatile Billiards Room: The lower garden level includes a flexible multi-purpose space opening directly onto a private patio area, ideal for entertaining or recreation.
  • Warm Oak Flooring: Beautiful wide-plank oak flooring runs throughout key living areas, adding visual warmth, seamless continuity, and durability to high-traffic zones.
  • Wood-Burning Stove: A recessed wood-burning stove set into the chimney breast of the rear living space provides cozy focal warmth and enhances energy efficiency.
  • Quality Kitchen Integration: The Shaker-style kitchen features durable granite countertops, an island breakfast counter, and integrated appliances designed to accommodate high-end daily cooking.
  • Underfloor Heating: The entire lower garden level is fitted with underfloor heating beneath tiled surfaces, ensuring comfortable temperatures across ground-floor bedrooms and hallways.
  • Excellent School Proximity: Rathdown School is within easy walking distance alongside other reputable educational institutions including The Harold and CBC, benefiting families with children.
  • Convenient Transit Access: The DART is situated within easy walking distance, providing fast and reliable rail connections directly into Dublin city centre and coastal suburbs.
  • Rich Local Amenities: Dún Laoghaire provides an abundance of independent shops, cafes, restaurants, a local cinema, and the Pavilion Theatre right on the doorstep.

  • Vibrant Village Lifestyle: Both Monkstown and Glasthule villages are nearby, offering diverse boutique shopping, gourmet dining, and everyday convenience stores within a short distance.

But keep in mind:

  • Sub-Optimal Energy Rating: The dwelling carries a D2 BER rating, indicating potential thermal inefficiencies that may require capital expenditure on insulation or heating upgrades.
  • Period Maintenance Obligations: Historic architectural elements such as sliding sash windows and ornate cornicing often demand specialized, costly ongoing preservation and upkeep by specialists.
  • Lower Ground Floor Damp Risk: The garden level features tiled flooring and walls integrated into ground-level foundations, which buyers should inspect for potential rising damp issues.
  • Single-Glazed Sash Drafts: While original sliding sash windows are aesthetically pleasing, they may lack modern acoustic and thermal insulation, resulting in drafts and heat loss.
  • Basement Level Bedroom Suitability: Bedrooms located on the lower garden level receive less natural light than upper floors, which may not suit all family members' preferences.
  • Garage Conversion Hurdles: Adapting the rear double garage into a home office or studio is subject to necessary municipal planning permissions and building regulations compliance.
  • Shared Square Maintenance: Buyers should investigate potential annual maintenance fees, covenants, or association rules governing the upkeep of the private four-acre communal park.
  • Protected Structure Status: Prospective buyers must verify whether the property holds protected structure status, which heavily restricts exterior and interior alterations.
  • Staircase Distribution: With accommodation spread across multiple vertical levels including a basement and upper returns, daily living involves navigating numerous flights of stairs.
  • Limited Bathroom Count: Providing three bathrooms across a substantial 310 square meter footprint may require queuing during peak family morning routines, especially with four large bedrooms.
  • Urban Parking Restrictions: While the rear features a garage, on-street parking along Royal Terrace may be subject to local resident permit schemes and visitor limitations.
  • Rear Lane Security: Access via a private gated rear lane introduces security considerations that buyers should evaluate regarding pedestrian and vehicle monitoring.
  • High Heating Volume: Lofty Victorian ceiling heights across principal rooms require greater energy volume to heat effectively during colder winter months.
  • Plumbing and Electrical Age: Buyers should commission a thorough structural survey to determine the age and safety of concealed electrical wiring and domestic plumbing systems.
  • Roof and Gutter Integrity: The expansive roof surface and traditional parapets require regular professional inspection to prevent water ingress and timber rot in upper-floor ceilings.
  • Proximity to Urban Traffic: Dún Laoghaire's bustling commercial center nearby may bring localized traffic congestion and weekend noise to surrounding approach roads.
  • Complex Renovation History: Past alterations connecting rooms and opening returns should be professionally vetted to ensure structural steel lintels were installed to building standards.
  • Garden Drainage Performance: The west-facing multi-tiered garden features lawns and retaining elements that should be checked for proper surface water drainage during heavy rainfall.
  • Fireplace Compliance: Multiple operational open hearths and wood-burning stoves require thorough chimney sweeps and flue certifications to meet current fire safety standards.
  • High Resale Insurance Premiums: Insuring a high-value historic property with specialized period features can incur elevated annual premiums requiring targeted broker quotes.

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 looks moderately overvalued compared with the available evidence.
  • The asking price appears somewhat ambitious at over two point six million euros, given that it sits considerably above local street benchmarks where several substantial terrace properties have historically traded at lower figures.
  • Valuation signals show strength from the expansive three hundred and ten square metre floor area, prime Victorian architecture, private square access, and a highly desirable west facing garden with a large double garage.
  • Upside support for the asking price relies heavily on sustained buyer demand for rare period homes in top south Dublin locations, whereas potential energy efficiency upgrades due to the D2 BER could slightly undermine buyer enthusiasm.
  • Relevant market dynamics indicate that large fully modernised period residences on prestigious private squares command significant premiums, though prospective purchasers will weigh the asking rate against historical capital appreciation trends.

Build Analysis

What we know from similar construction types

  • The property is an exceptional Victorian residence spanning approximately 310 square meters, featuring original period details such as sliding sash windows, high ceilings, intricate cornicing, centre roses, and feature fireplaces combined with modern extensions and alterations.
  • Buyers should investigate the structural integrity of historical modifications, particularly where the return reception room was opened into the hall return and where full-height glazing was added to the rear living space.
  • As a Protected Structure or a home located within an architectural conservation area, any future alterations, external maintenance, or adaptation of the rear double garage into a home office or studio will likely require specific planning permissions and adherence to conservation guidelines.
  • The presence of lower ground floor areas with underfloor heating warrants a thorough inspection for dampness, drainage efficiency, and tanking, which are common considerations in period properties.
  • The BER rating of D2 indicates that the building envelope, original windows, and heating systems allow for significant thermal loss, requiring investigation into energy efficiency upgrades while preserving historic character.

Retrofit Cost*

Possible renovating / insulating expenditure

  • Estimated deep-retrofit cost: €75,000 to €125,000.
  • Reasoning: The property has a BER rating of D2 and a substantial floor area of approximately 310 square meters. Upgrading a large period home of this scale to achieve a B2 rating or higher typically involves external or internal wall insulation (where permissible for protected/historic structures), attic insulation, upgrading or secondary glazing of historic sliding sash windows, installation of a modern renewable heating system such as a heat pump, and airtightness improvements. Conservation constraints on a Victorian facade can significantly increase specialist labor and material costs.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: €3,500 to €4,500.
  • Explanation: Given the D2 energy rating and the substantial 310 square metre floor area of this Victorian residence, thermal efficiency is lower than modern builds, leading to higher heating demands during colder months.

Pollution Safe

9/10

Environmental situation to investigate

  • The property is situated in an established residential suburban area well away from major heavy industrial sites, large-scale incinerators, or active landfills.
  • Any historical urban or coastal industrial legacy in the broader Dún Laoghaire area is distant enough that direct local impact is minimal.

Flood Safe

8/10

Water overflow reports to follow up

  • The elevated topography along Royal Terrace West generally places the location well above immediate coastal flood risks.
  • Standard urban drainage applies during heavy rainfall events, and prospective buyers should verify local drainage and pluvial flood maps for peace of mind.
