Commanding an elevated position on one of Killiney’s most prestigious roads - St. George's Avenue, this exceptional property is on the market for the first time in thirty years, Carrigrenane is a Protected Structure of architectural distinction and historical importance. Set within approximately half an acre of private grounds, this remarkable residence enjoys uninterrupted panoramic views across Killiney Bay towards Bray Head and the Wicklow Mountains, a vista of rare beauty that shifts effortlessly with the light and seasons. Carrigrenane was designed by the eminent Irish Gothic Revival architect George Coppinger Ashlin, who also designed neighbouring St George's House. His father-in-law, Augustus Welby Northmore Pugin - a celebrated architect associated with the design of the Houses of Parliament - brought to Killiney the drama and refinement of the Gothic Revival tradition. The lineage is evident throughout the house in its craftsmanship and attention to detail. Intricate stained-glass windows bear the initials “M&S" commemorating Pugin’s granddaughter Miriam and her husband Stephen, a rare personal signature woven into the architectural fabric of this home. Modern elements were added, including a large balcony, by renowned architect Ross Cahill O’Brien, who described the view as “one of the finest in Killiney”. Extending to approximately 297sqm (3,200sqft), excluding the garage, this residence unfolds with gracious proportions and an atmosphere of quiet grandeur. Many original period details have been carefully preserved, allowing original features to speak with authenticity and elegance. Every room benefits from the home's elevated orientation, with sea and sky forming a constant backdrop. The approach to Carrigrenane is suitably impressive. Automated gates open to a newly gravelled driveway. Steps then descend to expansive gardens, which once boasted a lawn tennis court, offering privacy and space while framing the spectacular coastal panorama. Despite its sense of seclusion, the property is just a short walk from Killiney Beach, providing immediate access to one of Dublin's most cherished stretches of shoreline. Beyond its architectural and aesthetic appeal, Carrigrenane presents significant future potential. Planning permission was previously granted, though now expired, for the conversion of the garage into an independent residence designed by Ross Cahill O'Brien and known as "The Witches Hat" Extension. The proposed dwelling was conceived as a striking contemporary complement to the historic main house. In addition, there remains the possibility of constructing a further residence within the grounds, subject to planning permission, offering flexibility for extended family living or investment.
