The Paddock is a rare architectural treasure and an extraordinary opportunity to thoughtfully restore a true piece of Pittsburgh history. It is the only remaining Sewickley Heights residence designed by Alden & Harlow, the renowned architects behind the Carnegie Library of Pittsburgh and the Duquesne Club.
Commissioned by Adelaide Burguinn, this estate was built with enduring quality, proportion, and craftsmanship that simply cannot be replicated today. Behind its stately presence lies the chance to steward a landmark property and shape its next chapter with vision and intention.
Set privately on expansive manicured grounds in Sewickley Heights, the property offers sweeping lawns, a paddock, kennel, and mature trees that create natural privacy while remaining minutes from Sewickley Village, Quaker Valley Schools, and Downtown Pittsburgh.
Inside, more than six bedrooms and gracious entertaining spaces reflect the signature Alden and Harlow style. Soaring ceilings, extraordinary millwork, balanced symmetry, and remarkable scale define the interiors. The formal dining room, sunlit Morning Room, and stately Billiard Room recall an era when homes were designed for meaningful gatherings and lasting traditions, including the unforgettable hosting of a twenty eight foot Christmas tree in the grand hall.
For buyers who value substance as much as beauty, significant recent improvements provide confidence moving forward. The sellers have installed a brand new roof along with new gutters and downspouts, and the septic system is being updated. The structural integrity is present. The setting is exceptional. The opportunity is clear.
In a marketplace where so much feels newly built yet lacking character, The Paddock offers architectural pedigree, privacy, and the rare ability to personalize a historic estate while honoring its legacy.
This is more than a home. It is a responsibility, a privilege, and an invitation to restore one of Sewickley Heights’ most storied residences to its rightful grandeur.
