Originally known as Ederllyn and built in 1898, Second Tamora is a landmark Gwynedd Valley estate offering architectural permanence, privacy, and confidence rarely found today. Set on nearly 3.5 park-like acres behind a gated entrance, this storied stone manor reflects over a century of thoughtful stewardship—where history has been preserved and essential systems have been responsibly restored and modernized. A long, tree-lined drive leads to a circular courtyard with fountain and four-car garage, setting the tone for a residence designed for gracious living and entertaining. Inside, the home showcases timeless craftsmanship including a grand marble foyer, hand-painted architectural details, multiple staircases, substantial stone walls, and ten fireplaces—three of which are gas—each space offering scale without pretense. Importantly, the current ownership has invested significantly in the property’s infrastructure, addressing the elements that matter most in a historic estate. Electrical systems have been updated with knob-and-tube removed, two commercial-grade generators installed, extensive water management completed, patios and terraces reinforced, landscaping enhanced, and the outdoor pool and spa fully restored. These improvements provide peace of mind and allow the next owner to focus on personalization rather than remediation. The kitchen and baths are functional and ready for a future vision, offering a rare opportunity to tailor finishes without inheriting unfinished structural work. Additional features include a catering kitchen and expansive lower-level spaces suited for storage, fitness, or support use. Beyond the residence, the grounds provide a serene backdrop for outdoor living, private gatherings, or quiet reflection—just minutes from regional rail, major highways, and the conveniences of Montgomery County. The property lies within the award-winning Wissahickon School District and near an array of highly regarded private schools. Second Tamora has welcomed notable guests over its long history and now stands ready for its next steward. This is not a home for everyone—but for the buyer who values architectural integrity, infrastructure confidence, and the freedom to create something truly personal, it represents an exceptional and increasingly rare opportunity.
