Listing description

Some homes are built. This one was conceived. Designed in 1961 by architect P.T. Astore and honored that same year with a national award for residential design, 3705 Darby Road is one of the Main Line's most architecturally significant properties — a Frank Lloyd Wright vision of modernism set on nearly two private acres in Bryn Mawr. The philosophy is immediately apparent: this home does not separate you from the natural world — it dissolves the boundary between the two. Floor-to-ceiling and transom windows wrap the interior in shifting light and seasonal color. A long private drive rises to meet the house, which sits elevated above a private reserve, with surrounding woodland and a koi pond below the patio. The world quiets here. Inside, the integrity of Astore's original vision remains intact. Concrete walls and original concrete floors ground the space. Cedar plank ceilings lend warmth. A dual door fireplace between the dining and living rooms, and an open kitchen-dining-living plan speak to a designer who understood, decades ahead of his time, how people actually want to live. The home's signature symmetry offers genuine flexibility — three back bedrooms, multiple home offices or a fourth bedroom, for multiple configurations! Authentic glass shower tile, and a unique l shape to the bathrooms delight. Dual-zone gas heat and air conditioning, a detached carport with storage shed complete the picture. Plus, the train to Center City or Manhattan is minutes away. Suburban Square, acclaimed restaurants, and leading universities are close at hand. Serenity and connectivity, in rare and deliberate balance. Opportunities like this do not repeat themselves.

Not reported in the MLS feed

Recomputed from the county assessment ($575,480, 2021 base year) × current millage. School millage is from the latest year certified by the Pennsylvania Department of Education (2025-26); districts adopt the next year's budgets each June, and we update when the state certifies the statewide file in the fall. Portals typically reprint the recorded 2026 bill. Pennsylvania does not reassess on sale. Estimate only. Verify with Delaware County before relying on it.

Taxes use NookLocal's estimate at current millage rates, not the stale figure on the MLS. The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
