Designed by celebrated architect Frank Furness in 1878, Lainshaw was the childhood home of Robert Montgomery, who co-founded the investment firm Janney Montgomery Scott and built the Villanova estate, Ardrossan. Lainshaw was originally built for Robert’s father, William W. Montgomery. The home was named "Lainshaw" after Montgomery's Scottish roots. Architectural Heritage: Lainshaw showcases Furness's signature craftsmanship with preserved features like intricate moldings, original stair railings, and exquisite fireplaces. These historical elements are beautifully complemented by modern updates, including a gourmet kitchen with a spacious island, a redesigned office with custom cabinetry, and an open-concept family room that ensures seamless flow throughout the home. Other recent improvements include a new roof with copper gutters and downspouts, new insulation in the roof/ attic, repointed chimneys, low-maintenance Hardie-plank siding, new Pella windows throughout, a Lutron lighting automation system, extensive professional landscaping and outdoor lighting enhancements, multi-zone heating and cooling, and radiant heat flooring in kitchen, family room and primary baths. Elegant Design and Exceptional Features: Nine and ten-foot ceilings throughout invite an unexpected and welcome abundance of natural light through large windows. This six-bedroom home features five full bathrooms and one powder room, plus a cozy sunroom, butlers pantry (with original cabinetry), a billiards/media room, an upper level laundry room, and a luxurious primary suite offering two primary baths, both with heated floors for a spa-like retreat. Indoor-Outdoor Living: The private lot is enhanced by an the expansive stone patio complete with a wood-burning fireplace and hot tub, and surrounded by lush, established gardens. The side brick patio includes both covered and uncovered seating areas, and is accessible from the family room, dining room and living room. You’ll appreciate the easy indoor-outdoor flow for day-to-day living, and when entertaining a crowd. Lainshaw offers a unique opportunity to own a piece of Main Line history - and add your own chapters to its future!
