A Usonian-inspired Mid-Century Modern retreat set on a private 1.27-acre tree-lined lot along prestigious Cathcart Road in Blue Bell. Defined by its clean architectural lines, expansive walls of glass, and seamless indoor-outdoor integration, this all-brick residence embodies the essence of iconic Mid-Century design, thoughtfully updated to deliver both character and turnkey comfort. A restored terra cotta entry and exposed brick foyer introduce the home's distinctive aesthetic, drawing you toward a stunning central courtyard framed by sliding glass doors and clerestory windows. This striking design creates a natural connection between interior spaces and the surrounding landscape, ideal for both everyday living and elevated entertainment. The main living wing features a dramatic open-concept layout with soaring vaulted ceilings, anchored by a double-sided gas fireplace and custom built-ins. The chef's kitchen has been fully reimagined with custom soft-close cabinetry, quartz countertops, designer lighting, and a premium Dacor appliance suite creating a true entertaining showplace. A private office, powder room, and expansive family room - complete with a wood-burning fireplace and vaulted ceilings-provide additional flexibility and comfort within the home. The private bedroom wing offers a tranquil retreat, with all rooms positioned along the opposite side of the courtyard for optimal separation. The primary suite features a custom walk-in closet and a spa-inspired bath with a freestanding soaking tub and Kohler electrostatic shower system. Three additional bedrooms-one ensuite-are complemented by a beautifully updated hall bath, each space reflecting a seamless blend of modern refinement and original architectural character. A well-appointed laundry/mudroom offers both functionality and style, with custom cabinetry, quartz surfaces, and direct outdoor access. Enhancing the home's versatility, a private-entry in-law or guest suite above the attached oversized two-car garage includes a full bath. Natural gas and water lines are in place for a kitchenette-ideal for multigenerational living, extended stays or a dedicated home office. The oversized garage is finished with a professionally installed Aspartic coated floor, upgraded lighting and abundant overhead storage.
