Welcome to 42 Spring Valley Street, a beautifully updated Civil War-Era home, built in 1860 and preserved and modernized for the present day. Located in the heart of Beacon and set on an expansive corner lot, this 2,245-square-foot residence offers an open, sun-filled floor plan on the main level, featuring original wood ceiling beams, exposed brick, and wide-plank floors throughout. The spacious living room is anchored by a cozy wood-burning fireplace, while the dedicated dining area leads into a chef’s kitchen with ample storage and prep space. A full bathroom and comfortable bedroom complete this level. French doors open to a newly-installed, large stone patio and a fully-fenced grassy backyard that is a paradise for gardeners and bird lovers. With a handsome new shed and an inviting raised garden area, the private, oversized yard offers a welcome space for green thumbs. On the second floor, you'll find three bright and airy bedrooms with more exposed wood beams, a laundry closet, linen closet and pantry, and a full bath with radiant heat and a luxurious jacuzzi tub. The fully-finished third floor adds approximately 600 square feet of versatile living space, not included in the home’s official square footage, perfect for kids' bedrooms, offices, studios, or a music room. Located on the gorgeous, quieter "mountain end" of Beacon, the home is just steps from the vibrant shops, cafes, and restaurants of Main Street (Hudson Valley Brewery, Roundhouse, Vinyl Room, Stanza Books, Melzingah, the movie theater, and much more), while also two blocks from a picturesque waterfall and a short walk to iconic hiking trails. Additional amenities include off-street parking and an EV charger powered by solar panels on the newly replaced roof. An ideal home for those who are looking for the serene beauty of the Hudson Valley while also wanting immediate access to the charms of Beacon and the convenience of the Metro North train, with an easy commute to Grand Central.
