Step inside the first home built on idyllic Mariposa Street in Altadena and step back in time! This private 1917 Craftsman home is artfully sited on a .39 acre flat lot, offering captivating views of the San Gabriel mountains on a quiet, tree-lined street just minutes away from a growing list of the hottest restaurants, coffee shops, shopping and businesses that call Altadena home. The charm and beautifully preserved original character of the home have been lovingly maintained, and the textures of the Arts & Crafts movement lend a sense of history to a home equally well suited for today's lifestyle. Behind the rugged river rock stone wall and flanked by two hundred-year-old Canary Island Palms, the home features one bedroom on the main level and four additional bedrooms on the second level. With multiple outdoor areas including a deep front and side porch as well as an expansive back patio with views of the mountains, the home is an idyllic haven for quiet relaxation or festive entertaining. Inside, the home's craftsmanship and original detail will transport you to a time when things were built to last. Original hardwood floors, lovingly maintained and recently refinished, flow throughout and anchor the space. The high-ceilinged living room with fireplace boasts original woodwork in a deep, warm tone and opens to the formal dining room which includes an original built-in sideboard/buffet, as well as glass inlaid French doors that lead to the porch. The light-filled kitchen with breakfast nook exudes retro charm with an open view of the backyard, as well as a pantry closet and laundry adjacent. Offering a quiet place to work from home, the library features built-in shelving and cabinetry, while the first floor bedroom also works beautifully as a comfortably-sized family room. A large full bathroom rounds out the main floor. Ascend the staircase to find four additional bedrooms, and an equally impressive full bathroom with two sinks and abundant storage. The property includes a one-car garage and offers ample space for a pool, ADU or private gardens. Electrical was fully upgraded in 2022. Entertain friends and family on the expansive back patio, enjoying the nature and charm of the sweeping .39 acre property. Don't miss out on this rare opportunity for a true historical gem in beautiful Altadena.
