A distinguished Boise residence rich in history, elegance, & possibilities. As the historic neighborhoods developed, this exceptional property stood at the heart of a growing city. One of Boise’s residential treasures – preserved architectural integrity & significance, backing to the Warm Springs canal on over 1/2-acre and equipped with geothermal heat. Built in 1902 for the family of Boise pioneer & former mayor Peter Sonna, the residence reflects an era when craftsmanship was uncompromising, entertaining was an art & homes were designed to serve generations. Rich wood floors, extraordinary millwork, original pocket doors, handcrafted built-ins, vintage light fixtures, stained glass & beautifully preserved wallpaper tell the story of a home that has been celebrated & cared for by generations. Grand formal rooms, including an elegant dining room, gracious living spaces, library, & veranda capture the warmth and sophistication of another era while offering incredible beauty and function for today's living. The residence provides many possibilities for its next steward -- to continue as an elegant & grand estate, serve as a multigenerational home with two living spaces, be thoughtfully transformed into luxury condos, converted to live/work or to an elegant office.
