On one of Altadena's most treasured streets, 2509 Boulder Road sits in the Country Club neighborhood, just moments from the club, golf course, and the shops and restaurants of Mariposa Village. The flat 11,725 square foot lot is shaded by old-growth trees and mature plantings. An approximately 550 square foot casita, a two-car garage (both fully preserved), and a pool with spa remain at the rear of the property. This setting provided a poolside entertaining space between the home & casita giving it a private, resort like feel. Vegetation that has settled in over decades frames the area. The neighborhood still boasts many character homes, and the streets retain the calm beautiful vistas that define Altadena. Boulder Road is a quiet neighborly community and is not considered a drive through street. It retains its calm, tree lined, views of the mountains as well. This was once the site of an approximately 4,000 square foot two-story home, with five bedrooms and four bathrooms. With Phase 2 debris removal complete, the property is cleared and ready for what comes next. The land is being sold as-is.
