Somewhere behind this leafy garden wall, which rises 14 ft. high along Mason and Pacific streets, a 1910 home in Montrose’s Avondale area has been holding on to another era — and another city, maybe. From the garden gate at curbside (top), glimpses inward, toward the brick-paved courtyards and patios (middle), appear to be a bit more challenging than the views outward from the pier-and-beam property. Its neighborhood watch vantage point is located south of Fairview Ave. on a corner east of Taft. St., borders 21st century townhomes, and features a mid-century commercial space across the street that’s brewery bound. Listed a week ago, the self-secluded spread has a $875K asking price.
