The historically designated Jach Residence (1962), constructed by Master Builder John N. Mortenson, embodies the tenets and stylistic features of Mid-Century Modern architecture. Situated at the end of a serene cul-de-sac on coveted Russell Road, this exquisite home combines privacy, modern design, and breathtaking views. The meticulously remodeled and maintained home boasts updated bathrooms, kitchen, living spaces and landscaping, while preserving its iconic mid-century features such as the vaulted wood-beamed ceilings, floor-to-ceiling windows, a stone walled fireplace with sunken conversation pit, a mid-mod bar and a circular driveway with attached porte-cochere. With its architectural pedigree, Mills Act tax savings, saltwater pool, stunning views, and impressive upgrades, this John Mortenson masterpiece captures the essence of Mt. Helix living at its finest.
*Taxable value of land and structures on it ("additions") is determined regularly by local assessors and does not affect market price.
