Charming historic farmhouse just south of Boulder on 3.4 fenced acres with mature trees and lovely views of the Flatirons and Eldorado Canyon. Located in the highly rated Boulder Valley School District, this gated sanctuary in the beloved Old Marshall community offers a cozy, character-filled living space and agribusiness potential. The property is a true horse setup with a 4-stall barn, arena, pastures, and direct access to miles of trails from your doorstep. On the main floor is a cheerful kitchen, cozy living room, 2 bedrooms, and a convenient office. The basement is finished (with concrete floors) with several rooms that can be used as bedrooms, workout space, hobby room, or storage. Boulder County has confirmed the potential to build a new home (or add on to the current one) up to 3,100 sq ft, and to rebuild the current outbuildings. The well is permitted for an abundant 12 GPM and 0.75 acres of irrigation. The septic system is approved by Boulder County Septic Smart for a 2-bedroom house. Conveniently situated with quick access to Boulder, Denver, and I-70 for mountain adventures. A rare combination of history, community, location, and future potential.
