Come experience the Honorable Claude C. Coffin mansion, a District Judge and a Pioneer family in Northern Colorado! Also an amateur archaeologist, you must see the rock wall that was constructed from fossil rocks collected by the family which stands tall guarding these incredible landscaped courtyards and tree filled grounds. (So quiet and tucked in you almost don't even know you are on Prospect) The same is true with the 2 incredible fireplaces which are made from fossils, gems and special stones that they built both fireplaces with (see the pics!). This excellent craftsman style specimen with a classic rectangular 1 1/2 story style design of ~100 years ago is truly a one of a kind masterpiece! Such a fascinating history makes this a seldom available and rare one of a kind opportunity! Owned by just the 3rd owner EVER of this property, there is also so much more potential to be unleashed! A lovely 4BR 2BA that is currently being used as an over/under duplex (separate full kitchen in the basement) the home is raised so it gets great deal of daylight & natural light through the lookout windows in the basement! So much more potential in the unfinished upper level attic too! The home features immaculate trim, woodwork, doors, thin oak flooring and built-ins that are all master craftsman quality, and almost as beautiful as when they were first installed. The sunny South facing enclosed porch is a really great space to enjoy and offers a further buffer space to the home. The HUGE .8 acre lot and amazing grounds with all of the towering trees and special areas outdoors (where deers still wander) as well as this home itself are a must see! HD (high density zoning) adds to the future potential and long term upside. The special home is also eligible for both State & Federal tax credits, but has NOT ever been designated Historical nor put on the Historical Landmark Registry. Run don't walk! This treasure won't last long!
