About This Property

Timeless Elegance in the Heart of Old Town, one of Longmont's most distinguished historic residences, The Emmons-Adler House. A rare opportunity in turn-of-the-century architecture, bold, symmetrical, and commanding on its half-acre lot along coveted 3rd Avenue. The crown jewel of the exterior is the sweeping wrap-around porch, perfectly proportioned to match the home's stately presence. Whether you're sipping morning coffee as the neighborhood stirs to life or hosting friends on a warm Colorado evening, this porch is the kind that makes passersby stop and stare. It is quintessential Old Town living at its finest. Inside, over 5,000 square feet of thoughtfully arranged living space unfolds across three generous bedrooms, three bathrooms, and a spectacular bonus third-floor great room. Throughout the home, soaring leaded-glass windows cast ever-changing light across richly appointed rooms, their artistry a daily reminder of the era's uncompromising craftsmanship. Deep woodwork, gracious proportions, and the quiet confidence of a home that has stood beautifully for over a century complete an interior that no new construction can replicate. The historic designation confers a deep sense of pride of ownership and places this property among a rare and celebrated collection of Longmont's most treasured homes. The grounds are nothing short of exceptional. The rare half-acre lot is lushly private and serene - a true urban sanctuary in the heart of Old Town. A charming garden house anchors the backyard, perfect as a studio, workshop, or haven for the dedicated gardener. The detached two-car garage provides ample storage and parking, while the drive-through driveway adds a gracious, practical elegance. The private garden area is a hidden gem. Mature trees and beautiful outdoor spaces complete a setting that is as livable as the home itself. Stroll to restaurants, coffee houses, breweries, shops, local events, and all Downtown has to offer. Love Where You Live
