Old Town Longmont Corner of 4th & Pratt Perfectly placed across from Thompson Park and just two blocks from Longmont's vibrant Main Street, this one-of-a-kind Victorian blends historic beauty with thoughtful, modern updates-and the warmth of a truly special neighborhood. Wrapped in mature trees and a fully fenced yard, this home offers both privacy and connection. Enjoy two flagstone patios ideal for summer dining, garden gatherings, or lazy afternoons in the shade. Step inside through the enclosed sunroom-a cozy, heated space with both windows and screens, perfect for morning coffee or evening cocktails as you watch the neighborhood come alive. The main level features soaring ceilings, original hardwoods, built-ins, oversized windows, and a wood-burning fireplace that anchors the elegant dining area. The open-concept kitchen is rare for a home of this era-offering two generous islands, top-tier stainless steel appliances, a charming built-in display cabinet, and effortless flow for entertaining and daily living. Upstairs, four spacious bedrooms await. The primary suite feels like a treehouse retreat, complete with a walk-in closet and private balcony perched among the leaves. A 2nd bedrm also opens onto its own balcony overlooking the peaceful backyard. The updated bath features radiant heated floors, a luxurious double-head shower, and a custom-imported vanity-adding a bespoke touch to your daily routine. Downstairs, the finished basement includes a third bathroom, storage, a workshop space, and a large flex room perfect for yoga, art, or quiet escape. The original cast-iron boiler is displayed alongside a new high-efficiency system, honoring the past while preparing for the future. Other upgrades include a new roof and 44 storm-protected windows, combining energy efficiency with enduring charm. With no through traffic on Pratt Street, this is one of Old Town's most peaceful and community-centered pockets.
