3753 Residences | Custom Home Build of Duplex Units

PROJECT OVERVIEW

Located in Denver’s vibrant Cole neighborhood, the 3753 Residence is a warehouse-modern speculative home designed to reflect the evolving character of its urban context. Completed while working at Work Shop Colorado, this residence blends industrial materiality with warmth and functionality across three thoughtfully organized levels.

The design centers around a dramatic, multi-story floating staircase that anchors the entry sequence and vertically connects each floor. Expansive glazing and strategic massing ensure that natural light pours through the living spaces throughout the day. The home’s palette—a mix of steel, wood, concrete, and warm finishes—brings contrast and cohesion, creating both visual interest and comfort.

The first floor features an open-concept living, dining, and kitchen area with seamless transitions to exterior patios. The second level includes three bedrooms and a private balcony, while the third floor houses a flexible bonus space ideal for a home office, studio, or guest area—leading out to a rooftop deck with panoramic views.

Architecturally, the 3753 Residence nods to the industrial history of the neighborhood through bold lines, exposed elements, and refined material juxtapositions, offering a fresh interpretation of warehouse-modern design tailored to residential living.
