The City Park ADU Residence

ADU
Written By Phillip Daughton
Two-story design-build ADU in Denver featuring an integrated garage, fiber cement siding, and modern window placement, built by Prenvalley Builders.

Project Overview

The homeowners wanted a flexible, private living space that could comfortably support guests or long-term rental use on an urban Denver lot. Prenvalley designed and built a two-story ADU with an integrated garage, full kitchen, and multiple bedrooms, creating a space that functions like a true home. The project required thoughtful planning to balance access, privacy, and efficiency within a compact footprint. What makes this ADU special is its scale and livability, offering far more than a typical accessory dwelling unit.
