Collective Tiny Homes: A Hybrid Between Single-Family Subdivisions and Multi-Family Housing

In Sedona, AZ, middle-class single-family homes are typically added through either subdivision development—often disturbing virgin land and requiring private water wells and septic systems—or multi-family housing, which is less appealing due to the lack of front or rear yards. As an alternative—a hybrid of these two typologies—the concept of collective tiny homes was explored in the Village of Oak Creek, AZ.

Nine 900-square-foot pavilion structures are planned for a 0.82-acre site with a gentle slope, located on the edge of town with sweeping views of the iconic Bell Rock and Arizona’s desert landscape. As the "collective tiny house" typology is new and untested, it was challenging to find clear evidence of demand for this type of housing. To mitigate this challenge, the final scheme was proposed as hotel units for a soft launch of the concept. In compliance with Yavapai County Zoning, the tenth pavilion was replaced with a dining hall.

Rain Gardens

The site is composed of a series of flat pads, each separated by only a few inches in elevation, creating platforms for buildings and rain gardens. These pads closely follow the existing topography, preserving the natural stormwater flow. As runoff moves through the site, it sequentially infiltrates each rain garden before any excess water is collected in a cistern beneath the parking area for future irrigation.

9 Rain Gardens, 9 Platforms

Nine rain gardens, located in front of each pavilion, are designed as flat planting areas with 6-inch level differences, creating a step-like landscape. They are all interconnected through open culverts. The rainwater will soak into each rain garden sequentially, slowing the stormwater runoff. Excess runoff will be stored in a drywell beneath the parking area for future irrigation.

Density and Privacy

Large windows were incorporated to bring ample daylight and create an inviting atmosphere. For example, south-facing windows and patio doors fully open to the private rain gardens, visually expanding the living space into the outdoors. Other large windows are strategically placed above eye level or behind concrete screen walls to maintain privacy without sacrificing openness. Each of the nine pavilions was carefully positioned and mirrored to allow occupants to enjoy direct, unobstructed views of the dramatic Sedona landscape and Bell Rock.

Wild Plants in the Desert

Wild plants naturally appear along slow stormwater runoffs in the desert, providing a distinct and pleasant feature. Rather than designating a large area for stormwater management, nine small rain gardens were designed and connected throughout the site. These rain gardens also serve as private gardens, marking the entryways to each pavilion. Given Arizona's position as the third driest state, a key goal was to ensure the stormwater was evenly absorbed across the site before reaching the cistern and detention tank.
