The Portuguese landscape at the Quinta da Monte d’Oiro is home to the Mediterranean climate and Atlantic influence whose identity is grounded by its locale characteristics of earthy minerals, hot summers, and rolling hills. A mixing of cultures gave birth to centuries old craftsmanship, process, and rigor found in wine making and construction. The traditions and craft of wine making at the Quinta Monte d’Oiro are perennial and romantically sensorial in nature but as the world and notably the hospitality
CONTEXT
and food industries have been disturbed by the rise of the COVID-19 pandemic (project submitted in July of 2020). In response, to knowledge that viral spread is significantly less outdoors and lessened indoors with use of enhanced ventilation, the project seeks to "open" to the outdoors as much as possible. This also aligns with Mediterranean traditions in such a temperate climate; air conditioning is a 60-year old invention in an place with traditions spanning thousands of years.
The project’s focus was to provide an accessible unit at a compact footprint. The floor plan intentionally avoids the typical appearance of accessible spaces, creating a more seamless and integrated design. The base project contains a mix of ADA and ADA ready elements with modifications noted on the plan on how to adapt elements shown. The clearances are also shown on the plan.
LAYOUT
Targeted upgrades maximize cost-effective impact. Corrugated metal panels highlight the main entry. The built-in kitchen island doubles as a dining table and includes shelving to integrate the TV. A single skylight brings natural light into the living space. Built-in elements, such as the desk and laundry counter, provide ample workspace and storage, eliminating the need for separate office or laundry rooms.
SITE
This ADU focuses on efficiency, offering a flexible 1-bed, 1-bath layout that can adapt to a wide range of lot sizes, orientations, privacy preferences, and budgets. The design consists of two separate modules: a living/dining/kitchen module and a bed/bath/laundry module. A second bed/bath/laundry module can be mirrored on the opposite side of the living/dining/kitchen module to create a 2-bed, 2-bath unit if desired.
The patio allows for the ADU to create interaction with the existing homes patio, say as part of a multi-generation concept. If privacy as part of a separate rental unit on a lot; then the patio can be rotated away from the home towards an alley or side entrance.
CONSTRUCTION

The ADU is constructed using standard, low-cost materials commonly found in typical developments across Tempe. It features a minimal yet sufficient 4” slab-on-grade with a downturned edge, reducing the need for costly exterior walls and large footings. Framing consists of 2x wood stud walls and a conventionally framed roof.
Exterior finishes are modest and familiar: medium-textured stucco, black vinyl windows, asphalt shingles, and painted brake-metal fascia. Accents are also of standard materials: corrugated metal panel, black metal wall sconces and building numbers.
