Site Features


Jef + Leonor Residence is a two-bedroom home located in Cornville, AZ. The home is built on a two-acre plot and it brings unique contemporary design features. The project site has a nearly flat topography, ideal for preserving unobstructed views.



Unique Program Placement



The design maximizes the interaction between indoor and outdoor environments and the site view opportunities are maximized in the design. The design also introduces a novel concept of positioning the kitchen at the center of the house, challenging traditional layouts and promoting a central hub for family activities.

Material Expression

The combination of vertical siding, wood, and possibly terracotta materials introduces a visually appealing texture to the building’s exterior, making a lasting impression.
