Swift Lee Office

Swift Lee Office (SLO)

Swift Lee Office is a Los Angeles-based architecture firm leading through design that responds to a changing world with imagination, discipline, and care. Co-founded by Gloria Lee and Nathan Swift, SLO designs housing, civic, and community spaces that are accessible, adaptable, and sustainable.

Their work blends creativity and responsibility to strengthen both communities and the environments they inhabit. From educational facilities to emerging housing prototypes like the A⁺DU, SLO’s mission is to expand affordability, equity, and resilience through systems-based, net-zero design and thoughtful architecture that uplifts daily life.

The A⁺DU is a 21st-century Accessory Dwelling Unit prototype that makes independent living possible for people of all ages and abilities. Created by Swift Lee Office, it’s a flexible, energy-efficient home that adapts gracefully to life’s changes.

This 467-square-foot home features an open living area, full kitchen, bedroom, loft, and modern bathroom with a roll-in shower and built-in bench. Guided by universal design, the A⁺DU offers adjustable-height countertops, accessible sinks, and integrated smart-home features. Its compact footprint supports both aging in place and multi-generational living, fitting naturally into Los Angeles neighborhoods.

Sustainability is built in—from the solar-ready roof and rainwater collection tank to energy-efficient heating and ventilation. Finish options such as board-and-batten siding, smooth stucco, cedar shake, or black horizontal cladding let each homeowner personalize their A⁺DU.

Recognized with an Honorable Mention by the L.A. County Housing Innovation Challenge, the A⁺DU expands the idea of the accessory unit into one that is Accessible, Adaptable, Affordable, and Aspirational—a small home designed for a changing world.
