InAI is an award-winning architectural office focused on crafting space, light, material and form that respond effortlessly to the specifics of program, function, budget and site.  For each project, the office strives to uncover the rare intersection between the latent and the tangible, the logical and the perceptual, the pragmatic and the sublime.

Dedicated to innovation, the practice is committed to researching and discovering the unique, often hidden, potentials and qualities of every project and using them as creative catalysts for engaging the design process.

Based in San Francisco, the office works both in the Bay Area and beyond with many of its projects located in North Bay, San Francisco and Silicon Valley.  As founding principal of InAI, Leonard Ng leads and directs a multidisciplinary studio team with background in architecture, construction, carpentry and landscape design.
