Established in 2015, Alex Pettas Architecture (APA) is a versatile architecture firm with experience in single family, multifamily, workplace and retail projects. We trace our roots through a California modernism that balances form, materiality and a sensitivity to the natural environment. We work closely with our clients to understand their desires and translate them into built form. The office is dedicated to finding innovative solutions to the design commissions that our clients entrust us with.

We are currently working on projects in Brentwood, the Hollywood Hills, Nashville and San Francisco.
