She founded the architecture firm Bernardi Peschard Arquitectura in 2000, focusing mostly on residential and corporate projects.
She has stated her path to architecture began when she was eight years old, when she designed a pool to be built in the empty lot next to her family's home.
She also stated that blending her personal and professional lives has resulted in a search for balance between durability, neutrality and timelessness in her projects, based in her personal struggles balancing “family life, being a mother, and her work.”[4][5] Peschard has designed private homes, residential projects, and mixed-use corporate offices in Mexico since 1991.
[4] In 2017, Peschard stated that it's important to “Try to invent new things, not to copy either the Mexican or the foreigner... [but to] search our history and combine what we find with technological and technical advances to create something personal and innovative.”[4] Her interior designs often "revolve around art," and her buildings have included furniture pieces by Henge, Ceccotti, Minotti and Christophe Delcourt.
According to Architectural Digest, the harmony of space in her designs is achieved "due to the application of a sober color palette, where gray tones and a contrast of natural woods converge.
