The ph5 studio was created in 1994 as the architectural part of the P.H.A. studio, founded by the architects V. Červenka and O. Gattermayer in 1991 in Lausanne. Over the course of these fifteen years, a great number of implemented and unimplemented projects were created in the Czech Republic, Slovakia and other countries around the world (Switzerland, Ireland, France, Canada, Russia, Ukraine....) in the field of architecture, interior production and design. A significant part of the work created by the ph5 studio is made up of projects for gastronomy operations. Examples of work implemented include the first Potrefená husa, the Na verandách pub (awarded Interior of the Year 2001), the Lamborghini restaurant, Brasserie M, Brasiliero, Da Emanuel, the Louvre gallery, the Lokál pub and others.
