PH Mazatlán is an architectural X-ray of the needs and desires of its inhabitants—a woman and her family—whose domestic coexistence serves as the project's central axis. Located in the penthouse of an International Style building constructed by civil engineer Boris Albin in the Condesa neighborhood, PH Mazatlán is a commitment to movement, transforming and flexibilizing its pre-existing design for a new way of living. The architectural program was expanded to generate diverse communal environments—spaces for reading, studying, conversing, dining, working, and cooking—alongside private areas, such as two bedrooms with independent bathrooms.

Much of the owner's furniture and art collection was preserved; custom bookshelves were designed for her extensive library, lining the entrance corridor, while sculptor Adán Paredes created a site-specific piece that produces fascinating interplays of light and shadow. The furniture, wood, and recinto (volcanic stone) engage in a dialogue with the steel and glass walls and the industrial multipanel ceiling, evidencing a constant negotiation of space and habitability.

Since the project was developed during the COVID-19 pandemic, cross-ventilation, double-height ceilings, and a spacious terrace overlooking Av. Reforma became paramount. Consequently, landscape design took on a significant role, framing the exterior views while providing protection from the heat. The vegetation emulates the lush quality of a forest through a variety of plants, trees, and shrubs, including rosemary, fescues, olive trees, junipers, ayubes, sages, and santolinas.
