About

Baltazar studied and finished his Masters at Faculty of Architecture of Lisbon University having also spent a period of time studding in Versailles at École Nationale Supérieure d'Architecture.

After working and gaining experience in smaller studios he joined Lisbon practice Frederico Valsassina Arquitectos where he worked in several big scale commissions like hotels and residential operations across Lisbon including refurbishments and extensions of classified buildings.

Subsequently established his own practice beginning with residential and touristic projects. The practice, in partnerships, also found a fertile ground to think and develop architecture through public competitions having won residential developments, museum refurbishments or the redevelopment of public spaces thus broadening the scope of the work developed.

Practice

Our practice is grounded in the pursuit of a thoughtful equilibrium between modern design and memory. Architecture not as an isolated object, but as a cultural and spatial continuum shaped by history, context, and lived experience.

This balance allows our work to be both forward-looking and rooted, producing architecture that is legible within its time while remaining deeply connected to its context. By engaging memory as an active design force we aim to create spaces that feel simultaneously new and familiar, precise and emotionally resonant.

We operate across scales and typologies, navigating complexity through methodical research, prototyping, and collaboration with engineers, consultants, and fabricators. Creativity and technical expertise are inseparable within our design process. We believe that strong architectural ideas must be supported—and often generated—through a rigorous understanding of construction, material behaviour, environmental performance, and regulatory frameworks.

At the core of our practice is a commitment to sensibility and critical thinking as fundamental design tools. Every project is approached as a specific condition rather than a repeatable solution.
