About us
Betarq is a studio of architectural services based in Barcelona founded by Ramón Cisa, Sergi Barquet and Julio López.


"Bet" is the second letter of the alphabet of the ancient Mediterranean cultures and symbolizes "home". Its graphics is a square that represents the plan of the walls of a house in which the left side is missing, thus showing the essence of the enclosures of a house, as well as its will and need to open up to the outside, to relate. "Arq" is the Greek word that translates as "first", "primordial" or "preeminent". All this symbology seemed very appropriate to us, since the purity of these roots fit perfectly with our way of thinking and with the respect we have towards the fact of inhabiting a specific space. In this sense, we try to maintain a high value of all the aspects that are part of the construction process of a building: place, ideas, materials, requirements or personal relationships, regardless of their scale. Services Betarq provides personalized attention and deals with everything from the economic study to assess the feasibility of a real estate operation until its delivery to the final client, going through any phase of the project. Within architecture services, the team realiza proyectos (básicos, ejecutivos, direcciones de obra y ejecución), y se encarga de la gestión de obras (Project Manager) y de la realización de project audits.
