Berrini 500 is an iconic building built in 2000, designed by architect Ruy Ohtake. Although it has always been posed as a great option for corporate occupation, the building needed readjustments and updates that could further improve its efficiency and make it look more modern. After a thorough study, Barzel opted for implementing a retrofit process. Nowadays the building has state-of-the-art facilities, a modern lobby, exclusive transfer elevators to access the garages, an auditorium, a large bicycle rack with locker rooms. Currently, Berrini 500 is an efficient modern building with LEED Gold certification, completely repositioned, serving as a space for different companies.

Built in 1993, Centro Empresarial do Aço (CEA) was for many years considered one of the largest buildings in metallic structure in Latin America. With a privileged location, the building has always presented the qualities of a resilient property, the reason why Barzel decided to invest in its revitalization and improvement through the retrofit. Nowadays CEA maintains the same characteristics of the initial project, such as the metallic structure, but has turned into modern construction, with more light and cozy spaces, new landscaping and efficient flows, in addition to the new design of the common areas.

Built in the 1980s, Pinheiros Corporate is a valued and well-located development. Since it stands in a strategic area with few corporate buildings of the same standard around it and considering the age and deficiencies of the building, Barzel carried out a depth study and understood that the building would need to be modernized to make it more functional and suitable for nowadays. Now Pinheiros Corporate has a modern facade, a new lobby, a unified reception and new services, including a bicycle rack with locker room. In addition, it has improved the internal flows of users, visitors and suppliers.

Condomínio São Luiz stands out for its imposing architecture and the gardens designed by the famous landscaper Burle Marx, which were accessible only to users of the building. After a wide retrofit in the common areas, jointly made by Barzel, Kinea and Tellus, the walls around the building were removed, making access to this green area public. In addition, the reception was centralized, the elevator areas were renovated and the building was completely modernized.

O edifício Sompo, localizado estrategicamente na região da Paulista, foi incorporado pela própria Sompo Seguros e entregue no ano de 1995. Em setembro de 2022, a Barzel adquiriu o edifício e investiu na sua revitalização através do retrofit. Com mais de 9 mil m² de área privativa, o projeto visava a modernização de todas as áreas comuns e a melhoria no bem-estar e no fluxo dos usuários e visitantes. Em todo o processo, buscamos manter a identidade do edifício, que é bastante popular e representativa do entorno.
