With a business trajectory now approaching 40 years, our company’s team has carried out widely recognized and award-winning restorations, over 40 of them on historic buildings and ensembles designated as UNESCO World Heritage Sites.
In Spain, we have restored many of the finest buildings in the historic centers of such cities as Madrid, Barcelona, Seville, or Toledo, and magnificent cathedrals such as those of Santiago de Compostela, Seville (where we have been working uninterruptedly for the past eight years), Sigüenza, Toledo, Cuenca, Tudela, Coria, Almería, and currently the Cathedral Basilica of El Pilar in Zaragoza, as well as monasteries, convents, and other religious buildings.
We have deployed our expertise to other European countries, both in the rehabilitation and restoration of historic buildings in France, Portugal, Italy, or Switzerland. From our offices in Lisbon and Paris, we have worked in their urban centers and on such iconic buildings as the Palace of Versailles or the Centre Georges Pompidou.
In Chile, we have an operational center with a multidisciplinary team that supports work in several Latin American countries. In addition to participating in some of the most significant heritage conservation projects in Chile —such as the rehabilitation of the Vergara Palace in Viña del Mar or the Pereira Palace in Santiago— we have also intervened in the former Velasco Sarrá Palace, the current Spanish Embassy in Havana, Cuba, and in the Primate Cathedral of the Americas in Santo Domingo, Dominican Republic.
We are working on the preservation of architectural heritage in the United States. From our New York office and Miami branch we are restoring facades, interiors, and distinctive features of public, residential, and religious buildings, including several projects in the states of New York, New Jersey, Wisconsin, Connecticut, Pennsylvania and Florida.
We have worked continuously with reputed institutions and companies such as the insurers Zurich, Generali, Mapfre, Catalana Occidente, etc., the Bank of Spain, Santander Bank, Telefónica, General Electric, Kennedy Wilson, or the largest business group in the retail sector, owner of the most extensive portfolio of historic buildings worldwide. Such heritage owners put their properties into the hands of firms offering the highest guarantees.
This is possible thanks to our own staff of highly qualified and reliable employees: fine arts graduates, restorers (with various specialties, such as mural painting or sculpture), and masters of traditional building trades, such as specialists in lead and zinc, woodwork, reproduction of architectural elements, stuccos, sgraffiti, etc., overseen by highly trained and experienced technicians.
Through our Project Support Department we collaborate with architects and heritage technical teams, providing them with rigorous reports that added value to the conservation of buildings. In this way, we have developed proposals for the restoration of heritage in Georgia, Uzbekistan, and other countries such as Angola, with turnkey projects like the full rehabilitation of the Helder Neto Institute, carried out for the Ministry of Fisheries, a logistical challenge that included a significant portion of new construction.
We, the professionals forming the KALAM GLOBAL team, remain committed to every project to earn the appreciation of the owners of public and private buildings and to contributing to upgrades that will enhance their value.
