The landmark of Piraeus, located in the heart of the largest passenger port in Europe, began construction in 1972 but remained unfinished and vacant for decades. Finally completed in 2023, after an international competition, it now stands as Greece's first green and digital skyscraper. The architectural firm PILA took on the design of the facades, while the office ASPA-KST designed the commercial spaces, and the new general architectural study was entrusted to Betaplan. After over four years of renovation, Piraeus Tower officially opened its doors to tenants and visitors on June 4th with a night of celebrations, establishing itself as a bustling hub and injecting vitality into the area.

Beyond the wide variety of landscape, environmental, economic, social, and cultural particularities that distinguish each region of Latin America, the renovation of interior spaces that make up domestic life generally focuses on achieving the greatest possible integration of environments along with providing flexibility, spaciousness, and better conditions for ventilation and natural lighting. Seeking to revalue unused spaces and/or give them a second life, renovations aim to transform the ways of living through strategies capable of involving the restoration of materials, the preservation of structures, the maintenance of installations, and more.

Listed buildings are important architectural testaments to a society's rich and diverse history. Formally recognizing these buildings protects their significant architectural elements from alterations and demolitions while creating socio-economic avenues to aid their conservation. However, these buildings also run at risk of being alienated from new materials and modern building systems that allow them to function optimally today.

Refurbishment is an increasingly common and fundamental practice in contemporary architecture. More than a trend, it represents a crucial strategy for reducing resource consumption and minimizing waste generation, providing clear advantages over brand-new constructions. In the Latin American context, this philosophy stands out for its unique characteristics. It intricately weaves circularity and climate action with local materials, addressing economic challenges while harmonizing Indigenous, colonial, and contemporary influences.

Evolving urban conditions call for an evolving builtscape, and retrofits have been a key mechanism to allow buildings to adapt and respond to new needs. Amidst global environmental concerns, climate retrofits have become a popular strategy to upgrade buildings based on improved operational efficiency. Global decarbonization plans have even called for city-wide retrofits, such as in the case of London, to meet civic goals. While such upgrades significantly reduce energy consumption, they often come with a hidden cost - embodied carbon in retrofit materials and the potential for future waste.

Industrial heritage, once central to urban growth and economic prosperity, is now often neglected and underused. Around the world, various factories, mills, and warehouses sit abandoned, and their distinctive structures fall into disuse. These buildings were typically constructed from materials such as brick, steel, concrete, and large glass windows. Known for their strength and longevity, these materials make the structures ideal candidates for refurbishment, maintaining structural integrity.

In response to the Czech Republic's soaring real estate prices, architecture firm KOGAA has transformed a former storage facility in Brno into DADA Distrikt, an affordable and diverse housing development. The project's economic approach, achieved through shared funding and direct sales, bypasses extra costs associated with developers while refurbishing a part of the city’s industrial heritage, transforming it into an active urban district. The project also features sustainability measures aimed at lowering its maintenance costs, further exemplifying the intersection of affordable housing, heritage restoration, and sustainable urban living.
