On the rooftop of an early twentieth-century palace in Mexico City, this contemporary intervention shows how valuable structures can be creatively re-used and adapted.
Functioning as a space for cultural and festive events, the palace rooftop previously included three existing, uncovered patios. To make the rooftop space more functional in light of occasional rains that interrupt activities, the owners sought to provide cover. Productora Architects responded with a single proposal: a continuous roof structure, more than 50 m in length, connecting the existing patios and generating a large new covered area on the roof.
In total, the structure includes 45 lightweight metal trusses, each spaced 1.2 m apart. The lightweight truss system serves to distribute the structure’s weight evenly across the existing historic structure. Lightweight materials were also selected, specifically PVC decking, polycarbonate sheeting and railings of nylon nets.
Two different types of polycarbonate, transparent and translucent, acts as a filter for sunlight, while still allowing views to the sky. Another solar control measure is the inclusion of textile screens, which have been borrowed from the agricultural industry.
The geometric rhythm of the structure and its material contrast with the existing historic building have a striking effect, which is emphasized by planters that overflow from the patios and night lighting fixtures that highlight the structure on the city’s skyline.
