Vertical Gardens Spruce Up a Dusty Monument

Inside, a large planting feature designed by Michael Hellgreen of Vertical Garden Design clads the kitchen block. "The idea behind the vertical garden was to bring a natural element to the space, since the overall look was very minimal," architect Duarte Caldas says.

Overall, the plant wall covers over 1,200 square feet of surface area.

A custom bar sits underneath a retractable skylight. The material palette of the interior is simple, with white walls and concrete flooring.

In the dining room, a mural by Sol LeWitt, painted in 1990, was uncovered. A circular theme, introduced in the original project, is reinforced by round lamps throughout the interior.

"The intervention was an exercise of looking back to the original project in order to restore as much as possible of the structure," Caldas says. "Besides removing internal walls and exterior add-ons, we closed and re-opened the framework in order to preserve the facade’s original proportions."
