Headed by Gracinha Viterbo, Viterbo Interior Design was commissioned to design the entrance lobby, indoor swimming pool, outdoor pool area, spa, gym, and cinema of the building. Viterbo’s design scheme brings a sense of mystery and discovery to the communal areas of Castilho 203 inspired by Lisbon’s narrow alleys and unexpected turns. Challenged to create interiors that would not feel disconnected from the building’s impactful architecture, Viterbo plays with tactile surfaces and organic shapes to create an almost futuristic journey, where fluid lines and organic shapes counterbalance the very robust and linear building by XR Architects.

As with every Viterbo ID project, all details were carefully thought and exquisite Portuguese craftsmanship can be found in every corner. Featuring bespoke art installations by contemporary artists as well as established and young brands, Viterbo’s design of Castilho 203 seamlessly incorporates the work of several local master artisans working in wood, copper, marble and brass. At the spa’s front desk, a suspended installation by Floral Designer Violetta Goldaracena transforms what would otherwise be a rather dark area. Linens and velvets also feature in Viterbo’s earthy material selection.
