estudio felipe escudero (EFE) explores the plasticity of concrete, a challenge highlighting the curves and textures in several scales, with its project recently built in cumbaya, ecuador. casa roca’s curved skin of exposed concrete surrounds and hugs the three sides of the construction and offers a cozy privacy in its interior spaces. windows appear from this solid skin giving birth to beautiful views into the nearby mountains.

the rustic wood framework was made to form the textured concrete, and in some areas the material was polished. those who enter casa roca will notice the calming sensations of interior spaces, as opposed to what happens outside in the dense residential neighborhood full of speed and daily entropy. here we travel to a sanctuary where rest and intimacy presume its dominance in the space composed of white walls, wood and vegetation, and of course, the exposed concrete.

materials selected by EFE are characterized by their purity — they were treated without coverings in order to give dignity to the constructive system. you can feel how ventilation and light enter through various vanishing points, easily, subtly, as if entering a natural environment inside the house.

the living and dining rooms share a ten meters by nine meters double height space located in the center of the floor plan. the ceiling — a constant texture through the house — becomes an element of decoration, a gift of the material that shows an infinite variety of shapes.

‘the jewel of the house’ — as felipe escudero calls the staircase — is a curvilinear sculpture made of wood suspended in space with only two points of support. the stairs are connected on the second floor with a wooden bridge that separates the master bedroom from the other bedrooms. this bridge is a transition between the private spaces of the house, full of vegetation with plant pots that include a system of irrigation and intelligent drainage.


the bridge and stairs are the centerpiecese of the house — they were treated as sculptural pieces to every detail

 

 

the hug culminates in the rear façade, which opens onto the patio with floor-to-ceiling windows. when they are opened, they hide in wooden pockets and reveal the lack of boundaries between the inside and the outside. the exterior, on the other hand, contrasts in character with the rest of the house. here, where the social activities happen, the space is protected by lateral walls and 25 meters of a cantilever that isolates the space from exterior sound and wind. this is where the weekend barbecues and various festive ceremonies, typical of many latin american cities, can happen.
