Casa Santa Ana is a contemporary residential renovation located in Vitacura, Santiago, Chile. Originally a single-story house, the project preserves the existing structure and footprint while introducing a new second floor to redefine spatial quality and natural light.
The ground floor features an open-plan kitchen seamlessly connected to the living and dining areas, fostering openness and everyday comfort. Private spaces—including bedrooms and bathrooms—are located on the upper level, where full-height windows enhance spatial amplitude and bring generous daylight into the interiors.
Wooden cladding defines the façade, creating a lightweight architectural expression that minimizes visual impact while reinforcing warmth and calm. Through material simplicity, natural light, and spatial continuity, Casa Santa Ana transforms an existing home into a serene, modern living environment.

Casa Santa Ana is the result of a thoughtful remodeling of an existing home
in a residential neighborhood of Vitacura, Santiago. The project begins with a simple
but decisive gesture, preserving the original structure and footprint of a former one-story
house while redefining its spatial and architectural character through vertical expansion.
The new organization clearly separates daily life from private spaces.
The first floor is conceived as a continuous and open environment where the kitchen,
dining room, and living room are fully interconnected, accompanied by a discrete
service area. This level functions as the social heart of the house, open, fluid,
and filled with natural light throughout the day. Above, the second floor accommodates the
more intimate program. Bedrooms, bathrooms, and a family living room are arranged within a light,
carefully proportioned volume that rests gently over the existing structure.
Large windows extend across the full height of this upper level, enhancing spatial
amplitude while framing views and allowing daylight to deeply penetrate the interior.
Wooden cladding is prioritized on the facade, giving the house a warm,
natural expression while visually lightening the added volume.
This material choice minimizes environmental impact and reinforces a close relationship
between architecture and context. Inside, the integration of kitchen, dining, and living spaces,
combined with constant natural light, creates an atmosphere of calm, warmth, and openness.
Casa Santa Ana is not a radical transformation, but a precise and sensitive intervention,
one that renews domestic life while respecting what was already there,
achieving balance through light, materiality, and spatial clarity.
