The project aims to restore Grandma Carolina's old house in Rabós (Alt Empordà), which has been closed for a period of time, to prevent its progressive deterioration and to make it suitable for family enjoyment during both short and extended stays. Dating from the 18th century, this simple construction consists of a two-level main body.

The upper level serves as the living area, while the lower level originally housed animals and included a courtyard accessed via a passage. The stone-built original structure features small openings, primarily connecting main rooms to the north-facing street facade. Previous improvements enhanced the roof, added an attic and a new courtyard wing with a room, and updated services. The recent intervention harmonizes with these updates, maintaining roofing style, construction methods, and restoring the facade's characteristic pink color.

The renovation goals include improving year-round climate control and reorienting the house to connect the kitchen-living-dining space to the south facade. The main floor is designed as an autonomous unit with essential living spaces.

The attic floor features a new bedroom with a bathroom and multipurpose space resulting from expanded volume opening to the south. Bedrooms, bathrooms, storage, and circulation areas serve as a climatic buffer on the north facade. A new skylight cuts through the slab's vaults to bring natural light and solar gain to the central dining area, known as Ca la Carolina.

At the energy level, strategies include maximizing the thermal inertia of the solid stone and ceramic construction by leaving them exposed. Solar gain is increased through new south-facing openings, while smaller openings on the north and east facades are retained.

Cross ventilation is ensured in all rooms. Summer solar protection is provided by Alicante blinds, shutters, and a vegetative pergola. The envelope is enhanced with wood fiber insulation throughout. Additionally, the home is equipped with a pellet stove for the coldest winter days.

The intervention aims to preserve and enhance the characteristics of the existing construction, incorporating its various layers and previous interventions. It prioritizes minimizing demolition and maximizing reuse of elements like concrete beams, stone, and tiles. 

Low environmental impact materials such as wood fiber insulation for facades and roofs, and wooden windows are used, along with local materials such as ceramics from La Bisbal for flooring and traditional glazed tiles for interiors and exteriors. The project supports the local economy by selecting systems that local workers can execute, thereby valuing their expertise and techniques while reducing travel distances.
