thin concrete walls frame tiny chapel by S-AR, built from its own remains

S-AR reinterprets a chapel through thin concrete walls

 

Set within a garden in Santiago, Nuevo León, Mexico, the Oratory Chapel by S-AR is conceived as a small-scale structure that reinterprets a previous chapel once located on the same site. The project reuses elements from the earlier construction, establishing a spatial and material continuity between past and present.

 

The chapel is defined by two reinforced concrete walls, each 8 cm thick, set at varying heights along a diagonal. These walls support a thin concrete slab of 6.5 cm, forming a narrow, tunnel-like space. The construction follows a regular formwork modulation, while openings left within the wall system allow light and air to pass through, softening the enclosure. At one end, the increased height enables access into the interior space formed between the structural elements.

reused brick and steel carry memory into the chapel interior

 

Inside, a wooden bench rests on a floor of crushed red brick, introducing a contrasting texture to the concrete envelope. At the lower end of the structure, a geometric iron cross made of metal profiles defines the boundary of the space. This element, along with the crushed brick, exposed reinforcement bars, and existing foundation, originates from the previous chapel, which was built in the same orientation and scale.

 

Through this reuse, the project by S-AR Studio operates as a continuation rather than a replacement. Materials from the earlier structure are reassembled into a new configuration, allowing the chapel to retain traces of its former presence. The result is a compact architectural intervention that integrates memory, material, and site into a single, continuous form.
