Continuous ventilated facade for two single-family homes in Spain

Located in the municipality of Camargo, Spain, this development of two semi-detached single-family homes designed by MMIT arquitectos is conceived as a compact volume with clean lines and controlled proportions. The project is designed to perform efficiently in an Atlantic climate characterized by high humidity and frequent rainfall. The volumetric and facade treatment allows the two homes to be perceived as a single architectural piece, coherent and unified.

On the east, west, and south elevations, the continuous envelope is resolved through vertical panels and large framed openings, reinforcing the reading of a compact volume. The joint layout and the proportions of the openings highlight the facade modulation strategy and the direct relationship between the composition of the exterior elevations and the internal organization of the program in both homes.

The exterior envelope is executed as a ventilated facade clad in Neolith Pietra di Piombo with a Riverwashed finish. This model acts as the continuous skin of the volume, while Neolith Nero in a Satin finish is used on selected ground-floor areas, introducing a subtle tonal variation that helps define the building’s base without altering the unified perception of the whole. The modulation has been carefully developed so that the panels align with the overall composition, with a reduced number of joints and a clear, orderly reading of all facades.

Each home is organized longitudinally across three main levels: ground floor, first floor, and roof. The ground floor accommodates the daytime living spaces and areas most closely connected to the entrance and the garden, while the first-floor groups the nighttime spaces with a symmetrical layout around the vertical circulation core of each dwelling. Above, the roof is conceived as a technical level and an outdoor living area, maintaining continuity with the longitudinal character of the volume. This internal structure is clearly visible on the ground floor, first floor, and roof plans, all of which are coordinated with the modulation of openings and facade panels.

The choice of Neolith is also driven by its wide range of finishes that can be combined with one another. This aspect has been key in fine-tuning the tone of each facade plane while maintaining a consistent identity throughout the residential complex.

“We chose Neolith for the possibility of using large formats and for the great compositional flexibility it offers. Another decisive factor was the wide availability of finishes that complement each other.”

For the installation of the ventilated facade, the Neolith HC system was selected. The system is based on an aluminum substructure composed of brackets and vertical profiles anchored to the load-bearing wall. Neolith slabs are installed onto this structure using double-sided tape for initial positioning and a structural adhesive for final fixation.

By working with 6+ mm panels, the HC system allows for a reduction in self-weight and an optimization of loads on the building. This is particularly advantageous in residential projects, where a lightweight envelope provides benefits during construction as well as in the overall performance of the housing complex. The fixation remains concealed, promoting a continuous appearance of the Neolith surfaces and avoiding visible elements that could interfere with the reading of the facade.

“Durability and ease of maintenance have been among the most valued characteristics for both the client and our team.”

The ventilated air cavity, combined with thermal insulation and the system’s airtightness, improves the energy performance of the complex and contributes to a high level of indoor comfort throughout the year. This results in reduced temperature fluctuations and improved humidity management.

In this project, the Neolith surfaces incorporate an advanced treatment applied to the slabs which, when activated by light, triggers a photocatalytic process. Through this effect, certain pollutants present in the air and on the facade surface are transformed into less aggressive substances that are easier to remove.

In addition, this treatment alters surface tension so that water spreads as a continuous film rather than forming droplets. This behavior allows rainwater to carry away dirt more effectively, helping the facade remain clean for longer periods and significantly reducing maintenance operations. In an Atlantic environment like Camargo, with consistently high humidity, this performance is particularly relevant for preserving the original appearance of the residential complex over time.

One of the key factors in choosing Neolith was the ability to work with large formats and a catalog of finishes designed to complement each other. In these homes, the combination of Neolith Pietra di Piombo and Neolith Nero makes it possible to fine-tune the tone and presence of each facade plane while maintaining coherence in the overall image. This interplay of tonalities reinforces the volumetric expression and supports integration with the rest of the envelope materials.

“Its versatility and flexibility when it comes to combining finishes make it a highly desirable material.”

The project was developed based on specific conditions that required targeted solutions: connections with the terrain, protection against rain and wind, solar control, and the need to preserve views. Thanks to its format, durability, and flexibility in modulation, Neolith has made it possible to address each of these requirements while maintaining a sober, precise, and long-lasting envelope.
