For many years, the facade of the "Singular" building has withstood various weather conditions. However, with the passage of time, it has suffered progressive deterioration, presenting problems with both water infiltration and thermal insulation. Due to its great height, when rainfall is intense and accompanied by strong winds, the water adheres to the brick, which causes leaks.[9]​.

The first solution proposed to remedy this problem was to paint the brick, a measure that, although it provided a temporary improvement, was insufficient in the long term. After five years, the water leaked again, evidencing the need for a more durable solution.

For this reason, a new strategy was proposed: the installation of a ventilated façade. The work was approved at the end of 2018 and was carried out by architects José Araujo Muñoz and Asier Oteiza, who worked to faithfully replicate the original appearance of the brick, respecting its color and the granulated texture of the ceramic. The new ceramic pieces incorporate a 10-centimeter layer of insulation to offer greater protection against inclement weather. In particular, fireproof rock wool was used, a highly resistant material, which is hidden behind the ceramic coating.[9]​.

The building is made up of three different parts: two for residential use and one for offices. Its design was conceived with the purpose of creating a small city integrated within these three structures, offering its residents various spaces for their use and enjoyment. These include a parking lot, a shopping center, a restaurant, a high-rise garden and a swimming pool, in addition to the homes and offices themselves. [6]​.

The building was erected on a series of pillars that allowed the ground floors to be kept open, facilitating their use as commercial spaces. These imposing concrete columns constitute a distinctive element that links the building to brutalist architecture. This architectural style is characterized by the use of raw concrete, with its rough texture and without coatings. Furthermore, brutalism usually incorporates large structural elements, such as the building's columns, which elevate its base above the commercial area. This configuration not only optimizes space, but also gives the complex a feeling of solidity and monumentality, representative features of this architectural trend.

Above the commercial area there is a community access area that simulates a plaza. To reach the homes, it is necessary to use two elevators: the first allows access to the mezzanine, which functions as an elevated plaza, while the second facilitates arrival to the different homes.[6]​.

Two of the towers that are destined for the residential area have a pentagonal floor plan and have fifteen floors, housing homes with three orientations. The third tower, lower in height compared to the previous ones, has a square layout and is intended for use as apartments and offices.[6]​.

On the eighth floor, the towers present a cut in their structure, leaving them free of housing and generating an open space. Initially, this area was conceived to house a garden for the use and enjoyment of residents.[6]​ This design shows the influence of the French architect Le Corbuiser, who innovated in modern architecture by incorporating gardens on the roofs of buildings, thus promoting the integration of nature in urban environments. Additionally, he promoted the construction of covered plazas, which were large open structures and floating covers to promote community life, regardless of the weather.

The building follows the modern functionalism that developed after the Second World War, with a design that makes use of reinforced concrete, steel and glass, characteristic materials of post-war reconstruction. Furthermore, its spatial layout responds to a rationalist logic, aligned with the architecture promoted by Le Corbuiser.[7]​.

The original project contemplated the construction of the tallest building in the region. However, in order not to interfere with air traffic at Noáin Airport, it was decided to reduce its height. Despite this modification, it is still the tallest building in Navarra, with a height of 70 meters.

Many of the stores located on the ground floor of the buildings ended up closing due to their low profitability. Currently, these commercial spaces have been converted into homes. An example of this is the old bar "El Plural", which closed approximately 18 years ago. The architect of the work, Óscar Vidaurre"), has managed to maintain the essence of the old establishment in the new home.[8]​.
