Casa Müller is a project designed by Void Studio. Built in the early 20th century by the Müller Stellmann couple, the walls of this house hold the sun of over a hundred years of sunsets; its windows, the progression of the history of the north of the country, and the interior, the grandeur of a family that had fallen into oblivion.

After the death of its last heirs, furniture, lamps, books, and personal objects remained as if waiting for the return of its former inhabitants. But no one ever knocked on the door again. As with many other buildings in the historic center of Chihuahua, time passed over this one and it became abandoned, obscuring the splendor of its ceilings with cloth skies, checkerboard floors specially designed for its main hall, and the crimson red facade. Ceilings fell, windows were vandalized, and with the collapse of one of its walls, the property was looted and turned into a hotbed of social problems.
Its location, on the corner of 4th Street and José Esteban Coronado, a block from the Gameros Mansion and in a straight line with the Chihuahua Metropolitan Cathedral, gives it great architectural importance, but even more substantially, urban importance. And it is from the understanding of this relevance that the architectural firm Void Studio proposes a project that breathes new life into the house.
With the clear mission of rehabilitating the property and generating a positive impact on the area, the owner contacted the architecture studio and gave them carte blanche to work. In response, Void proposed a project that preserves and adapts the original structure to a layout that allows for new dynamics, while respecting the beauty of the house and highlighting its different construction stages.
Of the two original courtyards, only one would be preserved, around which three independent spaces would be organized: offices, a bakery, and a space for events – specifically, Sotol tastings.
From the street, the view of the central courtyard is relatively closed by the white angles of a staircase, an almost sculptural element that has become the insignia of Void Studio. The staircase leads to a terrace that opens up the upper floor and takes advantage of the panorama of domes that flourish around. In order to accommodate these new functions, access and services were replanned.
During the execution of the project, the phases and styles of the house were revealed. The oldest structure in the adobe of the traditional mining style, an addition with a French flavor in the space of the octagonal corner, possibly from the Porfiriato era, and, around the 1940s, the incorporation of arched doors and windows with ornate ironwork.
Fulfilling the idea of honoring the passage of time, witnesses to its history are preserved at different points. In the bakery area, remnants of the original wallpaper, the windows, and the checkerboard floor with a peculiar two-radius design – devised and produced in Mr. Enrique Müller’s terrazzo factory – were rescued; but it was also decided to leave some fragments of exposed brick and the marks of the supports of the cloth ceilings.
The use of the beam system was respected, and although none of the ceilings could be saved, the walls were maintained and cared for with the selection of coffered ceilings that reduce the weight. In cases where the adobe was left exposed, it was treated with a sealant that protects it and allows it to breathe; in cases where it was covered, the option was to superimpose Tablaroca walls.
In the office, the second skin of the wall does not reach the ceiling and is made explicit with a line of light that shoots towards the old textures.
