The Assembly Hall of the Hernani Town Hall in Gipuzkoa, Spain, is an architectural gem from the late 19th century. It is part of a noble ensemble that includes a grand imperial staircase, the plenary hall, and the assembly hall itself. This latter space, covering 155 square meters and measuring 25 x 6.2 meters, was originally conceived as a venue for social events, dances, and celebrations.
The assembly hall was recently rehabilitated by Spanish architectural firm BARRU ARKITEKTURA SLP to preserve its aesthetic, heritage, and functional value. The hall features one long side with five large windows overlooking the town square, with a central balcony that serves as the focal point of the façade. Inside, the hall is symmetrically arranged, with a Serliana framing the central opening of the façade and two additional Serlianas marking the thresholds to the lateral spaces.
Over the years, the hall underwent various modifications that altered its original decor, leaving it in a state that did not meet contemporary comfort standards. The mural paintings, which originally replicated marble, had been lost due to poor-quality interventions. A historical photograph showing the architect and the master builder in the newly completed hall was a valuable reference for the restoration.
The first phase of the intervention included the installation of an air conditioning system with ducts and vents in the wooden floor, a new lighting system controlled by radiofrequency to avoid damaging the moldings, the replacement of deteriorated carpentry, and the complete repainting of the hall. Additionally, the original wallpaper was restored.
One remaining challenge was the placement of the secretary’s desk, which needed to be integrated without altering the overall layout of the hall. The solution was a curvilinear piece of furniture with a minimalist stainless steel champagne-colored finish that, when viewed from the center of the hall, appears almost imperceptible. This piece opens towards the circulation area with oblique and curved geometric forms, including an oculus in the ceiling, creating a workspace that offers light, comfort, and privacy.
The intervention was respectful and sustainable, designed to be reversible without altering the heritage character of the hall. Special attention was paid to lighting and acoustics, using noble and removable materials. The new element, though distinct, integrates with the original space, respecting its essence while adding a contemporary language.
