The urban project at number 37 San Francisco street in Tolosa has had a controversial trajectory spanning several years. A detailed chronology shows how plans have evolved and controversies have arisen.

It all began in June 2022 with the initial approval of the original project, which planned the demolition of the Sagrado Corazón villa and the construction of two new buildings.

The process was suspended in January 2023 when Áncora requested the villa be declared a cultural asset. In May 2023, the Ararteko also recommended protecting the villa as Basque cultural heritage.

In February 2024, under the new EH Bildu government, the Sagrado Corazón villa was included in the Municipal Catalogue and protected.

In May 2024, a Modification of the Detailed Study, carried out by the developer, was approved. This new project maintains the villa but contemplates the construction of a single, taller building instead of the two originally planned.

The residents' association, with the assistance of an urban planner lawyer, filed objections, arguing that the new building violates municipal regulations regarding heights, buildability, and alignments, and that the Detailed Study does not permit a change in land use.

In October 2024, the City Council dismissed the objections and approved the new urban project in a plenary session. Subsequently, in April 2025, the residents filed a lawsuit before the TSJPV.

In May 2025, residents of portal 39-A warned of the "risk" the City Council ran if it granted the building permit, considering that a favorable court ruling could lead to the demolition of what had been built.

In September 2025, the full building permit was granted, and work began. Finally, in March 2026, the TSJPV ruled in favor of the City Council, determining that the Study was the appropriate instrument.
