Living Architecture

From its origins linked to social assistance, through its key role in the modernisation of telecommunications, to its transformation into a prestigious residential and administrative building, the property has continuously adapted to the needs of each era without losing its essence. The architectural vision of Ramón Cortázar, his ability to integrate advanced technology with elegant design, and the enduring construction quality make this building one of the city’s most iconic landmarks. More than just a building, it is a living legacy that continues to add value, character and authenticity to the heart of Donostia.

A social legacy

The building located at 29 San Martzial Street in Donostia–San Sebastián stands as a true symbol of the city’s urban, social and technological evolution. Originally, the corner it occupies today was dedicated to social welfare services, housing the San José Children’s Asylum from 1891, promoted by local charitable initiatives. It later became a first-aid centre and the headquarters of a graded school, reaffirming its role as a space at the service of the community until approximately 1925. This initial period reflects the era’s sensitivity towards social welfare and community development. However, the most significant transformation came with the creation of the Municipal Telephone Exchange, inaugurated in 1909, which drove the city’s technological modernisation and positioned the building as a strategic infrastructure within Donostia’s communications network. From 1970 onwards, the property began its transition to residential and administrative uses, while maintaining its prominent presence in the heart of the city.

An urban landmark

Naturally integrated into a strategic location within Donostia’s city expansion area, the building is surrounded by highly significant landmarks such as Banco Guipuzcoano, San Martín Market and the former Bellas Artes Cinema. Its presence reinforces the area’s visual and stylistic continuity, enhancing the classic and elegant character of the city centre. The pedestrianisation of San Martzial Street in the late 1990s and early 2000s significantly increased its visibility, turning it into a reference point for residents, businesses and visitors alike. Today, the building remains a valuable real estate asset, not only due to its prime location, but also for its ability to bring character and prestige to the urban environment.
