La Roca del Vallès town hall

La Roca del Vallès town hall is the seat of local government in a small town in the Vallès Oriental district, roughly 30 km north of Barcelona. Known locally as Can Sol, the building stands out from typical administrative architecture: it is a former garden-city style villa set in its own grounds, accompanied by outbuildings sharing the same decorative design.

What makes this building interesting?

Can Sol was built in 1920 to a design by architect Lluís Planas i Calvet. It is a freestanding building of ground floor plus two upper storeys, erected during a period when the town was expanding along a linear axis leading out from the old centre — the earliest chalets of the century appeared here, forming a new garden-suburb neighbourhood on the edge of the historic core. The garden still holds its original outbuildings, a gatehouse and a garage, both designed in the same decorative style as the main house, so the whole ensemble reads as a coherent piece of early 20th-century architecture rather than a stand-alone office block.

The building is listed in Catalonia's Inventory of Architectural Heritage, recognised as a representative example of the villa-style development that shaped the town during its early 20th-century expansion. After years of use it underwent restoration and today fully serves as the seat of the town hall, hosting council sessions and the local administration's day-to-day work.

How do you get to La Roca del Vallès?

The town sits right by the AP-7 motorway, making the drive from Barcelona about 30–40 minutes — a convenient option if you're exploring Vallès Oriental by car or rental vehicle. Regional buses also connect La Roca del Vallès with Granollers and other towns in the district, a practical choice if you're travelling without a car. The town hall itself stands in the central part of town, within the area developed in the early 20th century, so it's an easy walk from the surrounding streets once you arrive.

What will you see on site?

The façade of Can Sol still carries the character of a bourgeois residence rather than a purpose-built office: the proportions, decorative details, and garden layout make clear this was originally a private villa, not an administrative headquarters. That contrast with the plainer municipal buildings typical of the region is part of what makes it worth a look. Pay attention to the whole ensemble — beyond the main house, the smaller garden outbuildings are still visible, giving a fuller sense of the original 1920 design. Visits are limited to the exterior, since the interior is an active municipal office.

When is the best time to visit?

The best time to see the building is during weekday office hours, when you can freely view the façade and garden from outside without disruption. Spring and autumn are the most pleasant seasons in this part of Catalonia, with mild temperatures well suited to walking around town. In summer, aim for the morning hours to avoid the highest temperatures typical of Vallès Oriental.
