Building between partitions with ground floor and two landings. It presents a symmetrical façade with a vertical outline, this one accentuated by the size and the format of the openings, in parabolic arches that connect in an upward direction until ending in stepped gables in the first place and in an arch at the top.
The ground floor has two parabolic arches with buttressed sandstone reliefs. The first floor has an iron balcony and moulded cement profiles in the arches. The second floor has the same layout and balconies. It presents the cornice crowning that follows the gables.
The façade has a stone plinth and the rest is plastered in grey. The interior floor is divided into two areas divided by a monumental staircase. The floors are walled with a typical Catalan vault support by iron beams. The back of the first floor, which is under the roof, is covered by a brick vault supported by braces. The third floor, only partially built, has a crystal skylight shaped like saw teeth. The carpentry and forging work should be highlighted.
It is a very representative example of Muncunill's adaptation of the classic type of house to turn it into an industrial building without the need to alter the image of the city. It participates in the most typical stylistic currents of the moment.
It was built at the request of Joaquim Alegre and was a textile warehouse until it was abandoned. Finally, the property passed to a real estate agency in Barcelona. The defunct "Grup d'Arquitectes de Terrassa" had a brilliant and efficient action to save the building from destruction. Later, at the end of the 1970s, it was acquired by Manuel Tobella i Marcet to install the archive that bears his name – a foundation dedicated to the city where a series of private collections are already of public use of photography, programmes and local brochures, in addition to various documentation. The entity is governed by a board, has a staff, library and organises cultural activities and publishes works of local interest.
