Formed by several family generations dedicated to the art of construction, Units-4, S.L.U. was established in 1986, in the province of Barcelona, specifically in the town of Santa Coloma de Cervelló, where it still remains.

Santa Coloma de Cervelló is a few minutes far by road from the city of Barcelona, and it is a privileged emplacement due to its logistics communications.

Since the beginnings, in Units-4, S.L.U. we have always had as a main characteristic, the will to offer a professional, fast and efficient response to the demands of our clients in order to carry out the different building projects that they have entrusted us.

Over the years we have developed all types of works and constructive solutions, which enabled us to accumulate experience in a wide range of areas within the world of construction.
