Our history


Our first activities in the construction sector date back to 1983 and the creation of Batimelec. Initially active in the general electrical field, the business gradually evolved into a general contracting company.


In 1991 we created the company ACI, entirely dedicated to renovating and developing office areas.


In 2013, 1 SPACE DESIGN was founded, overseeing all our work designing and renovating professional spaces. The 1 SPACE DESIGN brand reinforces the company’s dual positioning: we not only take charge of the project’s execution, but we also work with our own architects who create the designs, draw up the plans and guarantee you a workspace that meets your expectations.


In 2014 we acquired GMTF to meet our customers’ heating, ventilation and air conditioning needs. We can offer a full range of services, from the initial plans to the finishing.
