about M&J Group

We are one of the most modern companies specializing in the construction of customized industrial halls.

Most of our investments are conducted in the Design and Build system, which means that we go step by step with the Investor through the whole investment process, starting from assistance in finding a plot, official formalities, and the design process up to the construction and commissioning.

We are the Authorized Representative of Astron, the European leader in the field of prefabricated steel halls. Astron steel halls provide unlimited construction possibilities, which enables the creation of buildings of the dreams. No matter what is the purpose of the building, it is always tailored to the needs of the clients.

There are no impossible things for us, only those we have not done yet.
