2021
Our company, Tetra Group Kft. was established in 2021 with the aim of providing high-quality services for the implementation of small- , medium- and large-scale construction projects in line with today's requirements.

2022
We have separated our design and construction activities and established Tetra Build Kft. to provide engineering services.

2024/I.
Our third company, Tetra Invest Kft., serves as the framework for our own investments and property developments. We have also started our own workshop and started manufacturing low voltage switchgear, distribution and control equipment.

2024/II.
The most important trend today is sustainability and the transition to green energy. In this spirit, we believe it is important to develop sustainable solutions right from the design stage. For this reason, we have significantly expanded our in-house design team, and a new acting managing director is overseeing the independent operation of the company.
