Sienit Group made its start-up back in 1994 with the establishment of the first of the companies – Sienit Ltd. Initially, the company focused on the development of residential projects supplying the demand of the construction services market in that period. A major drive on the business track of the company proved to be the emergence of the first foreign ‘on green’ investments of Ferrero Germany, Miroglio Italy, Liebherr Germany and Socotab Switzerland. Following the effectuation of these and projects for the course of 1996-2003, Sienit lived up to a substantial experience in the industrial engineering coining a name for itself as a trusted and reliable business partner.

Having seen its business expanded and its building services differentiated into separate companies, the company assumed its holding structure, notably Sienit Holding which was to integrate and make the best of the processes of a comprehensive implementation of investment projects.

After a profound analysis of the difficulties for the investors of ‘on green’ industrial projects the wheels of industrial zone development were put in the motion aiming at providing for a plain sailing of investment projects effectuation. Sienit Holding created the first industrial zones in Bulgaria –"Maritza" Industrial & Commercial Zone and "Rakovski" Industrial Zone, which in seven years’ time have proven to be the home of ca. € 1 billion investments.

Now that the business has developed and expanded, the companies of the group got involved in the construction of landmark projects in Plovdiv, prominent infrastructure and environmental projects in the country. In 2012, Sienit Holding built the largest PV park in Bulgaria.

2013 stands out for the involvement of Sienit Holding in thus-far largest-scale project, notably Trakia Economic Zone. This project was set to pool in all industrial areas in the vicinity of Plovdiv for the purposes of enhancing the services provided to local and foreign investors. Trakia Economic Zone provides over 7 million square meters land to supply investors` investment demand.

Along its 20 years of track record, Sienit Holding has developed upward of 140 projects – industrial, residential, commercial and administrative, over the aggregate area of 1.7 00 000 million square meters, plus over 80 infrastructure assignments.
