The founders of HANN Development have been an active part of the family business so far – and have also managed to put that experience to work on their own.


The quality of the materials we use, as well as keeping up with the rapid technological developments in the construction field have been our guiding lines through the years.


The vast majority of our mother-company’s portfolio is comprised of residential units, as these are the most sought-after in developing markets, especially in times of flourishing economy.


Although most of our projects are located in Turkey, Romania has already been a target for our expansion, given its solid growth potential in terms of housing.
