Heliopolis 21 is an architecture and urban design office, currently involved in a large number of projects mainly regarding low energy public buildings like universities, concert and sportshalls, and sustainable tourism like “low impact-high comfort” resorts and hotels.

“In our projects we test the effects of the climate design for the future city.”
“We believe in radical and utopian design visions to better fit future well-being needs and in urban design as an open system tool.”
“We design environmental conscious buildings and smart cities to meet today’s needs without compromising the needs of the future generations.”
