Following a bachelor’s degree in Architecture in Wuppertal, Germany, Hristiyana worked in Sofia, participating in the planing of various big scale projects.
Back in Germany, she graduated her master’s degree in Architecture at TU Berlin, focusing on urban planning of "Smart Cities" - intelligent, sustainable solutions and mobility systems in the city, participating also in a number of competitions and exhibitions.
Since 2015 she is part of an architectural office based in Tel Aviv, specialising in architecture, urban planning, interior and product design. Continuing her activity in the field of urban planning she participates and wins competitions such as Zion Square, Jerusalem, Hiriya Recycling Park and the iconic building in the lake of Ramat Gan National Park.
In 2017 she decided to follow her dream of designing a big-scale project that would upgrade the city of Sofia and set it as one of Europe’s modern green and sustainable cities. Together with architect Svetoslav Alexandrov, she founded the NPO GreenLineSofia, with the goal to revive old abandoned railways and turn them into a 32km long bicycle and pedestrian lane circling the city, connecting all parts of it, offering various development opportunities.
