This master thesis deals with the renovation of the Miklošič park park in Ljubljana, which is one of the most important parks in the city centre and together with buildings it represents the heart of unified art nouveau space, but its today image is degraded. The thesis examines the emergence and development of Miklošič park and its context in all scales. After carrying out the analyses and through the creative process, the thesis draws up a plan for renovation of Miklošič park, where design decisions are justified from the perspective of the development of the park and a contemporary view on a role of public space today, as a place for living and socializing. In designing process the thesis identifies the space as a city plane, where two entities are manifested: a square and a park, as historical resources reveal that Miklošič park was first designed as former, but was later implemented as the latter, which is still its image today. In search for a renovation plan, the thesis strives for a refined art form, which seeks inspiration from art nouveau designs. The thesis delivers three variants for the renovation of Miklošič park and each of them represents a unique space with new added qualities. With elemental shapes a new designed park becomes a place with added monumentality, directed into the future.
