After the end of the war, Prishtina began to be built in every part. The city changed its earlier appearance, taking on a new, attractive look for citizens, but this brought development problems. The urban and architectural transformation can be defined as a change in the city's physical and social condition. Each object transforms a part of the city from its initial state to a new appearance. Over 20 years, Prishtina transformed from buildings built during socialist periods to a modern city. However, not every transformation was appropriate or well-designed, influenced by political, historical, and demographic changes.

The city's current state is seen as an informal phenomenon. "Informal" in architecture refers to poor development, impacting the quality and life of citizens. Factors leading to this informality include unplanned investments, superstructures, unauthorized constructions, lack of architectural plans, low professional work, and post-war demographic growth. Rezoning spaces incorrectly and citizens' attitudes towards the city also contribute to this informality. Prishtina was built quickly, lacking a distinct architectural style, and faces issues due to disregarding plans and prioritizing private interests.

Informal architecture in Pristina was led by influential people with limited architectural knowledge. This issue was not unique to Pristina but also present in other Balkan cities like Tirana, Podgorica, Belgrade, Sarajevo, Skopje, etc. These cities shared a similar development history and architectural perception.

The informal development was challenging for relevant institutions in Pristina post-war, overwhelmed by new developments, population growth, and lack of plans and architects. The approach to architecture in Pristina today mirrors the post-war period. Economic challenges contribute to the city's urban and architectural destiny.

The Vienna Declaration, signed in March 2005, addressed informal settlements in the Western Balkans, including Pristina. Objectives included regulating informal constructions, ensuring equal living standards, and integrating informal settlements into the social, economic, and legal framework. The declaration aimed to improve living and working conditions equitably and sustainably.

Other meetings in Pristina, organized by international bodies like Un-Habitat, Unmiku, and OSCE, discussed informality and aimed to raise awareness about city construction. In the first decade after the Kosovo war, informal settlements grew rapidly, often without proper plans or documentation, and were built ad-hoc by landowners. These neighborhoods represented economic growth but negatively impacted city planning. Private investors and residents were encouraged to improve city conditions.

Informality in Pristina is also linked to poor economic development, especially post-war. Not all informal settlements were poor; some resulted from land speculation and irresponsible property development. Throughout the 20th century, political influences affected Pristina's architectural and urban planning, making it a secondary concern.
