The Linear City concept in spatial planning has been present since Soria y Mata’s proposal in 1882 (Collins, 1959). Yet, naturally conditioned elongated urban developments have not been a frequent subject of research. However, dynamic urbanization under ongoing processes of globalization have brought new conditions and challenges for cities, among them a strong impact of international financial markets on a city space. Cultural and recreational areas are being systematically replaced by commercial and office buildings what disrupts correct city structure. The set of conditions mentioned above relate to linear cities as well.
Apart from analyzing possible causes of developing existing linear cities, this paper aims to examine their contemporary development possibilities determined by mentioned above factors. Sarajevo, BiH serves as case example. On the basic of extensive literature review the development possibilities have been recognized. In case of Sarajevo possible interventions appear as strengthening main transportation axes and establishing new centers along the city spine1.

Contemporary housing attempts to help people and families meet their aspirations and social needs. A dwelling and housing estate should provide neighbourhood ties, privacy, contact, and cooperation. The housing environment also manifests the values and personality of residents: living style expresses the relationship between humans and culture. The paper aims to 1) describe the most important trends that have emerged in housing architecture in the 21st century and 2) identify factors influencing housing architecture in Poland and indicate which types promote and hamper the implementation of innovative design features. Awareness of the phenomena and processes occurring in housing and design can help better shape the development of housing environments towards sustainability.

Linear megastructures, apart from megastructures in general, are one of several types of concepts in context of linear urban development. The term refers to various compact architectural, infrastructural and transportation plans in linear form. With their daunting massive scale these concepts are often attributed to utopian attempts of pursuing an ideal city and therefore doomed to remain unrealized. This paper examines several models created throughout the course of history in terms of their emergence motivation, socio-economic circumstances and relation to urban sustainability. Through the analysis, it is argued that linear megastructures are often unjustly rejected without acknowledgement of their underlying beneficial features in terms of mitigating challenges to sustainable urban development.
