Case study in Malang city, IndonesiaMalang is a city with a strong heritage of Dutch buildings. The Kayutangan Street corridor is a commercial building streetscape that is one of the prides of Malang city. Through development that respects the historic environment, it is possible to create a streetscape of commercial buildings that contributes to the visual corridor. Recently, however, the uncontrolled development of new commercial buildings has brought about major changes in the city streetscape. Weak building-control regulations for conservation areas cause degradation in urban streetscape quality. This paper aims to investigate the growth characteristics of the existing streetscape of commercial buildings in Malang city by comparing case studies of buildings in the conservation area streetscape with the new streetscape corridor. A field survey method is combined with a people preference method to compare building owners' judgment regarding the streetscape characteristics of commercial buildings. The results of both approaches will be categorized and compared based on visual characteristics. This paper also clarifies the opinions of building owners regarding the quality of streetscape visuals and investigates the role building owners play in the formation and alteration of the commercial streetscape. Today, the corridor's historic buildings are gradually being replaced by new buildings due to a lack of strong regulations in

The rapid, uncontrolled development of the new commercial street corridor has created a city streetscape that is intended to be of economic interest with little regard for structuring a quality visual space. Reflecting on the historical urban space could be a useful basis for planning and designing better cities in the future.According to Nasar (1998) 11) , as cited in Rapoport (1993), good city planning requires a study that involves a group of people in a particular area in the process of determining a prominent feature in the built environment.There are many studies related to the preservation of historical streetscapes and the formation process of it in Japan. Watanabe (1982) 19) and Nishimura (1991) 12)15)19) conducted a major research investigating historic environments all over the country. Nishimura clarified the situation of design review by ordinance to control townscapes in local cities. Moreover, he marshaled arguments for historic preservation in foreign *Doctoral student,
