Sustainable streetscape design considers several aspects, namely environment, architectural, economic and social. One aspect of streetscape design is the ecological aspect. This research aims to analyse user’s preferences for implementing ecological aspects in streetscapes’ design, thereby increasing ecosystem balance and minimizing negative impacts on the environment. This research uses quantitative methods. The research was carried out in the center of Medan City. Several variables used in the ecological aspect are the availability of open space, facade, vegetation, street furniture, and drainage. Data collection was carried out by distributing questionnaires to people in Medan City, and the analysis used is descriptive. The research results show that green open spaces should be easily accessible and connected to sidewalks. The building facade provides an attractive visual impression. Vegetation on pedestrian paths can provide a sense of comfort for pedestrians. The provision of street furniture on the sidewalk should be in an attractive form and provide a feeling of comfort for users. Drainage is needed to handle rainwater runoff so that flooding can be prevented. The streetscape design concept was prepared with the application of ecological aspects that could support a green city. Providing a comfortable and attractive streetscape can increase walkability in a city. Keywords Architecture, Ecological Aspect, Green City, Streetscape, Urban Design 1. Introduction Streetscape is an element of the urban environment that represents the design of street and visual quality [1]. Streetscape consists of buildings, road surfaces, bus stops, signage, street furniture, rainwater runoff and etc. There are five elements of streetscape: increasing air quality, minimizing the effects of heat island, enhancing water quality (including flood management), improving energy efficiency, and lowering light pollution [1]. Sustainable streetscape has some aspects such as functional, ecological, social, and economic [2]. The ecological aspect consists of roads as part of a green infrastructure network (in which there is vegetation and open space), carrying flora and fauna and managing rainwater. The amount of vegetation has a different relationship with walking activity in different land use types [3]. This research aims to analyze people's preferences for implementing ecological aspects in streetscapes' design. The streetscape design concept is
