The design concept is result from long process analysis of various factors that can affect the strength, function, and beauty of a building. The design concept can also be said to be an answer to the design issue. An issue in a design context is about, a trend, a question, a topic, a proposition, or a situation where a building design demands to match the wishes of clients and users. In planning the SAMES Warehouse for Medical Equipment, Nutrition, Bulk Storage, Quality Assurance Laboratory and Fire Hydrant System Project , there are several design issues that are the focus of attention, such as functionality, modern, and ecology. Based on these three design issues, two approaches were chosen that were considered most capable of presenting an appropriate building design is modern architecture and the ecological architecture, which was formulated into Eco-Modern . b. Architectural Design Approaches and Concepts Design Approach Modern Architecture Modern architecture is a session in architectural development where space is the main object to be processed. If in the past, architecture was more concerned with how to process the facade, ornaments, and other aspects of a physical quality, in modern architecture, non-physical qualities are more important. The focus in modern architecture is how to come up with an idea of space, then process and elaborate it in such a way, until it is finally articulated in the preparation of real space elements. Form and Space in Modern Architecture The development of Modern Architecture includes the development of thinking about the concepts of form, space, function, and construction. Form Forms in Modern Architecture are not only determined and formed from functions and building materials used.
