Preamble The District of Columbia has embarked on an ambitious city planning scheme to reshape the city scape to accommodate the younger generation interested in compact activity zone were shopping recreation and work all happen in close proximity. In part this phenomena is driven by the baby boomers who has a age factor that make living and entertainment in the close proximity a necessity of life. The options for boomers are suburban senior homes or an urban area with all the needed amenities within reach. Transportation access is also important for both groups. So the city Mixed Use (MU) … “zones are designed to provide facilities for housing, shopping, and business needs, including residential, office, service, and employment centers.†B. Program XYZ Corporation has acquired a 2.4 acre parcel of land on the Connecticut Ave corridor in North West Washington DC. (See subdivision record plat Appendix B). In partnership with the Giant Corp., the company intends to develop a mixed use building to include retail and office activities on the land in keeping with the Washington DC Connecticut Ave corridor urban plan. The project is envisioned to conform to the implementation of the Comprehensive Plan. II. PROJECT STATEMENT With the influx genXers, Milennials, and an establish population of professional and elderly people[footnoteRef:1] the XYZ Corporation has determined through market studies that this site will support a retail and office building. [1: ] XYZ Corporation recognizes the business advantage of locating its branch offices in close proximity to several Universities and on the metro red line. As a result the corporation has assembled a strategic parcel of land on Connecticut Ave NW adjacent to the Metro line. (See also Appendix B.) III. SITE AND ENVIRONMENTAL DATA A.

Introduction

The rapid evolution of urban planning and architectural design in Washington DC exemplifies the necessity for buildings that are not only functional but also harmonious with their surroundings. This project focuses on designing a mixed-use commercial and office building within the MU-7 zoning district, emphasizing compliance with city planning goals, zoning regulations, and technical requirements. The purpose is to create a building that meets economic, social, environmental, and regulatory considerations, addressing the needs of a diverse urban population and fostering sustainable growth.
