When the proper approach and scope becomes more solid, the design is refined and detailed plans are developed. Layout plans and elevations are finalized to define the spatial organization. Materials, finishes, and color schemes are selected to create a cohesive aesthetic. Coordination with structural, mechanical, and electrical engineers ensures that all technical aspects are integrated into the design. Detailed furniture, fixtures, and equipment (FF&E) plans are developed, and more detailed 3D models and renderings are created to provide a comprehensive understanding of the design.
