PUTTING IT ALL TOGETHER—A SAMPLE PROJECT

Meet Lily and Chen. Their bathroom remodeling project is an example of how to prepare a design program. We interviewed Lily and Chen at their home. We used the various forms and checklists from chapter 5, "Assessing Needs," to collect information for their design project. Then, we developed this design program.

After you read the design program, look at one of the designs that were prepared for Lily and Chen. Do you think the design meets their needs? Is the design solution functional, safe, and convenient? Use the Bathroom Planning Checklists (Table 10.3 and Table 10.4) to evaluate the plan.

This sample design program focuses on space planning, the emphasis in this book. If you were developing a design program, you will give more attention to color, style, and visual impact.

aids in the future (Figure 10.13). In the existing bathroom, the toilet compartment may be limiting to accessibility. The door to the toilet compartment and access to the closet create a bottleneck in front of the vanity, especially in the morning. The jetted tub is seldom used, and can be removed to provide space for a larger shower. Only one vanity is needed in the bathroom, as a second vanity is going to be put into the adjoining bedroom. Storage is limited in the bathroom.

In their remodeled bathroom, Lily and Chen would like a large, accessible shower, more space around the toilet, a single vanity, water-efficient plumbing fixtures and fittings, improved traffic flow, generous storage, natural light, easy maintenance, and traditional, but simple styling. Lily and Chen want to emphasize sustainability in the choice of prod­ucts for the bathroom project.

Scope of the Project

The designer will:

• Develop a design that meets the client needs

• Select all fixtures, fittings, and finish materials, considering the priorities of accessibility and sustainability

• Prepare drawings and specifications for completion of the project

• Supervise construction and installation of the project

Objectives and Priorities

• Design a shower that is large enough to use with a mobility aid

• Design an open toilet area that would meet accessibility for a mobility aid if needed in the future

• Provide at least one tall cabinet with generous storage for towels, grooming products, and medicines

• Improve traffic flow to the closet by moving the adjacent vanity and enlarging the door

• Allow a turning circle of 60 inches (1524 mm) in the bathroom

• Design a vanity area with open access space below the lavatory for seated use

• Specify a window in the exterior wall

• Select easy maintenance materials that resist moisture and are simple to clean

• Specify water-efficient plumbing fixtures and fittings, including choosing WaterSense® certified products where available

• Specify sustainable products that are certified to meet standards to the material, including using recycled materials if possible

• Specify materials and products with traditional, but simple styling

Activities and Relationships

A user analysis was prepared for Lily’s and Chen’s remodeling project, and is presented in Table 10.5.
