Samples allow materials and finishes to be studied before they are used throughout a project. The project’s finish schedule records what has been specified, while the approved sample provides a physical reference for color, texture, and overall quality. Manufactured products should resemble the approved sample closely. Natural stone, handmade tile, and wood carry more variation, so a sample represents the intended character rather than an exact match. For custom finishes such as stained wood, plaster, or metal patina, an approved sample establishes the standard for the completed work.

Mockups move the conversation from material selection to spatial experience. They can be used to study proportion, alignment, material transitions, and the way a detail will be constructed. The most useful mockups often focus on intersections at a corner, threshold, window opening, or the point where a wall meets the floor. These conditions show how the architecture will come together in ways that may be difficult to understand through drawings alone. Mockups can also make scale easier to judge. On one project, a full-size model of a custom stone tub allowed the client to experience its dimensions within the room and decide that it should be enlarged before the final stone was carved.

Samples and mockups give clients, designers, fabricators, and contractors the same physical reference. They help clarify expectations, resolve construction questions, and support more accurate planning before work moves forward. By testing important decisions early, the project team can make thoughtful adjustments while change is still possible helping the finished space reflect both the design intent and the quality established throughout the process.
