The documentation that describes the connection of materials.

The application of details in interior design refers to the design of the many smaller elements in a project. For some designers, it is the connections between materials, for others, it is the addition of elements like pattern and textiles that enhance a design. Details are the ways in which an interior comes together in a cohesive way.

Designers are tasked with communicating the design of details to fabricators and contractors, indicating how materials join, and explaining the tolerances—the level of precision in measurement—that are expected on the project. These subtle decisions are not immediately noticeable to a user or occupant, but if implemented well, they will be revealed over time. Attention to details also allows designers to use objects in unexpected ways, such as designing a custom shape on a plaster wall, or innovatively using materials to elevate a design.

To have a final design come together comprehensively, a lot of time, care, and effort needs to be given to coordinating the development of the space, from drawings through to the built form.

These are some of the elements in a design that require the use of details

Technical

Elements that make the fabrication of a design possible. Wall types and assemblies, millwork and joinery methods, standard heights and dimensions of objects, openings and material use (built-up floors), lighting integration, doors and transitions between material.

Aesthetic

Elements that enhance the visual and tactile appeal of a space. Tile and floor patterns, upholstery types, window coverings, surface types, opacity of materials, reflective elements, feature lighting elements.

Accessories

Items that are not integral to a solution. Choices of furniture, artwork, books, and other objects that fall into the realm of decoration; certain types of lighting to emphasize the details of a space.
