What are the plans and specifications of interior materials used in private spaces called?

The plans and specifications for interior materials used in private spaces are referred to as Residential Interior Design. This term encompasses the comprehensive process of designing interiors specifically for residential environments, focusing on the functionality, aesthetics, and emotional impact of a space.

Residential Interior Design involves a detailed understanding of the client's needs and preferences, which informs the selection of materials, colors, furniture, and layout. It goes beyond simply choosing finishes; it integrates all aspects of the interior environment in a way that is personalized for the inhabitants.

In contrast, architectural design typically refers to the broader scope of designing buildings and structures, not solely the interiors. Space planning is more about the effective arrangement of spaces within the overall layout, while commercial design focuses on spaces utilized for business purposes, which involves different considerations than those for residential spaces. Thus, the correct term for defining the plans and specifications in this context is indeed Residential Interior Design.
