About r/InteriorDesign
In its own words:
Interior Design is the art and science of understanding people's behavior to create functional spaces within a building. It is a multi-faceted profession in which creative and technical solutions are applied within a structure to achieve a built interior environment.
Community guide
r/InteriorDesign (#924, about 1.2 million) treats interior design as spatial problem-solving—behaviour, function, built environment—not pure décor mood boards.
What belongs
Design-minded interiors (about 36 posts/day; gallery-heavy). Rules stress design over mere decoration, starting with your own ideas, minimum standards, no self-promo, and no link shorteners.
Versus interiordecorating
interiordecorating explicitly welcomes DIY décor styles and moods. InteriorDesign wants functional design thinking inside the structure.
Practical pointers
Show your concept, not only a shopping wishlist; avoid shorteners.
