A short, curated guide — not an automatic related dump. Figures come from SubMouse's safe-for-work directory when we have them.
r/architecture (about 2.1M members, directory rank #536) is for students, professionals and lovers of architecture. Interior spaces, renovation how-tos and historic houses each fit better when the interest is not architectural design.
Stay on architecture for buildings, theory and the profession. Use InteriorDesign for interiors, HomeImprovement for renovation projects, and centuryhomes for 100+ year-old houses.
