What degree of social distancing is effective to minimise transmission indoors?

Reducing close face-to-face interactions can reduce risks, but there is no “safe” distance in most indoor environments which will eliminate the risk altogether. Evidence suggests that respiratory particles that carry virus can easily be carried in the air over 2m. (Visualising SARS-CoV-2 transmission routes and mitigations | The BMJ)

There is an increased risk of exposure when people are face to face at less than 1m distance. This is because the particles that are exhaled when breathing, coughing, or talking are much more concentrated in immediate breath. Designing the layout of rooms to minimise very close face to face interactions is likely to be beneficial for reducing risk.
