Groups that have strong intergroup ties, or groups that would benefit from such ties, should preferably be located close each other. Interaction patterns may also influence the demand for social spaces such as coffee lounges. Members of very dense groups (groups with lots of internal ties) are more likely to need and use such spaces than loose groups (groups with few internal ties).
