You could customize ibuffer with a filter group that groups by buffer
directory.  Something like this, from
https://emacs.stackexchange.com/questions/10621/how-to-get-ibuffer-to-use-directory-tree-as-filter-groups/17731#17731
(you can test it by pressing / D in ibuffer):

(defun get-all-buffer-directories ()
  "Return a list of all directories that have at least one file
being visited."
  (interactive)
  (let (l)
    (dolist (e (sort (mapcar 'file-name-directory
                             (cl-remove-if-not 'identity
                                               (mapcar 'buffer-file-name
                                                       (buffer-list))))
                     'string<))
      (unless (string= (car l) e)
        (setq l (cons e l))))
    l))

(defun ibuffer-set-filter-groups-by-directory ()
  "Set the current filter groups to filter by directory."
  (interactive)
  (setq ibuffer-filter-groups
        (mapcar (lambda (dir)
                  (cons (format "%s" dir) `((directory . ,dir))))
                (get-all-buffer-directories)))
  (ibuffer-update nil t))

(define-key ibuffer-mode-map
            (kbd "/ D") 'ibuffer-set-filter-groups-by-directory)
