Permanent fixtures to walls are generally departmental items.
If you wish to have other sizable items fixed to your office wall please first contact email@example.com who can review the request and fit the item to ensure appropriate fittings are used for the particular wall area (as some wall areas have patrising and others do not and the wrong fittings could result in the item falling off the wall or tearing sections of the wall surface away).
Odd smaller items such as the odd picture may be attached to the wall, e.g. with a small nail. If you would like assistance to hang a picture etc please contact firstname.lastname@example.org
No decoration, personal items or signage should be installed in the communal areas of the building without first consulting email@example.com. In particular do not stick items to the outside of office doors (which can result in damage and uneven fading and discolouration) or to the corridor walls (where it can result in removal and discoloration of the pain).
The Department has an Art Committee which oversees art, display and decoration in the communal areas.
