This planter box thread has a s 108 tone to it.
JT talks of not changing changing common property but add to, alter and erect are the terms used in s 108 and section 108is headed “Changes to the common property” (see below)
The minor improvements and cosmetic improvements sections only extent to owners not the OC itself.
“… then any additions to the common property for the purpose of improving or enhancing it must comply with the requirements of s 65A (now s 108). Glenquarry NSWSC
It sounds like complete overkill but it seems the Act requires a general meeting to pass a special resolution to add some planter boxes to the common property.
108 Changes to common property
(1) Procedure for authorising changes to common property
An owners corporation or an owner of a lot in a strata scheme may add to the common property, alter the common property or erect a new structure on common property for the purpose of improving or enhancing the common property.
(2) Any such action may be taken by the owners corporation or owner only if a special resolution has first been passed by the owners corporation that specifically authorises the taking of the particular action proposed.
