I’m going to put forward an alternative to JT.
All owners bought into the strata knowing that the foyer faced west. The situation always existed.
Therefore any remedy is not a maintenance or a nuisance issue, as the situation existed from the beginning.
In order to have something done, you can get 25% of owners to put a motion for a general meeting to get something done ( you specify what you want done).
Alternatively put the same motion on the AGM, where it requires only your request.
The motion requires passing at a general meeting as it’s a change to the common property, which can’t be passed by the committee.
At the general meeting, it will still require a majority of those voting in order to pass.
Start lobbying your neighbours now.
