Do we need authorities approval if I plan to expand a small piece of land just opposite my house for my carpark use?

If yes, who and how do I get permission?
Is there any other things I should know dealing with this?

I’m not familiar with this kind of stuff

Opposite of house, yes
Too small to be a reserve land, just a few meters area
Some of my neighbours did plantation on that

That’s bad, we don’t have spaces to park cars anymore
Neighbours doing plantations on that land tho, means I can sue them for using public land? Jk

Exactly what I’m planning to do 😅 but it’s not a pandang whatsoever, just excess piece of land left by developers because they can’t build any further

I’m not master race btw
Felt illegal tho doing this, I don’t want to waste my money on doing it and destroy in future.

Nope, this structure definitely won’t disturb anyone around me.
Only fear of jealous neighbours, reporting me to authorities because I’m taking advantage of that land.

Plan to do this so that our neighbours won’t argue because of parking spaces.

Typical case we see, argue because of parking...but if they complain I can’t do anything also

That’s the reason of this thread
Asking permission from authorities, before I build structure on that
