Roads — Extended houses on Roads

Good Evening Sir,
Parking is already a problem in many parts of delhi but what concerns me further is the extended houses( in form of stairs, slope, or parking) in delhi.
These extended housed not only lowers the width of the road but also create problems for pedestrians, children and old aged in particular. I have attached photos of gali no 9 ( next to rajmandir hypermarket), Mahavir Enclave in the email but the problem is huge prevailing in other parts also and needs to be addressed.

I request you to please take necessary action through the concerned authority.

Thank You.
