Neighbors Building New House, Adding A Staircase/porch On Their Property Line But It Is Impacting The Use Of My Driveway?

I live in Brooklyn, NYC and my neighbors have decided that they would totally rebuild their home. This process has been a nightmare with problems including: damaging the concrete in my driveway, coating my dad’s car with brick and saw dust and generally using our space without our permission. Recently, we’ve come to find out that they are adding a staircase up to their side door which is located in our driveway (my whole neighborhood has driveways opposite their side doors). This would have been fine however they have built up a concrete structure around 5 feet high and on the property line that goes around 1/3 of the way through the back of our driveway. This will limit our families use of our driveway because there will not be any room between this structure and our property line and we will be unable to open our car doors as a result. Is there anything that we can do to get them to take this down or are we stuck with limited use of our driveway and ultimately the loss of value of our property?
