He said it took him years to get approved to purchase the lot across the street from the coffee shop, where he intends to build single-family homes.
Feibush said if the city allowed it, he would purchase the adjacent lot "at fair market value tomorrow."
He estimates that it is worth around $70,000 to $80,000, based on his purchase across the street.
He plans to continue to "maintain the garden and pick up trash and so it looks the way a lot should look in the city of Philadelphia and not a piece of squalor."
After the city "ignored" this lot for decades, Feibush said he is surprised it has taken such an interest, even visiting the site hourly when his work crew cleaned up the property to tell them to stop.
"What I'm hoping the next step of the city is to take other lots and try to clean them up instead of focusing on this one lot," he said.
