The Department of Buildings has released more about what caused a facade of a West Village building to become unstable Wednesday night.
The Department of Buildings' preliminary investigation found that the supports between the roof level and sixth floor failed, causing the wall of the building to buckle outward.
The agency says that caused the exterior of the building to crack.
The DOB says the Christopher Street building was constructed in 1900.
They say the property owner has hired an engineer, who will add support to the building and make the site safer.
The Red Cross helped four displaced families find temporary shelter.
