In 1998 the Keystone renovation was complete and the building was renamed to "Keystone Lofts". With only 34 units Keystone Lofts is one of the smaller buildings in Houston's downtown. The Keystone Lofts units range between 1,350 and 4,400 square feet, with amenities such as hardwood floors, 10-foot ceilings, tiled jacuzzi tubs and granite countertops.
The Keystone building was originally designed by architect Joseph Finger and built in the early 1920's
