This building is considered by the City as a remodel project. Two walls of the old Rosebud Cafe (south and east) were retained and the rest built off of that. I checked the building permits with the City of Fort Worth and no new construction permits were issued for this site. It has been a while since I have done a project in Fort Worth South, but I do remember that the remodeling a building had fewer requirements than "New Construction".
As for the Cook Children's project across the street, I believe they asked all of their properties to be removed from the Form Based Codes Zoning. I checked the zoning on their property and the new Chipotle. The new Cook Children's building is zoned "G" Commercial, and the Chipotle is zoned for the Form Based Codes.
