280 COMMISSION ON BUILDING DISTRICTS 



Sec. 18, Par. (e). Where additions are made to an existing plan, even 

 though they may be on separate lots adjacent on either side or to the rear, 

 it is highly desirable that the whole plot should be considered as a unit in 

 reckoning the distribution and sizes of yard and court spaces. 



Sec. 18, Par. (f). If in a B district an existing building 150 feet high 

 had a rear yard only 15 feet wide instead of 25 feet as herein required, the 

 first additional 12-foot story would not have to set back 27 feet from the 

 rear line, but only 17 feet and in the case of a stair or elevator, the rear 

 wall could go up straight on the existing rear wall.
