CHAPTER IV 

 GREENHOUSE ARCHITECTURE 



Architecturally, the different forms of 

 greenhouses are named and recognized main- 

 ly by the style of roof. 



Lean-to or Shed-roof Houses. These are 

 the simplest forms of greenhouses; likewise 

 the least expensive and least satisfactory. 

 There is little excuse for building separate 

 houses of this type, but they may be made to 

 serve a useful purpose when erected against 

 the side of a building or against a steep side 

 hill. They usually extend east and west, 

 with the high wall to the north and the roof 

 sloping toward the south. For commercial 

 purposes they are of little value, as they ad- 

 mit light from only one side, and but little 

 direct sunlight, except for a few hours in the 

 middle of the day. They may be utilized for 

 growing ferns and other plants requiring 

 little direct sunlight, also for starting early 

 plants, or as grape or peach houses, the vines 

 or trees being trained against the north wall.
