Material Required for a 20 x 10 Lean-to House 



Let us figure out just what is needed for a lean-to house, 

 twenty feet long and approximately ten wide. Suppose 

 we can get 7 feet of headroom on the wall against which 

 we wish to build. Then we can figure on a height of four 

 feet for the front wall, which will require 6-foot posts, as 

 they should be set at least two feet into the soil. For the 

 front wall then we will require five 6-foot posts; double 

 boarding enough to go from a foot below the surface to 2j^ 

 feet up the posts (twice 3^ feet x 20 feet), or 140 feet; 



Ground plan of 10 x 20 lean-to house. 



20 feet each of 2 x 4" eave-plate and 2 x 6" sill; and ten lights 

 of 1 6 x 24" double- thick glass. For the ends there will be 

 required 4 g-foot posts; approximately the same amount 

 of boarding as for the front wall; 20 feet of 2 x 4" sill; 50 

 feet of " side bars" (to hold the glass) ; and 60 square feet of 

 glass. It is usually possible to pick up a secondhand door 

 of some local contractor, at a very low price; or one may 

 readily be constructed of boards and roofing paper or shin- 

 gles. 



For the roof there will be required 20 feet of ridge, 13 

 lo-foot sash bars, 2 lo-foot end bars; and 3 ventilating 

 sash. A little may be saved on the ridge by having it sawed 

 in two vertically, as it will support the sash bars just as well 

 and fit more snugly against the side of the house. Get 

 the style of sash bars known as "drip" bars which means 

 that they do not drip! If you get the ventilating sash made 

 the right size you can easily put the glass in yourself.
