Floors

  • 2"x10"x16' (x45)
  • 4'x8'x23/32" (x32) OSB or Plywood Subfloor

floors1

floors2

3 x floor rafters

floor-rafters

This is made of 2"x10"x16' boards with 24" on center spacing. The outer boards are full length all others (including horizontal caps)
are cut with 3" off to fit on the inside.

2 are used for bottom and one for top floor.

upper floor rafters

upper-floor-rafters

This is a modified floor rafter square with space cut out for the stairs.

Lower Subfloor

lower-subfloor

16 sheets of subfloor tiled to cover 2x floor rafter squares.

Upper Subfloor

upper-subfloor

This is the same as lower, but with cutout for stairs.

Lower Walls

lower-walls

Lumber needed to build all lower walls:

  • 2"x8"x8' (x2)
  • 2"x6"x16' (x17)
  • 2"x6"x8' (x85)

Left-Back Wall

left-back-wall

This is the wall-segment left of the doors and touching the back of the building. It's a plain wall segment with
framing for an air conditioner.

Left-Front Wall

left-front-wall

The next segment (left to previous when viewed from side) touching corner with door. Has window frame.

Right-Back Wall

right-back-wall

This is the side wall touching the stairs, it also has a window opening.

Right-Front Wall

right-front-wall

I decided to go with a slab for the foundation. It only costs $500 more and saves around $800 in lumber (not to mention a lot of labor) and the end product is better.

The guys doing the slab will need to know where to put anchor bolts, this will help:

Tweaked window and door openings for new sizes and so that studs line up more often. Also removed perlins and will be putting foil lined sheathing on top instead.

Pro-tip. The foil lined sheathing really helps with cooling costs, but it destroys cell reception inside the building by making it a giant Faraday cage.

Nice! Thanks for sharing! I'm looking to build a paid of smaller sheds and am starting with design in OpenSCAD. Being new to OpenSCAD, what you've shared in this gist will be tremendously helpful. It's a great example of a way to get the design done. I'll make sure to share my design and pics too!
