About Lloyd Kahn

Lloyd Kahn started building his own home in the early '60s and went on to publish books showing homeowners how they could build their own homes with their own hands. He got his start in publishing by working as the shelter editor of the Whole Earth Catalog with Stewart Brand in the late '60s. He has since authored six highly-graphic books on homemade building, all of which are interrelated. The books, "The Shelter Library Of Building Books," include Shelter, Shelter II (1978), Home Work (2004), Builders of the Pacific Coast (2008), Tiny Homes (2012), and Tiny Homes on the Move (2014). Lloyd operates from Northern California studio built of recycled lumber, set in the midst of a vegetable garden, and hooked into the world via five Mac computers.

  1. I dabble with polyhedral design, and build all kinds of buildings, models, and unusual structures.
    Symmetry and the use of repetitive angle cuts is handy, and the structure appears to have been assembled quickly and easiloy, after the preparation.
    It's a thing of geometric beauty.
    But I think it would be too fancy, and too expensive for my taste.

  2. This structure is a tetrahedron on top of an octahedron, forming 3 flat rhombic faces for the roof, continuing down to the 3 corners of the floor. There are a total of 9 big triangles. (6 below, and 3 at the top)
    It appears that each edge is 12 feet, so there is a 12'-on-the-side triangular floor, giving the building a floor area of only 63.35 sq ft.
    For comparison, an icosa cabin, in which the same nifty triangular frames could be used, would have a pentagonal floor with 247.75 sq ft.
    There are a total of 15 of the big triangles, so the icosa is admittedly bigger over-all, having 66% more surface area.
    But, the floor area is almost 4 times as much! (3.97, to be exact)
    And the space would be much more usable, with less wall leaning or inside tiny corners.

  4. Try misting the area of the wing skin that is out of shape and then place the entire wing back in the cores with weights on a flat surface until that area has fully dried. This is a surprisingly easy way to fix some wavy trailing edges on a foam core wing sheeted in balsa or obeechi.
