The "Spherical Tree House" concept borrows heavily from sailboat
construction and rigging practice. It's a
marriage of tree house and sailboat
technology. Wooden spheres are built much
like a cedar strip canoe or kayak.
Suspension points are similar to the chain
plate attachments on a sailboat. Stairways
hang from a tree much like a sailboat shroud
hangs from the mast.
Spherical architecture has many unconventional features. Conventional
buildings separate walls, ceiling and floor
with hard lines. In a sphere the walls and
ceiling merge into one. The function changes
but the form remains the same. It is a
unified structure with one continuous wall.
I call this uniwall construction. There are
only 2 sides to a sphere, inside and
outside.
Both wooden and fiberglass spheres are insulated. Vinyl upholstery
fabric is stapled to the frames (lines of longitude). Each fabric
joint is then covered with a decorative wood strip. The wood strips
come together at the top and give a nice cathedral ceiling effect.
The joinery is yacht style with much brass trim, varnished wood and
cane doors. They have closets on either side
of the door. These function as partial
bulkheads to reinforce the door opening as
well as adding cupboard space.
