Can be adapted for Efficient and Economical Independent Student or Senior Housing
(see floorplans below)
The precision-cut 2x4 geodesic frame kit is exposed to the interior.
The exposed frame and triangle panels on the dome ceiling create
an awesome three dimensional pattern and a very strong building.
Our Backyard Dome kit is modified on the lower perimeter
to include vertical wall framing for conventional doors and windows.
A braced four feet high, ten-sided, perimeter riser wall is constructed
under the modified hemisphere to lift the dome just enough
to accomodate the height of a standard pre-hung exterior door.
The total height of the dome at the center is 16 feet.
Our 'backyard dome kit' is designed to be assembled by people
who have limited prior construction experience.
All the components are small enough to be easily handled by one person.
All EconOdome frame kits are assembled with screws and a rechargeable drill.
The floor may radiantly heated, if, you are building where it gets cold in the winter.
Below is one possible single story floorplan.
An important part of building a small and economical ten sided dome is the floor.
The 'MesaBase' foundation and floor minimizes the need for excavation and allows for building on sloped ground.
The sloped ground is leveled
(after installing drain, water, gas, and electric lines)
by creating a mesa
that retains the gravel with concrete blocks, rock filled tires, or gabions.
The 'mesa base' inhibits erosion and
provides a level area free of vegetation and mud adjacent the dome.
The mesa base also insulates the ground adjacent the building
because of air spaces between the rocks.
Railroad tracks and locomotives are supported by rocks,
so why not domes and porches.
The concrete floor (reinforced with rebar)
anchors the dome as lag bolts inserted into
the inside perimeter of the permanent pre-cut treated 2x8 lumber base.
The base boards lap at the corners,
thus creating a strong interconnected base/foundation.
Set concrete blocks in a circle that is a few feet bigger that the dome you want to build.
Level the blocks by digging out some dirt where the blocks are too high.
Add extra blocks if necessary to accomodate the slope or to accomodate an abundance of rubble.
Space the blocks about an inch apart.
Cut notches in the top of the blocks and lay-in a ring of epoxy coated rebar.
Fill the blocks with concrete to secure the rebar and blocks permanently in-place.
Put some plastic mortor mesh against the inside surface of the blocks
to keep the gravel from escaping thru the spaces between the blocks.
Then fill the cylinder with river rock or concrete rubble.
You have just created a level and raised mesa that will keep your concrete floor high and dry.
Now you can frame your ten-sided dome home using a precision-cut EconOdome 2x4 Frame Kit

elevated above a 4' high perimeter riser wall frame kit.You can build with either a 'Basic' or a 'T-Beam' EconOdome frame kit.
The EconOdome kits will cost more with a T-Beam frame kit.
However, you will eliminate the need for installing and finishing sheetrock
on the dome ceiling. You will notice below that with the T-Beam frame kit,
