This 38.5' dome home was built for Donn Piatt in Alabama during the summer of 2011.
Donn built with an EconOdome T-Beam frame kit and hired local by-the-hour help.
Donn also purchased a riser wall frame kit and pre-cut triangle panel kits.
This is the construction process.
Photo taken as concrete footing was being poured & leveled.
The space in the concrete block stemwall is for a foundation vent.
The floor is framed with 2x6's over the perimeter stemwall and some beams.
Tongue and grooved 3/4 inch thick subflooring is glued and screwed over the floor framing.
The pre-assembled and internally braced perimeter riser walls are assembled flush with the outside of the floor.
Next the pre-assembled trapezoids are assembled above the perimeter riser walls. All conventional door and window framing is already within the factory built riser walls and trapezoids.
The upper part of the dome is framed by connecting the struts one at a time per the assembly diagram. It is easiest to use a rechargeable drill with a tip/bit that fits the stainless steel screws. Screws and bits are supplied with all EconOdome frame kits.
Next, the triangle panels are installed and sealed one level at a time. Doing this makes the work easier and also completes the interior on the second floor as well as the exterior. The triangle panels include insulation plus interior and exterior finishing materials.
Now the lower part of the building can be covered and sealed.
The lower part of the dome can be sealed in the same manner as the upper part of the dome.
Now the interior wall framing can begin.
Walls, beams, and a perimeter ledger are put in place to support the second level 2x8 floor framing.
You can see the inside perimeter 2x8 ledger in the back of this photo.
The floor joists for the second level floor frame are put in place per plans.
