Airform Inflation and Insulation



We FINALLY rise out of the dirt! 
Everything is happening so fast! It is both exciting and daunting because this means we have a ton of work to do to be able to get it closed up for the winter. This is awesome progress and we are totally wowed by the space that is created! It is much bigger than we imagined. The square footage is a little over 2700 sq feet (certainly not a huge house) but having it on all one level with high ceilings makes it feel HUGE!

The builders attached the airform to the ring beam with all the needed equipment under it.
It is attached by metal bands with concrete screws directly into the ring beam.
 
Next they built all the wood bucks that go up against the openings. The bucks are large flat wood exterior support walls that push back against the balloon like airform. This gives a nice flat edge to work against. This helps get sharp edges for all the openings on the otherwise soft airform.

After the fans are turned on the house inflates in just 5 minutes.

The interior of the inflated airform is translucent and an orangeish red. Walking in through the airlock was amazing! It was our first look at the physical space we are creating. 

Things continue to progress quickly and this view of the airform was only visible for 2 days before they began spraying the insulation. The entire inside of the dome is sprayed with urethane insulation at about 4 inches of thickness. It is done it two layers of 2 inches. In the first layer the buiders insert rebar hangers.
These hangers are then secured under the next layer of insulation and the rebar installation begins.
They also began installation of the spray block for our large opening. The cement will only be sprayed up to the inside edge of all the wood. We chose a design element that we saw on another completed dome because we thought it was a simple and interesting way to add a little something extra to our feature wall. In the end the small arc on top will look like a little bite out of the top of the arch. 
It is really exciting to see this all coming together in 3D after looking at it so long on paper. Stay tuned as I try to keep up with the rapid pace!

Radiant Heat and Drywall DONE!

  We are DONE with dry wall and everything is painted!!! It looks almost like a real house inside. I can top that news by saying WE HAVE HEAT!!! Lets take a moment to celebrate having a functioning heating system in a cold climate in the middle of winter! The marathon of drywall is done for now. We still have the master wing of the house to do after we move in but we would like to just pretend we are done for awhile. It was a long slow dusty process but it looks amazing. The flat walls are a cool white and the dome surface is a warm cream. All our color will come from materials not paint colors. We have plans for wood, metal and stone throughout the house. We are finally getting to install more lighting fixtures and finalize all the outlets and switches. To watch a five minute video walk through CLICK HERE . Greatroom floor outlet in the center of the room. We decided that since the room is 32' across it needed an outlet in the center where furniture would be. Kids bathroom sconces

Construction Video and Geodesic vs. Monolithic Domes

While we wait as patiently as possible for spring to dig holes for our new perc tests my posts will be directed towards general dome related things. Most people I talk to know what a dome home is but are clueless about the different types of domes. This post is to help show the differences between geodesic and monolithic domes with a few pictures of each. The saying "a picture is worth a thousand words" is true and a video must be worth 100000 words. (Watch a video of a monolithic dome being constructed at the end of this post to really wrap your mind around the process.) Many people have asked me how a monolithic dome is different than a geodesic dome. The answer can be quite simple. A monolithic dome structure is all one piece and geodesic domes are made up of many pieces (triangles) connected together. Monolithic domes are sprayed concrete like some inground pools. Here are some photos of interior and exterior monolithic domes. Compare the above Mon

Spider Tie System Stem Wall Forms Complete

We finished building the stem wall forms last weekend! Personally I think they look super cool and I will be a bit sad to deconstruct them after we pour them. So much work to build them only to take them apart again and then just bury the whole thing underground. The original plan was to pour the stem wall on Friday October 11th but our weather was once again not cooperating. We are got yet another rain storm fueled by a storm/hurricane that thankfully mostly missed us. Because of this storm we are now scheduled to pour it on Monday October 14th. This was quite the ambitious DIY project for us. I can understand why we couldn't even get a company to put in a bid. Part of me is amazed that we pulled it off...so far. The truth will be in how it holds up to the concrete. It took almost 3000 screws to put the plywood skin on the Spider Tie towers and we cut 120 sheets of plywood! We joked that we were the Dometastic saw mill. Watch some videos of the process. It is
