The end result of digging.
The pipes are in...
...and the trenches closed..
Now inside, the big dome upstairs...
...downstairs...
...and the vestibule.
This is in the small dome.
That is where all the ducts come together, soon.We have visitors...
Loes, doing taping.
Good team work. Noud & Pieter (re)hanging the garage door (low head room rails).
We started the sheetrock in the big dome.
...
Well, hello there.
Sliding door in the kitchen
Pieter making connections in the radiant heat tubes
"Vakmanschap is meesterschap" 
70 PSI and holding
Trenches for the geothermal heat exchange
Pieter supervising ;))
This beauty is a Cardinal chick
We finished the siding for the small dome. It almost looks like a barn!
Inside, the last sheetrock upstairs,
...
Bathroom with light tunnel and...
The toilet that is almost without all that funny stuff in the back! Trivial, only until you have to clean it.
The workshop area is progressing slowly,
First "corner" is done.
Window in the bedroom
With a little help from the truck
Now the front door
Done!
And together.
Absolutely worn out.....
Pieter's workshop is almost ready
...
Jolanta is busy experimenting with tapes and compounds
The supposedly best, Straitflex, is a pain to apply, stiff and does not want to stick to the "buttered" surface. I had to use spray to glue it.
More difficult connection
I use this tool to make nice corners and it works well on the multiple angles in one location.
The outside of the domes is backfilled.
The road is wider; too many trucks got stuck in the curve.
Now some gravel...
...person gets tired from all that work.
Here still lots of excavating to be done later.
Finally the siding!
The wood under the house-wrap was well protected over the winter.
Nice fella, not poisonous, eats mice and birds.
Pieter is continuing with the framing in the Big Dome
Second floor: ceiling and floor, just in case we want to make more rooms. 
Framing finished! 
Radiant heating pipes in the Small Dome 
Aluminum plates to reflect the heat/cold 
Installing the first sheetrock in the workshop
Nice trench for the water and electric 
...from the well 
and the transformer to the house 
Unexpected visitor
