Yes... the concrete houses.. they are made kind of like the way they would make the concrete boats.. basicly a wire housse that has it's holes filled in with concrete...
funny story.. unless it was yours... back in the early concrete boat days.. this guy spent months making the wire framework.. out back.. next to his house.. then on concreteing day.. he was there but going to try the gunnite spraying to apply the concrete.... before troweling it smooth and fair along the hull... now... all the boat has to be cast the same day.. to make a seamless one piece boat... as expanson and torque will alwaays find the jont and cause a crack.. so he's there startng to spray the concrete... and it flys up.. goes through the wire into the boat.. through the wire on the other side.. and out splatting aganst his house... so this wire framework he's got 10's of thousands of dollars and man hours into.. isn't working right and it all has to be done today so it can set up and cure as one piece.. so he had to shift to pushing the concrete by hand into the wire.. then finishing it.. wth a shorter crew than normal.. because he was gong to have the spray do most of the work.. he.. his wife and children.. and the small crew beat them selves well through the night.. to save the started concreted form... later gunnite sprayed boats had a wooden inner form to hold the concrete... but not seeing the inside... you'd not know you had fulll penetration aganst the wood.. leavng possbile voids.. all this is oK in a house.. as you can concrete and stop and not worry about cracking.. the life pod house was done in stages... it had it's doorways concreted first for rigidity..as shown in the application photos.. always have a full bacing if you're going to be spraying onto your form.. that concrete house was a full wire/rebar house... before they put the concrete on...
and the concrete house.. with no sprayed foam... would be like a dutch oven in the sun....
the new concrete/foam houses use a foam block.. like a concrete block.. you stack them like concrete blocks real light and easy... lay rod down through the blocks.. and tiie to rod land horizontally along the courses and then pour concrrete down to fill up the foam blocks... so you are stuck with straight walls.. but they are solid concrete /rod ... without the need for forms... as the forms are left in place as inside and outside foam insulation... [ stucco the outside.. and nsde either stucco or sheetrock applied to the foam ...and finishsed in the regular manner for it..] it's dead quiet in the inside.. and able to be heated with a light bulb ..well almost...

this is one of many foam block systems available.. I went to a day long instructonal on it's use and methods by another company than what the link is to.. and you can stack them and pour them with only a little help... and they have a flat roof system fot it also... making a great roof garden/water catchment space on top... all done in foam .. with the rods and concrete inside... very tornado/hurricane resistant .. but not as wind sleak as the rounded bubble houses..
sorry to run on so...
