Chaltiel said it cost about $2,300 to hire a drone service, which requires two pilots.
The frame cost about $230 to build, Chaltiel said, adding that the London project cost roughly $3,475 in total.
Chaltiel's team is currently designing a house for a cliff in a remote part of Vietnam.
Unlike the dome built in London — which aimed to show the technology's potential for emergency shelters — the Vietnam home is meant to showcase a larger, luxurious house made of natural materials, Chaltiel said. She predicts it will cost just over $17,300.
