Nearly all dome/dome-kit manufacturers seem to be in the U.S., unfortunately, but the web pages can be an inspiration:
Recently John Moon contacted me mentioning dome construction workshops that he and Sean Hellman are running in the UK on 16th-18th April (Osho Leela, Dorset), 11th-13th June (Buckfastleigh, Devon), 23rd-25th July (Stoodleigh, Devon). Prices range from 85 to 99 pounds, including accommodation - I've no idea if there are concessionary prices, but see the contact details below to find out more. Disclaimer - these aren't my workshops!
Here is John's description of the workshops:
"You ask about the content of the dome tent workshops, with a view to highlighting them on your pages. What we intend to do is as follows:
Hopefully 20 satisfied dome tent builders ready to grace the fields, camps and festivals of the world with multicoloured domes of every shape and size!"The contact information I have is:
