A small dome (15 feet) install like this one will take half a day to put up and another half day to install all of the window hardware & hang the door.  We can do some of this work or all of it for you.  I can install domes up to this size by myself without a helper, which will save on labor costs for you.  A 15′ dome can seat 6-8 people comfortably in a circle.  A 15′ diameter dome is 176 square feet.  We can also make you a dome kit if you’d like to put it together yourself.
