When you need to coat the dome depends on your climate, the type of material used in the Airform, and the desired aesthetics for the dome. A variety of coatings are available ranging from elastomeric coatings, stucco, shotcrete, and metal cladding. Monolithic Domes can be built quite quickly. In general it takes about six to eight weeks to get the Airform ready. Then about two to four weeks to build a house sized dome shell.
Large buildings require about six to ten weeks.
As with any building project, the finish work requires a great deal of time, usually three to six months for the interior of a home. Affordable feasibility study David South, President of Monolithic Dome Institute, Inc., says, reople who are just thinking about building a Monolithic Dome home, but don't know if they can afford to, need some convenient stopping points. So, MDI has initiated two different programs to do just that. The first of these is a Free Evaluation . MDI's professionals will then evaluate this information and give the prospective dome builder a cost approximation.
