Most of our customers choose to build wooden platforms – they can be elevated off the ground, erected on uneven or sloped terrain, are low-impact on the environment and ultimately removable. For year round use, we recommend insulating the platform.
We provide engineered platform plans for our common dome sizes with detailed cuts, measurements, and angles that you can use to build it yourself or give to a local contractor.
Other options for flooring are poured concrete slabs (potentially insulated with radiant heat), or earthen/ cob floors. For a temporary setup, we can provide heavy duty waterproof ground tarps that can be spread directly on the ground.
We have also built a sprung dancefloor in a dome with a plywood floor over recycled tires!
Please note that we recommend building the platform to our plans to fit the dome exactly – that way it is easy to seal the cover skirt around the edges with some trim to keep weather and critters out. An outside deck can be built off the side of it. If you want to put your dome on a larger, rectangular deck, you need to account for a drainage gap around the dome perimeter to ensure rainwater cannot run under the edge of the dome. Usually in this case, you will want to build up an insulated floor on the inside.
