Here we have a set of plans and instructions to build a 19' 6" diameter geodesic dome, measurements are in feet and inches for US customers who don't want to convert from millimeters.
They are based on our popular GD27 Geo-Dome kit
19 foot 6 inches diameter.
290 square feet floor area.
3 frequency exact half dome.
All timber construction.
All the plans on the site use a hub-less system so you don't have to make any hubs. All you need are some basic woodworking machines like a table saw, jig saw, electric drill/driver and a few hand tools. The picture on the left shows a completed dome covered in 5 season horticultural polythene, instructions are included for covering in polythene but you can cover with other materials like polycarbonate, aluminium etc. E-mail support is available if you have any questions or get stuck at any point.
