Hi, i''m very new to domes in general and after doing some research on the inter-web have become hooked on all things "dome" So much so that I''ve now decided to build my wife a dome greenhouse for the garden, my question is "is it possible to build a dome shaped structure (I understand it wouldn''t actually be a dome)with 2 vertical sides so that it would fit in to the corner?"I guess it would be like the lean to designs that can be found but I wonder if a second vertical wall would weaken the structure beyond practicality? I hope I''m not being too stupid thinking of this but it would very useful to find some plans if they exist. Thanks for your time
