I built a green house out of the hoops from
an old trampolene. I want to know what I have to do, or even if it is possible to
cover the greenhouse with concrete to turn it
into a studio. I have never worked with this
form of building and am not sure what to do.
Do I need to reinforce the frame, do I need
to take the plastic covering off, or just
cover it with rebar and cement?

Concrete is very heavy. Apprx. 4000 pounds per cubic yard. I doubt your greenhouse can support that type of load without extensive bracing.

There is a fairly new type of lightweight concrete that contains some styrofoam beads to make it lighter and can be sprayed on over the rebars to the required thickness that may be better suited to what you are doing. This would reduce the amount of bracing required.

There are also other materials that can by sprayed on to create a room that do not contain concrete but are instead made of an expanding foam. The foam can have a hard shell sprayed over it after it is cured.

Thanks for the info. I did not realize that
concrete carried that much weight. What do
you think of using hypertofu in place of
regular concrete. I've started making stepping stones from it and it seems pretty
