expert carpenter needed for advice

im planning to build a 5x5x6 in ft LXWXH (respectively) detachable grow room. which im actually placing outdoor, im going to spend money on these since these will be a final grow room. so i will be needing an expert advice. these will be place on the roof deck which is on the 5th floor, thats why i plan these to be detachable with wheels. so i will be needing lightweight materials on these grow room. i already have an idea how these will be built but i need a complete advice from the experts since i have no experience in carpentry. please dont bash me on these post, thank you in advance for the help.

you need more details befor you can really get answers.

does it need to be light proof? is this going to be lighted or green house

is this an apartment? does it have to be stealth?

any other info you wish to give would help

You might want to do a little google research on "foam panel construction". I personaly have never worked with it but have witnessed a lot of it in my 20 yrs. exp. It may be your answer to light weight. You will still need a conventional floor system(2x4 or 6) with plywood/osb flooring. I would go with a gable or shed style roof.

Good luck

I'm not an expert, but i've taken two years worth of trade school and graduated for carpentry.

no it would be placed on top of our roof for space issue so it doesn't need to be stealth, i will be placing doors though so no curious cat can fuck up my plants and yes i would be placing lights inside. im planning to build more like of a indoor at night and can be converted outdoor in the morning, thats why i figured i should go lightweight and can easily be detached when planning in moving. im not even sure if by doing these i will be stressing the plants.
