what is the best design for the base of a 6x8 greenhouse. I am having a cement perimeter to rest it on but is it better all cement or gravel or what else?

my frame is on concrete and i have pavers down the middle. the rest is soil so i can plant things in to it. i have staging down one side, that can be stowed away so i can plant things when they are ready.

we laid or base on gravel with slabs,i think the gravel is good for drainage

The greenhouse I have shown in my blogs has two thirds of the floor laid with slabs and one third is a sand plunge. The slabs provide a walkway and a firm surface for the bench to stand on whilst providing good drainage at the same time.
The sand plunge could easily be repaced with a composted bed for growing crops or more slabs.

hi i had some brick rubble left over so what i did was from the width of the door i put some scrap wood each side of the door ,the lengh of the greenhouse put some pegs in and concreted it leaveing it the thickness of a block paveing below .so when the concrete had dried i took the 2 peices of wood out (suttering) and layed my brick paveing on and put a angle of cement on the edges so they would not move .....i used what i had left over just make it safe and level so you dont trip or fall

our greenhouse is bolted down onto custom made blocks, all this was here when we moved in, i have resited it and have paving slabs down the middle and all the rest is gravel.everything we grow in the greenhouse is in large pots.then at the end of season , we empty all the pots into the compost heap, wash them with detergent,and put away in the shed..................steve

a cement base is not a good idea for these reasons,if in the future, you want a larger greenhouse or smaller one your stuck, drainage is another l reason, and a concrete base is not easy to uplift & despose of,you are cheaper & better to use non cresoted railway sleepers cut to size,
these give it extra hight, & you only need 4 coach screws to fix it on.
