Spot footings..no sill beam???

[Mad-Dax]

I want to build a quick down and dirty shed...sorta like a permanent tent or similar to what Lowes and Home D. sells I see on the parking lots all on display.  Would it be catastrophic to just use the 8x8x16 blocks on the ground matrixed every 6 ft. under the 2x6 joists 16" OC?  Building about 16'x30'...  Do I have really have to use/make sill beams underneath like 4x4's in 3 to 4 rows spanning the 30' under the joists on top of the blocks first?  This is Dallas, TX area...I am not insulating or anything like that.  I thought this might be a better route than renting a few storage units for tools, wood, appliances, etc while the real house is built.

Thanks

I've got a skid foundation in the Enchilada plans kit, but, in general, you do need to support every joist on something structural to span your blocks or whatever is your foundation.

In the skid foundation mentioned above the the beam is a double PT 2x that is at least 2" deeper than the joists. This beam rests on a gravel trench footing and then the floor joists are hung inside these beams. There are details in the kit about ventilation and moisture barrier that also need to be done right to make this simple foundation last.

Thank you for the info..my wife and I have not decided on which plans to get yet..we like the Big Ench, but want to make a two story even possibly a 3rd story for a room observatory/ nature watchtower.  So we may need the 2 story kit.  Maybe we can just modify the Big E.  We want a modern look with a slight flat roof.  I think we can get one of your plans and then modify it into a look like this in a way  (these are prefab)

That will be later down the road...months from now though.  We are going out tommorrow to try and put up this 16x30 shed....start on it anyways.

The Enchilada plans would not be good for a tall building. It is limited to 14' wide and a one story with loft.

A better choice for what it sounds like you want would be the 20' wide Universal. It has a full sized stair that can be extended up and down, 2x6 framing, and a foundation that could have a third level on top.
