Garden house on the slope - Aluminum panels as a "wall substitute"

Hi,
our old garden shed is very old and we would like a new one. We also want to change the location on the property because the previous spot is supposed to become a carport.

Now our new desired spot is on a slight slope, where the front side of the garden shed would be at the level of our garden and the back part about 1 m lower. The first idea was to compensate this with concrete pillars (stacking planting rings and pouring them with concrete and iron rods) and then build the garden shed on top.

The father-in-law now says that a lot of weeds will grow underneath and also the floor wood of the garden shed will deteriorate faster because moisture comes from below.

His suggestion was to completely backfill the garden shed with soil. To avoid having to pour a whole wall all around laboriously, his suggestion was to place corrugated aluminum sheets behind the concrete pillars and then fill everything with soil.

One could take a slab of 3x1 m and then set a concrete pillar every meter or so. Then the slab would be supported at three points.

Certainly somewhat unconventional, but is the idea totally far-fetched?

Ciao
Martin

Hello Martin, you have been building the garden house for half an eternity now. Just make a proper strip foundation and gravel in between as a capillary breaking layer. You can form the foundation yourself and at the nearest concrete plant there is ready-mixed concrete that you mix yourself. The sheet metal will corrode and it is questionable how stable the pillar construction is against earth pressure...
