Shed & garden pads

50 concrete shed and garden pad ideas for a dry, level, lasting base

A small building deserves a foundation that keeps it dry and square for decades. See how a well-placed concrete pad gives a shed, greenhouse, or garden studio a clean floor, a dry step in, and an easy route to the rest of the yard — the quiet groundwork that makes a backyard project actually work.

Start from the ground, not the building

The most common regret with a shed or studio is not the building — it is a pad that sits too low, drains the wrong way, or stops right at the wall with no dry place to step. A good pad is set on a compacted, well-drained base, kept slightly above the surrounding soil, and sized a little past the walls so you get a threshold, door clearance, and room to move equipment in and out. Pick the setup you like here, then get the base and drainage right.

A practical pad

Design details worth deciding before the pour

1. Get the base and drainage right

Set the pad on a compacted, well-drained base and keep it slightly proud of the surrounding soil so water runs off, not under, the building. Ground that stays wet under a shed causes far more trouble than any finish choice.

2. Size the pad past the walls

Make the pad a little larger than the building for a dry step at the door, clearance for the door swing, and room to roll a mower or cart in and out. A pad that stops exactly at the walls quickly feels cramped.

3. Match the section to the building

A small tool shed is a modest slab; a studio, a greenhouse, or a building that stores equipment often needs a thicker slab or a thickened edge where walls bear. Confirm the detail against the building specs, not a guess.

4. Give wet work a slope and a drain

A greenhouse, potting court, or wash station benefits from a gentle slope to a drain and an easy-clean surface. Keep soil, mulch, and irrigation from constantly wetting the slab edge or the wall above it.

Planning references

A small pour still rewards a little homework

Use these references for slab, edge, and permitting context, then confirm the local rules that apply to your project.

Local code

The ICC model code portal gives context; check whether an accessory building or its slab needs a permit or setback where you live.

Next step

Use the visual direction to start an estimate

Measure the pad a little larger than the building, and add any potting court, greenhouse apron, wash zone, or connecting path separately. The calculator helps with the concrete field and base; it does not confirm the building specs or permits.
