Site Preparation Guidelines for Storage Sheds / Gazebos / Kennels



We recommend that your storage shed or prefab kennel foundation be a level pad of ¾” crushed stone, 3″ – 4” deep, 1′ larger than the size of the shed (for example, a 10’ x 14’ building would require a pad at least 11’ x 15’). This will allow for better drainage around the perimeter of the shed for rain/snow melt dripping off the eaves – especially, if you are not planning on installing rain gutters on the shed or dog kennel. Water splashing directly onto the ground will, eventually, create a muddy area and splash up onto the shed or kennel walls. The gravel shed foundation prevents this to extend the life of the building.


  • To prepare a storage shed or pre-built dog kennel base, remove the sod from an area slightly larger than the pad, level the site by removing dirt where necessary, and spread the gravel to a depth of about three or four inches. Tamp the shed or kennel base gravel down with a piece of 4-by-4 or metal tamper until it is evenly distributed and the site is flat and level.
  • A “frame” of pressure-treated 4×4’s or cement block will help keep the stone in place and create a neater appearance; however, it is not required.

Cement pillars, with or without tie-downs, are required by some municipalities. Check local regulations for quantity and recommended placement.

NOT RECOMMENDED: Cinder blocks. Inevitably, there will be some settling after your shed or dog kennel is delivered and placed on site. Placing a prebuilt structure up on cinder blocks greatly increases the risk that your the building will settle unevenly. This can create twisting and offset door and window frames. Additionally, delivery and placement of storage shed base or prebuilt dog kennels can be with more difficult with cinder blocks as a base.
