Does it include a floor?

No. It is a panel and frame shed, so you supply a level slab, deck or gravel base. A flat, solid base is what keeps the doors aligned and the panels square.

Do I need a permit for a 10x12 ft shed?

Often yes. Many areas cap shed size or require a permit and setback distances, and HOAs may have rules. Check with your local building department before ordering.

How hard is it to assemble?

Plan on two people and most of a day. The panels are large and light enough to lift, but the frame must be squared and anchored before the roof goes on.

Galvanized steel resists rust, but cut edges and scratched spots can corrode over time. Touch up scratches and keep soil and mulch from piling against the base.

Can I put shelves or hang tools inside?

Yes. The steel frame takes shelving and hooks, and the 10x12 ft floor area leaves room for a mower plus a work aisle. Anchor heavy shelves to the frame, not the panels.

How does it compare with a resin or wood shed?

Steel is tougher against weather and pests than resin and needs less upkeep than wood. Wood looks nicer and is easier to modify, but it rots and needs sealing.
