No excavation
No post holes, no concrete trucks, no waiting for footings to cure. The ground you have is the foundation you need.
3D model + framing & decking plans
DeckJack is an adjustable leg system you pair with our complete plan set to build square deck modules that bear directly on the ground — and level themselves to it. Build one this weekend. Add another next month.
A traditional deck means permits, post holes, concrete, and a framing plan you hope you got right. A DeckJack module is a self-contained platform on four adjustable legs. It sits on the ground, levels in minutes, and joins with its neighbors to become any deck you can imagine.
How it works
Download the DeckJack 3D model with your plan set. Make it yourself or have it produced locally — four jacks per module.
Follow the included framing and decking plan: a simple, repeatable frame from standard dimensional lumber, decked with the boards you like.
Place the module where you want it, then dial each DeckJack leg until the bubble sits center. Ground slopes? Doesn’t matter. Done.
Ground-bearing by design
Each module stands on four DeckJack legs with wide feet that bear directly on the ground — no post holes, no poured piers. Independent screw adjustment at every corner means you can true up a module in minutes, and re-true it seasons later if the ground moves.
Modular & expandable
Every module is the same repeatable build, so your second one goes faster than your first. Butt them together for a wide platform, stagger them for an L, or run them along a fence line. Your deck grows with your budget and your weekends.
Why DeckJack
No post holes, no concrete trucks, no waiting for footings to cure. The ground you have is the foundation you need.
If you can cut a board and drive a screw, you can build a module. The plans assume a circular saw, a drill, and a free weekend.
Cut lists, framing diagrams, decking layout, and step-by-step assembly — dimensioned for standard lumber off the rack.
Seasons change and ground moves. A quarter-turn at a corner brings everything back to dead level.
Freestanding and low to the ground. When you move a module, the yard underneath recovers — no scars, no stumps of concrete.
Buy lumber one module at a time instead of financing the whole deck at once. Each module is a small, finishable project.

The details
* Freestanding, low-profile structures are exempt from permits in many jurisdictions — always confirm with your local building department before you build.
Questions
A digital plan set: the DeckJack 3D model plus complete framing and decking plans for building deck modules. You supply the lumber, fasteners, and elbow grease.
Many jurisdictions exempt freestanding, low-height structures from permitting — but rules vary widely. Check with your local building department before you build.
It doesn’t. Each leg adjusts independently, so modules sit dead-level on sloped or uneven ground within the legs’ adjustment range.
Yes. Nothing is anchored or buried. A module is a self-contained platform — lift it, relocate it, re-level it.
Most builders can frame, deck, and level their first module in a weekend with basic tools. The second one goes faster.
A circular saw (or miter saw), a drill/driver, a level, a tape measure, and a square. That’s the whole list.
