Before you start
  • Unverified concept materials. Not construction-ready. Obtain independent qualified design and review before building.
  • Use the loft for light storage and occasional access only, not living space. Have a qualified professional confirm the two-ply 2x8 beam for this shed width, lumber species and grade, and check its fasteners, hangers, bearing, ledger, floor supports and foundation before building.
  • The truss plates, door hardware and roof metal show placement only. Choose the actual products before construction. Use an engineered truss connection design and follow the selected products' fastening and weatherproofing instructions.
  • Tongue-and-groove flooring and T1-11 siding vary by manufacturer. Check the usable panel size, tongue and groove orientation, structural rating and installation instructions before cutting.
  • Use the plans, drawings and cut lists for your chosen shed size together.
  • Use nominal stock names for purchasing and actual dressed dimensions for layout.
  • Check delivered stock lengths before cutting; full-length pieces have no end-trimming reserve.
  • Follow the selected product instructions for panel gaps, factory profiles, fasteners, flashing and roof laps.
  • Plan wall and roof lifts, temporary bracing, work platforms and fall protection before assembly.
Plan details

12 × 16 gambrel shed

A 192-square-foot gambrel shed with a T&G main floor, wall-supported storage loft, paired end framing, T1-11 exterior and framed double doors.

Choose your shed size to find matching drawings, materials, cut lists, editable CAD and assembly animations. Each complete package includes three printable PDFs. These are unverified design concepts; arrange qualified review of site loads, foundations and structural connections before building.

Open the native FreeCAD file to inspect labeled individual solids and stock properties. STEP contains the same installed geometry for other CAD applications.

CAD dimensions are millimeters; schedules and drawings explicitly use inches. Use the labeled cut-profile coordinates, not printed image scale.

Match this variant and revision across every file. Keep all files for this shed size together.

Instructions

Step 1 Confirm the construction details

  • Use the 12x16 plans and cut lists together. Mark the 144 by 192-inch footprint and the 64 by 72-inch door opening on the project drawings.
  • Obtain the site foundation, anchorage, bracing and framing connection details before ordering affected materials.
  • Resolve loft beam and ledger connections, roof-joint connectors and roof-spread restraint. Keep the loft for light storage with occasional access only after its permitted load and access details are established.
  • Select the actual T&G floor, T1-11 siding, roofing and door hardware; use their product instructions for gaps, laps, clearances and fastening.
Reference drawings:

Check: The required site details, product instructions and fastening schedules are available.

Step 2 Lay out the footprint

Footprint skids
  • Mark a 144 by 192-inch rectangle for the outside floor edges. Label the door end front.
  • Set the front-left floor corner as the datum. Measure X across the door wall, Y toward the rear and Z upward from the finished main floor.
  • Compare the two diagonals and adjust until they match.
  • Mark runner centerlines at X = 5 1/4, 49 3/4, 94 1/4, 138 3/4 inches. Use the foundation drawing for support pads and any supported joints.

Check: All pieces are marked with their matching cut-list IDs and reference edges.

Step 3 Prepare the foundation

  • Prepare drainage and bearing pads using the approved site detail. Remove unsuitable bearing material as that detail requires.
  • Level the support points along and across every runner line. Install the specified anchors while they are accessible.
  • Place a support under every runner end or splice shown in the drawing. Keep the required wood-to-ground clearance.
