Incomplete cost and uncalculated work
No prices entered.
No market prices; costs omit labor, delivery, utilities and unpriced items.
- Foundation, footing and anchor engineering
- Snow, wind, seismic loads and member sizing
- Connection capacity and fastening design
- Electrical systems and drainage engineering
- Labor, delivery, unpriced materials
- Post/beam/rafter connections and floor-panel fasteners
- Railing infill, privacy-wall backing and roof longitudinal overhang support
- Header/jamb redesign at openings; nominal studs are not removed
- High-wall and roof-end infill framing
- Geometric cladding/covering stock layout
Template and calculation assumptions
- Member spacing includes both endpoints. Different profiles use independent stock pools.
- Openings subtract cladding, not structural members. Header/jamb framing is not designed.
- Fasteners follow editable per-connection/per-panel assumptions; preliminary quantities only.
- Roof slope is measured across width; ridge runs along length. Overhang extends projected roof on all sides.
- Shed wall height is measured above floor level; gazebo eave height is measured above post base. Entrance width is clear between post faces. Railing quantities include two horizontal rails, without balusters or hardware.
- Board counts include a full-width final board for trimming. Panel grids do not reuse offcuts between planes.
- Cladding fasteners use a rectangular fixing grid at the editable stud/fixing spacing in both directions, including endpoints on full wall bounding boxes; openings are not deducted. This is a conservative preliminary assumption, not connection design.

Example and dimensions
Editable example: 4 × 3 m, wall height 2.4 m, 50 × 100 mm nominal framing, 0.6 m stud/rafter/joist spacing, one 0.9 × 2 m door, 25° roof and 0.25 m overhang.
Required inputs
External dimensions, framing section, stud spacing, roof/slope, wall cladding, floor layout, door/window locations, optional partition, material profiles, roofing usable/physical dimensions, reserve and optional user prices.
Formulas and assumptions
Clean dimensions exclude framing depth on both sides. Disjoint wall rectangles and optional partition define zones. Door/window rectangles must fit and not overlap; openings subtract cladding, while nominal studs remain in the quantity reference grid. Roof-end cladding infill is geometric only. Floor boards run along length; joists span width. Both member endpoints are included.
Geometric consumption, parts, stock, offcuts, kerf and user reserve are separate. Stock without a layout algorithm is NOT_CALCULATED. Fasteners are preliminary estimates from explicit spacing and connection-count assumptions. Prices come from the user; labor, delivery, utilities and unpriced items are excluded.
Limitations
SHD-01 is mono-pitch storage with one door and no windows/partition. SHD-02 has a gable roof, floor and optional windows. SHD-03 has a gable roof, floor and storage/work partition. Header/jamb and upper-wall framing redesign, foundation engineering, loads and connection capacity are uncalculated.
