Parametric American House Generator (OpenSCAD)

This is a fully parametric American-style house generator built in OpenSCAD. It’s designed to be clean, printable, and actually usable as a base model — not a decorative one-off you’re afraid to touch.

Everything is driven by parameters at the top of the file. Want a wider house? Taller walls? Different roof proportions? Bigger windows? Just change numbers and re-render.

Key Features

True hollow windows
Window panes are open all the way through the wall — no fake “glass slabs.” Muntins span the full wall thickness so it reads correctly in prints and scale models.

Proper front door (with knob)
The front door has depth, a frame, recessed panels, and an optional spherical door knob placed at a realistic height.

First + second story windows
Second-story windows are optional and automatically spaced above the first floor using a configurable vertical gap so nothing overlaps or looks wrong.

Detailed front façade

Framed rectangular windows with sills

Centered front door

Covered porch with columns

Optional column styles (round, square, craftsman)

Gabled roof with hollow attic window
The front and rear gables include a round attic window that is fully hollow, with exterior trim so it still reads visually once printed.

Printable geometry

Reasonable wall thicknesses

No paper-thin decorative nonsense

Boolean cuts are clean and intentional
