One body. Infinite houses.

Every cavity house is four parts that snap together. The body and roof outlast everything; the front and entrance are swappable. Change a single 25-gram entrance and the same house retargets from chickadee to bluebird to swallow.

01

Body

The structural shell. Three walls, floor, drainage, vent slits. Same body fits every front and entrance combination at its size.

02

Front

The face plate. Slides into the body and locks with two screws. The skin you change for a different look or finish.

03

Species Entrance

A 25-gram tile with the species-targeted hole. Drops into the front's window. Swap this one part to retarget the house from chickadee to bluebird to swallow.

04

Roof

The lid. Flat slab through-bolted to the body, with a clearance notch for the back-wall hanger. Lifts off for cleaning between seasons.

Limited Drops

New panels every season.

The body is the canvas. Every drop is a new panel, themed, limited, and tied to a conservation cause. Subscribers see the drop calendar first.
