The high-rise house is similar to the wide-span structure, but is two-storied.
The birds are on the top storey, with wooden walkways between banks of tiered cages, and no floor beneath the cages.
Manure accumulates on the floor (usually dirt; occasionally concrete) of the first storey.

The first storey is approx. 2.5m high, and is sometimes set below ground level, although it should be slightly above the prevailing ground level to provide drainage away from the house.
The manure is allowed to accumulate in this first storey level for months, or even a few years.
Manure removal is by tractor-mounted front-end loaders.
