A single-pitched roof can be a smaller addition to an existing roof, known in some areas as a lean-to roof, and a "outshot", "catslide", or skillion roof in others. Some Saltbox homes were expanded by the addition of such a roof, often at a shallower pitch than the original roof. Single-pitched roofs are used beneath clerestory windows. Modern ...
A lean-to is originally defined as a structure in which the rafters lean against another building or wall, also referred to in prior times as a penthouse.

Lean approach tries to make continuous improvements in the process, workflows and product; [19] whereas PMI approach doesn't pay that much attention to continuous improvement. In lean construction, decision making is distributed in design production control systems; [20] by comparison, in PMI decision making is centered to one manager some times.

In his "Treatise on Mills and Millwork", of 1863, Fairbairn stated that, "Contemporaneous with the architectural improvements in mills [from 1827], the shed principle lighted from the roof, or the "saw-tooth" system, came into operation.
