Why do the first floors in toudor houses overehang the street?

The overhanging first floors of Tudor houses, known as "jettying," were primarily designed to maximize interior space without increasing the building's footprint. This architectural feature allowed for more room on the upper levels while still complying with street width regulations. Additionally, the overhang helped to protect the lower walls and Windows from rain and debris, contributing to the overall durability of the structure. This design also created a distinctive aesthetic that characterized Tudor architecture.
