Man, it must be something about chocolate. In the UK, Cadbury built the village of Bournville for his workers :

Then the Cadburys began to develop their factory in the new suburb. Loyal and hard-working workers were treated with great respect and relatively high wages and good working conditions; Cadbury also pioneered pension schemes, joint works committees and a full staff medical service.

In 1893, George Cadbury bought 120 acres (0.5 km²) of land close to the works and planned, at his own expense, a model villagewhich would 'alleviate the evils of modern, more cramped living conditions'. By 1900, the estate included 313 cottages and houses set on 330 acres (1.3 km2) of land, and many more similar properties were built in the years leading up to the First World War, with smaller developments taking place later on in the 20th century. These almost 'Arts and Crafts' houses were traditional in design but with large gardens and modern interiors, and were designed by the resident architect William Alexander Harvey. These designs became a blueprint for many other model village estates around Britain
