Suburb Human settlement that is part of or near to a larger city

A suburb is a mixed-use or residential area, existing either as part of a city or urban area or as a separate residential community within commuting distance of a city. In most English-speaking countries, suburban areas are defined in contrast to central or inner-city areas, but in Australian English and South African English, suburb has become largely synonymous with what is called a "neighborhood" in other countries and the term extends to inner-city areas. In some areas, such as Australia, India, China, New Zealand, the United Kingdom, and a few U.S. states, new suburbs are routinely annexed by adjacent cities. In others, such as Saudi Arabia, Canada, France, and much of the United States, many suburbs remain separate municipalities or are governed as part of a larger local government area such as a county.

City Large and permanent human settlement

A city is a large human settlement. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, and communication. Their density facilitates interaction between people, government organizations and businesses, sometimes benefiting different parties in the process.

It is a relatively modern area with housing stock dating mainly from the late 1980s and beyond. The area has a centralised precinct providing services, comprising a community centre (Thornhill Church Centre), a Sainsbury's supermarket, with an integral Post Office and Pharmacy; and a Medical Centre.

Sainsbury's is the second largest chain of supermarkets in the United Kingdom, with a 16.9% share of the supermarket sector. Founded in 1869, by John James Sainsbury with a shop in Drury Lane, London, the company became the largest retailer of groceries in 1922, was an early adopter of self-service retailing in the United Kingdom, and had its heyday during the 1980s. In 1995, Tesco overtook Sainsbury's to become the market leader, and Asda became the second largest in 2003, demoting Sainsbury's to third place for most of the subsequent period until January 2014, when Sainsbury's regained second place.

Supermarket large form of the traditional grocery store

A supermarket is a self-service shop offering a wide variety of food, beverages and household products, organized into sections and shelves. It is larger and has a wider selection than earlier grocery stores, but is smaller and more limited in the range of merchandise than a hypermarket or big-box market.

There are three public houses located in Thornhill: the Old Cottage, Pendragon, and the Ffynnon Wen. Though on Thornhill Road, The Traveller's Rest to the north is on Caerphilly Mountain and in Caerphilly based on its postcode and council locale.

Most of Thornhill's residential development took place during the 1990s, Cardiff Council originally planned Thornhill as "The Villages of Thornhill"; with clusters of houses interspersed by large "green" areas. These green areas were short lived as rapid housing development resulted in homes being built in areas adjoining the "Villages".
