An estate is a large parcel of land under single ownership, which would historically generate income for its owner.
In the UK, historically an estate comprises the houses, outbuildings, supporting farmland, and woods that surround the gardens and grounds of a very large property, such as a country house, mansion, palace or castle.  It is the modern term for a manor, but lacks a manor's now-abolished jurisdiction.
The "estate" formed an economic system where the profits from its produce and rents (of housing or agricultural land) sustained the main household, formerly known as the manor house. Thus, "the estate" may refer to all other cottages and villages in the same ownership as the mansion itself, covering more than one former manor. Examples of such great estates are Woburn Abbey in Bedfordshire, England, and Blenheim Palace, in Oxfordshire, England, built to replace the former manor house of Woodstock. In a more urban context are the "Great Estates" in Central London such as the Grosvenor and Portman, which continue to generate significant income through rent. 
Before the 1870s, these estates often encompassed several thousand acres, generally consisting of several farms let to tenants; the great house was supplied with food from its own home farm (for meat and dairy) and a kitchen garden (for fruit and vegetables). However the agricultural depression from the 1870s onwards and the decline of servants meant that the large rural estates declined in social and economic significance, and many of the country houses were destroyed.
In modern British English, the term "estate" has been generalised to any large parcel of land under single ownership, such as a housing estate or industrial estate.
Large country estates were traditionally found in New York's Long Island, and Westchester County, the Philadelphia Main Line, Maine's Bar Harbor on Mount Desert Island, and other affluent East Coast enclaves; and the San Francisco Bay Area, early Beverly Hills, California, Montecito, California, Santa Barbara, California and other affluent West Coast enclaves. All these regions had strong traditions of large agricultural, grazing, and productive estates modeled on those in Europe. However, by the late 1940s and early 1950s, many of these estates had been demolished and subdivided, in some cases resulting in suburban villages named for the former owners, as in Baxter Estates, New York.
An important distinction between the United States and England is that "American country estates, unlike English ones, rarely, if ever, supported the house."  American estates have always been about "the pleasures of land ownership and the opportunity to enjoy active, outdoor pursuits."  Although some American estates included farms, they were always in support of the larger recreational purpose. 
Today, large houses on lots of at least several acres in size are often referred to as "estates", in a contemporary updating of the word's usage. Most contemporary American estates are not large enough to include significant amounts of self-supporting productive agricultural land, and the money for their improvement and maintenance usually comes from fortunes earned in other economic sectors besides agriculture. They are distinguished from ordinary middle-class American houses by sheer size, as well as their landscaping, gardens, outbuildings, and most importantly, recreational structures (e.g., tennis courts and swimming pools). This usage is the predominant connotation of "estate" in contemporary American English (when not preceded by the word "real"), which is why "industrial estate" sounds like an oxymoron to Americans, as few wealthy persons would deliberately choose to live next to factories.
Traditional American estates include:
A farm is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops; it is the basic facility in food production. The name is used for specialized units such as arable farms, vegetable farms, fruit farms, dairy, pig and poultry farms, and land used for the production of natural fiber, biofuel and other commodities. It includes ranches, feedlots, orchards, plantations and estates, smallholdings and hobby farms, and includes the farmhouse and agricultural buildings as well as the land. In modern times the term has been extended so as to include such industrial operations as wind farms and fish farms, both of which can operate on land or sea.

Manor may refer to:
A family farm is generally understood to be a farm owned and/or operated by a family; it is sometimes considered to be an estate passed down by inheritance.
The open-field system was the prevalent agricultural system in much of Europe during the Middle Ages and lasted into the 20th century in Russia, Iran, and Turkey. Each manor or village had two or three large fields, usually several hundred acres each, which were divided into many narrow strips of land. The strips or selions were cultivated by peasants, often called tenants or serfs. The holdings of a manor also included woodland and pasture areas for common usage and fields belonging to the lord of the manor and the religious authorities, usually Roman Catholics in medieval Western Europe. The farmers customarily lived in separate houses in a nucleated village with a much larger manor house and church nearby. The open-field system necessitated co-operation among the residents of the manor.
A villa is a type of house that was originally an ancient Roman upper class country house. Since its origins in the Roman villa, the idea and function of a villa have evolved considerably. After the fall of the Roman Republic, villas became small farming compounds, which were increasingly fortified in Late Antiquity, sometimes transferred to the Church for reuse as a monastery. Then they gradually re-evolved through the Middle Ages into elegant upper-class country homes. In the Early Modern period, any comfortable detached house with a garden near a city or town was likely to be described as a villa; most survivals have now been engulfed by suburbia. In modern parlance, "villa" can refer to various types and sizes of residences, ranging from the suburban semi-detached double villa to, in some countries, especially around the Mediterranean, residences of above average size in the countryside.
Hearst Castle, known formally as La Cuesta Encantada, is a historic estate in San Simeon, located on the Central Coast of California.

From the late 1870s to the 1920s, the Vanderbilt family employed some of the United States's best Beaux-Arts architects and decorators to build an unequalled string of townhouses in New York City and East Coast palaces in the United States. Many of the Vanderbilt houses are now National Historic Landmarks. Some photographs of Vanderbilt's residences in New York are included in the Photographic series of American Architecture by Albert Levy (1870s).
A manor house was historically the main residence of the lord of the manor. The house formed the administrative centre of a manor in the European feudal system; within its great hall were held the lord's manorial courts, communal meals with manorial tenants and great banquets. The term is today loosely applied to various country houses, frequently dating from the Late Middle Ages, which formerly housed the landed gentry.
An English country house is a large house or mansion in the English countryside. Such houses were often owned by individuals who also owned a town house. This allowed them to spend time in the country and in the city—hence, for these people, the term distinguished between town and country. However, the term also encompasses houses that were, and often still are, the full-time residence for the landed gentry who ruled rural Britain until the Reform Act 1832. Frequently, the formal business of the counties was transacted in these country houses, having functional antecedents in manor houses.
The North Shore of Long Island is the area along the northern coast of New York's Long Island bordering Long Island Sound. Known for its extreme wealth and lavish estates, the North Shore exploded into affluence at the turn of the 20th century, earning it the nickname the Gold Coast. Historically, this term refers to the coastline communities in the towns of North Hempstead and Oyster Bay in Nassau County and the Town of Huntington in Suffolk County, although the town of Smithtown east of here is also known for its affluence. The easternmost Gold Coast mansion is the Geissler Estate, located just west of Indian Hills Country Club in Fort Salonga, within the Town of Huntington.
A great house is a large house or mansion with luxurious appointments and great retinues of indoor and outdoor staff. The term is used mainly historically, especially of properties at the turn of the 20th century, i.e., the late Victorian or Edwardian era in the United Kingdom and the Gilded Age in the United States.
Idle Hour is a former Vanderbilt estate that is located in Oakdale on Long Island in Suffolk County, New York. It was completed in 1901 for William Kissam Vanderbilt. Once part of Dowling College, the mansion is one of the largest houses in the United States.
William Van Duzer Lawrence (1842–1927) was an American millionaire real-estate and pharmaceutical mogul who is best known for having founded Sarah Lawrence College in 1926 and Lawrence Hospital in 1909. He played a critical role in the development of the community of Bronxville, New York, an affluent suburb of New York City defined by magnificent homes and charming garden apartments in a country-like setting. His name is attached to the Lawrence Park Historic District and real estate brokerage Houlihan Lawrence. Lawrence is buried at the Kensico Cemetery in Valhalla, New York.
