A single toilet is a building or a structure

The simple way to identify what is a building and what is a structure is that it is a building where people can enter and move, and what people cannot enter and move is a structure. Because the Code for Fire Protection Design of Buildings and the Code for Fire Protection Design of High-rise Civil Buildings are used for buildings rather than structures. The second is whether the structure should be designed for fire protection (e.g. garbage room, etc.).

The concept of buildings in a broad sense refers to all artificially constructed structures, including both houses and structures; A building in the narrow sense refers only to a house and does not include structures. Housing refers to the space composed of an envelope structure that can shelter from the wind and rain for people to live, work, produce and live, entertain, store items or carry out other activities. For example, residential buildings, apartments, dormitories, offices, shopping malls, guesthouses, hotels, theaters and other structures refer to buildings other than houses, in which people generally do not carry out production and living activities.

Such as chimneys, wells, roads, bridges, tunnels, dams, etc. The building referred to in architectural design usually refers to a chivalrous building.

After knowing the concept of buildings and structures, we at least know that buildings must be designed for fire protection, because to ensure the safety of people and property, structures generally do not need to be designed for fire protection, such as garbage rooms, chimneys, wells, roads, bridges, dams, etc. Whether all structures do not need to be designed for fire protection should be treated on a case-by-case basis. Such as surface parking lots and tunnels, etc., single function, belong to the structure, once a fire will also affect the safety of personnel life and property, so should also be designed for fire protection, there are special supporting "parking lot fire protection design code" and "tunnel engineering fire protection design code".

In summary, a single toilet is a building.

Buildings are commonly referred to as buildings, which belong to the category of fixed assets, and generally refer to engineering buildings for people to live, work, study, produce, operate, entertain, store goods and carry out other social activities. For example, industrial buildings, civil buildings, agricultural buildings, and garden buildings, etc. What is different from a building is a structure, which refers to an engineering structure other than a house, such as fences, roads, dams, wells, tunnels, water towers, bridges, and chimneys.

Normally, the so-called structures are artificial structures that do not have, do not contain or do not provide human habitation functions, such as water towers, pools, filter tanks, clarifiers, biogas digesters, etc. Artificial structures that generally have, contain, or provide human habitation functions are called buildings. The title of the structure is mentioned a lot in the textbooks of water supply and drainage.

It should be noted that this definition is not absolute. In water conservancy and hydropower projects, all structures on rivers and channels are called buildings, such as hydraulic buildings.

From the above two definitions, toilets belong to buildings that provide functions for human life.
