Active Frontage: this is a façade or side of a building that includes windows, doors, balconies and design features that add visual interest from the street. It enables people to see into and out from the building, helping to provide natural surveillance for the street and helping to create a sense of place.

Amenity: this refers to the pleasant or attractive qualities of a place or a building; what an occupant or visitor would expect to enjoy from using that place/building (e.g. natural daylight, privacy, peace and quiet).

Building Line: an imaginary line that describes the physical limit of a row of buildings in relation to a street. It can be uniform, when all buildings are a certain distance from the road, or variable when buildings are staggered and at varying distances from the road.

Boundary Treatment: the way in which the borders of a property or space are defined using physical structures or features such as fences, walls and hedges.

Character: this is the combination of matters such as: land uses, the design and layout of buildings and public spaces, typical views and other distinctive features such as local topography and natural greenspace, which come together to make one place feel different and function differently from another. 

Context: this is the setting for a building or a development site, which is influenced by surrounding land uses, any notable landscape features, and (more broadly) the character of the surrounding area.

Curtilage: this is the area of land immediately surrounding a house or other building that is associated with the use of that house/building. It includes the garden and driveway and is usually defined by physical boundaries. Ancillary buildings are often located within the curtilage of a house.

Density: in design terms, this is the number of buildings or amount of floorspace for a given area of land.

Elevation: this is a side-view perspective of a building, from the exterior.

Fenestration: this is the design and placement of openings (windows and doors) in a building.

Habitable Rooms: this is a room that is used for dwelling purposes, but which is not solely a kitchen, utility room, bathroom, cellar or sanitary accommodation.

Mass: the mass of a building is how massive it appears on the basis of its perceived size, shape and form.

Natural Surveillance: the informal and incidental observation of people in public areas.

Overbearing: the impact of a building on its surroundings in terms of its scale, massing and general dominating effect.

Overshadowing: the impact of a building on its surroundings in terms of the effect that its scale, mass and height may have on blocking out daylight and sunlight for nearby properties.

Private Amenity Space: this is outside space that is associated with a dwelling and is for the enjoyment and benefit of residents, protected from public view by the design of the dwelling/boundary treatments.

Solid-to-Void Ratio: this is the ratio of the sum of the areas of window and door openings to the gross area of an exterior wall of a building.

Streetscape: this is the physical features that comprise how a street appears (the road, external facades of buildings, pavements, street furniture, trees, verges and open spaces).

Street scene: the appearance of a street, including the building frontages where these are visible, from a certain perspective.
