Types of Architectural Expression
plan: A plan, or an architectural plan, is a written and graphic description of a specified building project, usually from an aerial viewpoint. This could include sketches, drawings, etc. There are various types of plans including site, floor, zoning and city.
Ex:
site plan: A site plan could be a plan that details the vision for something such as a park, or a concert site.
floor plan: A floor plan would be a plan that details the vision for the layout or blueprint of a house.
zoning plan: A zoning plan could detail the specific zones or sections of a town, etc.
city plan: A city plan would detail the layout and positioning of buildings etc. around a city.
Elevation: A scale drawing of the external (whether that be the front, back or side) face of a building, from a straight on view.
Section view: A view in which the buildings interior and exterior can both be displayed through an elevation view. This view allows someone to see just the interior of a building, or both the interior and exterior of a building at the same time, while still in an elevation view.
Isometric: A 3D drawing in which 3 sides are displayed with all horizontal lines being drawn at 30 degrees from its base point and all vertical lines being perfectly parallel.
Axonometric: A 3D drawing in which 3 sides are displayed with all horizontal lines being drawn at 45 degrees from its base point and all vertical lines being perfectly parallel.
1 point perspective: All lines in a drawing connect to 1 point, with the drawing having only 1 vanishing point.
2 point perspective: All lines in a drawing connect from 2 points, usually perpendicular to each other, with the drawing having 2 vanishing points.
Filippo Brunelleschi was a famous architect of Italian Renaissance known for his discovery of perspective. This includes the discovery of 1 and 2 point perspectives, views that are still widely used in architecture today.
