Sometimes the site plan can be drawn as a first floor plan being cut through the first floor. A site plan will most typically be drawn from above the building, as if showing a roof plan of the building within the site plan. This can show the property lines, the building location, utilities, roads, landscape etc. A site plan is going to show more than just the building, including the entire site the building is located on. Site PlanĪ site plan may or may not be drawn cutting through the building. Plan details are drawn in a plan view at a large scale to show the construction. Details are normally 3/4″ = 1′-0″ or larger. Details identify all the materials and connections for construction. Plan Detailsĭetails in architectural drawings are large scale drawings that typically show how something is built. Half inch scale is twice as large as quarter inch scale. For example, if I have a floor plan at 1/4″ = 1′-0″ scale of a house, I might have a callout of the kitchen and bathrooms, showing them at 1/2″ = 1′-0″ scale. A callout is an area within the plan that is drawn at a larger scale. Plan CalloutsĪnother common architectural convention is the use of plan callouts. Therefore, you see in the cut anything that the plane passes through.
This means that you have an imaginary plane cutting through the building at an elevation of 4 feet above the floor. The plan is typically cut at a height of about 4 feet, but the architect drawing the plan may cut it at a different height.
Although plan drawings can be drawn from above, they are often drawn cutting through the building with horizontal plane. This is often used to depict the layout of a building, showing locations of rooms and windows, walls, doors, stairs etc. There are different types of plan drawings:Ī plan drawing shows a view from above. This means they are not drawn in perspective and there is no foreshortening. With the exception of plan perspectives, plan drawings are orthographic projections. Plans are a common design drawing and technical architectural or engineering convention for graphic representation of architecture. This is as if you sliced through a space horizontally and stood over looking down on it. A plan is drawn from a horizontal plane looking down from above. Plan drawings are specific drawings architects use to illustrate a building or portion of a building. In this post, I will review some of the basic concepts of architectural drawing. I am Jorge Fontan, an architect in New York and owner of Fontan Architecture. A section drawing is also a vertical depiction, but one that cuts through space to show what lies within. An Elevation drawing is drawn on a vertical plane showing a vertical depiction. A plan drawing is a drawing on a horizontal plane showing a view from above. Plan, Section, and Elevation are different types of drawings used by architects to graphically represent a building design and construction.
