Understanding Architectural Drawings – A Guide For New York Developers

Understanding Architectural Drawings

Architectural drawing is a critical component of the construction design process, helping architects convey their ideas and plans. Whether drawn by hand or generated using CAD software, architectural drawings are essential to ensure that construction projects are realized accurately and efficiently.

Besides floor plans, an architect’s plan consists of other drawings, including site plans, elevations, cross-sections, and detailed illustrations. Understanding the primary categories of architectural drawings will be the central topic of this article.

Site Plan

Site plans are a top-down view of a construction project that shows the current natural and built environments. They also illustrate the size and orientation of a property as well as the position of all existing and proposed structures.

If a property has easements, they should be displayed on the plan, along with the property lines and boundaries. This information helps the city and county check that all structures comply with building codes and zoning regulations before giving them permits.

Site plans may contain several drawing notes varying from blueprint to blueprint. Still, generally speaking, they are grouped into divisions based on discipline, e.g., Division 1 notes refer to general construction, Division 4 notes refer to masonry, etc.

Floor Plan

One of the most essential architectural drawings New York NY in a set of blueprints is the floor plan. It depicts how the rooms are arranged and may contain specifics such as linked cabinetry, wall openings, stairs, vertical circulation, and the locations of fixtures, sinks, and toilets.

A floor plan can also include several notes, legends, and reference symbols that refer to the location of exterior and interior elevation (straight-on view of walls) and cross-section drawings. It may also note the type of construction and dimensions of structural members like beams or columns. Additionally, a scale bar is often shown for measurement reference. It will usually indicate the drawing’s imperial or metric scale. Usually, it can be found at the lower left corner of the page.


Whether you’re designing a skyscraper or a residential home, a comprehensive set of architectural drawings is involved. They include information that communicates design concepts to investors and guides builders in executing construction projects.

These include the plan drawing, elevations, and sections. Elevations provide a vertical picture of a building’s exterior and interior surfaces, whereas plans are flat, two-dimensional depictions of a building’s layout. Sections cut through a building to show interior elements like floor and ceiling heights and wall thicknesses.

Each type of drawing includes standardized symbols and notes to make them easier for construction professionals to understand. They also usually feature the same scale for all pages of a project. Look for general project and discipline-specific notes at the top of each blueprint page.


Whether designing a new skyscraper or a single-family home, an architect follows the same drawing process. They’ll make a set of drawings for the overall project, including elevations, plans, sections, and isometric/axonometric projections.

These drawings are essential for local permitting agencies to review to ensure the final structure meets zoning laws and safety standards. Architects also provide these drawings to clients and construction team members to facilitate coordination during the construction process.

Reading architectural drawings requires attention to detail and a thorough understanding of the building’s components. Look for notes on each page that indicate the location of specific elements. Typically, these notes will be numbered to identify their particular drawing. Also, pay close attention to the scale of each drawing – it will be indicated on the plan’s title page or in the corner.


Architectural drawings are a tool architects and engineers use to plan for constructing new structures. They offer comprehensive elevations, sections, and plans that serve as a graphic depiction of the suggested building. Whether you’re designing a skyscraper or a residential home, creating an architectural drawing set follows the same basic steps.

Interpreting construction drawings requires a keen eye and an understanding of the conventions and symbols used in these documents. It also helps to know about the different types of architectural drawings, such as floor plans, cross-sections, and isometric or axonometric projections.

The plinth beam layout drawing is another architectural drawing that displays every element associated with a building’s structural plan. It is an essential project aspect and must be carefully considered.
