Architectural Concept Drawings Process and Types

Architectural concept drawings are a crucial step in the design process, allowing architects to visualize and communicate their ideas effectively.

These drawings are typically created during the initial stages of a project, before any construction begins.

A key aspect of architectural concept drawings is their ability to convey the overall vision and aesthetic of a building.

Concept drawings can be created using various mediums, including traditional hand-drawn techniques and digital software.

They often serve as a starting point for further design development and refinement.

Visual communication tools are essential for architects to convey their ideas and designs to clients and stakeholders. Architects prepare two-dimensional drawings such as conceptual site plans, architectural floor plans, exterior elevations, and interior elevations to illustrate the spatial configuration and relationships of rooms and spaces.

A conceptual site plan is a top-down view of a property that shows important features like utilities, roads, and mature trees. Architects evaluate factors like solar orientation and topographical features to site and design structures.

Architectural floor plans are detailed drawings that show the intended spatial configuration and adjacencies of each room on each floor of a building. They are often initiated as hand-drawings and sketches before being advanced into computer-aided drafting programs.

Exterior elevation drawings show the outline, proportion, and shape of buildings, including door and window sizes and locations. They are often hand-drafted before being input into computer-aided drafting programs.

Interior elevation drawings illustrate the visual architectural intent and spatial relationships of doors and windows, built-in furniture, and detailed millwork.

Building section drawings represent a theoretical vertical slice through buildings to illustrate volumes, ceiling heights, and spatial relationships of interior and exterior spaces. They are prepared to better understand the structure's relationship to the adjoining topography.

Architects use three-dimensional visualizations like perspective drawings, sketches, and models to represent complex design concepts. They employ computer-aided drafting software programs like Revit and SketchUp to generate three-dimensional graphic representations.

Digital graphic tools like Lumion and Photoshop are used to render three-dimensional computer-aided building models to an extraordinary level of detail. Physical 3-D small-scale models are sparingly prepared by architects to represent architectural concepts where digital and graphic 3-D representations are not adequate.

You don't have to be an artist to draw architecture diagrams. An intelligent diagramming app like Lucidchart makes it easy to create architecture diagrams and share with your team or stakeholders.

Lucidchart has a large library of templates to help you draw any type of architecture, including network diagrams, AWS cloud architecture templates, software component diagrams, and more.

Templates make it easy to jump right in and get your projects off the ground quickly.

An architectural concept drawing is prepared by an architect as per the client's brief for initial discussion. This drawing indicates the basic layout with approximate sizes of rooms, setbacks, and circulation areas.

The client is free to give suggestions and can request changes to the drawing. The architect makes necessary changes as per the client's further suggestions and takes approval from the client.

Only after the client's approval does the architect move to the next stage of architectural detail drawing.

Drawing techniques play a crucial role in architectural concept drawings.

Perspective is a fundamental technique used to create the illusion of depth on a flat surface.

One-point perspective is commonly used to depict buildings and streets, while two-point perspective is often used for more complex scenes.

To create a convincing one-point perspective, the vanishing point should be placed at eye level, about one-third of the way down from the top of the page.

Two-point perspective, on the other hand, requires a horizon line that's placed at a slight angle to create a more dynamic feel.

Line weight and texture can greatly enhance the visual interest of an architectural concept drawing.

A range of line weights can be used to convey different materials and textures, such as the smoothness of glass or the roughness of concrete.

The use of hatching and cross-hatching can also add depth and dimension to a drawing.

In addition to line work, color can be used to add visual interest and emphasize specific design elements.

A limited color palette can create a cohesive and harmonious look, while a bold and bright color scheme can make a statement.

The concept and preliminary drawings are two crucial stages in the architectural design process. The architect prepares the concept drawing as per the client's brief for initial discussion.

This drawing indicates the basic layout with approximate room sizes, setbacks, and circulation area. The client can freely give suggestions and request changes.

The architect makes necessary changes to the concept drawing based on the client's further suggestions and takes their approval before moving forward. Only after the client's approval can the architect proceed to the next stage.

After approval of the concept drawing, the architect prepares preliminary drawings. These drawings include plans, elevations, sections, and sometimes a furniture layout to give an idea of how furniture will be placed in each room or space.

The preliminary drawings also provide an idea of the parking area, garden area, play area, and other site development.

Regulatory drawings are a crucial part of the architectural process, and they include sanction drawings and tender drawings. Sanction drawings are required to be submitted to the authorities, and they must include site layout, floor plans, elevations, and sections in the required format and scale.

These drawings must also mention the owner's details, site details, adjacent properties, survey numbers, and the architect's details, including their COA number. This information is essential for obtaining the necessary permits and approvals.

Tender drawings, on the other hand, are prepared for contractors to understand the project completely, and they include bill of quantities and specifications for tenders.

Sanction drawings are a crucial part of the regulatory drawing process. They include site layout, floor plans, elevations, and sections in the required format and scale as per authorities.

The format and scale of sanction drawings are strictly regulated, and failure to comply can result in delays or even rejection of the plans.

Sanction drawings must also include owner's details, site details with adjacent properties, survey numbers, and the architect's details with Council of Architecture registration (COA) number.

This information is essential for authorities to verify the authenticity and validity of the plans.

Working drawings are the expansion of tender drawings, providing detailed technical information about a project. They're essential for construction site execution.

These drawings include a range of documents, such as site plans, center line drawings, and foundation plans. A site plan, for instance, outlines the building's location and surrounding features.

Center line drawings and foundation plans provide critical information about the building's structure. Foundation plans, in particular, detail the building's footprint and the location of its foundation.

Detailed floor plans and elevations offer a more in-depth look at the building's layout and design. Detailed sections, on the other hand, show the building's internal structure.

Working drawings also include staircase details and door and window details. These details are crucial for contractors to understand the project's requirements.

Here's a breakdown of the various components that make up a set of working drawings:
