Architectural drawing, a foundational element of architectural communication, serves as a bridge between an architect’s vision and the eventual physical form of a building.
This multifaceted tool encompasses a wide range of representations, from initial sketches that capture the essence of a design idea, to detailed construction drawings that guide the actual building process.
Historically, architectural drawing has evolved from simple hand-drawn sketches to complex digital representations, reflecting advancements in technology and shifts in architectural practices.
This article aims to delve into the significance of this in the design and construction process, exploring its various forms, functions, and the impact of technological advancements on its evolution.
Standard Architectural Drawings
There are many types of architectural drawings that are required during the process of designing, developing, and constructing a building, some are used at specific times and stages, and others such as the floor and site plans are continuously evolved and adapted as the project develops.
At their simplest level, architectural drawings ideally comprise of floor plans, sections, sizes and units of measurements, together with references and annotations, however there many additional drawings required depending the scope and complexity of the building.
Survey drawings are often the first type of drawing an architect or designer will work and engage with, and represent a measured and accurate record of the existing site and the buildings occupying it.
This helps the architects to identify existing site levels and features that can be adopted, removed or altered.
Record drawings are made by architects to understand existing projects. For instance, in the renaissance period, architects would create record drawings of buildings that remained after the Greco-Roman civilizations.
They then use these drawings to influence their own designs and projects.
For projects involving renovation or retrofitting, demolition plans indicate parts of the building to be demolished or removed. These plans are essential for understanding the scope of demolition work and ensuring that it is carried out systematically and safely.
Concept Drawings and Sketches
Concept drawings and sketches are quick hand drawings that aim to communicate an idea or notion to help drive a project.
Often initially used internally among the design team, once established they can later be used to help communicate and present the project.
Early in the design process, schematic drawings are used to explore concepts and ideas. They are less detailed than construction drawings and focus on the overall layout, function, and relationships between spaces, serving as a preliminary vision of the project.
Location plans offer a broader context than site plans, showing the proposed development in relation to its surrounding area.
This type of drawing is essential for planning applications and is used to give planners, clients, and other stakeholders a clear understanding of where the new building will sit within the local environment.
It typically includes roads, neighboring buildings, and natural features, providing a comprehensive view of the project’s immediate context.
Site plans are comprehensive drawings that provide a bird’s-eye view of the entire project in relation to its surroundings. They detail the location of buildings, access routes, landscaping, and site-specific features, crucial for planning and executing construction in context.
A floor plan is essentially a map showing a buildings internal arrangement in relation to its external walls and environment.
Each floor or level of the building will require its own plan, which as a rule of thumb is a horizontal slice taken across the building at 1200mm above its floor level.
We have a whole article here, dedicated to drawing one.
In short an elevation is a drawing of an interior or exterior vertical surface or plane, that forms the skin of the building.
Externally an elevation is most commonly used to describe the vertical interface between the interior and exterior of a building, where the external facing walls and surfaces of each side of the proposal are drawn.
A cross-section drawing refers to a vertical, horizontal, or diagonal cut that results in the removal of one of the selected parts to reveal the objects inner elements.
A good example of this is the process of cutting an apple in half to reveal its core and pips, or a cake with all its layers.
Reflected Ceiling Plans (RCPs)
These drawings show the ceiling as if it were reflected onto a mirror on the floor, detailing ceiling elements such as lighting fixtures, HVAC grilles, sprinkler heads, and ceiling finishes.
RCPs are crucial for planning the integration of ceiling-mounted elements with the rest of the interior design.
Electrical, Plumbing, and HVAC Plans
These specialized drawings show the layouts and details for electrical systems, plumbing, and heating, ventilation, and air conditioning (HVAC) systems.
They are crucial for ensuring that these critical systems are integrated smoothly into the building design, providing comfort and functionality for its occupants.
For projects where the external environment is significant, landscape drawings detail the design of outdoor spaces, including plantings, hardscape elements, water features, and outdoor lighting.
These drawings ensure that the building’s exterior spaces are well integrated with the architecture and the site.
A detailed drawing shows a small section of a construction project in detail, and aims to demonstrate how the various elements and materials of a building come together. For example window openings, floor and wall junctions and structural connections.
A comprehensive set that includes all the detailed drawings and specifications for the construction of the building.
These are used by contractors to estimate costs, plan construction sequences, and build the structure. Construction drawings encompass all the above types of drawings, along with specifications for materials, finishes, and construction techniques.
These drawings detail the structural components of a building, such as beams, columns, foundations, and roofs, including materials, sizes, and connections.
Structural drawings are critical for ensuring the building’s stability and safety, complementing the architectural drawings with technical engineering information.
Energy Modeling Drawings
With the increasing focus on sustainability, energy modeling drawings provide insights into a building’s expected energy use and environmental impact.
These drawings are used to optimize the design for energy efficiency, incorporating elements like insulation, window placement, and shading devices.
Created after the completion of a construction project, as-built drawings reflect all changes made during the construction process. They show the building as it was actually built, incorporating any deviations from the original design drawings.
As-built drawings are invaluable for future renovation or maintenance work.
While not drawings in the traditional sense, schedules are an integral part of architectural documentation, listing elements such as windows, doors, finishes, and fixtures, along with their specifications.
Schedules complement the drawings, providing detailed information that helps ensure consistency and accuracy in construction.
Each type of standard architectural drawing plays a specific role in the design and construction process, ensuring that every aspect of the building is thoroughly planned and communicated.
Together, they form a comprehensive documentation package that guides a project from concept to completion.
Architecture drawing scales
All architecture drawings are drawn to a scale and as described here in great detail, there are set scales that should be used depending on which drawing is being produced, some of which are below:
1:500 (1”=40’0”) – Site plan
1:250 (1”=20’0”) – Site plan (note that 1:250 is not a common metric scale)
1:200 (1/16”=1’0”) – Site plan
1:100 (1/8”=1’0”) – Floor plans, elevations and sections
1:50 (1/4”=1’0”) – Floor plans, elevations and sections
1:20 (3/4”=1’0”) – Room plans, interior elevations
1:10 (1 1/2”=1’0”) – Joinery, component details, construction details
1:5 (3”= 1’0”) – Construction details
Architectural Drawing Types
Architectural drawings are not a monolith but a collection of diverse types, each serving distinct purposes throughout the life cycle of a building’s design and construction.
These drawings can be categorized into several primary types, with each playing a critical role in the architectural process. Understanding these types is essential for anyone involved in the construction industry, from architects and engineers to contractors and clients.
Hand drawing is traditional sketching with a pen on paper, but can also be carried out via a drawing tablet. For a long time, architects have used hand drawings to explore ideas and assess multiple options during the design stage.
Unlike today where hand drawings are used to make rough sketches before fine tuning with computer software, traditional hand drawing had to be perfect.
The first-hand drawings in the history of architecture date back to 10,000 B.C.E. At this time the drawings were merely artistic, but then they gradually evolved to become architecturally meaningful.
Today hand drawings have been faded out, but in small instances, they exist side by side with computer-assisted drawings.
Computer Generated Imagery
Computer Generated Imagery (CGI) is as the name suggests the processes of using a computer application to create a representation of a project, with the soul purpose of communication.
As technology has progressed, so have CGI’s, and they now form a fundamental part of architectural presentations and documents at all scales.
Computer Aided Design
Computer-aided design (CAD) is used throughout the entire design and construction process of a project, having completely superseded older formal hand drawing methods.
The advantage among being a lot more precise and accurate, is the ability to revise and undo elements of the drawing with ease and speed, making it a much more efficient method of drafting.
Both architects and engineers use 2D and 3D CAD software. These programs enable in-depth exploration of design ideas. Architects can visualize concepts and simulate design performance in the real world.
Computer-assisted designs are highly beneficial in the construction world. Designers can collaborate over the cloud across oceans. The designs are easy to interpret even for non-professionals.
Presentation drawings are used to communicate the final design to clients, stakeholders, and the public.
These can be rendered in various mediums and styles, from traditional watercolor to sophisticated digital 3D models, and are designed to convey the aesthetic and functional aspects of the project compellingly.
Working drawings, also known as construction drawings, provide comprehensive instructions for the construction team. They detail every aspect of the construction process, from materials to measurements to installation methods, and are legally binding documents within the construction contract.

Architectural Drawing Tips
1. Use line thickness’s – When drawing a floor plan or section, the walls that are being cut through should always be a heavier line weight.
2. Minimize smudging – In order for hand drawn architectural drawings to convey their meaning, they need to be neat. Avoid smudging and making your sketches look messy.
3. Take your time – Creating a perfect architectural drawing takes time. Accept that fact and be ready to rework your pieces for as many times as it takes until you nail it.
4. Use layers – When drawing in a CAD package, divide your line weights into layers, for example you may have different layers for say walls, windows and joinery. These can then be saved as a template and used every time you start a new drawing.
5. Use hatches – Hatches add detail and depth, and can be used to identify and draw attention to elements and materials, for example to show floor finishes and/or light and shadow.
6.Use objects – Using objects such as furniture, cars and vegetation, adds scale and context to drawings as well identifies the limitations of the spaces created. i.e if a client has specialist furniture requirements.
7. Add annotations – Annotations help to draw attention and add additional information to the objects and elements in your drawing.
8. Add dimensions – Dimensions provide a quick reference to the scale and size of the spaces in your drawing, without the need for a scale rule
9. Work with a mouse and not touch pad – To create perfect CAD drawings, you need a mouse, touch screens are not CAD friendly.
