Architectural Schematic Design: How Bubble Diagram Improves Space Planning

Space planning in architectural schematic drawing has transformative power. A built environment created with reference to a messy design draft always makes things worse.

There would be reworks during the construction, or even after the construction is finished, hiccups will arise during the operational phase of the same.

Hence, space planning is a critical aspect of the architectural realm, where it ensures the smooth functioning of a building.

This is done by optimizing layouts and spatial relationships, ensuring the user’s expectations are met.

Organizing the interiors is another critical aspect that architectural planning contributes to. The visual map helps in imagining the elements and their spatial relationships.

It allows for finding the proper spaces, where things can be placed, and that will contribute to efficient space usage.

A bubble diagram is the visual map we are talking about here, which helps improve the space planning in architectural schematic design.

Architecture planning is a process that includes tons of revisions and the use of tools and methodologies. However, the bubble diagram refines the outcome of that hefty process, providing a solid and tangible plan, which can be acted on.

So, let’s see what bubble diagrams are at their core.

Bubble Diagrams- The Detailed Definition

Bubble diagrams are freehand diagrammatic drawings created with lines and circles (that actually look like bubbles). Each of these represents the specific function of that area, whether it is in floor plan format or landscape architecture plan.

The technique is simple and contributes a lot to making the process clearer. However, it is still undervalued in the industry.

Bubble diagrams provide intuitive visuals that become the foundation of spatial planning. It enables the designers involved in the project to better communicate their design intent.

After the zoning phase is over, bubble diagrams come into play. They show the connectivity between each zoning, helping in understanding the operational movement across various zones.

Bubble Diagram- Basic Elements in Architecture

So, by now, we have briefly uncovered bubble diagrams, understanding that they consist of bubbles that represent different spaces in a structure along with their functionality. These bubbles are then connected with lines to understand the spatial relationships.

Let’s now unravel the different components available in a bubble diagram and their significance.

• Bubble Sizes: The bubble sizes represent the significance along with the scale of a particular space. For example, in a residential bubble diagram, living and main areas are drawn bigger, while areas reserved for storage and service rooms are drawn smaller.
• Bubble colors and Line types: Once the bubbles are drawn, they are separated by colors and lines. It gives a detailed and clearer understanding of the spatial planning. There is no hard and fast rule for selecting the colors; hence, the living rooms may be marked with yellow, the bedrooms in green, and the lounge area in red.
• Labels and Symbols: These are the elements used to name the spaces and add the features. For example, furniture placements, light fixtures, and directional cues are also used. Further, if the diagram is a bot more complex, additional shadings or patterns are also used for maybe the outdoor spaces, private areas, or cafeterias.

These elements, when used appropriately, help the architects understand the spatial organization, the zonal functions, and the complete design.

Now, as the bubble diagram is a critical component in space planning, let’s understand what is the importance of space planning.

Importance of Space Planning Across Disciplines

Space planning involves curating a strategic approach to optimize space usage and ensure optimal functionality of a structure during operation. It further ensures safety and accessibility, which are very critical in today’s AECO area.

• Architecture and Interior Design: When planning the interiors, there are several aspects to consider before executing a plan. The elements include aesthetics, layout, lighting positions, and overall accessibility of various parts of the room. Space planning helps in understanding and clarifying how all these aspects would work together in harmony, and also meet the user’s expectations. Designers consider traffic flow, natural light, acoustics, and ergonomics to create environments that give relief to their residents after a tiring day.
• Urban and Regional Planning: Space planning plays a significant role in bringing better sustainability edges to urban and regional planning. Since this is on a larger scale, proper planning leads to efficient land usage, ensuring that municipalities and regions can sustain and grow in a structured manner. It helps in streamlining the demands that these areas pose, such as commerce, green spaces, and transportation, which results in economic development and smooth adaptation to climate change.
• Facility and Workspace Management: These are spaces where efficient space management leads to several positive outcomes, like cost efficiency and employee well-being. Bubble diagrams help plan the space better and promote fair usage of space. Even in healthcare facilities, where every corner and every equipment affects someone's life, space planning is immensely important.
• Landscape Architecture: Landscape architecture heavily uses space planning principles for productive use of land, to reduce environmental impact, all while maintaining the aesthetics. The same principles help them understand where certain vegetations will fit, and where hardscape features would be a good fit.

You read space planning principles, but what are those, and how does following each of those make space planning better?

Core Principles of Space Planning

While space planning shows its use across sectors, these core principles form the reliability and effectiveness of this approach. These are:

• Functionality and Purpose: Whatever the planning is, the space should serve the aimed purpose effectively.
• Flow and Circulation: Whether it is a healthcare facility, residential property, or educational hub, the operations and movement inside the space should be logical and free-flowing. There should not be any adjustments made; everything should feel natural.
• Flexibility and Adaptability: The spatial planning should be made keeping in mind the future accommodations and growth. While an organization experiences growth, there would be additional equipment, manpower, and cabins for designated people. Incorporating these later should not be a challenge; rather, it should be a smooth task. All this depends on how professionals plan the space for changing setups and growth.
• Health, Safety, and Well-being: Space planning also needs to follow building codes and accessibility guidelines. When done by professionals, they ensure spaces that promote mental and physical well-being.

Now, these are the core principles of spatial planning. We will now see the advantages and disadvantages of bubble diagrams in architecture.

Why Use Bubble Diagrams

Though the technique is underrated, it has found constant relevance amongst architects worldwide, who are looking for simplicity and effectiveness.

Quick and Time-efficient

Bubble diagrams are quick to prepare, with only three elements in action. Those are the bubbles, the lines, and the colors in today's advanced software tools.

They also simplify complex designs and architectural drafts with advanced features into captivating visuals that save a lot of time that would otherwise go into analysis and communicating advanced design intents.

Faster Concept Planning

During the planning of a concept, most of those are prepared through detailed architectural drawings.

Even in the conceptual phase, such drawings require a significant amount of time to be finalized and communicated effectively to other project stakeholders.

Bubble diagrams make this task a lot easier, letting architects start with simple, hand-drawn sketches that are faster to create than detailed drawings.

Quick pattern identification

Bubble diagrams play an important role in eliminating the need for hefty documentation reviews. The size of the bubbles, their colors, and position easily help stakeholders understand patterns, trends, and the top priorities at a glance.

Hence, these are more suitable for quick concept finalization and proceeding to the next stage of work.

Better Decision-making

Bubble diagrams present the information clearly with the areas highlighted separately through different elements. These are colors, patterns, and bubble sizes, which makes understanding clear and team collaboration better. And hence, decisions are taken faster, and any revisions are communicated back and forth more effortlessly.

Easy rooms/space categorization

Interior designers need to categorize rooms and spaces based on their use and privacy. Whether in corporate setups or residential properties, a bubble helps in better categorizing the rooms.

Bubble diagrams facilitate a better understanding of the circulation needs as well, and plan better in the initial phases, which reduces the rework afterwards in the process.

Visual representation

Architects need to communicate their ideas effectively in the initial phases. This is because they are the ones whose work will be setting the path ahead. The first time communication of the ideas is a hefty work, because that’s the first time.

With typical architectural drawings, clients and other stakeholders remain ambiguous and aren’t one hundred percent sure about the design. Many doubts still remain, which arise later, making the process more complicated.

Here, bubble diagrams make the work easier for architects in the initial stages. They help them communicate the ideas effectively, ensuring that the initial phase goes smoothly.

Now, let’s look at the disadvantages of bubble diagrams. And here comes the real game, the reason why these are so helpful, but still cannot get an architect’s attention.

Disadvantages of Bubble Diagrams

While bubble diagrams enhance clarity and communication, they do not have any technical specifications. These are hand-drawn sketches and only show the spatial relation and the areas along with their functions.

Do not convey actual design language

Bubble diagrams are better at showing relationships and proximity; however, they do not convey any technical details. For example, a cafeteria and a conference hall may look the same, and theory does not provide any sense of volume and height.

These diagrams also do not show the geometry and other technical details of the space. While an architectural drawing may take time, it shows these intricate details.

Absence of Material Specifications

Bubble diagrams are simple hand-drawn sketches, and they do not allow the display of materials and aesthetics.

They only give a clear idea of the directions and spaces where different spaces would be. The material palettes, color schemes, lighting logics, or wall articulation; bubble diagrams do not convey any of that.

They lie to you by design

While creating bubble diagrams, designers get a lot of flexibility. Many things can overlap, compress, or stretch in such designs.

However, when that bubble diagram is converted into actual architectural drawings, the reality hits hard. This is because structures require accurate and fixed dimensions, rather than assumptions.

In reality, even a door swing matters, and furthermore, there are building standards with which the buildings need to be in compliance for the restructure to be successfully completed.

Shifting from a bubble diagram to a plan is difficult

Architects face huge difficulties while transforming a bubble diagram into an actual architectural plan. While bubble diagrams can give a clear idea of where everything will be situated, there is no technical data associated with them.

On the other hand, architectural drawings include fixed dimensions and spatial relationships. Therefore, the idea from a bubble diagram can impossible be directly translated into a plan.

Architects need to rethink the design and then start with the plan, which requires fixed dimensions, materials, and sizes.

Where do Bubble Diagrams Fit?

Bubble diagrams are not good enough because the designers cannot effectively translate them into actual designs. They do not have fixed dimensions and are not prepared, keeping in mind the geometry of the spaces.

Hence, they find a perfect fit during early-stage thinking. This is the stage where the concept of the complete space is thought out and finalized.

These diagrams do not go a long way in the construction of the design process. They are perfect for a one-time use, where just the relationship and proximity between spaces are conveyed.

The design process only begins with actual architectural drawings.

Wrapping Up

Bubble diagrams are the first choice of architects because of their low accuracy and lack of technical details. They serve the best when architects convey their thoughts on the design in the very initial phases.

It comes in between the architectural drawing and the architect’s initial thought process. Architects, while conveying their initial thoughts on the design, would not be comfortable preparing a detailed architectural drawing. Because that is only the starting phase, and there will be a number of changes ahead.

So, here they can use a Bubble Diagram to communicate their thoughts effectively, and on approval, they can start with the architectural drawings.
