How Do Architectural Design Firms Use Space Planning to Visualize 3D Floor Layouts?

3d floor plan rendering services

This article covers how architectural design firms use space planning to visualize 3d floor layouts. When your architectural drafting firm receives the first iteration of a new project’s 3D interior design brief with a list of requirements, many questions arise. But out of all these questions, one fundamental question tops them: how will the space be lived in and used? This is where space planning enters the picture. This article delves into space planning in visualizing 3D floor plan layouts. 

What is space planning?

Space planning refers to identifying the proposed uses of a space or spaces in architectural projects. Space planning must be carefully based on the functional requirements of the client. This is also the perfect chance to integrate space planning as a critical element of the project’s architectural concept. Aside from serving as an interpretation of the desires and preferences of the client, space planning also comes with more questions about the design that should also be considered. What type of space is in question? Will it be for private or social use? Is a storage area required? Will it involve resting or working?

These questions might have challenging and complex answers. For instance, a room may be used for working and resting, and at the same time, a storage area may also be necessary. Spaces with multiple functions will also trigger more considerations for the overall design and 3D floor plan rendering services. The different anticipated activities in a particular space will also affect choices like exterior and interior entrances, access to the rest of the rooms, and lighting, to mention a few. 

Importance of space planning

Have you ever experienced cooking in a poorly designed kitchen? The cleaning and cutting areas may be too cramped, while the distances between the sink, stoves, and fridge are too long. It could also be that mold formed because of the wrong finishing material for the counter or inadequate ventilation or natural light in the room. All of these can make the space uncomfortable, which eventually leads to discoursing its use altogether. 

Space planning is essential for 3D interior rendering firms because it allows them to foresee and fix these design issues before they become serious problems. The goal of space planning is to make the interior design invisible. Once the users start living in the space, they should be able to do it intuitively and fluidly. When you ask the right questions and make the right decisions based on them, you can expect results that will be more appreciated and enjoyed by those who will use and live in them.

What does space planning influence?

Regarding design, space planning also influences a series of choices in an architectural project. The following are some of the main categories that space planning influences, together with several vital decisions they may trigger:

Layout options

These options consider the rooms’ adjacency, relative size, connivance and continuity between them, the circulation in the space, balance and main focal points, and privacy levels. It also involves the physical and visual need for connections with the outdoors, the arrangement of required furniture and fixtures, the placement of windows and doors, and the flexibility of the original scheme for future growth. That’s why it pays to invest in professional architectural planning and design services.

Lighting options 

Considering the anticipated use of every space, it’s also critical to identify the levels of artificial and natural lighting, the disposition and selection of appropriate lighting artifacts, and the arrangement of places for light and electrical plugs. 

Material options 

Continuing with the example above, it deals with correctly identifying the finishing of humid zones and work surfaces, the flooring in terms of expected visual and transit perception of the space, and the materials and colors of decoration and walls. 

Technical options

These mainly pertain to aspects of sustainability and climate comfort, such as room orientation, the requirement of technical spaces for air conditioning, and decisions regarding legislative and budget requirements, including the disposition of rooms in one or a few stages. It also involves space accessible to people with disabilities.

How the space planning process improves 3D interior design rendering strategies 

Thoughtful and good space planning allows 3D interior visualization experts to add more complexity and depth to an architectural concept. If you always use the requirements and existing conditions as an opportunity rather than a restraint, space planning can make your 3D interior design rendering strategy thrive and stand out. 

Space planning often begins with the so-called bubble plan. A schematic plan diagram delineates the different functions to be accommodated in the 3D floor plan layouts. The iteration is usually progressive, from the general down to the specific. The bubbles start vague, with interest given only to how they are related to each other. From there, the focus shifts to the shape and size of each one. 

Once the layout feels comfortable enough, it’s time for the 3D floor plan design firm to sketch a floor plan with provisional furniture, fixtures, and walls. It can be manually done using movable paper cutouts and pen or 3D floor plan layouts. In this case, 2D drawings and floor plans or 3D floor plan design renderings are more suitable for faster and more flexible work. Dimensions and square footage will now be more precise for every space.

The preliminary floor plan will serve as the basis for the rest of the new decisions concerning the furnishing and interior lighting of spaces, the location of doors and windows, and the designation of floor materials. This is also typically when you triangulate with sections, render mockups, and sketches to evaluate the appearance of the different decisions on design.

Fundamental principles of space planning

Space planning has five fundamental principles that 3D floor plan designers take into consideration when visualizing 3D floor plan layouts, and these are the following:

Try to have a margin all the time

Sometimes, getting the best out of the available surface can be too tempting. Unfortunately, it may result in an overcrowded floor plan with many small spaces. Regarding legislative conflicts or restraints with pre-existing conditions, it will be better to allot a square footage reserve that lets you make the spaces more architecturally exciting and human.

Have a clear list of the priorities and requirements of the clients

When you move a piece in a game board, something will always change in the rest of the pieces. It will help to take note of the most critical points and keep them handy to save you from the trouble of juggling them in your head when going about with the 3D floor plan design.

Prioritize the efficiency of square footage

A vast space will be useless if 50% of the floor will be corridors that look like labyrinths and mazes. Circulation must be synthetic and transparent to offer the best moving experience possible. 

Let the sun in

For climate comfort and lighting alike, the position of every space when it comes to sunlight opening will significantly affect the final 3D floor plan design. Whether the architectural drawing professional incorporates the best indirect illumination or catches the cozy morning sun, window proportions and room orientations play a crucial role.

Always consider the whole when designing a part

Although the kitchen may already be flawlessly functional on its own, the experience of its usage might be completely ruined if it is right beside the main bedroom. Always consider the relationship between the different spaces, how they are linked, their usage’s contradictory nuances, and the specific activities they are meant to host. 

Factors for space planning 

Space planning may trigger a series of 3D floor plan design options. These are mostly made up of material, lighting, technical, and layout choices. Here are other factors that must be taken into consideration when using space planning to visualize 3D floor plan layouts:

  • Accessibility 
  • Economy 
  • Existing patterns of circulation 
  • Existing features
  • Function 
  • Light 
  • Site
  • Size 
  • Storage
