What you need to know about 3D Building Rendering

Technology has advanced in recent years by enormous steps and has made strides to convert 2Dimensional drawings into realistic 3Dimensional representations. The term rendering is conversant among architects, engineers, designers, realtors, etc., whose aim is to visualize their creative process to be better appreciated, visually appealing, and easily understood.

This essay aims to demystify the creative process of 3D building rendering to assist architects and designers in preventing many of the frequent pitfalls associated with these new forms of design communication.


Architectural rendering is a process in which an architectural design is created in two and three dimensions. The objective is to depict a real-life experience of how an area or structure looks before it is developed.

Everything starts with the design. Architects interact with clients and consultants to create a building design by working through the conceptual vision.

In many cases, 3D rendering is used early in the design process to make the greatest use of the feedback mechanism and move the design ahead quickly and precisely as feasible. In this sense, it is virtually impossible to carry it out in the “wrong” way. The design process should be developed in such a way that it works for your specific design team. The more data on the project you have, the more accurate your design will be.

At this point in the process, 3D rendering artists should be strictly controlled to generate a picture, an animation, or a digital VR experience that focuses on very specific parts of the design.

So the procedure continues till the desired design is attained. In most situations, design and rendering work continues until the building is finished and occupied. The process is critical because it determines the rigor and accuracy with which the initial concept will be carried out.

Architecture is a discipline where great precision is important. Architects need all the tools they can find to guarantee the completed product is safe and satisfy all the demands of their customers. The greatest advantages of 3D external construction are:

1. Higher design accuracy – individuals can make mistakes in angles and dimensions, even with their years of expertise and their most exact calculations. 3D external representations enable architects to verify the structural integrity and correctness of their design parts.

2. Multi-angle views — Traditional 2D drawings limit the number of angles from which you may examine it, while 3D renderings are not so constrained. For the whole team to grasp the completed result more clearly, multi-views allow you to explain the design with much ease.

3. Minimize building expenses – Since you can immediately discover problems with the building design with a 3D render, you will reduce your total building expenditures. In addition, the building process may be shortened, and the cost can also be reduced.

4. Engaging advertising – architectural renderings are an attractive and appealing method to promote a new building or design. In addition, potential customers are more likely to respond to a complete 3D visualization than to a flat 2D design.

5. Easier Design Changes – Perhaps you determined that the building does not have enough windows or that the entrances are not in the best locations. An architectural rendering will allow all stakeholders to implement design modifications all along the building’s façade with ease.

  •  Aerial Rendering:
    An aerial view creates a dynamic standpoint that provides a better knowledge of the terrain, the structures around alongside detailed views.
  • Interior Rendering:
    This view is supported by details such as floors, furniture, and lighting. Interior renderings indicate the function of a space and how living or working in the space will be like.
  • Exterior Rendering:
    Factors such as light, shadows, and reflection are requirements in the production of an exterior representation. It explains how a building is connected with the environment and its residents.

  1. The Structure:
    The structure is the final focal point of any architectural rendering and should be represented in as much detail as the design allows.
  2. The lighting:
    Lighting is arguably the essential building rendering component to get perfect, depending on the mood or environmental situations the rendering artist is attempting to express. Lighting can enhance or break a scene or experience, especially when striving for photorealism. This is one of the most questionable and prevalent rendering errors, and it may be especially noticeable when crammed into a VR project.
  3. The Texture:
    Towards the conclusion of the rendering process, the texture becomes considerably very essential. Although it may not seem important during the initial phase of rendering, architects and designers should have a concept of the materials and colors they will use from the start. This feature adds an extra touch of realism to the project.
  4. Entourage:
    The entourage of a rendering is the ambient materials and pictures that help reinforce the conceptual meaning of the design. The people, trees, cars, street lamps, and sky conditions that give the building its proper position in the world are all shown here.


Among the most popular applications of 3D rendering is to have architects, construction firms, and clients all on the same design page. The overall objective of every architectural design is to integrate flow with functionality, and being able to view both elements in 3D can assist since it gives you a better spatial concept.


The relevance of 3D rendering in exterior architecture design

The relevance of 3D rendering to any architecture project is irreplaceable. If you check, nothing beats being able to visualize a project even before it has been built in reality or spot problems or issues and fix them in the design phase, averting their occurrence in reality. How about its usefulness in marketing and advertising? It serves as a medium of communication between client and architect in the most straightforward language that both parties can understand.
This article explains in great detail its relevance to architecture.

Sneak-peak into the project in real-time

With the aid of rendering software, it is possible to view a project as if it has already been built, recreating the surroundings and other outdoor elements precisely as it will be in real life. The help of high-definition textures, light effects, color, and other features produces a hyper-realistic image of the project, making it easy to relate with and understand. This makes it very easy for clients to be enticed and attracted to the designs and make purchases because they can see the final output. You will get an image of the project from one view and in multiple views, walkthrough, etc.

Reveals design problems

Sometimes, a paper on paper may seem perfect and flawless but may have some issues that may only be seen when built. 3D rendering takes away that factor as it minimizes such occurrences. It reveals problems that a 2D drawing will never tell. A typical example will be the famous walkie-talkie building in London.

The skyscraper’s unique shape makes it one of the most famous landmarks in the city, but the architect didn’t think about the changing seasons. Its curved shape doesn’t cause any problems most of the time, but the towering side reflects the sun down to the streets for three weeks. That raises the street temperature so much, car tires deflate, plastic parts melt, and people can cook eggs on the concrete.

3D rendering will save the cost of identifying the problems after it has been built and trying to correct it. It ensures the best possible design before construction takes place.

Easier Presentations

3D rendering is a communication tool. They are to present what visual aids are to the classroom. They guarantee effective visualization of the project to investors, clients, etc. 3D rendering helps to show the world the image in the designer’s mind in great detail, much better than drawings and models, especially for designs that are not conventional and difficult to imagine. 3D rendering is the medium we can use to see the future because they look like real pictures. It’s a fantastic tool to blow the mind of the investors and sell designs with ease.

3D rendering is a cost-effective


Before now, in the absence of 3D rendering, architects had to re-design projects by hand when corrections were made to the initial design. It takes about the same time it takes to complete the initial design, and of course, the costs involved were doubled. 3D rendering is a cost-effective way of designing because it allows for almost instantaneous upgrades at practically no cost or even upgrading the buildings in reality.

Marketing prowess

Marketing is a big deal to any business or industry, including the architecture industry, and nothing comes close to closing a deal like 3D rendering. In today’s business world, where everyone is looking for a competitive advantage, 3D rendering proves to be effective when used as an advantage over one’s competition. Your renders have the power to attract the right people depending on the amount of effort you put into it and what you want to achieve. People are attracted to your work based on two significant factors; ability to pay attention to details and what your style represents. With this, you can build a reputation for yourself and attract the crowd that you desire. It is the easiest way to promote a new design or project or even yourself as an architect.

Ease of access to creative juice

Visualizing your design during the design process is a sure way to open your mind up to new ideas and innovations. It will bring you to notice things that you did not initially see or intend, giving you multiple views of the design in progress. Corrections and modifications can be made on the go, and clients can also visualize the project and make inputs. It is so unique that you don’t even have to start over to make these modifications in making changes.

For a 3D exterior render, the building only makes up one part, and the surroundings make up the other part. Otherwise, the building will exist in isolation. 3D rendering allows you to take a few photos of the surrounding area and implement the renders in realistic settings. This is one of the most useful attributes of 3D rendering. 3D rendering takes out trying to create visual images in the mind of what should be and what shouldn’t be and allows everyone to see what the building or design will look like.

Better understanding by building team.

The entire building, including the engineers, surveyors, designers, software professionals, and the client, needs to maintain a good understanding of the project among themselves. The 3D render serves as a language where everyone understands, thus enhancing communication and knowledge in the building team. This also speeds up the design process when everyone is working in sync and at the same pace.

They leverage on the Emotions of Clients

3D renders can look 100% real if done correctly, allowing the architect to evoke emotions from the client or everyone who sees them. Every person likes to appreciate anything aesthetically pleasing, and 3D rendering helps designers leverage this appeal to beautiful things. Nothing can bring an investor closer to a project than a 3D render as they have a lived-in experience of the building or design.


From all angles, the relevance of 3D rendering has been proven without any doubt as a game-changer in the world of architecture. It has simplified the design process from drawing with large sheets by hand to designing small and big scale projects using rendering soft-wares and producing realistic visualizations of the project to be appreciated by everyone.
