Insights of things that we care about
Since time immemorial, real estate- from the humblest houses to giant pyramids have been more than places to live, or even rest in death. They were statements- of power, imagination, personality. Think of the Taj Mahal and the Great Pyramid, both tombs to house their masters in death, or think of the Palace of Versailles and Las Vegas- both bold statements of celebrating living. We may not build pyramids of stone anymore, but Real Estate is still one of the most important possessions any of us aspires for. One’s own home is at once a necessity, and at once a realization of one’s ambition. For a business an office and/or a factory are central to its existence.
From the earliest days of computerization, there were attempts to digitize one or more aspects of the real estate industry’s lifecycle. In the late 1980s architecture and engineering adopted the first widespread computer aided design methods, but planning, marketing and publicity continued to use photographs or artists’ illustrations and at best, cardboard miniature models for visualization of complete structures. However, it wouldn’t be till the 2000s that realistic 3D modelling would start to offer an alternative. Today, powerful computers and equally powerful software programs exist to create and visualize real estate spaces with a very high degree of realism. See Figure 1 below to notice the progression in realism of not just the architectural elements, but of the trees, sky, shadows, and by 2019, realistic rendering of water in a pool.Figure 1: State of the art residential 3D renders by year (clockwise, from top left): 2002, 2008, 2015, 2019

Benefits of Real Estate CGI
Photographs can only capture what is real. Post processing can add elements here and there, but the basics do not change. 3D rendering changes that. Entire properties can be visualized, or unfinished rooms can be shown as if already real to use. Especially with photorealistic renders, the marketing aspect of real estate sales is benefited immensely. One might say that if a picture is worth a thousand words, then a 3D photorealistic render of a future-ready property is the picture that can replace the thousand words of convincing that a pre-seller might need to use to convince a potential buyer! Also obviously a 3D render can be used to market the property a lot further away than the immediate neighborhood. As we become more “online” in our lives, the day is not far when houses, especially the ones in demand will be sold purely through online inspection.
A second benefit of a photorealistic render is the degree of detail that can be created. As a result, a potential buyer can go into finer detail, such as the material used for the kitchen top, the flooring, the size of the windows, etc. and can hold the seller accountable if the finished property does not match the render (assuming exact recreation was promised in the first place). On the seller side, the 3D render can showcase any lighting, any season and can therefore be setup to showcase the property at its best. Maybe the trees in that neighbourhood have spectacular fall colors, but it is already winter. No problem! Time is not a constraint with 3D renders.
The last benefit is about emotions. Nothing beats actually seeing one’s future home. If the potential buyer can see themselves living, growing, entertaining, and thriving in that home, the pull of the home is irresistible. A prospective parent starts imagining their children growing up in that house, walking down the street, climbing that tree in the backyard, and so on. Once the emotional appeal is strong, the sale is halfway done! With a visualized house also comes a possibility of being able to ask a bigger price than a potential buyer might have been willing to pay, but if the seller is willing to commit that the house will be like the one visualized, a premium might be coming their way!
Types of 3D CGI for Real Estate
Real Estate CGI falls into five main categories. These are:
The future of CGI in Real Estate
The role of CGi is set to only increase. As devices get cheaper and more powerful and faster internet standards like 5G become available, the desire to make and view evermore realistic renders will only increase. We see CGI soon either replacing photographs in some cases or at least being accepted as an important part of the home buying/selling process. New emerging technologies like VR and AR promise to push the limits of reality and immersive experience once again. As those technologies go online, real estate- or rather CGI in real estate will follow close behind.
