One of the biggest challenges a developer faces is selling properties that are still under construction. While off-plan property sales offer buyers several benefits, like first pick of prime units, flexible payment plans, and, most importantly, lower entry prices. However, since investing in a property is a big commitment, most buyers don't purchase a property unless they are convinced it is worth their life's savings. Just handing out brochures, listing out, or relying on the reputation or ratings of their past projects doesn't always help developers gain a buyer's confidence. This is why real estate developers are starting to use 3D architectural walkthroughs to sell unbuilt properties.

What is a 3D Architectural Walkthrough in Real Estate?

A 3D architectural walkthrough is a digital recreation of the propertythat the sales teams can use to give buyers virtual 360-degree tours. The reason developers use this is that, instead of relying on basic renders, they can let buyers explore the entire space in real time in a way that is similar to them taking an in-person tour of a physical show flat.

Thus, a buyer can walk between the different rooms, check out the interior finishes, explore the layout using interactive floor plans, easily switch between interior and exterior spaces, and more. This is also what separates these architectural walkthroughs from video tours. There is no singular defined path that a camera has to follow, and the exploration experience is unique for all the buyers.

Why Developers Should Use 3D Architectural Walkthroughs?

Helps Faster Decision Making by Improving Visualization

The biggest hurdle a buyer faces when deciding whether or not to purchase a property is clarity. Since real estate is a costly investment, they need to be absolutely sure about liking the flat and whether it justifies the money they are spending. With 3D architectural walkthroughs, it becomes easier for the sales team to help buyers visualize their future home. They can give them 360-degree virtual tours, which allow them to explore a property in its entirety. With interactive floor plans and dollhouse views, it becomes easier for the buyers to understand a property's layout. The ArchViz software can even showcase to buyers their neighborhood to show how accessible everyday necessities like groceries, convenience stores, hospitals, metro or railway stations, and more are. All of this helps buyers make informed decisions faster.

Reduces Reliance on Physical Show Flats

One of the most essential tools for real estate marketing is physical show flats. However, having them quickly set up isn't really possible, especially when the project is still in its early stages of development. But with 3D architectural walkthroughs, the reliance on physical show flats is significantly less, as the sales teams can simply make use of virtual show flats. Thus, they get to virtually explore the property as if they were doing it physically. Thanks to additional features like window view simulation, buyers can check out what the view outside their window looks like during different times of the day and weather conditions. The developer can even include customization features to let buyers emotionally connect with their future home by letting them make simple changes like playing with the layout, changing the home's wallpaper, adding or removing furniture, and more. All of these features give a level of tangibility that is often not even possible with physical show flats.

Gives Developer Buyer Behavior Data

Another important use of 3D architectural walkthroughs is that such software is capable of collecting and analyzing user data. Thus, a developer gets to learn exactly how a buyer interacts with their software and, in turn, their future property. This typically includes data on how long the buyers interacted with their software, the different touchpoints they interacted with, how long they interacted with each touchpoint, the features they ignored, and more. This helps buyers improve their existing software and can even use the information to make changes in their future projects for the better.

How Our Client Used 3D Architectural Walkthrough for Pre-Sales

Hiranandani Belicia

Hiranandani Belicia offers its residents a 48-storey high-rise tower that features dual views of the Yeoor Hills and the city-facing skyline. The project is built on a 1.5-acre land parcel and has over 15 amenities to improve its residents' quality of life. However, despite having these many features to offer, since the project is still under construction, they needed something more tangible to boost their pre-sales. This is why they teamed up with V-Estate to offer 3D architectural walkthroughs that showcase all of these features to the buyer in an interactive manner while helping them visualize their future home better. 

The solution we offered was 3 dedicated zones, two of which focused on showcasing the property's architecture, amenities, and landscape. The third zone contained an interactive sales pod where the buyers could have private discussions with the sales team. Here is how each zone worked: 

  • Zone 1 - Architectural 3D Visualization: Here, the buyers could check out Hiranandani Belicia's Neo-Classical architecture. They could see detailed renders of its structures like pediments, pilasters, cornices, jalis, grooves, nibs, grooving panels, and railings.
  • Zone 2 - Landscape & Amenities Experience: This zone showcased different amenities like Yoga Deck, Games Room, Mini Party Hall, Squash Court, and more. Buyers could also check out the Yeoor Hills and city-facing skyline views.
  • Zone 3 - Interactive Sales Pod: Finally, the buyers could have private discussions with the sales teams regarding any doubts they might have regarding the property. This zone allows them to use Spaci, the 3D architectural walkthrough software, to explore a dollhouse view of interiors, panoramic window views with day/night simulation, 360 views of exteriors, and more.

The 3D architectural walkthrough proved useful and resulted in:

  • 30% increase in conversion in sales. The industry average is 5% - 10%.
  • The sales team started using the 3D architectural walkthrough software extensively, as it helped resolve client concerns faster.

In conclusion, 3D architectural walkthroughs are digital replicas of the property that a developer is working on. These can be made before or as soon as the construction begins. They exist to help improve visualization of the property for buyers by allowing them to check their future home's exteriors, interiors, amenities, and other features. 3D architectural walkthroughs are especially useful to the sales teams as they open up more possibilities for pre-sales and remote sales. They even help developers get insight into how the user interacts with their property through the 3D architectural walkthrough software by analyzing their behavior data.
