3D plan creation: which architectural software should you choose?

The creation of 3D building plans is an invaluable asset in the real estate business. Indeed, even the most experienced salespeople know just how powerful a visualization of a future property can be in enhancing the value of a real estate project. It's an invaluable selling point for sales meetings.

However, it requires professional architectural software.

That's why we recommend that you equip yourself with the best 3D house plan software, or at least the one best suited to your ambitions.

To help you make the right decision, appvizer explains in this article the features you need to consider when choosing the tool that will contribute to the success of your real estate projects. And because we recognize that architecture-related professions require total concentration on their core business, we go one step further by presenting software that simplifies project management and administration.

Which professional architecture software should I choose?

Towards free 3D drawing software?

Interested in free software?

You'll find some on the market, like Kozikaza. However, even if they can help you out, beware! Free software for interior design and plan creation doesn't offer the same rendering quality as paid-for software.

Even a large-scale project, such as a luxury villa, can suffer from an unfortunate perspective, a disappointing design or modeling that does the project a disservice. This can have a detrimental effect on the closing of a sale.

What's more, free solutions often don't include interesting features such as 360° video virtual tours. And yet, this type of functionality is a profitable added value to the sale.

That's why we recommend that you turn to paid tools that are more in tune with the real needs of architects and real estate salespeople.

Among them, we have selected three:
