When it comes to 3D architecture and interior design, the thing that takes the most time is creating the models themselves. Granted, in a lot of situations, they need to be done from scratch but not for everything.

This is why we decided to dig around the web in an attempt to find alternative solutions, and we like to think that we’ve succeeded.

We’re sure you’d be interested in hearing about various free libraries of 3D models available online. These databases are usually well categorized, and you can find anything from models of boats, cars, trees to furniture, sinks, people, and more.

This can be an indispensable time-saver for designers trying to create an attractive and lively architectural design for investors and other parties of interest.

There are all kinds of models to be found on these websites. So, you might want to be careful with how much time you spend searching for the “perfect model” - just browsing can take away hours.
