Start with an architecture program trial

Some of the commercial architectural design programs are expensive, so explore your options first by using a free trial version.

I recommend: The free version of Plan 3D includes four modes: blueprint, 3D, overhead and elevation, and the option of alternating between them. You can design single- and multi-story buildings, add in light and shadow, and then take a virtual tour of your design, complete with animated windows and doors.

Find an architecture design program that offers support

No matter how design-savvy you are, or how easy-to-use your program is, you may still run into technical difficulties. Choose a program with included technical support, so your design plans are never stalled by technical problems.

I recommend: SmartDraw features free, 24-hour tech support and on online knowledge base. FloorPlanner is another good choice for support. It includes a blog, forums, an interactive manual you can turn to for assistance.

Choose architectural software that takes you beyond design

Some commercial architectural design programs incorporate not only design, but also project management, allowing you to track costs, manage human resources and equipment, and share information with colleagues off-site.

I recommend: A more advanced program is Chief Architect, a commercial architecture software program that includes cost estimating with materials list, a residential code checklist and the Chief Architect Viewer, which allows you to email your design to your clients in 3D.

Check out reviews of home design software

To make the most informed choice about architecture software programs, see what other people have to say by searching the Internet for home architecture software reviews. These reviews, written by fellow remodeling or architecture enthusiasts, usually cover the cost, ease of use and comparisons with other well-known software.

I recommend: You can find reviews of architecture software programs posted at ConsumerSearch and CNET.com.
