Many furniture retailers have room planners on their website and they are free. I believe the planners are usually made by Icovia.
You can move walls, appliances, furniture and re-size anything as needed. You normally have to give an email to use them.
If a site doesn't list room planner, look under design tools.

HTH!

Autodesk HomeStyler is a free, on-line program and pottery barn also lets you lgin and create rooms with their furniture, etc.

I just tried the autodesk & it is easy to use but I couldn't do quite as much as I would like to with it. Although there are still a lot of things on the site I need to check out. I will try & find furniture retailer sites & see what happens. Thanks, Terri

I have the Better Homes and Gardens one and found it relatively easy to use, once I got over the initial learning curve. Though occasionally I still end up with grass growing in my living room and struggle to figure out how to remove it. I haven't used any other software, so I have no idea how it compares. The BHG software also came with a phonebook-sized instruction manual, but I just played around with it until I figured it out.

It is limited in what it can do. It works best for the kitchen/bath and playing around with layouts than for furniture and colors. Also, if you have a home filled with unique features, as do I, you have to be creative in how you manipulate the software to simulate the (usually limiting) features that we are trying to decorate around. For example, I have four (no, that's not a typo) rounded, corner, floor to ceiling stone fireplaces. (Yes, insane, I know.) With the software, I have to make a diagonal stone wall in the corner, insert a fireplace in the wall, and imagine it rounded.

That said, getting past the learning curve on the software was well worth it for me. Pre-software, communicating the plans for our home projects was beginning to test our household's conflict resolution skills. I like being able to mock up what is in my head and 42 magazine clippings to show The Hubs instead of saying, "Remember the taupe sofa with the fringe I showed you last week in the magazine at the dentist office? Anyway, remember the kitchen in the background? I've decided that's what I want our kitchen to look like. Do you think that would look good?"

"Wha..?"

I guess I need to just spend some more time with the program & figure it out...I was mostly wanting to change wall, flooring & cabinets in a bath & kitchen. At least that is all I want to do for now, could change tomorrow. Better bite the bullet & just learn it. LOL Thanks, Terri
