This looks interesting.  Living Room from Helix Coding is an Interior Design app designed specifically for the iPad. It has a nice looking interface and some useful features.  

Here is the app description from the site:

LivingRoom for iPad gives you the tools to plan and design your space — from the floor plan to laying out furniture to choosing materials. Pick from a large library of objects to place in your rooms, keep notes for each project, even add custom textures from your photo library! LivingRoom for iPad lets you see, touch, and share your design ideas.

With key features like auto-save, a good range of objects in the built-in library, customisable textures for all objects in your design, the ability to save the design to your Photo Library or email it to someone as a PDF and integrated Notes for each project, it looks like a great little app for running up room layouts or designs on the move.

The developers seem quite responsive to user requests too with the app having recently been updated to version 1.1 to incorporate a lot of requested improvements.

Living Room is available in the App Store for £2.99 ($4.99).  Check out the demo video below for more of an idea of what the app can do, and if you try it out, as always, let us know what you think in the comments below.
