Space Planning and Furniture Selection

It might go without saying, but choosing the proper materials is perhaps the most important thing I do. Finding the right textures, patterns, colors, and trims will go a long way in establishing the identity of your space.
After we’ve established your look, it’ll be time to place your new and old items and fill your space. Tying each element together is what creates a cohesive look, and it can’t be accomplished without proper planning. Before the work begins, I’ll offer you a few drawings to show you the possibilities. When you need help finding the right furniture to fit your space, I’ll be right there by your side.

Interested in Green Interior Design?

I certainly hope so. As a green interior design expert, I can help you select the proper appliances, heating and cooling units, and other energy-saving elements to make sure you’re leaving as light a carbon footprint as possible. And don’t worry, to me, the look of these items and how they tie into your scheme are just as important as their efficiency.

"Our new lower level is both beautiful and functional thanks to MJM Design Company. It was great working with Joyce Mathis. She somehow figured out what design style we would like and created three new rooms that we now love. Her help in selecting furnishings, colors, finishes, and the subtle extras that made the area into a unified design was great.
Not content to help us select something we thought was OK, she always persevered until she found something we thought was perfect. The end result is a lot of function in relatively small space that feels spacious and looks beautiful. It's now our favorite space."
