We weren't sure how to make best use of a very strange shaped room in our house so a family member recommended that we call Roberta. She came out to see us and spent a couple of hours tossing around ideas and drawing out sketches while her husband took measurements. A week or so later we visited her office and she had taken the ideas a step further and sketched them out in more detail.
The whole experience actually felt more like a discussion between friends than a professional relationship (in a good way!). We've now got a really clear idea of what we're going to do in the room and can feel confident buying the furniture and making the changes we need to make.
Approximate cost: $220
