Good question! I'm afraid I'll need more info in order to answer your question. There are so many variables involved here. Do you have a set of plans? What kind of total square footage are we talking? What are the specs of each unit? Is the work space finished or unfinished? What types of finishes in the living space (basic, mid, or luxury)? What is the overall style (traditional, modern, etc.)? What part of town? This is obviously a question that can't be answered in a post. Please feel free to contact me to discuss further. Thanks.
