I believe that having a proper workspace can be a real luxury. I'm very lucky that my studio/office is a sizable room that allows me the space to do what I need to do. It's one of the reasons that we bought this house nearly 30 years ago.
My wife is in the process of reclaiming another room to be her sewing/project room. It's been a struggle for a variety of reasons and I feel bad that it's not working the way she wants it to (so far). But I do understand her need. It's the same need that all artists have. Just trying to find the right spot to not only be able to do the physical work, but derive inspiration also.
A good friend converted a one-car garage into a recording studio. He records, practices, teaches and jams in that space. Of all of the people that go to his studio each week, I'm one of the few that actually has been inside the house. He is able to keep personal and professional life separate.
An artist I know recently purchased a new house. Before she moved in she spent time and money converting one room into her paint studio.
Another artist actually built another house with a 3 car garage on her property so that she could paint, frame, and make her own prints. It would be easy to point and say that success has its advantages, but success also comes with its problems. The house was the only way she could solve her space problems and expand her business.
I watched a show on TV recently and a real estate agent was showing a listing to a famous country music artist. It was a beautiful home set in the mountains and had a stunning view. As he stood and looked out of the window he commented that this would be his practice room. The real estate agent said in a very condescending voice, "Oh no Dear. This will be your dining room. There's plenty of room for you to practice in the basement." He quickly and sternly replied, "I will practice anywhere I want. Where I am motivated and inspired. The music is the only way I could afford this beautiful home."
I have a friend who is a talented pianist. He lives in an apartment and drives to the university to use one of their practice rooms. These rooms are usually bare and not sound proof so you can hear everyone else practice too. Only in his mid-thirties and with a successful career underway he was talking about quitting and finding another career. "I'm getting tired of spending my days alone in a practice room", he confided. I understand. I wouldn't want to spend several hours every day in one of those rooms either.
I realize that in many ways this is a "first-world" problem. But we live our lives the best way we can. My professional goal in life has always been to decorate other lives with music. For me to do my work effectively I need to be in the proper space. Yes I can work nearly anywhere, but only in short bursts, not for nearly a half century. I feel bad that I don't know how to help my wife in her quest because I realize how important having the proper space is. I can't speak for others, but in this house space truly is the final frontier.
