Home studio or artistsā€™ cooperative?

Would moving enhance your career? Probably not.

My former studio.

My first professional studio space was a corner of our kitchen. The light was good and it had a laminate floor. A few years later, we enclosed our garage, adding full-spectrum fluorescent light bulbs and cat5 wiring.

Then we moved. I rented a space on the top floor of the Hungerford Building in Rochester. It was a large room facing east with beautiful light. Eventually I relocated my studio to the third floor of our house. This was a quirky, beautiful space with great light and lousy headroom. After a few years of bumping my head, I reshuffled my workspace in the former master bedroom at the head of the stairs. That studio was 325 square feet, large enough to teach six students. Here in Maine, I have a large, light room thatā€™s about a third of the total square footage of my house.
My current studio.
A dedicated home studio seems less expensive, but that is an illusion. The median list price per square foot in the United States is $140, according to Zillow. Special-purpose industrial space averages $11.25 a square foot/year. My last studioā€™s only upgrade was a better lighting system, but that still cost me thousands of dollars.
It is only cheaper to work from home if you already have space to burn. For my friends in New York City, where space is at a premium, a rented studio is often a better option.
Will your projected art income can really cover an additional rent payment? A home studio is already wrapped into your current rent or mortgage. Renting a studio is cheaper than adding on, but the cheapest solution is to repurpose an underutilized space youā€™re already paying for.
A professional studio needs good light (natural and enhanced), adequate storage, room to work, a space for office work, wi-fi, and separation from other people and activity. If youā€™re teaching, you also need to consider access to a restroom, handicapped accessibility, and safety.
Storage is something we often fail to consider when calculating our space needs.
Art materials should be kept away from food prep areas. Thatā€™s especially true of pastels, which allow pigment to be airborne. Having said that, risks associated with oil paints are overstated. Still, the pigments in art suppliesā€”and some solventsā€”arenā€™t good to ingest. I ran a whole-house air cleaner in my first house.
I need an orderly environment. Itā€™s difficult for me to pick up my brushes when there are dishes in the sink. I donā€™t like visitors to my studio. It was that need for order that drove me to a rented studio when my kids were little. However, I found myself leaving work every afternoon at 3:30 when my youngest child got home from school. I had more flexibility than my husband, who worked from an office. 
Is the neighborhood in which your cooperative studio is located really safe? In Rochester, my studio was on the fringes of a tough neighborhood. I could work late at night in my locked studio; the parking lot and corridors were the problem.
325 square feet was sufficient to teach six students.
How introverted are you? Some artists are challenged and motivated by other artists nearby. Others find community to be a distraction. However, the network you build in an artistā€™s cooperative can be invaluable; so too can their cooperative art shows.
Will an outside studio enhance your career? Unless youā€™re in a prestigious cooperative, no. Neither gallerists nor potential clients judge you by your address; they care about your work.

Working from home: the pros and cons

My last studio was neater than my current one. I wonder why.
Iā€™ve had studios in my home and in a commercial space. Neither is inherently better. Itā€™s just a question of what works best for you. 
Sometimes the decision requires no thought. If thereā€™s no room in your house, a rented studio space is probably cheaper than moving. I started painting professionally in a corner of my kitchen. In some ways that was the most pleasant workspace I ever had, since it was light and bright and I could easily keep an eye on the kids. But it didnā€™t take long to outgrow.
The Hungerford Building in Rochester is a mixed-use building that is home to more than a hundred working artists. I had a studio there long before it had a First Friday event, but it was still open to the public. My workspace was large, with high ceilings, ample north-facing windows and good parking. I met many fine artists there. There were, of course, all the usual amenities.
On the other hand, some residents were careless with the security codes. That meant that the building was never truly secure. It was in a marginal neighborhood. I soon realized that it wasnā€™t safe after dark.  At the time, working at night was a necessity. I had young children who shortened my daylight work options considerably.
There was also the question of access. I was doing art festivals and fairs. My studio was on the fourth floor. This was accessible by freight elevator, but there was still a lot of trundling before I got my work, my booth and my tent down to the commercial loading dock. That freight elevator was the only option for visitors, too. It was cumbersome and hard to use.
There was also the rent, which added about $6000 a year to my fixed costs.
One of the downsides of a home studio is that you will end up storing paintings everywhere. This is the bedroom in our former home.
We bought our current house for the studio. This is my fourth home-based workspace. My husband works from home too, so in some ways you could describe this house as a large atelier with attached living quarters. Itā€™s on Route 1, which is Maineā€™s commercial drag, and it has a small parking lot.
Owning my workspace is a financial advantage in the same way as home ownership. It also gives me greater flexibility in how I use the space. I can work whenever I want. Thereā€™s a nice kitchen. Thereā€™s a backup server and a good computer network. I can bring the elderly Jack Russell terrier to work with me. And of course, thereā€™s no commute.
There is, of course, a downside: distraction.
ā€œAfter each big painting I usually clean my studio before starting another painting. I got as far as dumping the dirty water,ā€ Christine Waara wrote yesterday. ā€œWhile dumping water in the laundry room I started doing laundry. While gathering laundry, I came across some letters I’ve been meaning to answer. Went to find some note cards to answer the letters and saw that the dehumidifier was full. Dumped the dehumidifier andā€¦ squirrel!ā€
Your kids will wander in and out of your home-based workspace. That’s usually a good thing.
I have a few tricks to manage my transition from hausfrau to artist. I leave my next piece on my easel, to remember where Iā€™m going and what I was thinking about. I work regular hours whenever I can. Human beings are programmed for routine. Our brains settle down faster when we use them the same way at the same time every day.
Home-based workers end up being the gophers for our families, because our schedules are flexible. People stop by because they think weā€™re ā€˜free.ā€™ But, overall, I think there is less of this than in a communal workspace, which sometimes suffer from excessive conviviality. And I never have meetings. The dog canā€™t talk.
