Here are the steps and the costs that I went through in order to get my studio.

To start, I dug out an area about 120sqft. (10' x 8') for me to level it out, and place a floor for the 10' x 8' shed. I decided to use a flat square shovel, and dig lines in the grass, so that I could then go about 2" under the grass, and essentially create "sod". Good to use for in small areas in another part of the lawn ;)

There are sooo many locations that you can place your studio. I've seen extra bedrooms, garages, basements, sheds, barns, etc all turned into a personal studio space. I went with the shed choice. The house I'm living in is over 100yrs old, and I didn't want to risk it burning down ;)
If you choose to convert a part of your home into a glass studio, please ensure that you ensure you have met all the safety measures. Fire proof backing behind the torch, ceramic or fire resitant flooring, and most importantly - ventilation. I have safety sections on my site that go into this further.
I was able to find a metal shed from Kent for $483 with tax. It's 10' x 8'. I chose an area in my yard, close to the house to help with wind conditions, but far enough away not to be a fire hazard.

After the gravel, I added approximately a 2" layer of sand. This was the most important leveling layer. This helps with further drainage, plus should help keep other plants and weeds from growing up through your floor;) This is the last layer before I laid down the patio stones.
The patio stones I used are 24" x 24" concrete slabs. I was able to get them on sale for only $9.69/ea from Home Hardware. With taxes and delivery, my total was $240.12.
I started in the upper left corner,then filled the space in, leveling as I went. I kept going from side to side, then to the middle. Almost diagonally. Now I wasn't able to make this a permanent structure, so I didn't seal the gap between the slabs with concrete, I just filled any gaps with sand.

Once I did the rough dig, I went back to level it. The ground was fairly firm, so I was able to loosen it to move some soil around, then stomp on it. If you have access to a roller, it would probably make it easier for you. After I had this level, I did a small layer of gravel for extra stability and drainage. I have a large property, so I was able to just use my own gravel and sand. I don't believe it's too pricey if you need to order some however.

I had recently injured my foot, so there was a delay in the construction process. Luckily my boyfriend helped me build the shed, and even though I had an injured foot, the two of us were able to do it in small steps.

Duramax, the shed company, says that it should take about 4 hours or so depending on the comfort level of the people building it. It took us a couple hours each day for about three days. I live on the coast, so winds and rain stopped us from completing it all in one day.

The shed pieces were well labeled. The instructions could have been a bit clearer but with a bit of patience, we were able to get it done!
