Rick - more information needed. So you can't build a shop on your property. That's all we know so far. Is a nice shed for garden tools allowed?
Or can you park a utility trailer or RV? Are temporary garden structures like pergolas or gazebos allowed? How about an arbor for vines? Can you add a small concrete patio adjacent to the home? Can you erect a temporary or permanent lean to or shed to the side of the house?
What do you want to build in your shop? The requirements for a model builder are vastly different from those for furniture construction or building race cars.
Are you physically able to move your power tools and tool boxes from a temporary storage location (at your home) to a suitable work area? Are you willing to work that way?
I've had home workshops of one type or another for building both little and big stuff through 68 years of my life. Most of the time they required more or less creativity to fit everything into less than perfect space. I should write a book on the subject to sit alongside all the "dream" workshop books that have been written. But at age 78 I don't have enough time for finishing most of my projects let alone writing books. So give us some more hints about your situation so we don't have to write a book nobody will read.
