Electric outlets counter high. Or even on the ceiling. No bending to plug in something. Moveable work islands (our needs change). Lighting, never enough. You are new construction without windows...can you install sky lights or light tubes? Storage, storage, storage. Both stationary and mobile. A place for everything...and label the contents. Whole house vacuum system with access to your room, a dedicated hose stored in the room for cleaning. Hardwood floor, not carpet, easy clean up, no lost pins to be "found" by your feet. Gel mats at cutting table-or area where you will stand a long time. Small dorm fridge for refreshments, Kurig for coffee and tea. A bathroom would be nice, with access to a large wash basin to rinse water-soluble stabilizers and markers.
