Here are some photos of the completed structure. These are today, now that the construction materials are cleared away. At 10:30 am outside was 2C and the inside was 23C. My interior designer (wife) bought a roll of large bubble wrap and has installed it inside away from the polycarbonate but covering the entire interior area. That is why the photos look opaque.
