Whilst at a Pound/Dollar store I saw these garden solar power lights, for 1.00 Pound/Dollar each.
Then I had an Instructable thought.
Step 1: Tools & Materials required.
Hot glue gun.
Rocket Glue / Super glue.
Model building, available from Model stores.
Solar garden LED light.
Assorted plastic strips, available from Model stores.
Step 2: Take the Lamp apart.
Step 3: Cut out the roof.
Then glue into place, along with the windows.
