We went on site weekly, and drove past the house daily, because we lived only a few streets away at the time and our sons (especially the 6 year old) were just so excited about the build so they loved seeing the progress. All of this done without permission though I must admit. On one occasion my husband raised an issue with our SS and he was like "well you wouldn't know that if you hadn't been on site without permission" which is of course true, but husband just said "doesn't matter now because I do know about it, so what is going to be done".
