Well, that was quick!

 We have a ground floor frame already. They poured the slab last Saturday and started the frame on Wednesday. Currently it is pouring with rain and there were still four or five guys working on it this morning! We are starting to get a feel for the room sizes. Our first impression is that there are a lot of windows and they're huge! The corridor does look very narrow, but we knew it would be. Apparently the garage is an infill slab and poured later.
