The first photo is of the (likely lead) painted original flooring, and we simply cannot sand that down and use it, for obvious reasons.
The next photo is a view from the stairs, and while things might not look too bad up here there is still a bunch of work to do. For example, the door to the second bedroom no longer closes due to the bracing and raising of the floor that was required in order to ensure it would not come down. We also need proper safety mechanisms such as smoke detectors, railings, and windows that are the required size, in case of emergency evacuation. These things can all be done now, since we can now access this part of the house!
As always, our daughter (who we call ‘the inspector’) is as involved as a two year old can be, and she loves to ‘help’. The weather in January has made this somewhat difficult but we work with it the best we can.
