After four previous attempts to get it something like. All ripped off again and sanded down once more. And after a great deal of deep breathing;
here it is.
There are very few places from which this fourth wall can be viewed in situ when the bungalow is fully assembled. Windows and doorways will give passing sightings, perhaps.
This kitchen room box will be closed off by perspex to keep it clean(er) and allow the peek-a-boo sightings of the fourth wall when the bungalow group of boxes is assembled together.
Congratulations! It looks like you have been successful 🙂
Thanks – glad that’s more or less staying where it is ( ◡́.◡̀)(^◡^ )
