Looks good for a first build.
I have some suggestions however:
- For the window you should use two 1x4 Bricks, and a 1x4 plate. This would make the window look nicer, and be easier to see out of. If the wall is two bricks thick this could also create an indent, which can look good, and be used for a windowsill, on the inside or outside
- Perhaps try and put some furniture in, or add stuff to the outside, which seems to be a bit empty.
Also, a simple way to make a door with events is to put in this:
onActivate | self | disappear[4]
In which the |'s separate boxes, and the box after disappear is a time in seconds
If you need/want it, I can PM you a screenshot of how it should look
Anyway, good job.
