..Must have taken me an hour to find a lost 60mm in one corner of a basement....
Some elaboration is in order. When working with an old house, this was initially the biggest pitfall when outlining a SH3D plan. Walls, corners are rarely as perfect in real life as in the plan. When redecorating the basement, it dawned on me that the room was not a perfect rectangle. A closer inspection on the outside eventually revealed why. This was the point I missed. A foundation that was not perfectly aligned with the construction on top. Only goes to show the importance of good (initial) measurements. As you can see, new window (and fire escape), ventilation and frost-proof tap (with obligatory inspection hatch on inside wall) in place. Inside almost finished
ok
