Looks fantastic, never thought I'd say that about one of those concrete towers :D
I think "(something) House" and "(something) Tower" are also pretty common for towers like this (e.g. Apollo House in Peep Show, and the infamous Grenfell Tower).
Thinking of punny (but not Lego-related) names for the Point, here are some suggestions:
- Wossda Point
- Bessyda Point
- Vantage Point
Some Lego-related suggestions that would work with Point, House or Tower:
- Studley
- Mocwell
- Medstone (a reference to Lego's official name for the LBG - Medium Stone Grey)
And if you want it to sound more like home, how about some anglicised Irish? Some suggestions from experience while trying to come up with an anglicised Irish name for my own city (as yet undecided):
- Ardbreeca (ard bríce - high bricks)
- Togamoore (tógtha mór - built big)
- Partanalee (páirteanna liath - grey parts)
