How often do you build a new layout?

[RobertInOntario]

I used to be a serial rebuilder ...
All this is a long winded way of saying that I'm quite happy with the layout I have and don't plan on building another one for a long time.

Yes, I'm sure you can go overboard with the rebuilding / building.

This was partly the problem with my first layout -- I had re-laid track and reworked so many sections of it that this was causing problems. For example, I had to remove (dig out) old, previously-ballasted areas and remove cork, etc. It began to look messy as well as causing operating problems.

I think it's to each his own, but there is a limit to how many layouts you can have -- in terms of space to keep, costs and (as mentioned above) you can have problems if you re-work one too many times.
