Heya Rex and Simba!
Plans look fine by me and in line with the other projects you've done on Massey's Hook, which we are all very happy with. It only makes sense you beautify the remaining lands of the peninsula.
You surely already know, but you may find terra more challenging to do than on the past, hopefully this will be solved sooner than later once we get 1.20. Till then things may go slower. This applies to all the project, including the extension you asked for, whcih we approve in any case.
Having said all that, consider the redo appeal and the app approved! Good luck and have fun!
