kingdragonfly: The lure of riches brings out some dubious sellers.
I've previously noticed several houses sold "sight unseen", being dumped by the bank, where no one was allowed to enter the house, not even the real estate agent.
This Trademe ad has only this text: "Flat Corner Section for sale in Bell Block. This is a good opportunity to build your dream home in prime location. Call or email me today."
I put the address into the New Plymouth proposed district plan
Most of the property was an archaeological site, and classified as a Māori site of cultural significance.
When I emailed the owner, here's his complete response:
"Hi
Thank you for your inquiry.
For this matter, please contact NPDC directly.
Kind regards"
That seems a reasonable response.
There's no reason why you shouldn't build on the site given in your post. Half of London sits atop a huge variety of interesting archeology. It gets recorded then covered over and built on. Same in most European countries.
No doubt NPDC would provide the required advice.
