Thanks for All the suggestions and ideas.
Looks like the plan is shaping up nicely. We are going to possibly plant some durian trees and create a mini plantation in the extra land that is apparently very well drained and likely a good soil type.
Nana Thailand is going to take some soil samples to the city to get tested to confirm soil will work for durian, if not we will plant something else.
When I was younger, I used to stay on a durian farm in pattani (before all the troubles). Used to hate picking the durians off the ground. They are very tall trees and the durians would be imbedded in the soil.
