Congratulations on your new property. We too, just purcahsed a new 4 hectare farm a few miles from the coast and up 300 ft. But those occasional typhoon storms still bring in up to 70mph winds and heavy rains. Both cause flooding and trees down, rip off roofs. So I am building our house and greenhouses partially underground and still berming it up using geodesic dome shapes for structural integrity. The shape naturally pushes wind over and around it and could save some of my trees in the redirection. There are plenty of CAD files for tunnels, round geodesic domes, along with more traditional rectangle buildings with arches instead of hard corner edges. These buildings can handle branches or trees, or loads, or 200 mph winds according to the US architecture association. It also can be among the cheapest and efficient ways to build... in a short time.
Just a thought...
