To constructively protect your build, you need a trade person who appreciates this type of work. Luckily those crafts people do exist and their numbers are rising.
2) Be aware of water transportation by dry rot: There is only one, very rare exemption which can infest even very dry wood.

At a later point a vapor retardant might get injured and cause damage. The best solution is a solid, homogenous wooden wall like the Holz100 system presents. Here the vapor pressure is continuously slowed down instead of suppressed by a single, vulnerable layer of foil and guarantees 100% protection from condensation moisture and fungus.
Condensation and dew water still remain risky for wood frame walls.
It is important to ask professional tradesmen about all types of insulation. Ask them to calculate the dew point for every ceiling and wall construction and to confirm their results in writing. Condensation, Frost and Foils:
To build a more energy efficient home, more and better thermal insulation is in demand. However proper insulation needs to dam and should not seal. Avoid water and air tight foils (vapor barriers) and rather use a recommended vapor retardant instead of a barrier. For an external cladding, the vertical facade is preferable to horizontal. Water can run off all the wooden components which are exposed to rain and dampness and doesn't pool.
Weather boards are to be installed onto a slatted frame allowing free air movement and circulation to wooden building components. Keep wood off the moist earth. Cladding and posts should never end up in the ground or soil. Make sure you build on sufficient foundation made from brick, concrete or rock.
