deck-houses were traditionally built from
solid planks of wood.
This is an excellent method particularly if you want a bright natural
However, it does have its drawbacks.

Another method which has successfully been used to build trunk sides is

Just remember that if you spend a lot of time and effort building that
cabin you want it to last, so use Marine grade ply and seal the edges
especially around any openings such as portlights.
The thickness of the ply you can use will depend on the amount of

Trying to bend plywood thicker than ½ inch over a short distance will

The next problem is how to
join the corners.
It is possible to make a 'box' with
simple butted corners but this wont be very strong, any exposed end
will be prone to rot and it will look cheap.
The preferred method is

rabbeted corner post.
