There are just 2 simple rules at the planning stage, which will help you very much
1)Decide when you are going to live in your home
If it's a summer home, then you won't have to care about warm and you wouldn't need to use insulating materials. This will save your time and money.
If the house is decided to be used in winter (if you have real cold winters in your region), then you should be ready to a rising price of the house. Don't forget to ask the producer whether warm insulation work is included in price, or not.
If you haven't chosen the using period of your wooden home, but you have enough money to make the isolation, better do it not to have problems with te keeping warm in the future.
2) Make the plan of your future house
Ask architect working in the company which you want to build your house.Yes, you should pay him for this work, but he or she'll definitly create the plan of your house considering your weshes and wood features. Professionals could help you to racionalisethe space and to remove useless: excess and unused area.
That could also save you time and money.
If you have a friend-architect, it's perfect. But please, don't follow his each word. He could say that without this column area looks much better, but I'll say it again "professionals will concider wood characteristics".
This advice must help you, but never forget that everything depends on a company with which you are working. It shoud be reliable and conscientious.
