My dogs are in outdoor kennels when I'm out but if I only had one dog it would be in most of the time (out only if I knew I had to go out for hours).
I wouldn't bother having a dog if it had to be outside - what's the point in having a dog if you don't want it with you? It just isn't fair to have a social animal like a dog isolated all day. If you are considering having a dog kennelled, you have to have at least 2!
You're right, an older dog not used to kennels probably would bark all the time. depending on the breed, the dog might well bark even if it was used to living in a kennel. Many dogs bark out of sheer boredom.
Putting a pup in a kennel would probably mean you'd have great problems housetraining as it would be reluctant to soil its kennel or run, but wouldn't consider the house as its property!

How much would it cost? How long is a piece of string? Wood isn't cheap & good quality wood is definately not cheap, you may find it's cheaper to buy if you can get a good 2nd hand kennel. Then there's the run, doing it properly with galavanised weldmesh costs an arm & a leg.
