   be very very afraid...

   get a strategy up front for how you are going to handle the moisture..

   you can mitigate some of it if you can include a pool blanket caddy that willactually get used..

   ..i would go with mechanical dehumidification..

   and this is one place where i would insist on a positive vapor barrier directly behind the wall /ceiling surface..

   another often overlooked problem is insulating the pool itself..the equilibrium ground temp under the pool is 45-50 deg. depending on climate..

   that is one big heat loss if you are trying to maintain 70deg. pool water...

   consider water - to - air heat pump.....

   figure 70 deg. water.. 80 deg air... 50% RH..

   we used DOUBLE sliding glass doors as the main window wall.....

   good luck..

   *Don't overlook the corrosive impact of pool chemicals on every fastener and hardware item used for the project.Good luck, Steve

   *The engineers we use don't recommend using wood trusses over pools, but it's done all the time. I'd definitely go for some major attic ventilation.

   *Ron, why aren't trusses recommended over pools? Does it have to do with nail plate corrosion?Curiously, Steve

   Use cbs construction. (Concrete block and steel.) Your customer can afford it.

   Steve -

   Two reasons, I think. Corrosion of the connector plates is one thing. They're typically galvanized, but do not last indefinitely iin wet environments.

   Second, The truss plates can back out if there are enough severe increases and decreases in humidity.

   But - like I said - It's done all the time.

   There will not be any 2x truss plates in the construciton. The trusses will be timber with mortise and tenon joints. I have had some reponse from timber framing companies. Of course, they say it's no problem, but I'm still rather concerned, cosidering you're talking about a five to six hundred thousand dollar building.

   *To Gomer, the customer would fall over from a heartattack if we used anything that was as "modern" looking, their words, as conrete block and steel... Think cottage

   I am designing a pool house for a rather wealthy client. The structure will be about 28 feet by 64 feet. I am concerned about the effects of moisture on the structure. The house has a cottage feel to it, although it is about 8000 square feet. The only solution I can think of to retain the warm feel is a timber frame with wood veneered stress skin panels. Has anyone ever encountered this problem, or does anyone have any ideas. Thank you.

   don.. sounds like you've got the right budget..is some of that money available for a good mechanical engineer..especially the dehumidification..

   .. i saw joe lstiburek talk in providence at the jlc live.. he had some novel solutions to a pool building problem... you know some of the problems..

   HIGH humidity... low outdoor temps.. high indoor temps...big delta-T.... one giant condensing surface...and a lot of potential bozos who think they know what they are bidding on...

   use a bid list of qualified subs.. if they haven't done it before and don't know the problems... don't use 'em..

   b but hey, whadda i no ?
