Shannon, Try and find Kodak books K-13 "Photolab Design for professionals", KW-14 "Building a home Darkroom", and "Making Darkrooms Saferooms" by the National Press Photographers Association. "Building the home Darkroom" is a very informative book. It will fill you with ideas and can give you a concept of the work involved. I am not a fan of concrete floors especially in cold damp climates. My dark room project really started from scratch, no water, electricity or building. Years later of working in my spare time it is done. It ended in a 10 by 24 foot space with a total sink space of 17 by 3 foot, and drying cabinets for prints and film on the wet side. The dry side has 3 large cabinets with counter tops, a long commercial drafting table, 2 enlargers mounted on one of the cabinets, and a Durst floor standing enlarger. The 2 large cabinets with leveling feet have metal roll out drafting room storage drawers plus larger storage drawers on heavy sliders. The third smaller cabinet with roll out drawer stores enlarger condensers, film carriers, lens mounts, etc for the Durst enlarger. I built all the sink bases, cabinets, sheet rock the ceiling, laid a sub floor covered with fitted sheet of Congolium flooring overlaid with interlocking anti fatigue mats. I built a quasi laminar flow exhaust system in a plenum chamber that runs along the sink area including the print drying cabinet with it's intake at sink level. The multi-speed 200 to 1500 c.f.m. exhaust fans are internally mounted in an exhaust stack projecting from the roof with closing metal louvers. The plenum also houses all the electrical for the wet side, Lights, clocks, tray heaters, dry mount press, and microwave, etc. On the surface of the plenum are multiple water temperature control valves with distribution manifolds for the Jobo processor, film, and print washers, hand washing, etc. Under the sinks are master water shut off valves, the inlet manifold with hot and cold water 5 micro filters with pressure regulators and gauges. This space is also used for tray storage, nitrogen system, air compressor, fixer silver reclaiming system, water circulation heater, etc. Although I rarely make prints larger than 11x16 the print drying cabinet is large enough to dry 30x40 prints and has space for the dry mount press and microwave on its counter top. The film drying cabinet has filtered force air heat and is large enough to hang 15 120films. The dry side has a ceiling soffet running its length. The air inlet is thru a slot at the juncture of the soffet, and the wall. The air enters through the roof from a closing louvered inlet with removable filters. I decided against a room that would maintain a positive pressure ventilation system because this could lead to contamination of the living area. The Soffet also contains electrical distribution, and adjustable intensity florescent-incandescent lighting system providing 50 to 200 foot candle level on the counter tops. The main power inlet enter on one end of the room into a master GFI then into a master switch, with two sub switches for the wet and dry side. The wet side has 16 outlets, and the dry side has 32 outlets. The dry side electrical outlets has been doubled from the original installation due to addition of enlargers, clocks, power relays, cooling fans, analyzers, densitometers, electrostatic film cleaners, work lights, etc. The dry side wall also has shelves for paper storage etc. The large drafting table gives me a work area for print finishing and mounting. Would I do it this way again is a good question? I bought a photo studio and lab from an estate and needed some place to put it all. Do I need all this to make photos NO, do I like designing Yes, do I like building NO. Is it a great lab to work in, YES. My only regret it is not portable, if I ever do it again I will down size and build it in an Air Stream trailer. P.S. I live in the wilderness and this is run off generators, inverters, and a bank of batteries with no solar because I live under the redwood trees. The water is collected from a mountain spring, pump 300 feet up a mountain into storage tanks then pumped to the building with a booster pump, and my wife thinks I'm crazy, but I reality this is what I had to do to live with her because in her words "I'm not moving".

It will be an outbuilding built from scratch. Any suggestions? I know you have to have a wet side and a dry side, and I am a stickler for perfect ventilation, and I want to have a concrete floor. Other than that I am open to suggestions. --shannon ============================================================================ ================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
