I have 3 single, older, traditional wood-sided garage doors. I am making a room out of the garage and, fixing 2 doors, but still want 1 door to open. Each door is 8'Wx7'H with 5" horizontal T&G siding. I planned to add some 24"x14" wood window sashes across the top, add insulation and some kind of thin paneling, doorskin or such to the back side and trim out the front side with 1/2" x 3" redwood. The fixed doors are no real issue, but what I'm puzzling about is how to make one door openable, but yet weatherized, and without all the traditional opening hardware showing inside. The windows & their framing, the trim, and back panels will add weight, maybe alot. I want to remove all the exsisting spring hardware, so it looks like a room inside and not a garage. I thought about some kind of block & tackle, or manual gears to lift the door, but I just don't know. Also, I want to keep the doors appearing on the outside like regular doors, but modernized, and all 3 the same. Any ideas, (wild or otherwise, I'm open) to lift and open a door like this? I considered remaking the doors into carriage doors, but my driveway is sloped, so that could be a problem for rollers and any type of weatherproofing. I wanted to avoid completely remaking the doors any more than I already am. Thanks for any ideas.
