Anyone know of inexpensive cad program with a really flat learner curve? Or better, a site where one can play with pix? It doesn't need to be anywhere of the caliber of a high-end cad program, just give me a sense of whether this could work. I tried a drawing program and that didn't work. Tried printing it up and drawing on that, but this wasn't very helpful either. I'm considering an addition on the end of my house, a little bump-out to extend my son's dark small bedroom. He's in the NW corner, one small window. I thought an 8x12 extension, shed roof, one room with a loft would give him a little breathing room, fresh air, a view. Maybe build a little wrap-around deck to the south and west. Then I could steal part of his existing bedroom for an entry-hall closet. Use the header over the existing window for a pass-through door into the add-on. Offset it a foot or so back from the existing front of the house so it looks like it grew, not like it was patched on. Roof would match existing roof in materials, angle, but tie in to house under existing roofline for the same reason. I'm thinking if I keep it to complementary proportions in terms of length to height, it might help. I may never get around to this--just playing with ideas right now, but it's an idea I've played with for awhile. I'm having a hard time visualizing how that would look from the outside. I think the decks on the east would help visually balance it, but OTOH, it might look just crunky. Can't guess. On the other hand, there can be downsides to getting one's teenagers too dang comfortable . . . Any input appreciated.
