Your estimate seems about right, but I would consider a few things. Most people who do wall construction instead of glass, use studs, not block. The block may be too heavy to be supported by the lanai slab, which does not have a wall footer like the rest of the house. The lanai floor is probably not level, but sloped away from the house. I would install electrical outlets in the wall and definitely insulate the lanai ceiling. Getting a building permit "may" be an issue if you are not raising the floor. This is a very difficult time to get a contractor to schedule the work, which could also cause the price to increase.
