I have a lot of books, so I wanted two walls of my office / library to have floor-to-ceiling bookshelves. I checked with a few companies that deal in premade cabinetry. None of them could handle the 9' ceiling height (pre-made cabinets only go to 8'). They also don't make corner bookshelves. I was referred to Schiller by several people, and they were great. They gave me an estimate along with a computer-generated picture of what the shelves would look like when done. They were a little backed up, and it was a big project, so it was 8 weeks until the install happened, but their 3 man install team showed up right on time and got everything put in in one day. The shelves look great and are really nicely finished. No flaws anywhere. Also, the price was almost the same as what I was being quoted for the 8' high shelves from the pre-made cabinet companies.
