This is a incredible product - well designed, beautiful and sturdy. But it was a BEAST to assemble! We spent one day organizing all the pieces and putting like pieces together. It was time well spent! My husband and teenage son and I worked for 3 solid days on assembly. I highly recommend using the BILT app because it gives detailed instructions and really assists and understanding each step. If we would only have use the provided instructions, I don’t think we would have figured it out! Even after the huge job of constructing it, we are so happy with the finished product and we would highly recommend it to anyone who would like a high-quality and gorgeous playhouse for their family.
