This project cost us about $850CAN and took us around a week (5ish hours a day) to complete. My husband and I are definitely not carpenters so it's not perfect but it's pretty amazing :)
we made several alterations to the plans including making the bottom bunk larger to accommodate a double/full size mattress. We also made the "door" to the bottom bed larger with an opening of 30". Another alteration was we dropped the mattress cleats to 9" off the ground so that the mattress dat down in the bed. The bed is for our 2 year old so we thought she would have trouble getting in if it was much higher. This eliminated the storage area underneath but she has a large closets so we didn't think it would be an issue.
The plans were great and pretty easy to follow. We are over the moon with how it all turned out!
