I built a 15 by 15' deck above a 20 by 20' deck Solely by watching How to KZfaq videos of each process of building a deck the only experience I have with construction was in high schoolAnd I am currently 54 years old. I have a lot of smaller videos of the process however I do not know how to piece them together to show the Complete process but I built not entire deck by myself in 3 weeks. Tell me what you think how did I do it is up to code according to every video I've watched on KZfaq and believe me I watched several so to everyone who has posted a KZfaq video on how to I greatly appreciate the information I had a Estimate of 34K to built this deck I built it for less then 5K.
