This step by step diy project is aboutground level deck made from 2x4s plans. I have designed this deck so you can build it entirely from 2x4s. Considering that you will use 2x4s for the joists, at a 12″ span, you cannot make the deck larger than 8’x8′. As you will see in this project, this light construction doesn’t require complex tools or carpentry techniques, so any person with basic skills can get the job done in just a weekend. Make sure you read the local codes, so you comply with the regulations.
