The floating foundation deck system sits at a height of 13" when properly assembled with 2x6 support boards and decking. Your building site needs to have this clearance plus a 1/2 inch for a space between the deck and the doors threshold. If you need a deck that is lower than 13 1/2" due to the placement of doors or other structures on your home consider building with these methods.

1. You can build directly on top of patios using blocks of wood or stand off brackets between your support frame and the concrete. We do not recommend this method for areas larger than 20 sq. ft. Click here for a good example of building over a concrete stoop.
2. If the area to be lower than 13" is greater than 20 sq. ft. you can build your deck with a landing around your door. This will allow you to step out of your house at the current ground level, and then step up onto the deck that can be built at the proper height of 13". The image below shows one home owners solution, your landing can be any size needed.
