Modern Vertical Deck Railing - Most sundecks past the very simple deck included with many houses will be custom enhancements to an existing structure. This means your new sundeck doesn't begin with the very first nail, but rather, with the very first pencil line made in your sketchbook.
Whether building your self or hiring outside, initial planning should be done by people who will use the deck. A good designer can assist with this, however most homeowners have a pretty good idea what will work at this first design stage. Take a couple stabs at it. You may find yourself doing arcs and odd angles, but it's all in pencil so play with it.
While you are outside walking the shape or "footprint" of your favorite sketches, consider amounts, or " elevations." Raising or lowering a deck degree in places by even one measure can add greatly to a deck appearance and feel. After an approximate idea of the deck's footprint appears to function, think about points of access into the deck if any, and if stairs are needed.
Considering elevations in decks is essential to get a few different reasons, the first being that most deck surfaces have joists supporting them. An even more pressing thought is railings. Generally, if a deck surface is over two feet above ground, a railing is required. If over six feet, then a greater railing is necessary. In my view, any altitude change on a deck should be obvious.
