To keep retaining walls from heaving or cracking, due to hydrostatic pressure, you need to have some release for this pressure. Typically, this is done by installing perforated drain pipe in a bed of gravel along the length of the wall, close to the bottom. The pipe should have 'T' joints and extend through the wall every 6'-8'.
Poor drainage destroys most retaining walls. Build in drainage right in the wall from base to close to the top. A solid footer is necessary for tall walls otherwise they shift as the seasons change and walls collapse. All footers should extend below the frost line.
As close as you want it too. Several considerations to be had: one consideration is the drainage that will collect at the base of the retaining wall, second is the construction type of the building to be protected (what are the building's exterior finishes? are they compatible with the materials of the retaining wall?), third, will the close proximity of the wall allow its construction.
'loose atmospheres': are the build-up and presence of obnoxious gases within the drainage system.

I need some help building a retaining wall, where can one buy good quality materials to start to build a retaining wall.
I suggest you use a Permacrib Retaining wall. They have a an adaptation to give the wall a completely closed face
They plant vegetation, build terraces, and build retaining walls.
The Incas built their roads by using a system of labor called "mit'a," which required citizens to contribute a portion of their time and work to public projects. They used local materials such as stone and gravel to construct the roads, which were then meticulously laid and fitted together. The Incas also utilized retaining walls and drainage systems to ensure the durability and stability of the roads.
There are many places to learn how to build a retaining wall. One can buy software that will design the wall, or one can watch do-it-yourself videos to build a wall. A retaining wall is a solid brick wall, sometimes it holds soil and acts as a planter, and other times it divides the property. To build a retaining wall, one must survey the property, find out the length of space they are looking to cover and decide how many bricks they would need to use in order to build a wall.
A drainage system receives the discharge from storm, waste and soil lines and disposes it into a place less objectionable based on either square feet or fixture units would dictate piping size or a consideration of both by use of interpolation.
Retaining walls are fairly commonplace in construction, but the best way to find a builder with experience is to call and ask a contractor or builder if he or she can provide the service. I would recommend calling local contractors (look them up in the phone book or online) and asking whether they build retaining walls and ask for estimates.
