The platform structure incorporates the continuous perimeter deck which is a construction and maintenance blessing on a super steep site.

Steep Slope #6

Steep Slope #6

Straight topo line: This long 1 story layout follows the construction concepts consistent this series.  Recognizing that adding footage, if not accomplished by going up as is the case in design #5, then continuing to run along the topo line is the only choice. Pushing a design farther out over the sloping terrain is not an option.

Really big platform support system: This idea best illustrated in the foundation 3d image. This platform structure uses a series of independent footings and independent 4 part braced posts. The independence of these footings (compared with the continuous footing in design #5) allows for a site demanded change in height which is highly likely in a long run such as this project has.  The centers for these independent footings are similarly flexible. Cross joists for floor and insulation (2×10) and for decks (2×6) complete the working deck for all construction and future maintenance above. Working off a steep and or rough ground plane can be a serious handicap. The platform idea, once built, eliminates that handicap.
