Submit your plans to the Architectural Control Committee. The Committee is really not concerned about the interior layout of the house, only how the exterior appears and that the construction meets the guidelines of our covenants (items c, d, e, f among others in our covenants). These items, along with others, will be addressed in the Approval Letter issued to the contractor or lot owner prior to construction.
You may start grading on your property, however you may not start any slab/foundation work until your plans have been approved by the Architectural Control committee and you have a signed letter of approval from the committee.
