A method for constructing an armoire within an existing closet space includes the following steps of optionally removing any gypsum board wall sheathing within the closet space; optionally widening the closet opening to more nearly coincide with the interior width dimension of the closet space; optionally raising the height of the closet opening to more nearly coincide with the interior height dimension of the closet space; and constructing an armoire having a body generally in the shape of a rectangular solid that is dimensioned to slide through the closet opening and into the closet space with minimal, non-interference-fit clearance, the armoire having a depth that is about equal the depth of the closet space, the armoire having exterior trim pieces that extend beyond the dimensions of the rectangular solid-shaped body, that fit flush with the closet opening, and that conceal the edges thereof.
