The American country style has several faces: farmhouses with shaker origins, seaside bungalows, Victorian houses of the south states, mountain log houses etc. They have common characteristics by which we can evoke their mood.
Usually the kitchen is in the same open area with the dining table and the living room, separated by a kitchen island. Spaces are wide and open, the ceiling is high. Visible beams and fireplaces are frequent accessories. In the case of a multi-story house, bedrooms and bathrooms are at the first/second floor, communal area, guest bathroom and home office are at the ground level. The house has a garage or car parking, front- and backyard garden and a porch.
Natural materials are the base of furnishing: hardwood floor, painted walls, wooden and wicker furniture, cotton and burlap fabrics, sisal and rag rugs, animal leathers. Ornaments, accessories are frequently antique pieces in original conditions. They can be metal-ware (e.g. trade sign, milk-can), hand-made products (carved box, bedspread) and treasures of nature (shells, driftwood).
Using the national-flag-motif and its colors (red, blue, white) as decorating elements is also a characteristic of the style. It provides high contrasts softened by browns and beiges. Black is a common additional color. Also, the flag is the base of the striped and star patterns. Unique, hand-made, often inherited objects have role. E.g. patchwork and quilted blankets and cushions are typical.
Ladder-back Windsor chairs, rocking-chairs, shiplap covered walls, sofas with soft cushions, reused objects, feeling of nature deepen the country mood.
