Exterior and Interior Design
Exterior and interior design encompass not only what the architectural structure looks like but the furniture, flooring, paint and decorations suitable for outdoor or indoor use.

Exterior doors provide security and weather resistance and include front- and back-entry doors, sliding glass doors, French doors and patio doors. Exterior doors are typically made of steel, fiberglass or wood and are available in different sizes and styles, such as panel and glass designs or grille patterns. Interior doors function mainly to keep noise out and to provide privacy, especially in the bathroom and bedroom. Interior doors are typically made of medium-density fiber board and composite wood and may be hollow or solid. Types of interior doors include louver doors, French doors, bi-fold doors, swinging cafe doors and pocket doors.
Exterior paint is alkyd or latex based and comes in finishes including flat, low luster, semigloss and gloss. Interior paint is most commonly water-based latex and is available in a variety of finishes, with the most common being flat, low luster and semi-gloss. Flat finishes hide imperfections and are best used in rooms that aren't used often because they're harder to clean. Low luster, also known as eggshell or satin, paints have a slight sheen and are not good at hiding imperfections. A semigloss stands up to light scrubbing, so these paints are ideal for kitchen and bathroom walls and for exterior trim work and casings. Gloss is the toughest finish and is best used on door jambs, window casings, shutters and other trim work.
