House plans with dormers can provide both functional and aesthetic value to a house plan. Dormer house plans are seen in many architectural styles, from Farmhouse to Craftsman. A dormer adds architectural interest to the homes facade and may be a decorative adornment or a functional addition to bring light into a bonus room or rooms with high ceilings. Classic Farmhouse or Cape Cod home plans will feature multiple dormers on the front facade. Showcase French Country architecture with an eyebrow or shed dormer.
