Cottages are traditionally homes of simplicity and comfort, but recently, the style has upgraded in a big way.

The typically small, old-fashioned residences have gone from being overlooked and under-designed to being reinvented as sleek, modern homes for the 21st Century. Many designers are now taking the simplest cottage layout and transforming it into a vacation home or even mini mansion.

Many of today’s cottages are fully equipped with extravagant and eco-friendly kitchens, bathrooms, and bedrooms, and other design elements that breathe new life into an old idea. Here, BUILDER has compiled some of the best cottage designs from across the country that are both stylish and comfortable, formal and functional, featuring chic decor and simple, refined spaces.
