For example, in the southern United States sunshades and louvers as well as light colored building materials for roofing and cladding help to reduce the heat gain. Sustainable design also means that every inhabitant has access to outside views with natural light and natural ventilation. This sometimes results in narrower floor plans, or articulated plans which expose interior areas to several exposures. The contemporary house plan is designed with the goal of reducing fossil fuel consumption, and providing a healthier and relaxing environment.
Also characteristic of the ranch style are open floor plans which permit rooms to serve multiple purposes. Ranch style houses frequently include separate family, living, and dining areas which can be converted as needed into entertaining or hobby areas, or into extra bedrooms when required. Although a single level ranch house plan with front porch or patio is the norm, there are also split level ranch houses and raised ranch houses which have more than one level of space.
In fact, cottages - by which is meant small, asymmetrical, (usually) rural dwellings of one or two stories and stone, brick, or stucco exteriors, come in a large variety of architectural styles. European-type cottages can incorporate design traits from Tudor, Georgian, French, and Italian architectural styles, with open rooms and high ceilings, fireplaces, and even luxurious elements such as gourmet kitchens, formal dining rooms, private master bedrooms, and French doors. What all cottage styles have in common is their livability - their human scale and design for relaxing, unstressful enjoyment of life.
An open floor plan leaves more room for light, a good flow of energy through the home, and easier access for many people. When researching modern home plans, a lot of people choose open floor plans in the contemporary style just for the sake of sheer convenience. When they have small children, it is easier to see across the home and make sure that their children are safe without having to constantly be in the same room. There are plenty of reasons for choosing a floor plan that is open, but this is actually a popular reason.
