If you are looking at building a family home for example, then storage space for recreational gear such as bikes, boats and tents should be considered, as should backyard space for outdoor activities.
Modern home plans are created en masse to suit the needs of people who don't want to customise the design of their new home. However, if you have chosen to customise and personalise your floor plan, you can do that too as long as you are prepared to tell the architect what you want. Professional architectural services cannot be replaced when it comes to building a home, so the matter is just to choose the one that suits you.
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.
Exposed wooden or steel beams, flat roofs with large overhangs, and split levels to take advantage of the terrain, are also common accents associated with the contemporary style.
