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.
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.
Ranch style homes are usually long and low with a bare minimum of interior and exterior decoration. The idea is to create a casual and informal lifestyle, usually with access to the outdoors via large plate glass windows, sliding glass doors, and patios or decks. Ranch style home plans normally imply a single story construction with a low and long roof line, with a cross- or side- gabled or hip roof.
A few questions you will need to answer will include: how many bedrooms, whether or not to have a family room, if a separate study room is valuable, and if internal garage access will be important. Plans come in both 2D and 3D versions for you to review before building begins. You will want to go over these with a fine toothed comb, as changes are much easier to make on the blue prints then once actually constructed on the ground.
