2. Pay attention to indoor/outdoor integration, i. e., easy connections to sheltered outdoor space or the back yard. Look for convenient doors to a patio or porch: the outdoor connection allows a house to expand in good weather, connect to the site and landscape, and prevents it from feeling like a prison.
Plan 137-107 The front porch is deep enough for outdoor living -- which also adds curb appeal.
Plan 479-11 The island is multi-functional and in scale with the kitchen.
5. The "Goldilocks Problem" is when Entries, Hallways, and Family/Great Rooms are too big or too small or have ceilings that are too high. It's all about proportion and practicality -- a two story entry that makes you feel you have entered the bottom of a well does not make for a pleasant arrival and is wasteful. On the other hand, low ceilings can make smaller rooms feel cramped and are especially regrettable when stairs seem to disappear into them. A stairway should not make you want to duck before you take the first step. So, look for plans where room height is proportional to room size, and where the stairway is a light source with a double-height ceiling over it and a window at the upper landing or high in the stair wall.
Don't buy a house with a great room that only has one window. Or consider expanding the great room to create a window bay so that you will have daylight coming from at least two sides. Wall-washing skylights can make a room feel taller and more spacious.
Plan 901-1 A great room with daylight from more than one side feels more spacious and welcoming.
Plan 48-642 Efficient garage-to-kitchen access means no convoluted circulation.
Plan 132-228 A walk-in shower feels more spacious than a tub-shower.
11. Details are important: Instead of cutting costs by lowering quality in windows, doors, hardware, flooring, which are the most visible and touchable elements of a home and establish its character, reduce the square footage. This is a way to lower costs instead of compromising on materials and fixtures.
12: When building from stock plans, avoid making modifications in the field without consulting an architect or designer. He or she can make modifications that won't compromise the original design.
