ok as a builder,, i recommend a stainless kitchen, counter, appliances, even the fan,, its easy to clean and more permenant than other optioons,, also go with commercial appliances if you can , or if you are a cooking family,, would love the extra burners etc,,, also master bath,, shower seperate with a larger tub. double sinks and a walk in dressign area off bath that also has access to br. make sure there is at least one out let in dressing area for iron, hair dryer etc,, and in bath. i like built in cabs and storage in bedroms,, for tv etc? a walk in pantry is a nic efeature, preferably with a freezer figured . i would put laundry on same leval as master bedroom... easier to let kids transfer clothes up and down than mom and dad,, or have a dumbwaiter installed from laundry up to upstairs. avoid carpeting areas that get high traffic and those areas where carpet tends to get stained or damaged. throw rugs are a better bet. get windows that fold in for cleaning, and are easily operated. also make sure master bath is not only \bath on ground or upper floor, put the extra bath in, even if its just a half bath off of living area, you will appreciate it later. if 2 story, avoid carpeting on stairs, or a really slick finish, and make suer handrails are on both sides..... i personally would look into a metal roof last s much longer than composite shingles and less easily dmaged by weather
