The House of the Future will offer quite a few modifications from the house of the present*.
Note the excessive width of the hallways in the House of the Future. These hallways were designed to accommodate wheelchairs, Hoverounds, and Gay Pride parades.
This sample floorplan includes a single bedroom. Such a design detracts overnight guests by ensuring that only one person/couple is sleep-enabled at one time, and does not have to face the prying eyes of anyone else; the House of the Future discourages casting judgment on others. Please note that the term "Master Bedroom" is merely an architectural convention, and does not at all imply any kind of in-house racial/gender hierarchy.
*So that everyone feels welcome in the House of the Future, it is vital to offer a variety of designated bathrooms. Here is a list of restrooms that every House of the Future should have in order to avoid offending guests.
