I got a program to make house plans and made floor plans for three houses. My computer refused to let me just scan it into deviant art so I had to go the print it out and scan route. Anyway here are the links to the various house plans and an explanation on each one I made.

Spinners End:

Spinners end, a small home in a working class town. It was updated to have a bathroom and electricity but it still was a grim place for a boy to grow up in. Still Severus Snape chose to live here and makes it as cozy and home like as he can.

Grimmauld Place:

Grimmauld Place, a dreary home that once was the home of dark wizards. I created this house plan based on a townhouse design of Victorian times. It is based more on one of the many American townhomes from that era I have seen but I am sure it is similar to their English counterparts.

Potter Manor:

Now I did this manor this way as Harry said a few things about his home in the epilogue of DH. So I took the liberty of doing a small hall with only five bedrooms, three levels and a large library. This house has every modern muggle convenience along with all the magical trappings. A muggle could walk into Potter Manor and feel right at home with the “electrical” lights, the stereo, TV and other modern trappings
