Can our lessor make changes to house without our knowledge?

. A little background before you call us stupid and say, DUH, what did you expect. I am ill, I have been for 3 years, 2 years ago, they said this is the end for you, went home to go in comfort. Well, I never went but our credit did. I was gainfully employed and then was knocked on my and lost my benefits. Basically, same story millions of others are suffering from. Bottom line, we are just starting to be able to reestablish our credit. No place , loan or rental property would take us because of medical debt. This company does not do a credit check, they do income verification and criminal history. You have to make a minimum of 52gs to live in this subdivision. They dont check credit cuz they claim even good people fall on bad times. Maybe they saw us coming!!! We ARE NOT bad people and my husband makes ok money, about 70gs. Stilll we never could find a place to live till this past october. There is a subdivision that says Luxury Homes for Rent. We stop, just to see. The houses are by no means luxury, but they are cute quaint little houses. Each future home is atop a five acre plot. They had one display home that they showed us, a two story and another, a one story in the process of being built. We chose the two story home, they said the house they would build for us would be EXACTLY the same, after all they were using blueprints right?Now as they are moving along , they have changed the house drastically. They omitted a storage closet for coats and vacuums etc., their reason for that, the house is on a basement instead of a slab, we apparently dont need that space upstairs. When we asked about it, they said they could build us one in, but it would cost us extra!! The upstairs was to consist of two bedrooms and a bonus room. The bonus room was to be an unfinished room, no carpet and no paint, basically just a storage room, a big one at that. The dimensions in the house they showed us for the bonus room were 28'9" x 8'11". Now in our house the bonus room is 28'9"x 12'8". This increase in space drastically reduced the size of the bedrooms, by about 3'11".The landlord says he changed it for his resale value, so that the bonus room could be turned into two more bedrooms when and IF he goes to sell. Keep in mind he is not finishing this for us though, he just increased a giant waste of space, at our expense. The display home was about 1550 sq. ft. not counting the bonus room, with it its about 1800sq. ft. I am beside myself, and if you ask me a 5 bedroom house crammed into 1800 sq. ft. with 2.5 baths is not a selling point, its a motel!!!! My question I guess is, can he do this? We really feel like we are getting screwed, we are paying 1600 month for rent, and more than half the upstairs isnt even going to be functional. What can we do??? We wouldnt have signed this lease if we were just seeing this house for the first time, we would say thanks but no thanks, the layout is stupid!! Please help!!
