Recámara principal Adición arriba del garaje y en la parte trasera de la casa para crear un acceso a la planta superior

Concepts welcome! Just need some quick ideas about how to add an addition above the garage for a master bedroom and bath and reconfigure entire inside for an open floor plan, kitchen with island, mud room, great room. Addition should also extend the backside of house with a two story ceiling to allow for a traditional staircase, there is now a spiral staircase in the center of house. completely rework the floor plan while adding on the above the garage and back (L-shaped-see pics) Can be hand drawn and sketches work too.

Do not have to do all the drawings, just ideas that convey this concept. Do not have to spend too much time, thus a lower budget for this. Just want to see if this project is feasible. no architectural drawings necessary, this is for concept only to be used for ideas. There are several concepts attached as examples but none of them are really good and could use another set of eyes/designer input. This should be just for fun and should not take hours to get hand drawn concept on paper as exemplified in attachments.

new staircase, open floor plan, one office lower level, new entry or foyer facing front, new mud room/laundry room, can extend garage also. Abondon exsisting bathrooms and place in a better location. Powder room/or small shower on first floor bath. two full baths upstairs (maybe three) great room with high ceilings, Add a fireplace facing back wall. LARGE kitchen island. 5 bar stools. Nice welcoming entry off in front of house, can use space from the wrap around porch. Can redo wrap around porch to make more useful. upstairs: 4 bedrooms/three baths. big master bath, separate closets in master. Deck off of master.

completely rework interior space by adding to the addition so the space seems like one. the goal is a 4 bed/3.5 bath house with large garage, open concept partially, open to backyard, new windows, better floor plan. get rid of spiral staircase. most walls have to go to start over.
