NYC Maisonette Renovation

1,100 square foot maisonette in the upper east side of NYC. We would like to maintain the overall plan of the apartment, but need ideas for renovating kitchen, bathrooms, and space planning for how best to use the other rooms/remove closets/repurpose front small room, add a second full bathroom, add a laundry room.

Create a 2 bedroom, 2 bathroom maisonette with an efficient floor plan, maximize light:
1)Need floor plan-- all interior walls can be removed, except for the columns shown.
2)Need interior design plan, including 3D renderings and lighting plan
3)Would like wainscoting in some living areas.
4)Add a laundry room, or at least a large stackable washer/dryer, but would really like a place to fold clothes
5)Maximize storage
6)Add nice closets in bedrooms
7)Second bathroom could possibly be in front room, opposite windows but would like a floor plan with bathroom somewhere else in case it's not possible -- will find out in next few days if it is possible
8)kitchen with electric stove top, steam oven (wall), warming drawer, stainless steel sink, warm organic style, center island, storage, pantry
9)Room for a sectional sofa and big screen tv in living room
10)Mudroom

We would like to keep the NYC character of the unit (for example, sand the wooden floors rather than replacing them), we like mid century modern (west elm), would like to optimize the light in the apartment, we'd like an efficient floor plan with a comfortable kitchen with a center island, if possible, as well as electric stove, warming drawer, microwave, maybe save some money using Ikea kitchen cabinets.
