The renovation of the space will consist to demolish the walls of the entrance area and connect the living, dining room to the entrance. Bringing more natural light into the space. The living and dining area will have a multifuncional new cabinet, where you can have all the requirements that you wanted in one place (workspace, bookshelf, bar, CD stereo, etc.)
The kitchen will remain the same, except for the position of the fridge. It will be demolished the cabinet at the entrance and place the fridge instead. This will make the access to the kitchen more clean.
The proposal of the bathroom is to move all the sanitary pieces to one side of the room, keeping all the pipes in one wall. Including the new location of the Laundry, washing and dryer machine will be into one cabinet and giving you a bigger shower. You can place a bathtub too there if you like.
The bedrooms will keep the same. I suggest to do a multifuncional closet too, where you can have the TV, computer and closet in the same cabinet.
