THE PROPOSED LAYOUT OF THE APARTMENT IS COVERING ALL OF YOU REQUIREMENTS. IT IS A COMPACT AND FLEXIBLE SOLUTION.
I ADDED A WALL BETWEEN ENTRY DOOR AND SOFA SO YOU CAN HAVE A DEFINED ENTRY SPACE WITH HANGERS AND ALSO A PRIVACY WHEN THE ENTRY DOOR IS OPEN.
IN THE LIVING AREA I HAVE USED THE REFERENCE FOR SEPARATING THE SPACE, SO THAT THE GLAZED PANELS, SLIDING AND AWNING DOORS, ARE PLACES SO THE SPACE CAN BE USE AS FLEXIBLE DEEPENING THE NEEDS.
THE HOME LIBRARY IS GIVING THE LIVING ROOM AN EXTENDED LOOK SO THE SPACE LOOKS BIGGER AND EVEN WHEN IT IS CLOSED WITH THE GLASS SLIDING DOOR, VISUALLY THE LIBRARY STILL BELONGS IN THE LIVING AREA.
THE TV ZONE IS AWAY FROM THE ENTRY AND THE PASSING TROUGH SO IF SOME IS WATCHING TV IT WON'T BE DISTURBED BY SOMEONE THAT IS PASSING BY.
I HAVE SEPARATED THE KITCHEN FROM THE DINING (AS YOU HAVE REQUESTED) WITH GLASS PANEL (AWNING DOOR) SO YOU CAN HAVE VISUAL CONTROL OVER THE SPACE AND YOU CAN USE THE NATURAL LIGHT. YOU CAN OPEN THE AWNING GLASS DOORS BETWEEN THE KITCHEN AND DINING AND EXTEND THE TABLE SO YOU CAN HAVE 8 TO 10 SITS FOR DINER.
THE LIVING ROOM, THE DINING AND THE KITCHEN, ALL ARE FACING SOUTH.
YOUR STUDY SPACE IS TAKING THE CENTRAL POSITION OF THE APARTMENT SO YOU WILL BE NEAR THE KITCHEN OR THE L'DRY IF YOU ARE COOKING AND WORKING AT THE SAME TIME. IT IS ALSO NEAR TO THE BOOK SHELVES (THE HOME LIBRARY). IF THERE IS A MESS GOING ON IN THE STUDY, IT WON'T BE IN THE VIEW RANGE FROM THE LIVING AREA. YOU CAN ALSO HAVE AN INDIRECT SUNLIGHT THROUGH THE GLASS CAVITY SLIDING DOORS.
THE SLEEPING AREA IS SEPARATED WITH DOOR FROM THE LIVING AREA SO YOU CAN HAVE MORE PRIVACY, SO THAT THE GUEST TOILET IS IN THE LIVING AREA AND LAUNDRY IS A PART OF THE SLEEPING AREA AND, IT IS NEAR THE THREE BEDROOMS (SO YOU DON'T NEED TO GO OUTSIDE ON THE BALCONY AND CARRY OUT THE L'DRY ALL ALONG THE APARTMENT).
I HAVE PLACED THE TWO ROOM FOR THE KIDS SIDE BY SIDE, SO THEY CAN HAVE AN ADJOIN TERRACE AND ALL THAT SIDE OF THE APARTMENT, INCLUDING THE BATHROOM, CAN BE "THE KID'S WING".
I HOPE THAT YOU WILL ENJOY ALL THE PROPOSALS.
