Thank you hechan. No your cabinets would not go to the ceiling, but the wall of shallow cabinets would. This is because having high up storage is better than not having any at all, and they are still useful for the odd vase or Xmas serving ware etc, Also it is necessary for this walled look to look right. The other column cupboard would do the same, as I like that it looks like a column or structural element and not joinery. However, laminate sheets are typically 2400mm x 1200 so they can only go to this height before. Join is necessary, this is another reason I have placed an open shelf ut on top, ring in a timber toned material, means the Join is intentional, as hiding them often fails. As for the wall, the cabinetmaker would literally stack your carcasses on top of each other, therefore the join once again is only visible at the end, where I have also placed an open unit. No bulkhead is necessary, a 20mm shadow line is left under the ceiling level, in your case the shadow line would be the minimum distance that tour plaster strapping is. The cabinetmaker would worry about this detail, you would simply ask for floor to ceiling. Retaining any architectural features is always a plus for resale, as the homes facade will generally show definite characteristics of the homes era, and this is what potential buyers are drawn to. As a result, people interested in post war, deco or ore styled homes are always grateful for retained period details, however minimal, and infact, the ceilings are the single most appreciated element of a homes design. Ts is because is generally is what gives you the wow factor, demanding your attention instantly upon entering, and they also do not dictate or influence the interior as far as your furnishings goes. You could decorate sympathetically, or contradictory to them, and either will work. The ceiling, floors and windows are the single most desirable elements of period homes, you have the ceiling and the window, most likely beautiful hardwood floors also. These elements provide all the details you need, and a lovely back drop for a simple and sophisticated fit out. Contemporary by comparison is ever popular as mod cons and innovative materials are as equally requested as period charm. Thank you for your compliments. I pride myself on being a pragmatic designer, often good design comes from the need to work within limited parameters, such as yours. But that's easily resolved wi details at address things like maximum ceiling heights with an understanding of material restrictions, ie the panel sizes in your joinery, or understanding what the joiner needs to consider before designing for them. I have an architectural fit out background, and designed many types of firings from showrooms, magazine sets and many more private houses. I'm glad you like it.

I would pop a buffet along the window by the front door & then a rectangle dining table in front of that. There are a few layouts you could do tv/ lounge wise but in the interest of entertaining & also watching tv whilst preparing meals.... I would put the tv on the wall opposite the built in cupboards - not right where the aerial point is though, closer along the wall towards the bedroom door. Then I'd have an L shape configuration of lounges (either a corner lounge or two lounges) with the back of one along the side wall (the wall you look at as you come in the front door), & the other with its back to the built in cupboards (obviously with enough room to open the doors behind it still. Then define the area with a rug etc

There's access to one cupboard on the left hand side with a touch catch. You can see the panel is up off the floor 10mm to allow to open without scratching the floor.

as usual the Real Estate floor plans are not consistent (ie the living and dining area is shown as 4.5 m wide and the kitchen is 4.8?) but, based on estimated measurements the most effective improvement will be achieved with a new kitchen by removing the tall corner pantry and the wide cabinet (and thick brick?) wall next to the fridge and installing base and wall cabinets along the fridge wall with a small base and wall cabinet around to the side of the window and replacing the island with a flat 2400 x 900 counter with knee space and/or shallow storage on the dining room side and drawers for pantry storage next to the sink cabinet i can't see any advantage to altering the laundry and if you don't need the study nook i imagine that the space can be used for extra storage
