Much better.

my concern with the windows was to make sure that there is a window for light and ventilation for each separate space but it should be quite simple to build shelves to suit the windows in the wiw but what is the size of the windows in each room? that is width, height and distance above the floor?

if the goal is to make a more spacious WIR my suggestion has a HIS and HERS arrangement with more than 3m of extra storage wall, more standing/dressing space and a brighter daylit room and there's the separate toilet, double shower and generous linen storage and, although it's shorter, the vanity bench is still over 2m wide with matching mirror doored wall cabinets but there's also and out of the way standing space next to the shower that doesn't have a wet floor or block access to the toilet ..i've included a copy of the original and new plans for comparison

And to answer your question siriuskey. Yes the front room has been opened out into a verendah. This room got really hot in summer so wasn’t working as another living space. We’re restricted to what we can change at the front of the house as we are in a heritage area. We can make changes without a DA if we don’t change the front of the house. Agree we can change a lot with a wooden house, but I think we’ll be restricted on reusing windows. All our casement windows are original glass from the 1930s so won’t be to modern building code. If we move them, they’re gone. However replacing with modern glass would bring more light into the home. We’ve put fans in all rooms and always have the French doors open in bed 2 so light and ventilation haven’t been an issue. Might become so if we put a moody teenager in there though!
