I had to get some rough room dimensions from the modified floor plan - instead of harassing the builder and interrupting them while they work on it, I decided to do it in Revit.
Hopefully you can click this to get dimensions. It's got no furnishing/bathrooms/kitchen/laundry etc at this point, shelves, cupboard doors are missing etc - but you get the idea.
Here's a couple of quick 3D view outputs. The perspective is a bit strange in Revit but it gives a better idea of how the roof will look without the parapet.
Front view from a bit higher The black frame windows and sliding doors are close to what'll be used as they're revit files direct from A&L's website. The wooden windows and all the other doors are from Revit's internal libraries (some I've resized, for example the front door is 1200x2340mm)
Rear view. If the slope was shown it might make a bit more sense.
