not to be snarky & excuse me if I missed it, just curious, if it needed nothing, why are you doing so much? fwiw - I think it looks great, what you're doing
As title says.....Grand Designs. Never thought I would ever have the means or even opportunity to live out what is genuinely a childhood dream. So what not

More steels have gone in now, and you can start to see the shape of the atrium over the kitchen and the spine of the stairway that's going to connect the two upstairs gables.
This will be double height atrium in the kitchen that joins with the atrium/gable at the front of the house. Getting quite exciting to see the 3D space take shape.
Kitchen design is also now done, deposit paid. The rendering doesn't show the double height atrium, so I've added my own 'preview' of what the glazing will look like above the island.
