The skullery wall runs the entire length of the bifold windows on the opposite wall. It has the fridge built into the cabinetry one end and the stoves built in the other.
In the middle hidden behind bifold doors that swing right back into the cabinetry is a smaller sink, a dish draw, and a kitchen bench with shelves above and shelves below. This has all the power points and kitchen appliances kettles, thermomix etc. I'm thinking I will do this benchtop in a stone with a black reflective glass as a splashback.
So when the bifold doors on the skullery are open I have my classic triangle with the fridge and island bench. When closed it just looks like a cupboard.
