Thanks all, much appreciated!
It's a small miracle these turned out right. Since January I have new spectacles with self-colouring glasses. Comfortable but almost impossible to use with a camera EVF or rear LCD.
I forgot to bring my normal spectacles so composition with the dark view was very difficult.
Paco, what an exact description of my attention. Indeed colours, shapes and textures that's the focus of my photographic interest especially when shooting architecture.
No personal connection on this series, just wandering around looking for places of interest.
A note on the first image. The red tiles on the building applied during the build were made from heavy ceramic material. It turned out these were too heavy so they started falling off the structure. All tiles had to be replaced with lighter plastic ones. Very costly and someone is bound to have been blamed for that!
