Images from Gaudi's Casa Batllo. This spectacular house was the main reason I wanted to revisit Barcelona. I came here with a friend of mine a few years ago and absolutely loved it. I couldn't wait to visit again and soak in the amazing architectural and decorative details. So fluid and ergonomic. A lot of the design features in addition to being colourful and whimsical are clever design features that improve usability of the house. The tiles in the centre lightwell change in saturation as they flow through the building - giving the impression of more light in the darker areas of the house.
