Selecting the right type of timber is a key part of designing the observation tower both aesthetically and structurally.
As can be seen in the pictures to the right, there are several different types of wood, and far more than are shown in the images.
It is important that the types of wood used or not too different from one another too often. It is best that they compliment both the park and each other. This may mean using colours which are similar to the surrounding trees.
I am already planning on perhaps using different colours for structural elements compared to other elements such as cladding, but the types of wood used aesthetically will depend on the design which I take forwards. This post and it's images and research will come in very useful.
