These hand crafted wood gates are made to match all other wood elements in the courtyard. Even the hot tub in the far background is a match because of type and color of the wood.
This is a good example of unity and repetition in garden design. While there are a lot of different elements that make up this patio design, the elements themselves stay consistant with each other.
Imagine the difference if the garden gates were Redwood, the canopy was a dark wood, and the hot tub in the courtyard was a light wood. It may not be noticable as a bad thing but would not be a unifying element that compliments the courtyard garden design and helps tie everything together.
