This lookout structure has been designed to rest on the corner of a wall and support a spire exceeding the ridge height of the adjacent building. The base section fits under a handrail and leans against the corner of the wall and is held in place by the weight of the spire. Both sections are made from aluminium profiles that are both light weight and stiff. The base section uses an angle profile to fit the geometry of the wall corner and the spire uses a square hollow section so that a steel rod can hang at its base and securely balance the structure. The spire is connected via a pin joint so that it hangs vertically but allowing movement to reduce wind loading.
