Hidden Tension: Furness's Hockley House
If one looks closely to the underside of the tympanum, one notices three grooves that seem like a tri-partite stone moulding. The middle groove, however, is just slightly darker. At closer inspection, it is clear that it is not stone at all, but rather an iron beam in tension inserted in the intrados of the arch. That's how the tympanum is supported. I returned with my camera to take a close up of that detail.
I include here a photo of the Hockley House porch for those that have never seen it.
here. The tension rod here adds another wonderful piece to the discussion. Soon after using exposed steel beams in his Broad Street Station, Furness used it in a house around the corner, which I will discuss later.
