Ironwork doesn’t have to be painted black

In December 2014 Arroll and Snell, architects for Shrewsbury Roman Catholic Cathedral, asked TOPP & Co. for ideas regarding guard railings and gates to a new entrance and external staircases to the cathedral, as part of a major redevelopment of access and circulation within the building. The cathedral was opened in 1856 and is in what is now known as Victorian gothic style. The interior was designed by Edward Pugin, son of his famous father Augustus Pugin, well known as a champion of the gothic revival, whose most famous works include the interior of the palace of Westminster.

The work was commissioned as a design and build contract, rather in the manner of the commissioning of a work of art. This approach was of course commonplace at one time for ecclesiastical work, when an artist would be asked personally by the architect to fulfil the brief. We thought it might be fun to design the new ironwork to be cast, rather than wrought, and this seemed to make sense for a number of reasons.

Cast iron architectural detail was at the height of its fashion in the mid nineteenth century, and its bulk goes well with the massing of the gothic detail carved into the masonry. The scheme lent itself well to repetitious ornament, the railings being divided easily into discreet panels. Repetition renders castings more economical, as the original, and expensive, carved pattern can be used many times, the castings being relatively inexpensive. Finally cast iron has an excellent resistance to corrosion, and will in all probability outlast the stonework.

With broad experience of design in cast iron, we asked our designer Bethan Griffiths of The Ironwork Studio, to prepare a number of alternative design schemes, from which the client could make a choice. Each of the designs was based upon some element of Pugin’s interior, and had to bear in mind the appropriate building regulations, which forbid any gaps in the railing which would pass a 100mm ball.

The design style duly selected, Bethan went on to work up the design idea into railings, gates and handrails, and do detailed workshop drawings from which the pattern maker could work. It was not until the iron castings were completed by the foundry that we could take them into our workshops for machining, fitting and painting. Meanwhile on site the stonework was being completed by the masonry contractor, ready for us to fix the ironwork into position.

Where possible, in the spirit of work of the period, fixings are concealed so that there are no visible bolts or mounting plates. Equally no site welding was employed, frequently a sign of a lower class of work.

It is easy to fall into the trap of assuming that all ironwork should be painted black. In fact black was seldom chosen prior to the nineteen twenties, and so would not have been appropriate to a building of this period.The architect was keen that the colour of the ironwork should reflect the symbolism of the Catholic faith, and blue was chosen as it represents the sacred virgin, and was a colour extensively used elsewhere by the Pugins, father and son.

The work was completed on site in November 2016 and if well maintained with a coat of paint now and again, should last for a century or more without major overhaul.
