Andrew Todds presentation of his wooden neo-Elizabethan theatre in Northern France was a highlight at the end of the 6th.International Wood Construction Convention held in Lyon last week. April, 23 is usally considered as the day of Shakespeares death. No doubt that the architekt would have prefered this date to inaugurate the theatre, instead of the week-end in June following the Brexit referendum. This is the presentation of the project by Andrew Todd, printed in the 500 pages document which has been distributed to the partecipants of the Convention in Lyon.

In the year 1520 a remarkable wooden building was erected in mainland Europe under the orders of the English King Henry VIII. Brought across the English Channel as a disassembled frame, the building had a specific diplomatic purpose. Called ‘the banqueting theatre,’ it was destined to entertain and charm Francois 1er and his court at the Field of the Cloth of Gold camp near Calais, on land which was then under English sovereignty. Henry’s hospitality had the aim of avoiding war and resolving complex questions relating to the Roman Catholic church. As anybody who has watched the television series The Tudors will know, the summit ended badly -perhaps because Henry and Francois ended it with a personal wrestling match, which Henry lost. The two countries were estranged within five years, Henry broke from Rome, the rest is history.

There is only one graphic record of the event -a painting now at Hampton Court- which is a rather summary, almost cartoonish depiction rather than an accurate portrait, executed for public relations purposes rather than documentation. We know some details of the building thanks to contractual and eyewitness records which were brought to my attention recently by archeologist Julian Bowsher of the Museum of London. What they reveal is quite extraordinary. We discover that the form of the Shakespearean Theatre -which we know objectively from similar accounting records and only one second-hand sketch made 75 years later- was first tested as a prototype in what is now Northern France (there was also another similar building in Calais). The structure had three galleries, was circular in form, and -as befits a temporary building- was clad in canvas with a ceiling painted with various regal and cosmic iconography. We also know that it was technically advanced, the structure being designed to be dismantled and moved -as would be one of the future ‘permanent’ theatres in London, the 1576 Theatre in Shoreditch, which moved from Shoreditch to Bankside in 1598, upcycled as components of Shakespeare’s Globe.

Plus ça change…. Henry was attempting to avoid a kind of Brexit just as David Cameron is currently, desperately doing, and Europe’s borders were as contentious then as they are now. Other temporary wooden structures in a very different kind of camp at Grande-Synthe today house refugees whose wish to migrate to the booming British economy is constrained by the Le Touquet agreement shifting the Franco-British border south of the Channel, an accord which may go by the wayside in the case of a no vote in the upcoming referendum. We can perhaps expect to see -in a post-EU future- an armada of desperate sailors arriving on British shores in the hope of a better future, or to be reunited with their families, just as we now see them lunging dangerously from Turkey to Greece in overcrowded dinghies. In the meantime, in domestic French politics, the far right -advocating a Frexit- has made significant gains locally, taking 12 of the 80 seats on the local council and almost winning the Nord Pas de Calais regional elections. Their ideas -against open borders and migration- are taking root in the political discourse of both right and left mainstream parties.

I want to retain two thoughts from this introduction: architecture obviously has an important purpose as a conveyor of power and diplomacy, and wooden architecture has a specific function in this, allowing fast erection and easy transport across borders and geographical boundaries.

When my practice was asked by the Conseil General du Pas de Calais to build France’s first neo-Shakespearean theatre in 2013, it was not apparent that the project’s hand of friendship extended to Britain would be sullied by the complexities of Brexit, the Jungle camp and the rise of the Front National; the eerily prescient banqueting theatre -situated only 30 kilometres from our site on the Cote d’Opale- was also a deeply buried footnote to history of which I would become aware only later in 2014. An added accent was given to this situation by the fact that Henry VIII’s descendant, Elizabeth II, touched the model you see exhibited at this gathering, giving it her blessing and approval as a talisman of Franco-British friendship.

I had been studying the Elizabethan theatre for twenty-five years, fascinated by its urban presence as a vernacular icon, its strange status as an indoor-outdoor building, and - above all- by its perfection as the soil in which Shakespeare’s mercurial thought would take root. Rejecting an image-based scenography, it privileged the ear and the imagination, and created a society in miniature united around the action. Its most famous manifestation -among six that were in use four hundred years ago- was not called The Globe lightly: Shakespeare explicitly references in his writing the building’s capacity to capture a world in miniature, channelling all the violent currents of discovery and change which characterised his time (as they do ours). This idea was perhaps taken even further in the cosmic diagrams apparently painted on the theatre’s stage roof: a miniature, dynamic world in a harmonious universe. I had already broached this subject in the book I wrote in collaboration with Peter Brook, The Open Circle, and in the project I conceived for his daughter Irina and Thierry Mandon, then mayor of Ris Orangis, now Minister for Higher Education and Research.

Our initial intuition for the Hardelot project touched on two subjects which are now present in the finished building:

Firstly, Shakespeare’s carpenters used simple, vernacular forms carried to perfection; his theatres have something in common with the timeless, distilled structures of Mies van der Rohe (who admired these Renaissance buildings). We asked ourselves: what would his pragmatic, inspired builders have done with the wood construction techniques available today?

Secondly, the terrestrial globe of Shakespeare’s time was fluctuating, its horizons expanding at great speed with the opening up of the Americas, Asia and Africa: his work is replete with the exotic limits of his world, taking in our contemporary geopolitical hotspots Libya, Lebanon, Greece and Turkey, and projecting beyond these into imaginary worlds such as the island of The Tempest. Our globe -what we reductively call ‘the environment’- is now totally finite, its resources overexploited, its end in sight. How could we possibly build today referencing his Globe without acknowledging the condition of ours?

What, then, is our correlative for the rigourous green oak frame of the Globe, the Rose and the Hope? And how do we conceive a Globe for today, acknowledging our particular and tragic relations with the planet?

In the latter case, we took a radical approach to the building’s systems, using entirely natural ventilation for the first time in France in a complex building. Let me be clear: there are no ducts or fans to move air throughout the auditorium: prevailing winds, rendered into negative pressure at extract vents on the roof, work in harmony with the natural stack effect of the very vertical volume to draw large quantities of fresh air through the auditorium using passive displacement methods. The building’s invisible concrete infrastructure (housing toilets, plant and backstage facilities) serves to temper the air in a thermally inert masonry plenum under the entire stage and stalls balcony. Wind tunnel-tested ventilation cells are individually controlled to balance differential air pressure at the building’s base with negative pressure at the top. Air movement is controlled by insulated mechanised louvres. Passive nocturnal cooling is facilitated by gentle exhaust fans in the ceiling. This system was developed and realised jointly by our engineers LM, Contractor Hélène Bécu (Engie) and the Soufflerie Gustave Eiffel in Paris.

In the former case -the building’s body- it was immediately obvious to us that crosslaminated timber offers unique benefits of precise fabrication, carbon sequestration and fast assembly, similar to Shakespeare’s system-build frames. However, it is generally used as a replacement for concrete in typical construction build-ups: insulated outside and finished inside with other materials for reasons of assembly and fire-rating. It is also generally produced in flat panels, not playing along with the wobbly parametric game of contemporary architecture.

We wanted this material to be the very flesh of our building, an ambition involving two innovations which are entirely original in terms of their scale and generalisation in the building: there would be no finish materials or fire treatments, and all the wall panels would be vacuum-formed to the curved geometry of our building. One of the large-scale manufacturers using this process responded initially without reservation concerning the curved geometry, a signal which was fundamental for our confidence in pursuing the scheme in this manner.

Our fire engineers Cabinet Casso -represented by former fireman Christian Roux- played along, as did the Bureau de Controle Dekra and the Departmental Fire Brigade led byLieutenant-Colonel Hanse: by adding compensatory measures above requirements (such as smoke extract and additional exits) we were able to avoid flame spread treatments for the walls of the auditorium and foyer (escape stairs, lift shafts and exposed undersides were treated with intumescent varnish).

This opened the way to a totally pure, almost Miesian detailing of the building, where structure would become rhythm, and also surface and separation. This is particularly apparent in the access corridors for the theatre, where the five crossed layers of spruce in each panel are left exposed in the heads of walls, and doors are set into the CLT without surrounds or casings. There are no skirting boards in the exposed CLT areas of the building, floor finishes slipping under the structural panels into a recessed footing detail. Naturally this approach does not permit millimetric accuracy -in spite of the claims relating to CLT. There is an honest chunkiness -I think- to the finished building, the panelling scheme clearly expressed, having more to do with transport constraints and footing and connection details than Miesian (or Zumthorian) perfection. We allowed all this to be read in the finished space, not seeking to hide this traces of assembly.

Altogether more problematic was the question of the finished appearance. A regrettable glitch in the construction progress -the auditorium spending the rainy summer holidays without a temporary roof- meant that the unfinished building had -paradoxically- to be restored, each surface painstakingly sanded. This, however, could have been avoided with precise, lock-step sequencing and appropriate improvisation. This situation was perhaps exacerbated by another diplomatic irruption: the G7 summit held in Bavaria in May 2015 had the side-effect of delaying exceptional transport movements (supposedly for security reasons), meaning our tallest panels did not reach the site on schedule.

Another challenge for CLT -as a lightweight structural material- was to achieve the required sound break-out insulation in the context of a quiet woodland neighbourhood with very low background noise levels. Our acousticians Charcoalblue specified resilient hooks and sleeved screws for the connection between the outer insulating panels and the structure itself, arriving at 75 decibels for medium frequencies, the equivalent of a concrete structure. An outer rain screen layer of untreated larch battens -fixed at 45 degreescompleted the standard envelope detail. It should be stated that this outer skin is designed to weather gradually from silvery at the sun-bleached south to a residual beige at the shadowy north. It gives a rather furry aspect to the finished building, catching raking light, smoothing the shadows on the cylinder. I was greatly surprised - and humbled- recently to discover this 45-degree system in use in Japan, dating back to the latticed renji-koushi in the 7th century Houryuuji temple in Nara, I also saw many examples in Shinto and Buddhist temples in Kyoto.

The building’s superstructure and flooring are entirely made -excepting a few pieces of steel and glass- of spruce from Bavaria, larch from the Barents coast and oak from Burgundy: a sort of wooden, pan-european diplomatic force working in concert. The CLT panels were formed and robot-cut in Merk’s factory near Augsburg. (...) 

The building is intended to be radically monomaterial, a body made of wood, resonating, sensed as warm, slightly rough to the touch, as if carved from a single source. Like Shakespeare’s theatres, it was assembled from precisely prefabricated components -in this case bolted and screwed together rather than pegged. It is -at least theoretically- possible to dismantle and move it, although it would be very wasteful in terms of roof membranes and so on.

One of the challenges of the building’s site was the need to keep the building as small as possible. The neighbouring Chateau d’Hardelot is a historic monument dating from the 13th and 19th centuries and the surrounding parkland had to be delisted for our project. Our efforts concentrated on making the volume the tightest possible fit to a precisely defined interior function; this gave the slightly constructivist carve-out of the various asymmetric curved volumes. It was fully intentional not to express the auditorium’s axiality to the outside: the French tradition of siting monumental buildings in parkland is essentially one of drawing straight lines. In our case the building turns its shoulder to the main approach, obliging the visitor to experience the complexities of the wooded site before suddenly turning a corner and discovering the entrance door, which is reached across a lawn.

We introduced one last material to complete the composition. Bamboo is not -strictly speaking- a wood, though it is most often used in construction for framing in a manner similar to wood, albeit with much greater lightness and tensile strength. It can be bundled into the ribs of huge domes by architect Simon Velez, or bent into tensile arches. In France it is not a recognised construction material, in spite of being stronger than steel in tensile strength, weight for weight. We decided to use it nonetheless, albeit not as a structural element: 12 metre high stalks, harvested in Indonesia, are assembled to make a shimmering cage around the building, resolving the existenz-minimum masses previously described into a virtual cylinder resembling Shakespeare’s Globe in ghostly form. The building also vibrates with its context of spindly Horse Chestnut branches casting shadows onto the curved shell.

I have loved conceiving and crafting this building -even though the process has been chaotic, very undiplomatic, and financially ruinous for my practice. I hope that this love - of material, of place, of the building’s users, of the broader context of resources and energy in which it intervenes- will remain as the primary message of the finished building.
