A broad smile spreads over Steve Tompkins鈥� face as he describes working with artist Clem Crosby on the new fa莽ade of the Young Vic theatre in south London. 鈥淎rtists add a different dimension to the process,鈥� the director of Haworth Tompkins Architects says. 鈥淭hey aren鈥檛 conditioned by education, regulations and protocol; all the things that make a standard project standard. But there has to be great trust on both sides. If that鈥檚 lacking, then the whole process can go badly wrong.鈥�

Crosby, an abstract artist who is renowned for his works of oil on Formica, clearly also enjoyed the design process. 鈥淚 was involved in the design and present at meetings at the practice. I felt I had licence to throw in ideas,鈥� he says. 鈥淭hey may or may not have been seen as naive or overly optimistic but, because I stood slightly apart from the architectural process, I think they were valid. I came at it from left-field.鈥�

His contribution to the complete reworking of the Young Vic theatre has given it its most striking feature: a vast fa莽ade lined with 180 of Crosby鈥檚 monochrome paintings, each 2.5 m by 1.2 m. These sit side-by-side, giving the rejuvenated four-storey building a vivid cadmium-yellow front.

The collaboration between architect and artist came about at Tompkins鈥� request. Haworth Tompkins has worked with artists before, and when one of London鈥檚 most avant-garde theatres signed up for its services, not much hard work was needed to persuade the new client that cross-discipline working would be a good idea.

The brief for the project was to create a completely new fa莽ade for the theatre, incorporating a portion of the original architecture into it and building some new areas from scratch. The extra layer of space provided between the fa莽ade and the original interior would deliver more circulation space for theatre-goers 鈥� as well as creating a good place to locate technical services. Much of the 1970s building was to be demolished to make way for the new; only the main auditorium and the original hub of the building 鈥� once a butcher鈥檚 shop 鈥� would be spared.

Haworth Tompkins decided the fa莽ade should consist of four distinct elements. Two new studios, or rehearsal spaces, clad in brick would provide 鈥渂ookends鈥�. Between them, a new, fully glazed bar and foyer space would be created, which would include an old butcher鈥檚 shop already on the site. The original blockwork auditorium was not extended outwards, but upwards 鈥� more height was gained by raising the roof.

To support the new fa莽ade, a framework of large steel beams was constructed that transfers all of the weight to corner columns set on pile foundations. The internal wall of the frontage is clad with 150 mm-thick Tradis timber wall panels, which are filled with blown cellulose insulation. Crosby鈥檚 paintings are attached to horizontal and vertical rails, with the space between the rails and the timber resulting in a ventilation gap.

Each of the painted panels on the fa莽ade is unique. 鈥淓very panel can be read as a painting in its own right,鈥� Crosby says. They are made of mineral fibreboard and covered with a cellulose-based paint. Primed in black and then over-painted in the yellow, the panels have also been sprayed with a weatherproof lacquer. 鈥淭hey were produced in batches of 15 to 20,鈥� Crosby explains, 鈥渁nd then sent away to be stored and not seen again until they were installed. When they were delivered to site, I instructed that they were to be taken from the boxes and installed randomly in order that similarities or differences in the way I had applied the paint on particular days would not overtly influence any part of the larger work.鈥�

Stroke of genius

In the daytime, the yellow paintings are subdued behind a silver-grey mesh 鈥� an external aluminium rain screen that is like a scaled-up version of Expamet mesh. This is held away from the paintings with 317 mm stand-off brackets, and is angled downwards so that the rain runs off it. But it is at night that the fa莽ade quite literally shows its true colours. DHA was the lighting consultant on the project, and low-energy lighting 鈥� a linear projector 030 from Sill Lighting was used 鈥� fixed at low

We wanted to link into the community, and not create a detached culture palace

level between the mesh and paintings reveal the true poetry of the fa莽ade. The light bounces off the mesh and reflects onto the paintings, emphasising their vibrancy, tones and textures 鈥� even brushstrokes.

This dual identity is what the architect strove for in its design. Tompkins says: 鈥淏y day, the theatre is essentially a light industrial unit: the people inside carry out duties akin to maintenance work and so the silver-grey mesh reflects that. Then, at night, the fa莽ade is illuminated, coming to life as the performers take to the stage. Our fa莽ade is a mirror of the life inside the theatre: it stresses its use and creates a unique identity within the varied streetscape.鈥�

Haworth Tompkins was always keen for the design to meld with its surroundings. 鈥淚t was, in part, the richness of the street in which the theatre sits that drew us to work with Clem in the first place,鈥� says Tompkins. 鈥淭he semiotic of the building was tremendously important in the context of the street. The heterogeneous scale of the place is rooted in the community and we wanted to link into that, rather than creating some detached culture palace.鈥�

The project is about function as well as form. The fa莽ade is designed to be inexpensive and yet hardworking, and it also acts as a passive internal temperature regulator. 鈥淭he downward slant of the outer mesh provides good solar shading to all elevations,鈥� says project architect Roger Watts, 鈥渨hile the insulated Tradis panels stabilise the temperature internally far better than the old blockwork walls could do alone. These panels also cut out thermal bridging, as we have been able to fix the cladding rails directly to them rather than through to a structural wall.鈥�

Working with cladding consultant Montresor Partnership, the architect was able to design the whole multi-layered skin for a relatively low cost, while ensuring that it more than conformed to 黑洞社区 Regulations. The Young Vic cost 拢2100/m2 to build; about 拢900 m2 cheaper than any theatre built in the last decade.

鈥淚 know people will focus on the fa莽ade鈥檚 aesthetic,鈥� says Tompkins, 鈥渂ut it must not be seen as an isolated entity. This is where architects fall down; they see the fa莽ade as an opportunity for a photo call. Experimentation is carried out for the sake of it, rather than to realise a functional ideal.鈥�

Design alchemy

Unlike other arresting modern fa莽ades (from Birmingham鈥檚 frivolous Selfridges to south London鈥檚 unbecoming Imax cinema) this exterior works on all levels as part of an energy-conscious building 鈥� a goal, says Tompkins, that 鈥渁ll architects should be trying to achieve on every building they design鈥�.

But despite the concern for functionality, Tompkins admits there was a certain alchemy behind the design process. 鈥淵ou can鈥檛 write a brief for what we鈥檝e achieved here,鈥� he says. 鈥淵ou have to set events in motion and then let go fully, trusting in everyone, to get the best out of each of the performers involved.鈥�

Crosby nods and grins, saying: 鈥淪teve鈥檚 right, it is all about mutual trust. I just wish all these builders would stop calling my paintings cladding panels!鈥�
