Architect Smiljan Radi膰鈥檚 design is perhaps one of the most whimsical Serpentine Pavilion ever commissioned

In the age of 4D and 5D digital visualisations, thankfully some architects are still obsessed with the ancient art of physical model-making. Should they wish, architects and designers like Peter Zumthor and Thomas Heatherwick could summon Soane Museum-esque vaults of models and maquettes and Frank Gehry is famously able to craft the most futuristic architectural forms from infinite iterations of one of this most traditional physical design processes.

This year鈥檚 Serpentine Pavilion in Kensington Gardens is also indebted to the art of model-making. But while Gehry鈥檚 architecture in its finished form largely abandons the crude accretive process from which it was generated (or at least tries to) in concept, execution and form, this year鈥檚 Serpentine Pavilion is every inch an architectural model writ large.

Chilean architect Smiljan Radi膰 confirms as much when he announces his general approach to architecture and that which informed his work on this year鈥檚 pavilion: 鈥淚 don鈥檛 create forms, I collect shapes.鈥

Consequently, this year鈥檚 pavilion offers one of the most esoteric examples yet of a coveted architectural programme, now in its 14th year, famed for its avant garde experimentalism. On first impressions, particularly from afar, the pavilion appears to resemble a giant, prehistoric boulder teetering precariously on rune-like stones, all of which nestle with splendid incongruity, as all Serpentine Pavilions do, amid the verdant green landscape of Kensington Gardens, Hyde Park and the prim classical contours of the Serpentine Gallery right next door.

Closer inspection reveals otherwise. The boulder is actually a hollow, translucent, fibre-glass circular tube containing a raised timber-decked interior space which offers, by means of large openings sliced into the envelope and at one stage an enigmatically projecting square portal, luscious views out towards the park.

Visitors are also able to wander within the submerged undercroft beneath the pavilion, contemplating at close range the 120 tonnes of rock that support it and looking upwards into the hollowed opening in the middle of the fibre-glass ring above.

When you look at a folly you have to stop rationalising. Don鈥檛 think too much, just accept it. It鈥檚 about being alone with your environment; it鈥檚 a very personal relationship

Smiljan Radi膰

Radi膰 speaks of his determination to create an object that retains the 鈥渟trength and crudity鈥 of the 鈥渕asking tape and papier-mache models鈥 from which the pavilion鈥檚 bulbous form was derived. This is very much in evidence in the fibre-glass envelope of the pavilion whose haphazard joints and junctions erupt in bright sunlight into a diffuse patina every bit as intricate as veins across human skin.

But 鈥渟trength and crudity鈥 is not the only contrast on show here. Architects adore juxtaposition and history shows that those commissioned to produce Serpentine Pavilions, from Nouvel鈥檚 鈥渞ed vs green鈥 to Zumthor鈥檚 鈥渙pen parkland vs secret garden鈥, are particularly susceptible to the 鈥渓ure of the opposite鈥.

Radi膰 proves to be no different and his pavilion is charged with all manner of similarly playful tensions. Opacity vs transparency, solid vs light, strong vs fragile and inside vs outside are just some of preoccupations addressed in this year鈥檚 commission.

But, like model-making, the most intriguing of these clashes is centred on a far more traditional architectural idea, the folly. To an extent, all Serpentine Pavilions, with their temporary lifespans and flamboyantly contrived concepts, are follies. Historically, this has always been an appropriate response to what is essentially an 18th century English park context forged by a Picturesque Movement that idolised the folly.  

But Radi膰 embellishes his pavilion鈥檚 folly credentials by claiming that it is partially inspired by The Selfish Giant, Oscar Wilde鈥檚 haunting paean to the redemptive power of a garden landscape that ultimately promotes love and understanding.

Moreover, Radi膰 also reveals himself to be particularly enthralled by the romantic, transformative power of follies to generate atmosphere and change our relationship with our surroundings and ourselves. 鈥淲hen you look at a folly you have to stop rationalising. Don鈥檛 think too much, just accept it. It鈥檚 about being alone with your environment; it鈥檚 a very personal relationship.鈥

Whether all who visit the pavilion this summer will be struck by such a reckoning is open to question. What isn鈥檛 is that they will invariably encounter one of the most whimsical and enigmatic creations the Serpentine Pavilion programme has ever commissioned.
