Here are the first official photographs of the completed 2011 Serpentine Gallery Pavilion, which was unveiled today by Swiss architect Peter Zumthor. Update: this project is included in Dezeen Book of Ideas, which is on sale now for £12.

Update 28/06/11: watch Zumthor talking about the pavilion and his work in our interview on Dezeen Screen

A planted garden by Dutch designer Piet Oudolf is enclosed at the heart of the black-painted pavilion, filled with flowers and shrubs.

This inner garden is surrounded by a blue bench under a canopy that projects inwards from the walls.

The pavilion is a timber framed structure covered in gauze and painted over with a black adhesive.

A narrow corridor circulates the perimeter of the building between the facade and the garden.

The pavilion opens to the public this Friday the 1 July and remains open until 16 October.

It is the first building to be completed in the UK by Zumthor and will be followed next year by The Secular Retreat in Devon for Alain de Botton’s Living Architecture project.

Serpentine Gallery Pavilion 2011
Designed by Peter Zumthor

The Serpentine Gallery Pavilion 2011 is designed by world-renowned Swiss architect Peter Zumthor. This year’s Pavilion is the 11th commission in the Gallery’s annual series, the world’s first and most ambitious architectural programme of its kind. It is the architect’s first completed building in the UK and includes a specially created garden by the influential Dutch designer Piet Oudolf.

At the heart of Peter Zumthor’s Pavilion is a garden that the architect hopes will inspire visitors to become observers. Zumthor says his design ‘aims to help its audience take the time to relax, to observe and then, perhaps, start to talk again - maybe not.’ The design emphasises the role the senses and emotions play in our experience of architecture. With a refined selection of materials Zumthor creates contemplative spaces that evoke the spiritual dimension of our physical environment. As always, Zumthor’s aesthetic goal is to customise the building precisely to its purpose as a physical body and an object of emotional experience. Zumthor has stated that ‘the concept for this year’s Pavilion is the hortus conclusus, a contemplative room, a garden within a garden. The building acts as a stage, a backdrop for the interior garden of flowers and light. Through blackness and shadow one enters the building from the lawn and begins the transition into the central garden, a place abstracted from the world of noise and traffic and the smells of London – an interior space within which to sit, to walk, to observe the flowers. This experience will be intense and memorable, as will the materials themselves – full of memory and time.’

Materials have always played an evocative as well as an essential role in the buildings designed by Zumthor. The 2011 Pavilion is constructed of a lightweight timber frame wrapped with scrim and coated with a black Idenden over scrim. Exterior and interior walls with staggered doorways offer multiple paths for visitors to follow, gently guiding them to a central, hidden inner garden. The covered walkways and seating surrounding this central space create a serene, contemplative environment from which visitors look onto the richly planted sunlit garden, the heart and focus of the building.

With this Pavilion, as with previous structures such as the famous Thermal Baths at Vals, Switzerland, or the Bruder Klaus Chapel in Mechernich, Germany, Zumthor has emphasised the sensory and spiritual aspects of the architectural experience, from the precise yet simple composition and ‘presence’ of the materials, to the handling of scale and the effect of light. Piet Oudolf is a prominent garden designer and a leading figure of the New Perennial planting movement. His award-winning designs emphasise the natural architecture of plants, using expressive drifts of grasses and herbaceous perennials to create gardens that evolve in form throughout the lives of the plants. These are chosen for their structure, form, texture and colour, showcasing many different varieties in his compositions. Oudolf has pioneered an approach to gardening that embraces the full life-cycle of plants, delighting in their beauty throughout the seasons.

Piet Oudolf said: “I am very pleased to be collaborating with Peter Zumthor and the Serpentine Gallery on this year’s Pavilion and to be part of this exciting project. My work aims to bring nature back into human surroundings and this Pavilion provides the perfect opportunity for people to reflect and relax in a contemplative garden away from the busy metropolis.”

The Serpentine’s Pavilion commission, conceived in 2000 by Gallery Director Julia PeytonJones, has become an international site for architectural experimentation and follows a decade of Pavilions by some of the world’s greatest architects. Each Pavilion is sited on the Gallery’s lawn for three months and the immediacy of the commission – a maximum of six months from invitation to completion – provides a unique model worldwide.

Julia Peyton-Jones, Director, and Hans Ulrich Obrist, Co-Director, Serpentine Gallery, said: “It is an honour and a great joy to be working with Peter Zumthor on the 11th Serpentine Gallery Pavilion. The commission allows us to connect with the best architects in the world and each year is an exciting and completely new experience. Zumthor’s plans will realise an exquisite space for the public to enjoy throughout the summer.”

Zumthor’s Serpentine Gallery Pavilion will operate as a public space and as a venue for Park Nights, the Gallery’s high-profile programme of public talks and events. Park Nights will culminate in the annual Serpentine Gallery Marathon in October, now in its sixth year. In 2006 the Park Nights programme included the renowned 24-hour Serpentine Gallery Interview Marathon, convened by Hans Ulrich Obrist and architect Rem Koolhaas; in 2007, the Serpentine Gallery Experiment Marathon presented by artist Olafur Eliasson and Hans Ulrich Obrist; in 2008, Obrist led over 60 participants in the Serpentine Gallery Manifesto Marathon. These were followed in 2009 by the Serpentine Gallery Poetry Marathon and in 2010 by the Serpentine Gallery Map Marathon.
