Visitors to the new Lasdun exhibition at the Royal College of Physicians will envy the relationship between client and architect

In the late fifties, Denys Lasdun found himself sitting in a classically detailed, oak-panelled room dating back to the 17th century being interviewed for the position of architect. The commission was a new college for one of the medical profession鈥檚 oldest and most respected organisations. When asked if he would design a classical building, he resolutely replied: 鈥淣o!鈥

Instead, he said he would deliver 鈥溾 modern building with grace, elegance and charm鈥. That was just what Robert Platt, the president of the Royal College of Physicians, wanted to hear. Lasdun later described Platt as 鈥渁 visionary, who knew he had to build for tomorrow鈥 and so began the process of designing what is undoubtedly one of the best modern buildings in the heart of neo-classical London.

For the thousands of visitors the building receives every year, the exhibition The Anatomy of a 好色先生TV: Denys Lasdun and the Royal College of Physicians will reveal how closely Lasdun worked with his client. From the archives of the college are letters between architect and client as well as Lasdun鈥檚 own notes (he was meticulous in taking these) about recording and overcoming the reservations that were expressed at the time. These are the most intriguing parts of the exhibition as it reveals a very personal process of how this building evolved. Compare and contrast, for example, the wonderful picture of a pile of discarded models in a corner of Lasdun鈥檚 office with OMA鈥檚 meticulously archived blue foam models.

The best artefact in the exhibition is the building itself. Visitors can explore how the building relates to the adjacent Nash Terraces, to Regent鈥檚 Park and to Albany Street at the rear

The best artefact in the exhibition is the building itself. With references to Villa Savoye and the modernist canon, visitors can explore how the building relates to the adjacent Nash Terraces, to Regent鈥檚 Park and to Albany Street at the rear. The handmade porcelain mosaic tiles that clad both the exterior and interior were carefully specified to match the stucco of adjacent buildings. Just one example of how well thought out this building is.

With regard to initiation into the college, Lasdun clearly understood the importance of ritual and ceremony in that process. It is the reason why the room in which he was interviewed, known as the Censor鈥檚 Room, was transplanted in its totality from the previous college to become the heart of the new building. The anatomical analogy continues with the main processional circulation stair leading to the Dorchester Library where the portrait of William Harvey (who was the first to describe how blood is circulated around the body by the heart) takes pride of place.

Models of some of Lasdun鈥檚 other buildings are also on display including the first abandoned scheme for the National Theatre but this exhibition is primarily about understanding the building that houses it and the person that created it. When looking back, Lasdun expressed his gratitude to the college for its 鈥渕onumental act of faith鈥 in commissioning him to design such a modern building. It is appropriate that one of his last buildings was an addition to the college completed in 1998.

The exhibition coincides with the 50th anniversary of the opening of the building and the 100th anniversary of Denys Lasdun鈥檚 birth. It runs until February 13 next year and there are tours of the building on September 21, arranged as part of Open House London.
