The fit was very comfortable, perhaps too comfortable. Somerset House was designed and built as the intended home of several key institutions in the Georgian civil service. It was the headquarters of the Hawkers and Pedlars Office for example, but also for a spell the Royal Academy. Chambers’ interior layout was decidedly domestic though. Despite its palatial facade facing the Strand, the arrangement effectively was six separate houses, with individual staircases. Although the former director of the Courtauld (and Soviet spy), Anthony Blunt, had long died by the time the Courtauld had moved into the northern wing of the building, an atmosphere of connoisseurship and secrecy clung to the timber clad staircases.

One of the great successes of this conversion is that all the joy of the intimacy is retained, with nearly all of the inconvenience gone. The Courtauld’s unique offering was always the opportunity it gave visitors to see works like Van Gogh’s Self Portrait with Bandaged Ear and Manet’s A Bar at the Folies-Bergère in a cozy setting. It always felt as if you were discovering the work in an attic for the first time, one of the place’s many charms. Still, the circulation, up and down Georgian staircases, was laughably cramped and a trip through the galleries generally ended with the arrival at a locked door and visitors walking back on themselves.

The highly detailed restoration and reworking of the building by Witherford Watson Mann, who was recently shortlisted to reimagine London’s National Gallery, does not totally erase those conditions, but it does provide even greater opportunity for that sense of discovery. There are only a handful of moments where the change to the building is made clear: a new ticket office, for example, where the Medieval gallery once stood on the ground floor. Two new elevators have been added: one to the conservation center in the western side of the wing, the other for gallery visitors. The previously inaccessible cellar, historically used to store coal, has been scooped out to create space for a new shop and a passage that links the west and east portions of the northern wing. To achieve this, the construction team propped up the entire listed building, creating, in a single pour, new concrete columns which allowed the cellar to be opened up. Given that this work is just legible in the way that the concrete has been left separate to the brickwork of the vaults, it seems only fair that the architects permitted themselves one moment of indulgence: a cantilevered concrete stair down to this basement level from the new reception off the main entrance on the first floor.

But the rest of the work one might describe as radically conservative. The new additions are less legible as in other historical work by Witherford Watson Mann, such as the Astley Castle (RIBA Stirling Prize 2013), but then the variety of heritage conditions in each room at The Courtauld prevented the architects from making uniform decisions across the building. Parts have been removed, cleaned, and then replaced. Every door has been taken off its hinges and had integrated access control and fire-proofing added before being re-stained or grained according to its original condition. At the top of the building, the false ceiling that closed out the Great Room gallery has been taken down to reveal the clerestory.

Stephen Witherford, the partner in charge of the project, says, “A project of this nature is a complex metabolism where the big moves are completely enabled and sustained by the thousands of small adjustments–fire safety, access, security, environmental control. Everything is an intervention and everything is a one–off.” Rather than engineered floors, individual floorboards are used throughout, to allow access to the complex services threaded between the over-two-hundred year old joists beneath the floor. Often these joists are arranged at strange angles, meaning that the screws for the boards have to follow them. All the ventilation pipework that once ran vertically in the walls between the flues from the fireplaces has been removed, and it now traverses horizontally across the ceiling and floors, with screens embedded into the ceiling mouldings. Chandeliers have been replaced by more modern lighting and the art is now the focus rather than the interior decoration.

Particularly noticeable is the greater provision of gallery space on the second floor, which was previously legible to the visitor as a layer of locked doors between the entrance and the first gallery spaces they arrived at. Noticeable too are the conversions of attic spaces on the top floor, which not only provide extra hanging space for work that communicates with the Impressionist blockbusters in the adjacent Great Room, but gives that space a sense of culminating the visitor experience.

The shift in experience is achieved accumulatively: the several major, and the many minor, interventions contributing to a greater sense of space, bringing the artwork to the foreground. In fact, it is amazing how different the experience of extra space is, given that there is only 43 additional linear feet for hanging paintings. What has changed though is the range of gallery sizes and their ability to be opened and closed in relation to each other, allowing great variety to curators and their audiences. This increase in flexibility for exhibiting also has the benefit of making the unique relationships between the collection, the galleries, and the institute more porous, though perhaps not as much as the Courtauld’s management and the architects would have liked.

However, the results mean that the gallery can, if anything, double down on its previous strengths. Given the range of its collection, it is now uniquely placed to present far more intimate, assiduously curated shows than before. The change has done it good.
