A monumental edifice replete with rhythmic louvres, clean lines, and angled massing clad in Portland stone, The Marshall Building at the London School of Economics and Political Science establishes a new presence for the university’s central London campus, bordering the lawns of Lincoln’s Inn Fields to the north. Designed by Dublin-based firm Grafton Architects led by Pritzker Prize-winning architects Yvonne Farrell and Shelley McNamara, the institutional building’s recent opening in the United Kingdom is the culmination of a six-year long process that commenced with the selection of the practice’s proposal as the winning entry of an architectural competition held in 2016. Now, fully realised, the building straddles a delicate urban domain of contrasting environments that include the London School of Economics campus to the south, and verdant open fields to its north.

Due to its skirting the edges of these two zones, the structure’s design has been adapted to the geometries of the site, maintaining a somewhat unified expression that continues the visual identity of the institutional architectural setting it is nestled within. Embodying Grafton Architects’ penchant for ‘weighty,’ sculptural buildings that honour the spirit of their context and exude a subtle yet firm monumentality, the lower section of the structure’s front is a datum clad in Portland stone, punctured by angular voids looking on to Lincoln’s Inn Fields. This edifice is more open to the sky, employing a system of screens and fins to shade the western side of the building. Conversely, the southern façade design balances entrances, screened terraces, solid gables, and a regular grid of windows with shading elements to create a cohesive visual character and visually connect interior areas to Sheffield Street and John Watkins Plaza within the campus.

Containing 18,000 sqm of functional space, the building houses lecture theatres, informal study spaces, academic offices, music rehearsal and arts facilities, squash courts, and a 20m x 35m sports hall in its spatial programming. To accommodate this diversity of functions and the ensuing structural complexity that stemmed from it, the design team devised a tree-like system of beams and columns that address the issue of transferring loads from the smaller spans on the upper levels to increasingly large ones on the ground floor and first floor. In essence, this configuration makes use of outward spreading diagonal branches that direct gravitational forces to the ground and create a stunning example of biomorphic concrete architecture in the process.

On this note, the materiality of concrete defines much of the interior design, shaped by the tapering canopies of the branching columns. This is especially visible in the Great Hall on the ground floor. Grafton Architects shares in a press statement, “Under the tree branches at the ground floor a new social space for the university is created - ‘the Great Hall’. Conceived as a covered piazza with a sloping terrazzo floor it allows level access at all three entrances.” A spiralling concrete staircase within the plan acts as a sculptural focal point for the space and is the main avenue for vertical circulation.

On the upper levels, lecture halls and classrooms have been placed around an open student commons, which has been described by the architects as a grand ‘piano nobile.’ The gentle curvature of the walls here allows them to weave in and around members of the branching structural system. Finished with sound absorbent timber panelling, these surfaces also integrate benches and desks that facilitate informal study. As a means to maximise natural lighting and ventilation, the layout of the academic offices on the topmost floors rotates the geometry of the site, with three wings that diminish in height from nine storeys at the southern face, to seven on the side overlooking Lincoln’s Inn Fields. Fissures between the blocks form terraces and gardens that act as islands of landscape design amid the concrete and stone forest of the interior.

“A stepped atrium skewers these different worlds together, drawing zenithal light deep into the plan. Stairs and small meeting rooms weave in and out this space, creating opportunities for overlap and exchange,” notes the design team. Narrow concrete fins and acoustic insert panels mediate sound transfer between the levels of this space, which has been conceptualised and implemented in the vein of an external court. Sports facilities in the complex are connected via an external stair in the Great Hall, which descends into the building’s light well and also leads to the bicycle parking zone towards the north of the site. The large volumes of the sports hall and squash court on the lower ground floor are also visually interlinked to the remainder of the layout through the inclusion of this light well.

Contemplating their unique accomplishment with this latest addition to the historic campus of the London School of Economics and Political Science, Grafton Architects states: “In summary, this building houses four different worlds stacked vertically and rising from below ground to the sky. The world of sport, civic space, teaching, and research are all volumetrically and structurally interwoven. This is a microcosm of the city, with a multiplicity of uses forming a rich and nourishing environment for university life.”
