Lemoine lives and works between France and Italy. Since 2005 she has been working in collaboration with her husband Ila Bêka with whom she founded the research and creation platform Bêka&Partners.

Presented by The New York Times as “cult figures in the European architecture world”, Lemoine and Bêka mainly focus their research on experimenting new narrative and cinematographic forms in relation to contemporary architecture.
Koolhaas Houselife, the first film she co-directed with Bêka in 2008, has been acclaimed by the international critique as “the architectural cult movie”. They self-financed the film in order to assure creative freedom.

Following the success of Koolhaus Houselife, Bêka and Lemoine shot the four other films that would make up their Living Architectures series. This series, which comprises Koolhaus Houselife; Pomerol, Herzog & de Meuron; Xmas Meier; Gehry’s Vertigo; and Inside Piano, follows the mundane realities of maintaining buildings by renowned architects, including Rem Koolhaas (the Bordeaux house), Frank Gehry (the Bilbao Guggenheim), and Auguste Perret.

Her films have been selected and awarded in some important international film festivals such as CPH:DOX, Chicago International Film Festival, DocAviv, Torino Film Festival, FIFA, etc.
She has been invited to lecture and present her films in many international cultural institutions and prestigious universities such as Venice Biennale (2008, 2010, 2014), MoMA (New York), Metropolitan Museum of Art (New-York), Centre Pompidou (Paris), Palais de Tokyo (Paris), Barbican Art Gallery (London), Canadian Centre for Architecture (Montréal), NAi (Rotterdam, NL), MAXXI (Rome), Harvard GSD, Architectural Association School of Architecture (London), Mextropoli (Mexico).

Her films are part of important art collections, the CNAP have acquired in 2014 a copy of Koolhaas Houselife and in 2015 a copy of the video installation La Maddalena for the French national collections. The video work Spiriti has been commissioned by Fondazione Prada for their private collection.

In 2016 Ila Bêka and Louise Lemoine’s complete work (16 films) has been acquired by MoMA, Museum of Modern Art in New York.
