"Foundations" is a song co-written by English singer-songwriter Kate Nash for her debut album, Made of Bricks (2007).

Colourful everyday items such as toothbrushes, shoes, socks and toys (one of which appears to be a Yellow Power Ranger) are prominent.

It follows the song closely, and is made up of several main scenes; Nash playing a card game, turning in bed, eating lemons ("you've said I must eat so many lemons, because I am so bitter"), sitting on a staircase, arm wrestling, decorating a cake and sitting in her lounge, but is not happy living with her boyfriend.

[3] In August 2007, The Guardian gave the song a mixed review, citing its strong comparisons to Lily Allen, but praised the "indelible chorus".

[4] In September 2007, Pitchfork Media gave a positive review of the song, citing Nash's "gift for communicating confusing romance with a keen eye for detail and scene-stealing turns of phrase".
