This is a directional sign for a housing development or estate called 'บ้านกาญจน์กนก' (Baan Kanchanok). 'บ้าน' (bâan) means 'house/home' and is commonly used in Thai housing project names. 'กาญจน์' (kaan) derives from 'กาญจนา' meaning 'gold' (from Pali/Sanskrit), and 'กนก' (gà-nók) also means 'gold' — so the name is a poetic double reference to gold.

The number 21 likely refers to a phase or lot number.
