The architect in charge of the new Lonja was Pere Compte, who built the main body of the building – the Trading Hall (or "Sala de Contractació" in Valencian) – in only fifteen years (1483–1498).
Zasnova nove "Llotja" v Valenciji je izhajala iz podobne strukture kot "Lonja" v Palma de Mallorci, ki jo je zgradil arhitekt Guillem Sagrera leta 1448.
