The upper floor of town houses had a number of important functions, such as bedrooms, storerooms and dining rooms. This variety of functions is a characteristic shared by houses in both societies. An interesting distinction appears when method of construction is considered. Town houses in Greece were strongly affected by city planning that regulated that all rooms had to face south. On the other hand, town houses in lower and middle class housing in Pompeii show much less evidence of planning and an upper floor was often added at a later date.
