## Functions
| assert_compile (HZB_END==5)
static HouseID | GetTranslatedHouseID (HouseID hid)
| Do HouseID translation for NewGRFs.

## Variables
static const byte | TOWN_HOUSE_COMPLETED = 3
| Simple value that indicates the house has reached the final stage of construction.
static const HouseID | NUM_HOUSES_PER_GRF = 255
| Number of supported houses per NewGRF; limited to 255 to allow extending Action3 with an extended byte later on.
static const uint | HOUSE_NO_CLASS = 0
static const HouseID | NEW_HOUSE_OFFSET = 110
| Offset for new houses.
static const HouseID | NUM_HOUSES = 512
| Total number of houses.
static const HouseID | INVALID_HOUSE_ID = 0xFFFF
static const uint | HOUSE_CLASS_MAX = NUM_HOUSES - NEW_HOUSE_OFFSET + 1
| There can only be as many classes as there are new houses, plus one for NO_CLASS, as the original houses don't have classes.

## Enumeration Type Documentation

enum HouseExtraFlags

Enumerator:

  BUILDING_IS_HISTORICAL | this house will only appear during town generation in random games, thus the historical
  BUILDING_IS_PROTECTED | towns and AI will not remove this house, while human players will be able to
  SYNCHRONISED_CALLBACK_1B | synchronized callback 1B will be performed, on multi tile houses
  CALLBACK_1A_RANDOM_BITS | callback 1A needs random bits

Definition at line 88 of file house.h.

enum HouseZones

Enumerator:

  HZ_NOZNS | Bit Value Meaning. 0 This is just to get rid of zeros, meaning none
  HZ_ZON1 | 0..4 1,2,4,8,10 which town zones the building can be built in, Zone1 been the further suburb
  HZ_ZON5 | center of town
  HZ_ZONALL | 1F This is just to englobe all above types at once
  HZ_SUBARTC_ABOVE | 11 800 can appear in sub-arctic climate above the snow line
  HZ_TEMP | 12 1000 can appear in temperate climate
  HZ_SUBARTC_BELOW | 13 2000 can appear in sub-arctic climate below the snow line
  HZ_SUBTROPIC | 14 4000 can appear in subtropical climate
  HZ_TOYLND | 15 8000 can appear in toyland climate
  HZ_CLIMALL | Bitmask of all climate bits.
