Building

buildings/<id>.ron — OURS; building TYPES for worldgen to instantiate.

Field	Type	Required	Description
build_cost	[string, uint32][]	required	Future-construction data with NO consumer yet (`data/README.md`).
furnishings	[string, uint32][]	default []	The type-appropriate genesis furnishing: `(goods/ id, count)` a venue of this type is dressed with — the good must carry a `furnishing:` block. Empty = the default domestic dressing (the `house` type's list).
id	string	required	Authored id.
name	string	required	Authored name.
requires	string[]	required	Terrain tags, ALL required (a conjunction); `[]` = anywhere.
rooms	RoomSpec[]	optional	The building's ROOM PROGRAM (designer-ruled moddable): the roles its floor plan claims, in claim order (biggest room first). Role names are OPEN vocabulary — the engine branches only on the mechanical flags, so a modded type may declare any rooms it likes. Empty = the default domestic program (the `house` type's).
source	Source	required	Authored source.
storage	boolean	required	True = the venue can stockpile goods.
storeys	integer	optional	How many storeys the type raises (1..=3, validated); the engine still gates upper floors on footprint mass. Default 1.

Nested shapes

Every shape Building closes over, so this page stands alone.

RoomSpec

One entry of a building's room program: the role NAME is open modder vocabulary (the narrator's word, the furnishing router's address); the FLAGS are what the engine's code branches on.

Field	Type	Required	Description
public	boolean	default false	The PUBLIC room: claims the entrance, and opens to every room it touches (the taproom rule). Exactly one per program (validated).
role	string	required	The role's name — free vocabulary ("taproom", "laboratory"…): the address a furnishing's `rooms:` list routes to.
upper	boolean	default false	May this role live on an upper floor? Ground-only when false.

Source

Every file's top-level value carries source.

`Srd51`

SRD 5.1 — retained nonconflicting catalogue material.

`Srd52`

SRD 5.2.1 — the 2024-revision System Reference Document, the same CC-BY-4.0 grant as 5.1 and the current rules chassis. Its files carry the .srd52.ron suffix so provenance reads off the path; see data/README.md for which document rules a given value.
