Site To Building

This guide shows the intended authoring sequence for ArchAI.

1. Plot Or Import The Parcel

site main:
  parcels:
    parcel pcl_001:
      coordinate_system project_mm
      boundary:
        edge front: (0, 0) -> (42000, 0) tags [frontage]
        edge east:  (42000, 0) -> (39000, 28000)
        edge rear:  (39000, 28000) -> (4000, 31000)
        edge west:  (4000, 31000) -> (0, 0)

Creates:

site.main.parcels.pcl_001
site.main.parcels.pcl_001.boundary.edges.front

2. Add Planning Constraints

constraints:
  setbacks:
    front:
      from boundary.edges.front
      distance 5000mm
    side:
      from [boundary.edges.east, boundary.edges.west]
      distance 3500mm
  height_limit primary:
    max 18000mm

Creates:

site.main.parcels.pcl_001.constraints.setbacks.front
site.main.parcels.pcl_001.constraints.height_limit.primary

3. Compute The Envelope

envelopes:
  primary:
    parcel parcels.pcl_001
    derive_from parcels.pcl_001.constraints

Creates:

site.main.envelopes.primary

4. Generate A Building Option

buildings:
  building b_001:
    parcel site.main.parcels.pcl_001
    envelope site.main.envelopes.primary
    use residential
    target_gfa 4200sqm

    generation:
      floor_to_floor 3100mm
      max_floorplate_depth 14500mm

    systems:
      core main:
        strategy central
        stairs 2
        elevators 2

Creates:

buildings.b_001
buildings.b_001.systems.core.main

5. Evaluate And Repair

The evaluator should return path-rich findings.
