| 3 | Generate complete urban masterplans from site understanding through spatial |
| 4 | structure, land use distribution, street network, block layout, density |
| 5 | strategy, phasing plan, and implementation framework. This skill orchestrates |
| 6 | multiple specialized sub-skills into a coherent design process that produces |
| 7 | a fully resolved masterplan at any scale from a single city block to an |
| 8 | entire new district or town extension. |

| 12 | ## 1. Masterplan Design Process |
| 13 | |
| 14 | The masterplan design process follows eight sequential phases. Each phase |
| 15 | builds upon the outputs of the previous phase. Do not skip phases; mark any |
| 16 | phase "Deferred" with justification if the user has not provided sufficient |
| 17 | input. Cross-skill invocations are indicated with the `-->` symbol. |

| 19 | ### Phase Checklist |
| 20 | |
| 21 | ``` |
| 22 | Phase 1: Site Understanding |
| 23 | [ ] Site analysis complete or provided by user |
| 24 | [ ] Constraints and opportunities mapped |
| 25 | [ ] Key connections to surrounding context identified |
| 26 | --> invoke site-analysis if not already done |
| 27 | |
| 28 | Phase 2: Vision and Program Definition |
| 29 | [ ] Design vision statement drafted (1 paragraph) |
| 30 | [ ] Target population and household count established |
| 31 | [ ] Total GFA by use type calculated |
| 32 | [ ] Character precedents identified (3-5 reference projects) |
| 33 | [ ] Sustainability and resilience targets set |
| 34 | --> invoke precedent-study if user requests comparable projects |
| 35 | |
| 36 | Phase 3: Structuring Framework |
| 37 | [ ] Movement framework established (primary routes, transit spine) |
| 38 | [ ] Green-blue framework established (parks, corridors, water) |
| 39 | [ ] Built form framework established (centers, edges, density gradient) |
| 40 | [ ] Transect zones defined and mapped (T1-T6 as applicable) |
| 41 | [ ] Framework tested against site constraints |
| 42 | |
| 43 | Phase 4: Street Network Design |
| 44 | [ ] Street hierarchy defined (arterial, collector, local, shared) |
| 45 | [ ] Cross-sections assigned to each street type |
| 46 | [ ] Key intersections and public transport stops located |
| 47 | [ ] Block structure generated from street network |
| 48 | --> invoke street-design for hierarchy and cross-sections |
| 49 | |
| 50 | Phase 5: Block and Parcel Layout |
| 51 | [ ] Block typologies selected for each Transect zone |
| 52 | [ ] Block dimensions and perimeters verified against standards |
| 53 | [ ] Parcel subdivision logic applied |
| 54 | [ ] Building footprint envelopes tested for feasibility |
| 55 | --> invoke block-and-density for typology selection and optimization |
| 56 | |
| 57 | Phase 6: Land Use and Program Distribution |
| 58 | [ ] Land use zones assigned to each block or parcel |
| 59 | [ ] Use mix percentages verified against vision targets |
| 60 | [ ] Anchor uses located (schools, community centers, retail cores) |
| 61 | [ ] Ground-floor activation strategy defined for key streets |
| 62 | --> invoke mixed-use-programming for use mix and allocation |
| 63 | |
| 64 | Phase 7: Public Space Network |
| 65 | [ ] Neighborhood park(s) sized and located (within 500 m of all residents) |
| 66 | [ ] Central plaza or civic space defined |
| 67 | [ ] Pocket parks and play spaces distributed |
| 68 | [ ] Greenways and pedestrian corridors connected |
| 69 | [ ] Public space typology and character described |
| 70 | --> invoke public-space-design for parks, plazas, civic spaces |
| 71 | |
| 72 | Phase 8: Phasing and Implementation Strategy |
| 73 | [ ] Development phased into 3-5 stages |
| 74 | [ ] Infrastructure sequencing plan completed |
| 75 | [ ] Catalyst projects identified for Phase 1 |
| 76 | [ ] Interim use strategy for undeveloped parcels defined |
| 77 | [ ] Governance and delivery mechanism outlined |
| 78 | ``` |

| 82 | ## 2. Structuring Framework Methodology |
| 83 | |
| 84 | The structuring framework is the spatial DNA of the masterplan. It establishes |
| 85 | the primary organizing systems before any building is placed. Three overlapping |
| 86 | frameworks -- movement, green-blue, and built form -- are developed in parallel |
| 87 | and then overlaid to create the composite spatial structure. |
| 88 | |
| 89 | ### Movement Framework |
| 90 | |
| 91 | Establish the hierarchy of movement from regional connections down to the |
| 92 | individual street. |
| 93 | |
| 94 | 1. **Regional connections**: identify all points where the site connects to the |
| 95 | surrounding road network, transit system, and cycling/pedestrian paths. These |
| 96 | are the fixed anchors of the movement framework. |
| 97 | 2. **Primary routes**: draw the main streets that connect the anchor points |
| 98 | across the site. These carry the highest traffic volumes, public transit |
| 99 | lines, and utility trunk infrastructure. Typical right-of-way: 24-36 m. |
