Temporary scaffolding and construction hoardings are excluded; this depicts the permanent architecture.","Source polygons control closed wall levels and all roof plans. Plans sharing a wall interval are unioned before extrusion; source roofs are closed by their mapped gables and supporting wall caps and preserve mapped min_height passages. The narrow Victoria porch is built from its mapped lower plans, not a solid bounding rectangle. Missing roof:shape is interpreted as flat when no rise is mapped. Hips and mansards use documented setback profiles, while the Hall and wings retain actual gabled roofs.","Photo-guided inference: window rows and mullions, cornice courses, parapet crenellation, roof ridge caps, Hall buttresses and rose window, lean Gothic surrounds and small finials. Central drum50-53.5m is bridged inside its mapped upper octagon to make a continuous tower. Fine heraldry, figurative sculpture, inscriptions, flag fabric, trees and interiors are omitted. Both authored LODs retain all principal roof zones and tower silhouettes; low omits mapped ornaments smaller than5m2 below40m, reduces window bays and cornices, and omits buried ground soffits.
