Source: Crest 2600 (CRS-2600) — catalog envelope massing, site-feet. · 2 buildings · 4,938 sf footprint · 22 rooms · 29 walls

Design geometry in site-feet — no drawing calibration applies; values are the scheme's own.

Schematic envelope massing generated from the catalog plan's box dimensions (54 ft × 78 ft × 2 stories, 3-car front-load garage) — envelope massing with a designed interior: the interior is a DESIGNED wall-graph layout (22 rooms on story 1; upper stories keep the massing), and a schematic roof style (gable, 4 ft rise) is derived from the footprint (not a designed roof). Heights are declared at 10.5 ft/story.

Schematic envelope massing generated from the catalog plan's box dimensions (54 ft × 78 ft × 2 stories, 3-car front-load garage) — envelope massing with a designed interior: the interior is a DESIGNED wall-graph layout (22 rooms on story 1; upper stories keep the massing), and a schematic roof style (gable, 4 ft rise) is derived from the footprint (not a designed roof). Heights are declared at 10.5 ft/story.

Garage is a single-story attached volume sized from the plan's garage class (3 bays, front-load) — schematic massing, not a drawn garage.

Designed fenestration — declared design intent, not field-verified.

Room areas are net of partition thickness; the gross envelope is retained for reconciliation.

Interior layout is a designed wall graph; rooms are its enclosed faces net of partition thickness, not a schematic partition.

Each addressed story derives its rooms and partitions from ITS OWN walls; the shared envelope shell is counted once.

Stair geometry (riser count, riser height, tread depth, run length) DERIVES from the story height and the cited IRC R311.7 code constants — never stored or guessed; a schematic straight-run stair with no railings, stringers, or landings modeled.

The host room's area is reported net of the stair footprint; grossAreaBeforeStairSqft retains the pre-stair area for reconciliation.

Heights are per-building design values from the scheme — not construction dimensions.

Facade openings are a schematic rhythm for massing legibility — not designed fenestration.

Schematic furniture inferred from the room type — not an interior design.

Curb-appeal landscaping is presentation dressing derived from plan openings on schematic ground — not site data or a landscape design.

Floor finishes are a schematic guess from the room name (wood / tile / sealed) — no finish schedule was parsed. Legibility only, never priced.

Interior finish quantities from the plan's DESIGNED residential room graph (the A-105 finish plan source): per room the floor and ceiling finish area is the room polygon area (a DECLARED flat ceiling equal to the floor — no vaults, soffits, or sloped ceilings modeled), and the wall finish area is the room perimeter × the declared 10.5 ft story height (no deduction for openings; each room counts its own full perimeter, so both faces of a shared partition are finished). The floor-finish CODE is the room's OWN declared decor selection (a default-by-room-type planning convention where none was authored — not a product, SKU, or coordinated selection); a room with no finish is UNSCHEDULED, never invented. Quantities only — no dollar figures, no pricing — a planning-grade finish basis, not a measured construction takeoff.

Designed opening rough-opening AREAS from the plan's DESIGNED facade openings, grouped by anonymous rough-opening size-class (width × height in feet): per size-class the count and its total rough-opening area (count × width × height). windows/doors are the GROUND story; byStory lists each addressed story's own openings and windowsBuildingTotal / doorsBuildingTotal sum them across the building (upper stories carry their OWN designed openings, so this is NOT the ground story × storyCount). The rough opening is the framed wall opening, not the glazed/leaf area. Quantities only — no monetary figures — a planning-grade quantity basis, not a measured construction takeoff.

Planning-grade facade cladding areas from the rendered primary mass's vertical shell faces, grouped by the same north/south/east/west model-coordinate facing axes used by elevation export. These are elevation facings, not semantic front/right/rear/left labels or geographic bearings without a geo-anchor. Modeled net cladding area subtracts only rendered DESIGNED facade window/door rectangles. Attached garages and wings, gable triangles, foundation skirts, roof/parapet surfaces, trim, material system selection, and waste are excluded. Quantities only — not a measured construction takeoff. wall height assumed 2 stories × 10.5 ft; plan height fields absent.
