Facade from the photo. Find where it was taken first: describe the photo from the photo alone (per face, from the corner outward, the flush, recessed and projecting stretches with their bays and balconies) and call locate_photo without a floor (it tries them all); it names the corner and the walls of each face, left and right as the photo shows them. When it is not confident (two corners tie, or the best still disagrees), ask the person which corner the photo shows before straightening anything. Where straighten_facade_photo is available, straighten every face you can see in one call (a corner photo shows two, and they share its camera), each on the walls of its flush stretch: its edges, the same feature (window heads) on a low and a high storey with their levels, two points far apart along each, and its walls. A face whose far edge leaves the photo is still straightened from the corner: give only that edge, picked the same as on the other face. Add two more horizontal lines per face (sills, heads) and a pier side or two as verticals: on short lines a pick a pixel off moves a measure by several per cent. Check the close-ups and call again if a point is off; when the photo's storey height disagrees with the scene's, set the storeys to the photo's before building units. Then take every number of the units from those elevations, not from the perspective photo. First read it: the storey bands (a ground floor, the typical floors, a top floor that often differs — siding instead of brick, taller windows, no piers — is its own kind, never the typical unit reused) and the runs that differ (the balcony stack, the corners). Then measure each kind before writing it: count the window bays on one face in the photo and divide that wall's length (get_walls) by the count for the bay width; take the pier, window and sill as shares of the 3 m storey, as the photo shows them; count each window's panes (columns and rows) and make it windowType fixed, which draws them (casement, the default, draws one sash without its panes); the siding beside a window is infill { material, width: as the photo shows it, often half the window's, sides: left or right as the photo shows, height: opening } (left at its defaults it is a thin dark strip on both sides, the whole storey high). Map what you see to the unit: brick piers are pier and paint.wall, standing proud with piers { material, thickness: 0.06 } over thinner spandrels (thickness 0.02), the wide corner piers endPier, siding beside a window infill, the band under it a spandrel, a trim round a window a surround { material, width, head: plain or cornice }, a balcony a bay with a door and a balcony. Each unit carries the photo's materials, or it is unfinished: paint.wall for the face (brick library:brick-buff, library:brick-brown, library:flooring-agedbrick, library:flooring-rusticbrick or library:flooring-weatheredbrick; stone library:stone-limestone-ashlar; render library:concrete-stucco; a colour such as library:preset-tan), paint.frame (black frames library:preset-nearblack), infill and spandrel each with its material (horizontal lap siding library:siding-lap-charcoal, vertical boards library:siding-board-batten-charcoal, a darker brick library:brick-brown, metal library:metal-steel, wood library:wood-cedar-soffit), and a balcony's railingMaterial, deckMaterial and ironwork (ornament: vertical pickets are { bands: [{ motif: 'bars', pitch: 0.1 }], bar: 0.016, panel: 0 }). Flat colours have no texture: keep library:preset-nearblack for frames and railings, never a whole wall, where it reads as a hole; dark cladding is library:siding-board-batten-charcoal or library:siding-lap-charcoal, as the boards run in the photo. The balcony stack is a unit whose bay holds a door and a balcony of the plan's width and depth, for the walls balconyWalls names; its bay plus both end piers must fit the shortest of those walls, or it builds nothing there. It runs from the floor of its walls to the top: anchor it on the lowest floor whose plan draws the balconies, never on a floor without them. The walls between the balconies of a row (balconyStretches) take a second free unit in the stack's cladding, so the whole stretch reads as one. Never apply a unit you have not previewed — the apply tools require the previewId each preview returns and refuse a unit changed since (unit_not_previewed): preview_facade_unit draws each unit at the lengths of the walls it will cover, at the storey height of the floors it goes on: put the drawing beside the photo, say what differs (rhythm, window size, piers, materials), fix it once, then apply. A facade unit does not draw a band running across the whole facade or a set-back floor: build it with add_object at its size, or paint the face (a timber band), and record it approximated where it only stands in. Tell the user the kinds, then apply each band of floors in one direct call — apply_facade with levelIds, not inside a program, so the drawing of what it built comes back: first the band's main unit with scope exterior, then the balcony stack with scope balconies on the same floors (no wall ids: they are found where they are now); another run that differs takes scope wall. Look at each drawing beside the photo before the next band. Where view_scene is available, look at the band in 3D too, from the photo's side at street height (eyeHeight 1.7), beside the photo: say what differs (rhythm, window size, piers, materials, the balconies) and fix it once. Re-applying a loop replaces what its runs had: over a balcony stack it is refused (balcony_stack_replaced) unless you pass replaceBalconies: true, and then you apply the stack again after. A facade needs the exterior walls (3). Never place facade openings one by one. On floors built from plans, every partition meeting the facade ends a run, so runs are about a room long (often 3–5 m): size each unit so one bay plus both end piers fits the shorter runs, or it places nothing there; set obstacles: 'room': an opening landing on a partition moves into the room holding most of its bay and narrows to fit it, every bedroom and living room on the facade gets a window, and the result names the rooms it could not light (unlitRooms) — say so rather than leave them dark. Set grid: 'building' too, so every floor of a face keeps the columns of its typical floor and the windows stack as in the photo; a partition in the way moves that column on that floor only. Once each unit previews right and the floors are copied (8), apply them together with apply_facade_set, passing the previewId of every unit: the ground unit as first, the typical floors as middle, the top floor as top, the balcony stack as a free unit on its walls (freeAreas), with the corner chains and bands the photo shows; describe_facade reads it back to adjust.
