This low‑poly connected suburban duplex is a twin residential building composed of two attached units joined by a central party wall under one continuous roofline. The model emphasizes readable massing and silhouette rather than fine ornament—broad faceted wall planes, simplified window and door apertures, and clear roof geometry let the piece read at typical hobby viewing distances on HO layouts and diorama displays. You receive one assembled master STL prepared at HO (1:87) scale. Miniature Reality supplies a single 1:87 master only; scale the file uniformly in your slicer to print at other scales (example: to print at OO/1:76 increase uniformly by ~14%, to print at N/1:160 reduce by ~46%). We do not provide multiple pre‑scaled STLs in this listing. The duplex is modeled as two near‑mirror halves sharing a continuous roof and party wall. Window and door openings are simplified cutouts sized to read from layout distance rather than individually modeled sashes. Exterior wall planes are intentionally faceted, producing broad flat faces that accept washes, color blocking and simple scenic detailing. The delivered geometry is a single assembled shell; for removable roofs, interior splits, hollowing, or separate printable subparts, request a custom conversion with specified split lines. Consider adding a thin scenic base (1–2 mm) for easier gluing and landscaping on HO layouts. The simplified eaves and overhangs are intentionally robust for FDM printing; if your machine struggles with unsupported eaves, add minimal slicer supports or orient the model to minimize long overhangs. This duplex is ideal for suburban neighborhood scenes, branchline residential areas and small vignette displays on HO layouts. Repeat the model to create rows, or mix with single‑family houses to increase neighborhood variety.
