Juxtaposition of Old and New: Contemporary Townhouse Adjacent to a Tiled Old House

Design a contemporary Taiwanese townhouse specifically for how it sits against its unrenovated neighbour, making the juxtaposition the subject. Show two houses side by side sharing a party wall and roughly matching in height and floor levels, since both were built to the same plot and code. Detail the new house as a calm plane of pale grey render with deeply recessed openings, a bronze metal screen across the balconies and a flush integrated garage door, everything aligned and nothing surplus. Detail the older neighbour with equal care and no condescension: beige and brown mosaic tiles laid in a two-tone banded pattern, blue-tinted glass in aluminium sliding frames, wrought iron security grilles with a scroll motif at every window, a balcony enclosed after the fact in aluminium and frosted glass, three air conditioning condensers stacked on brackets, a satellite dish, and a red plastic sign for the family's ground-floor business. Show the party line between them as a single sharp vertical joint where the two eras meet with no transition. Detail both as clearly lived in and equally real. Show the older house as the more colourful and the more informative about the street. Set it on an established Taiwanese lane. Show even overcast light. Photorealistic, juxtaposed, restrained grey beside patterned tile, straight-on street elevation view.
