The floor plan, not the price tag, is often the real profit center or loss maker in a first‑time purchase. While buyers compare cost per square meter, corridors, window placements and room adjacencies quietly set the trajectory for future resale value, acoustic comfort and daylight exposure.
In property economics, layout acts as a hidden marginal effect multiplier. A bedroom sharing a wall with an elevator shaft or a living room facing a narrow light well does not show up in price per square meter, yet it directly lowers perceived utility and liquidity when the owner tries to sell. Brokers informally discount units with poor cross‑ventilation, long internal corridors and fragmented living spaces, because each of these elements increases entropy in daily use: more dead corners, more noise paths, fewer flexible zones.
Metrics such as daylight factor and sound transmission class reveal why near‑identical units in the same building trade at different prices. A layout that stacks noisy functions together and concentrates glazing on one facade can feel smaller, even when the measured area is identical. Conversely, a plan that aligns structural grids, shortens circulation and enables multiple furniture configurations effectively expands the functional footprint without adding a single square meter, and buyers in the secondary market tend to pay for that invisible efficiency.
