A 400-unit residential complex and an 18-unit boutique building can carry the same energy class, the same price per sqm, and the same marketing language. They are not the same investment.

The differences are structural, and they compound over time.

Resale competition. In a large complex, your neighbours are your competitors. When you decide to sell or re-let, you are pricing against dozens of equivalent units in the same building or phase. In an 18-unit building, scarcity is built in — there is no internal competition, and available units are rare enough to support price discipline.

Maintenance governance. In Romania, developers hand off building management to resident associations (asociatii de proprietari) at handover. In a 200-unit complex, maintenance decisions are made by majority vote of a large, heterogeneous owner pool with conflicting priorities. In a building with 18 units, each owner controls approximately 5.5% of every decision. Building condition over a 10-year horizon is largely a function of HOA quality — not the developer’s original specification.

Location logic. Large-scale projects require large, affordable plots. In practice, that means the periphery — where land is cheap enough to justify the unit count. Boutique projects can occupy central infill sites where no 400-unit complex could be built. Location compounds. Peripheral convenience does not.

Specification integrity. A developer delivering 18 units has a reputational stake in every detail. Cost-cutting on 400 units is invisible until it isn’t.

These are not arguments for boutique over mass-market categorically. They are variables worth modelling before you commit capital.
