The super-rich are combining multi-unit townhomes into mega-mansions: report

March 9, 2026 - 03:03

A new trend is emerging in luxury real estate markets, where the ultra-wealthy are purchasing multiple adjoining townhomes and combining them into sprawling, single-family mega-mansions. This practice, particularly noted in high-demand urban areas, is reshaping neighborhoods and property landscapes.

The process involves buying several contiguous units, often in newer developments, and undertaking extensive renovations to unify the spaces. The result is a custom-built urban compound that offers the square footage and amenities of a grand estate within a city setting. These combined properties frequently feature private elevators, expansive entertainment suites, interior courtyards, and dedicated spaces for staff, all while maintaining a relatively discreet exterior footprint.

This movement is driven by a desire for substantial living space in prime locations where traditional single-lot mansions are simply unavailable. It reflects a shift in how affluent buyers view urban living, prioritizing privacy and customization even within multi-unit buildings. The trend also highlights the significant financial resources required, as the strategy involves not only the purchase of multiple high-value properties but also the cost of complex architectural and construction work to seamlessly blend the separate units into one cohesive home.
