This is an illustrative planning example, not a real client story. It shows how a household might approach a move from a large landed home to a penthouse, and the questions worth answering along the way.
The first step is to clarify what the family wants to keep. Some households value space for hosting, others want less upkeep, and others want to stay in the same neighbourhood. Writing these priorities down makes the rest of the decision easier.
Next, understand the sale. The current home's value, its tenure and how quickly it might sell all shape the timing. Many households sell first, or line up a purchase with a completion date that gives them room to move.
Then compare penthouses on the things that matter in daily life: floor plan, views, facilities, parking, service charges and how the building is managed. Test the layout against your furniture and your routines before you commit.
Finally, plan the move itself. Declutter early, decide what to keep, and allow time for the transition. A good agent coordinates the sale, purchase and timing so the household is not left between homes.
