US buyers are used to large houses and centralized systems. In Portugal, they are shocked by small rooms and lack of air conditioning.

Open Concept: If the wall between the kitchen and living room is not a load-bearing (structural) wall, we suggest knocking it down (or simulating demolition in the design). This is crucial to American taste.

Voltage: They use 110V; we use 230V. Explaining that your "dual voltage" electronic devices work, but large appliances don't, is a consulting service they value (Total Care).

HVAC: For them, heating is not "an oil radiator." They value ducted (invisible) systems. If your house has pre-installed AC, this has to be the number one highlight.
