An "executive home" is a type of house that is usually bigger and fancier than a regular house. It is usually located in a nice neighborhood and has lots of cool features like a big backyard, swimming pool, lots of bedrooms and bathrooms, and sometimes even a game room or movie theater.
People call it an "executive home" because it is often owned by someone who is a boss or manager at their job, which means they have a lot of responsibility and make a lot of money. Just like how a manager at a company has a fancier title and more important job than someone who works in a regular position, an executive home is fancier and more expensive than a regular house.
So basically, an executive home is like a really big, fancy house that is owned by someone who is a big boss at their job.
