.casa domains

The .casa domain means "house" or "home" in Spanish, Italian, and Portuguese, giving it instant meaning across a large part of the world. It is a natural fit for real estate agents, property listings, home-goods and furniture brands, interior designers, builders, and hospitality businesses such as guesthouses and rentals. The word is short, warm, and easy to say, so a .casa address feels inviting and is simple to remember. Registration is open worldwide with no restrictions. For a business built around homes and property, especially one serving Spanish-, Italian-, or Portuguese-speaking audiences, a .casa domain puts a friendly, on-theme word at the center of the brand, describing what the company does while adding a personal, homely tone.
