What is it called when houses receive improvements, such as new kitchens?

The term that describes when houses receive improvements, such as new kitchens, is "renovation." Renovation involves making updates or enhancements to a property, improving its aesthetics, functionality, and overall value. This can include a wide range of activities, from modernizing kitchens and bathrooms to upgrading electrical systems or adding new features. It signifies making something new again by repair or improvement.

Restoration, on the other hand, typically refers to returning a property to its original state, often focusing on preserving historical elements. Reconstruction suggests rebuilding a structure that has been damaged or destroyed, while reinforcement generally relates to adding strength or support to a structure, such as enhancing its structural integrity against environmental forces. These terms focus on different aspects of changes or improvements to properties, which is why renovation is the most appropriate choice for this context.
