If you have pets at home, that could be one reason for the sneezing at home that improves away from home. Could also be that there is a mold issue in your house, or that you're allergic to dust mites - most office buildings have central air circulation that may remove dust better than home air circulation systems, especially if the air filter on your home air system isn't changed frequently.
