"The quality of the work was awesome and the workers were very professional and answered any questions I had along the way of the work. My only critique is that the timelines initially given and even at the beginning of the project were off by a couple of weeks. Some of the communication in that wasn’t always clear."

Second story addition building services FAQs

Many homeowners find adding a second story a worthwhile investment. It significantly increases their home's value and provides more living space to enjoy. It’s especially beneficial for homeowners with a limited lot size who want to add square footage without building out. 

The time required to build a second story depends on the size and complexity of the project. While most additions are completed within two to six months, some larger or more intricate designs may take up to a year. The permitting process, weather conditions, and material availability also affect the timeline.

Your budget, location, and lot size will determine if it’s best to build up or out. If you live on a lot with limited space, building up allows you to add square footage without taking up additional ground space. Building out is often best if you live in an area with zoning restrictions or want to live in your home while it’s under construction.
