Convert your house from single to double story with a functional second-floor addition. Our design and build team at Zenith Design + Build will increase the space and value of your home.
Partial second-story additions are ideal for those who need a smaller amount of space in the form of one or two extra rooms and a bathroom.
A full second-story addition matches the size of the first floor and doubles the house’s size, offering space for multiple rooms, bathrooms, and living areas.
A second-story addition to your garage adds valuable space that may be used as an office, bedroom, or additional dwelling unit for family or rental income.

The cost of a second story addition depends on its size and scope, as well as selections. Most additions that Zenith Design + Build undertake begin at around $70,000 - $75,000.
A second-floor addition costs more because, typically, the existing roof has to be removed entirely and replaced. The first floor may also require the installation of additional structures to ensure the second-floor addition is securely supported and connected to the first floor.
Building a second-floor addition takes a few months, depending on the size of the addition, design features, and how much of the first-floor walls need fortifying.
