Cost to design and build a second-floor addition in Berkeley
Steve, a homeowner in Berkeley, wanted to add more space to his one-bedroom, one-bathroom home. He hired New Avenue to design and build a second story with an additional bedroom and an additional bathroom.
The original home was built in 1937. In our experience, older homes like this need four major renovations to bring them up to date:
An open living/kitchen area
A new owner’s retreat with bedroom and bathroom
A new accessory dwelling unit (ADU)
Whole-house sustainability upgrades
Steve recognized the value in his property and made a smart decision to update the home. New Avenue designed and built the addition, adding 418 square feet. Here are the plans.
What does it cost to add a second story to a house?
At the time of this project in 2017, the total cost to add a bathroom and a bedroom came to $313,825. This is turnkey pricing and includes every aspect of the project: team creation, design, engineering, permitting, construction, materials, and project administration.
