The owner of a multi-family home in Berkeley came to New Avenue for a major remodel of a two-bedroom, two-bath rental unit. While parts of the unit were salvageable (e.g., the beautiful redwood and a few of the walls), this unit was almost entirely rebuilt. It needed a new foundation and major work in all areas.

The main art studio area is equipped with floor-mounted electrical outlets and receives tons of natural light through the unit’s clerestory windows and NanaWall, which easily folds back to open the entire front wall. The homeowners can enjoy the light and fresh air when the wall is open and will be protected from the elements when it’s closed.

When a couple in Berkeley, CA, looked at the shed in their backyard, they saw its potential to help them with their mortgage. They knew they could replace the shed with something better: an accessory dwelling that they could rent out, bringing in $3,000 or more in rental income—enough to pay for the new ADU and the mortgage on their main home. They also wanted a backyard home they could use for themselves or family as needed.

Most people choose to build a full ADU. Sometimes, though, a homeowner wants an accessory structure without a kitchen or an ADU with just a small kitchen facility. That was the case with one homeowner in Kentfield, CA, who asked us to create a detached gym with a bathroom and room for a bed.

The 934-square-foot home has a two-car garage (shared with the primary home), a loft, a kitchen, a bedroom, a bathroom, and plenty of storage space for the family’s outdoor adventure gear. Here's the floor plan.

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. Here are the plans and costs.

At $1,500 a year, the tax increase on this project breaks down to $125 per month. The homeowner easily recoups that with the savings on housing costs. The owner’s mother would have to pay $2,000 per month for a one-bedroom home of her own. If the family rents the unit out, they’ll bring in at least $2,000 per month in rent.

A homeowner in Mountain View asked New Avenue to create a 640-square-foot accessory dwelling that would serve as a comfortable home for a family member. Here’s what the project cost.

These Oakland homeowners wanted to build a detached office/studio that could also be used as a guest room. They also wanted to remodel part of the main home. The existing office would become a bedroom, and the existing half bath/laundry would be upgraded to include a shower. One of their requirements: preserve the property’s beautiful trees and tea house. Here’s the design.

The basement, which was entirely for storage, makes the perfect place to add an accessory dwelling unit. With a living/dining area, kitchen, bathroom, and patio, this will be a great home for a single person, a couple, or a pair of roommates. Plus, the homeowners don’t have to give up all of their storage. A storage room accessible from the main home is included in the plan.

Many homeowners find that their detached garages could be more useful as something else: a guest suite, a home office, or a rentable accessory dwelling unit (ADU). Here are plans and drawings for one garage conversion project in Berkeley.

Knowing the value an accessory dwelling can provide, he asked New Avenue to create an accessory structure that could be converted into a full accessory dwelling later. The designer created a 288-square-foot structure with space to add a kitchen and a shower in the future. Here are the drawings.
