If you ask a contractor for an estimate, you’ll most likely get a quote that’s just plain wrong. We’re talking a +/- 30% difference (or worse). 30% too high, and you won’t get the best value for your money. 30% too low, and you may be left with a hole in the ground while you scramble for financing.

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.

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.

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.

Brian and Dawn’s designer created plans to replace the existing accessory structure with a new 352-square-foot detached studio with a half bath. A deck and firepit give the owners and guests a comfortable place to relax or entertain.

The designer created plans to extend the owner’s suite in the main home, giving the homeowners more space in their bedroom and bathroom.

Here are the plans.
