Polar Bear Construction builds accessory dwelling units (ADUs) and home additions for homeowners in Snohomish and nearby towns. We work on residential properties only, not commercial projects, rentals or handyman jobs.
What is the difference between an ADU and a home addition?
An addition makes your existing house bigger: a new bedroom, a larger living area, more room on the main floor. An ADU is a separate, self-contained living space on the same property, attached to the house or detached from it, with its own kitchen and bathroom. That is why ADU projects draw on the same work as our kitchen remodeling and bathroom remodeling.
How much does an ADU or addition cost?
Size, the site, the foundation, and how much plumbing and electrical the new space needs all drive the price. Every ADU and addition is quoted on its own after we learn what you want to build. First-time clients get 10% off for first-time clients.
Should I build an addition or finish the basement?
If the house already has an unfinished basement, basement finishing is often the simpler way to add living space. If it does not, or the space needs its own entrance and kitchen, an addition or ADU is the answer. Send the contact form or call (425) 953-3898 and we can talk through which fits your property.
