How We Work

Prefab or custom site built. Small space, an odd-shaped lot? We do it all. Not only we have 300 small home floor plans in our library to pick from, we also know 150 American and 50 European prefab home manufacturers, local Architects, and Builders. We will fit you with the best solution, saving you weeks of time. We have experience permitting ADUs and other accessory structures in many Bay Area jurisdictions and will get your permits faster. 


We cut out inefficiencies, delays, and permitting problems out of the process. 



We assess all materials and finishes for quality and toxicity, giving you a more energy-efficient, higher quality, healthier home.


We look at all options, handle the assessment and decision analysis, and give you the best solution for the best price.

What Our Clients Say About Us

Project: Casita Construction

When I started on this journey, I was a total beginner. With this team I was much more confident in my decisions.


Jane Z., Redwood City

Project: ADU in WUI zone

When your future ADU is by a creek or has an easement next to it, is in WUI zone or has to be ADA accessible, or all four as was our case – there is no way a homeowner can figure it out on their own. You want this team on your side. 

Sam D., San Jose

Project: Aging in
place ADU

I really appreciate Olesia and her team for review and advice. The project moved much faster than if I was doing it all by myself.

Anne L., Mountain View
ADU Specialist

Our Founder .

My name is Olesia, and I have extensive home-building experience. Building my first house in US (fifth, if we count all countries I had built in prior to that) turned out to be my most expensive education. I lost thousands of dollars just because I didn’t know how to ask the right questions at the right time. With Homewip, I am making a change in this market. We are here to make sure the homeowners are not taken advantage of just because it is their first construction project. Construction can be a nightmare – but it doesn’t have to be. Let us at HomeWiP create your true home – without the nightmare.
