A Plus Builders Construction
ApB was founded in 2016 by Anh Nguyen after leaving his job of 8 years as a project manager / construction manager on multi-million dollar institutional design build projects. ApB has in the short span of time, completed whole house renovations, kitchen and bath remodels, dry rot removal & structural repairs, a seismic retrofit and development and renovation of an apartment complex. ApB’s high quality craftsmanship and best value approach has been in such demand that our current bookings are closed until the end of 2018. However, we would surely enjoy talking to you about future projects.
Anh holds Masters degrees in Architecture as well as Urban Planning from UC Berkeley and has been working in the San Francisco Bay Area for the past 10 years.
