Frequently asked questions
Can you add a second story to my home?
In many cases, yes; it depends on your existing structure and local requirements, which we assess during pre-construction planning.
Will the addition match my existing home?
That's the goal. We detail the addition so rooflines, facades and interiors integrate rather than clash.
Will I need to move out during construction?
It depends on the addition's scope and how it connects to your existing home; we'll walk through what to expect for your project during the site visit.
Is Horst Construction licensed and insured for structural work?
Yes, we're fully licensed and insured in California, License #1124176, with structural engineering coordinated as part of every addition.
