HOME ADDITIONS
Seamless additions that expand your home and match its character down to the detail.
What to Expect
Home Additions by
Josiah Construction
A home addition is the most personal project we build — it has to match your existing home perfectly, from the roofline to the trim profile to the floor. We've done it enough times to know where the details matter most.

Built to a Higher Standard
Every project is entered into as a partnership — Master-carpenter-led, on schedule, with no corners cut. We'll walk it together at the end and make sure it lives up to the standard.
