• Home Additions by Builder Hammer & Hand


You don’t have to leave the home you’ve loved for years just because you’re starting to outgrow it. We specialize in home expansion projects including second story additions and dormers, kitchen or bathroom bump-outs, basement conversions, and first story room additions.

Fit In or Stand Out

With a deep appreciation for the range of architectural expression and heritage in Portland and Seattle, we collaborate with designers and architects to ensure that your addition makes architectural “sense”: either a natural and seamless extension of your home’s current aesthetic or an intentional and tasteful departure.
