We’re a trusted home addition contractor in Federal Way known for beautiful, seamless results that feel like they were always part of your original home.
From Dash Point to Twin Lakes, we’ve helped Federal Way homeowners add real space and value — without uprooting their lives.
Why Home Additions Make Sense in Federal Way
Buying a bigger home isn’t always the answer — especially with rising home prices and limited inventory in South King County. That’s why more families in Federal Way are choosing to stay put and build out.
With a thoughtful home addition, you can gain the square footage you need while keeping the location, neighbors, and lot you already love. It’s a smart long-term investment that boosts both your lifestyle and your home’s value.
Plus, we live and work here — so we know the building codes, lot setbacks, permitting process, and neighborhood vibes that make every addition different.
Types of Home Additions We Build
Our team handles every phase of the construction process — from 3D plans to final inspection — so you don’t have to juggle multiple contractors. As a general contractor in Federal Way, we build all types of additions, including:
- Second-story additions

Common Questions About Building Additions in Federal Way
Do I need permits to build an addition?
Yes, nearly all additions in Federal Way require permits. We handle that for you, from drawings to inspections.
Will I need to move out during construction?
In most cases, no. We schedule work to minimize disruption and keep the site clean and safe.
Do you work with HOAs or unusual lots?
Absolutely. We’ve completed additions in tight backyards, steep slopes, and HOA-restricted communities.
