Home Additions
Home Additions
From new rooms to second-story expansions, we focus on clean tie-ins, permitting realities, and finishes that match the existing home.
Serving Oregon & Washington. Licensed, insured, and detail-driven from first call to final walkthrough.
Scope
What’s Typically Included
Clear scope reduces surprises. These are the most common items we plan for and build.
- Scope + feasibility review (footprint, setbacks, structural tie-in)
- Permitting coordination expectations (as required)
- Foundation and framing scope definition
- Roof tie-in and weatherproofing approach
- Window/door package planning
- HVAC/electrical/plumbing coordination (as needed)
- Interior finishes for the new space (as scoped)
- Finish transitions to existing home (trim, flooring, paint matching plan)
Decisions
Popular Choices
Helpful decision categories homeowners usually choose between. No brand lock-in.
- Footprint: bump-out vs. full room addition
- Foundation: crawlspace tie-in vs. slab (site-dependent)
- Roof tie-in: match existing pitch vs. new geometry (where feasible)
- Windows: standard packages vs. upgraded performance
- Interior finish level: match existing vs. updated across adjacent rooms
- Exterior: blend and match vs. intentional contrast (done tastefully)
Planning
Timeline & Cost Drivers
Practical guidance to help you plan. We’ll confirm specifics after a site visit and scope review.
Typical Timeline
10–24+ weeks (typical), depending on permitting and scope
Every project is different. Here are the most common factors that affect schedule:
- Permitting and inspection timelines
- Foundation and structural complexity
- Weather windows for exterior phases
- Long-lead items (windows, doors, specialty materials)
- Systems tie-ins (HVAC, electrical, plumbing)
Cost Guidance
Additions are driven by size, structural complexity, systems tie-ins, and finish level. Permitting and exterior tie-in details can also impact cost.
What affects cost:
- Square footage and structural complexity
- Foundation type and site conditions
- Roof tie-in complexity and weatherproofing
- Window/door package level
- Systems extensions (HVAC/electrical/plumbing)
- Finish level + transition work into existing spaces

Process
How We Deliver It
A calm build comes from good sequencing and clear communication.
-
Step 1
Feasibility + scope
We confirm goals, budget direction, and structural/permit constraints before decisions get locked in.
-
Step 2
Plan + permit
We align a build plan and permitting path so the schedule is grounded in reality.
-
Step 3
Build + tie-in
Foundation, framing, roof/exterior, then systems and interior finishes. Tie-ins are detailed carefully to prevent future issues.
-
Step 4
Finish + transition
We complete trim, paint, and transitions so the new space feels like it belongs.
FAQ
Questions We Hear Often
Do additions require permits? +
Most additions do. We’ll discuss what applies to your scope and how it affects schedule and sequencing.
Will it look like part of the original house? +
That’s the goal. We plan exterior proportions, materials, and transitions so the addition blends cleanly.
Can you do an ADU? +
Depending on jurisdiction and site conditions, an ADU may be possible. We can discuss feasibility and next steps.
How do you handle tie-ins to the existing structure? +
Tie-ins are where quality shows. We define transitions and water-management details early so the new work performs and looks intentional.
Can we keep living in the home during an addition? +
Often yes, depending on scope and access. We’ll discuss sequencing and what the most disruptive phases will be.
