Our Process

How Additions Works

From first call to final walkthrough—here’s what to expect when you work with us.

01

Consultation & Feasibility Review

We meet at your home to discuss your goals — whether it's an extra bedroom, expanded living room, or second-story addition. We assess your property, zoning requirements, and existing structure to determine what's feasible.

02

Design, Engineering & Permits

We develop plans for your addition, coordinate with structural engineers, and handle the permitting process with your local building department so construction can begin on a solid foundation.

03

Foundation & Framing

Our crew pours the foundation (if required), frames walls, installs roof structures, and ties the new addition into your existing home — ensuring structural integrity and weather-tight connections.

04

Systems, Finishes & Walkthrough

We install electrical, plumbing, HVAC, insulation, drywall, flooring, paint, and trim. After final inspections, we walk you through the completed addition to ensure it meets your vision.

Why Choose Us

Why Our Additions Stand Out

Sometimes your home is perfect in every way — except for size. Whether your family is growing, you need a home office, you want to add an in-law suite, or you simply want more living space, a home addition lets you expand without the expense and disruption of moving.

Dexica Construction specializes in building custom home additions that integrate seamlessly with your existing structure. We handle room additions, second-story additions, garage conversions, bonus rooms, and accessory dwelling units (ADUs). Our process covers everything from the first design conversation and structural engineering through permitting, construction, and final finishes.

Based in Hubbard and serving the Portland metro, Salem, and the Willamette Valley, we've helped homeowners add the space they need while increasing their property value. An addition is one of the biggest investments you can make in your home — we make sure it's done right, built to code, and finished to a standard that exceeds your expectations.

Seamless Integration

We build additions that look and feel like they've always been part of your home — matching rooflines, siding, trim, and finishes so the new space blends naturally with the existing structure.

Structural Expertise

Home additions require careful structural planning. We coordinate with engineers to ensure proper foundation work, load-bearing connections, and code-compliant framing from the ground up.

Complete Project Management

From initial design through permitting, construction, and finishing, we manage every phase of your addition project — keeping you informed and the project moving forward on schedule.

Built to Code

Additions involve permits, inspections, and strict building code requirements. We handle all the regulatory coordination so your new space is safe, legal, and fully compliant.

FAQ

Common Questions About
Additions

We build room additions (bedrooms, bathrooms, living spaces), second-story additions, garage conversions, sunrooms, in-law suites, bonus rooms, and accessory dwelling units (ADUs). If you need more space, we can build it.

Most home additions take 2 to 4 months from groundbreaking to completion, depending on the size and complexity of the project. The permitting process can add additional time before construction begins. We'll provide a realistic timeline during your consultation.

Yes. Home additions require building permits in virtually all Oregon jurisdictions. We handle the entire permitting process — including plan submission, engineering coordination, and scheduling inspections — so you don't have to.

Absolutely. We take great care to match the existing roofline, siding material, trim style, and overall aesthetic of your home so the addition looks like it was always part of the original design.

In many cases, yes. Second-story additions require structural analysis to ensure your existing foundation and framing can support the additional load. We coordinate with structural engineers to determine feasibility and design the right solution.
