Add Space, Comfort, and Value to Your Home

When your home feels too small, moving isn’t always the best answer. A custom home addition can give you the extra square footage you need while keeping you rooted in the neighborhood you already love. At Amplified Renovations, our design-build team helps homeowners in Portland, OR, and Vancouver, WA expand their homes with seamless additions that look and feel like they were always meant to be there.

Why Choose a Home Addition Project Instead of Moving?

  • Stay in Place, Gain More Room – Avoid the stress of house-hunting, moving costs, and competitive markets. An addition allows you to keep your location, neighbors, and schools while getting the space you need.

  • Improve Your Home’s Value – Well-designed additions can deliver strong resale returns. Adding a new kitchen, primary suite, or ADU often provides some of the highest ROI in the remodeling world.

  • Tailored to Your Lifestyle – Maybe you need space for a growing family, a private office for remote work, or a comfortable guest suite. A home addition can be customized to match your exact lifestyle.

  • More Cost-Effective Than Buying New – In the Portland and Vancouver real estate markets, upsizing to a larger home can cost far more than enhancing your current one. Additions let you invest in your property strategically.

Why Homeowners Trust Amplified Renovations

Design-Build Expertise

Instead of juggling multiple companies, you’ll work with one dedicated team from concept through completion. Our designers and builders collaborate seamlessly, ensuring your vision is carried through every stage. This integration means fewer delays, smoother communication, and a better final product.

Transparent Pricing

One of the biggest concerns with any remodeling project is cost. At Amplified, we pride ourselves on clarity. You’ll receive detailed estimates, realistic allowances, and consistent updates. Our goal is to eliminate surprises and empower you to make informed decisions.

Built for the Pacific Northwest

Portland’s heavy rains and Vancouver’s seasonal shifts mean your addition must be more than just beautiful; it has to be durable. We select materials and construction methods that perform in the PNW climate, from moisture-resistant siding to energy-efficient insulation.

Permit & Zoning Knowledge

Adding onto your home requires more than hammer and nails; it demands careful navigation of building codes. Our team has years of experience working with the City of Portland Bureau of Development Services and Clark County permitting departments. We streamline the process, so you don’t have to worry about unexpected compliance issues.

Local Reputation

Our reputation is built on delivering projects that look like they were always part of the original home. Homeowners across Portland and Vancouver trust us for craftsmanship, communication, and a commitment to standing behind our work long after the project is finished.

Types of Home Additions We Build

Primary Suite Additions

Gain a private retreat with a spacious bedroom, walk-in closet, and spa-style bathroom. We can design suites on the main floor for aging in place or upstairs for maximum privacy. In Portland, where lot sizes are often smaller, a rear or side addition can unlock hidden potential.

Kitchen Expansions & Bump-Outs

If your kitchen feels cramped, a bump-out or full expansion can dramatically improve your home’s flow. Popular upgrades include larger islands, additional storage, and open-plan layouts that connect seamlessly with dining and living areas.

Family Rooms & Sunrooms

A family room or sunroom addition provides a flexible gathering place filled with natural light. Whether you want a casual media room or a four-season sunroom, we design spaces that maximize comfort and usability year-round.

ADUs & In-Law Suites

Accessory Dwelling Units (ADUs) and in-law suites are increasingly popular in Portland and Vancouver. These units can provide income as rentals or offer comfortable living for aging parents, adult children, or long-term guests, all while meeting zoning standards.

Second-Story Additions

If your lot doesn’t allow for outward expansion, building up may be the solution. A second-story addition can double your living space without reducing your yard. We ensure structural integrity and design continuity, so your home maintains balance and curb appeal.

Garage Conversions

Transform underutilized space into something meaningful. Garage conversions are ideal for home gyms, offices, or guest bedrooms. We upgrade insulation, lighting, and finishes so the space feels fully integrated.
