Why Historic Review Expertise Matters
Preserving Portland's Historic Neighborhoods
Portland’s historic districts are among the city’s most cherished neighborhoods, and preserving their character is vital as the city evolves. If you own a home in one of these districts—or are thinking of buying in one—you need a design and construction partner who understands both your home’s unique architecture and the requirements of the Historic Resource Review process. That’s where we come in.
The Importance of Working with Experienced Designers
At Arciform, we specialize in designing for Historic and Conservation Districts, such as Irvington, Laurelhurst, and Eastmoreland. We know how to create thoughtful additions and remodels that respect your home’s historic character while meeting modern needs. We also know how to prepare, present, and navigate the permitting process so your project moves smoothly from concept to approval.
Our Approach to Historic and Conservation Districts
Thoughtful Additions and Remodels
Whether you’re adding a dormer, updating windows and doors, or creating a new outdoor space, we ensure your design aligns with the city’s standards for balance, proportion, materials, and architectural details.
Navigating the Historic Review Process
Because we’ve worked on many Historic Review projects across Portland, we can set realistic expectations for budget, timeline, and outcomes before you start. Our expertise helps clients avoid costly mistakes and ensures projects meet city requirements from the beginning.
Setting Realistic Expectations for Your Project
Budget, Timeline, and Design Outcomes
Understanding the Historic Review process allows us to provide clients with accurate guidance on costs, schedules, and design feasibility. This upfront clarity helps homeowners feel confident as their project moves forward.
Aligning with City Standards: Balance, Proportion, Materials, and Details
Every detail matters in historic remodeling. From window profiles and roof pitches to materials and millwork, we make sure your project respects the integrity of your home while providing the function and beauty you want.
Supporting Your Project Beyond Design
Historical Preservation Financial Benefits for Owners of Historic Properties

Historic Review with Arciform
What is Historic Resource Review?
It’s the City of Portland’s process for exterior changes in Historic and Conservation Districts to ensure the work respects neighborhood character and architecture.
What type of district is my home in - Historic or Conservation?
- A Historic District is designated by the City and listed on the National Register of Historic Places.
- A Conservation District is locally designated by the City and focuses more on overall neighborhood scale and character rather than detailed historic features.
Knowing your district type helps tailor the design and review process.
Does Arciform handle historic district permits and approvals?
Yes — we design, prepare drawings, submit documentation, present to the permitting office, and guide the project through approval, specifically for historic district homes.
What kind of exterior changes typically require historic review?
Additions, dormers, new windows/doors, changes to exterior siding, large visible alterations. Interior only work or very minor, nonvisible changes may not require review.
How does the design approach differ for historic homes and buildings?
We make sure your project:
- Aligns with the home’s original scale, massing, rooflines, materials.
- Keeps or repairs original historic materials whenever feasible.
- Designs any new work to be compatible but clearly distinguishable so the historic core remains legible and honored.
Why choose Arciform for this?
Because we specialize in historic district remodels, we know the requirements and pathways. That helps you avoid costly surprises, manage timeline/budget risks, and ensure the neighborhood and review board support your project.
