Triangle Bar Group: Design & Build Services for the Pacific Northwest
Triangle Bar Group is a full-service design and build contractor based in Portland, Oregon. They specialize in designing and constructing new homes, additions, remodels, and accessory dwelling units (ADUs). Their approach brings together design, budgeting, coordination, and construction under a single point of contact, reducing the complexity of managing multiple contractors across a project.
From the first design meeting through to the final walkthrough, Triangle Bar Group acts as the primary point of accountability. Whether the project involves breaking ground on a new custom home, building an addition, or reimagining an existing space, they apply careful craftsmanship and construction methods throughout the process.
Architectural Design and Construction Documents
Triangle Bar Group offers architectural design services tailored to residential projects, including new construction, remodels, and ADU builds. Their design process typically moves through several key phases:
- Initial consultation to understand client needs, goals, and budget
- Site assessment covering topography, zoning regulations, utilities, and environmental factors
- Conceptual sketches including floor plans, elevations, and basic 3D representations
- Design development incorporating dimensions, materials, and technical systems
- Detailed construction documents suitable for permitting and contractor bids
Their construction documents include architectural, structural, mechanical, and electrical plans, along with material and construction method specifications. Triangle Bar Group is familiar with the permitting process in Portland and surrounding areas, and their documents are developed with local code requirements in mind, which can help reduce delays during the approval process.
As both designers and builders, they are able to translate conceptual ideas into clear, accurate drawings that contractors can follow with confidence. They coordinate with engineers and other consultants throughout the process to ensure technical details are resolved before construction begins.
ADU Building Services in Portland and Vancouver
Triangle Bar Group has experience designing and building a range of accessory dwelling units, including detached ADUs, backyard cottages, and other independent living spaces. They handle the full scope of an ADU project — from initial design and permitting through to construction and finishing — making them a practical option for homeowners looking for a single contractor to manage the entire process.
ADU projects they take on can serve a variety of purposes, including:
- Long-term rental units
- Guest accommodations
- Space for family members
- Home office or flexible living space
A recent example of their ADU builder work includes a completed project in a historic Vancouver, Washington neighborhood. The project involved constructing a one-bedroom detached ADU in the backyard of an older home. Despite constraints related to the existing home's position on the lot, Triangle Bar Group designed a unit with an open living area, full kitchen, and modern bathroom. The design incorporated high-placed windows to allow natural light while maintaining privacy between the two units. The ADU includes its own entrance with a small patio area, while the main house retains its front yard and parking space.
This type of project reflects their general approach to accessory dwelling unit construction — balancing function, privacy, and long-term value within the specific constraints of each property.
For homeowners in the Portland and Vancouver areas considering an ADU, addition, or custom home project, Triangle Bar Group offers design consultations to help assess options and determine project fit.
