Lamont Bros. Design & Construction – ADU Services in Portland, Oregon
Lamont Bros. Design & Construction is a design-build firm based in Portland, Oregon, offering residential construction and remodeling services. Among their offerings, they work with homeowners interested in adding an Accessory Dwelling Unit (ADU) to their property — a growing option for those looking to make better use of their existing land.
An ADU is a secondary living space built on the same lot as a primary residence. As an experienced ADU contractor, Lamont Bros. helps homeowners navigate the process of planning and building these units, whether the goal is generating rental income, housing family members, or simply adding flexible living space to a property.
What an ADU Can Do for Your Property
Adding an accessory dwelling unit to your home can serve a number of practical purposes. Some homeowners choose to rent the unit out, creating a steady source of additional income that can help offset mortgage costs. Others use the space as a private home office, a guest suite, or accommodation for aging relatives — sometimes referred to as an in-law suite or granny flat.
Beyond the functional benefits, an ADU can also contribute to the overall market value of a property. As a detached ADU builder or backyard cottage builder, Lamont Bros. works with clients to design a unit that fits both the physical layout of the property and the homeowner's specific goals.
The flexibility of an ADU is part of what makes it an appealing option. The space can be adapted over time as needs change — what starts as a rental unit could later become a home studio or a comfortable space for visiting family.
A Design-Build Approach
Lamont Bros. operates as a full-service ADU builder, meaning they handle both the design and construction phases of a project. This integrated approach can simplify the process for homeowners, as design decisions and construction planning are managed under one roof rather than coordinated between separate firms.
Their team includes design consultants who work directly with clients to understand the scope of a project before construction begins. This helps ensure that the final result aligns with what the homeowner had in mind from the start.
For Portland-area homeowners considering an accessory dwelling unit — whether a detached ADU, a garage conversion, or a smaller JADU (Junior Accessory Dwelling Unit) — Lamont Bros. Design & Construction offers a structured process from initial design through completed construction.
