ADUs and Home Additions in Camas, WA

Extra rooms rarely fail because of the idea behind them. They fail at the seam where new framing meets old, where a roofline, a floor height or a wall plane does not quite agree with the house it joins. Water finds those seams first, and so do drafts and cracks. An addition also means opening an exterior wall and living beside the work, so structure, weather protection and permits all have to fall into the right order. That coordination is why a well planned addition calls for a builder who understands the existing home as well as the new space.


Houses from the early 1900s still stand in a small part of downtown Camas, a legacy of the paper mill that built the city. Older homes like these often have original trim, siding and window styles that differ from current building products, so a new room has to be designed around what is already there. Matching rooflines and exterior details takes careful planning on a house with that much character. Seeing how a bedroom, sunroom or home office will read against the original home before framing starts makes every later decision easier.


We are Covas Construction, an experienced home additions contractor in Camas, WA, and we build bedroom additions, sunroom additions, kitchen expansions, home offices, garage additions and bonus rooms. Each project begins with design consultations and drawings, and we match rooflines and siding to the existing house so the new space looks like it belongs to the original design.

We are locally owned, licensed and insured, with over 20 years of hands on building behind every job.

Camas: Home Additions Contractor

About Camas, WA

Paper shaped Camas from the start. Founded as a mill town in 1883 and incorporated in 1906 as LaCamas before taking its present name, the city grew around a paper mill that still stands at the west end of downtown. Today the historic core centers on Northeast Fourth Avenue, where preserved older buildings line the street.


Camas sits on the north bank of the Columbia River in Clark County, Washington. By the 2020 census, the city counted 26,065 residents, up from 19,355 in 2010, and neighborhoods such as Grass Valley grew along with it. Both the Camas Public Library and Lacamas Lake are part of everyday life for the families who live and work here.


Water and woods fill much of the spare time. Lacamas Park, with Round Lake and the Camas Potholes, is a favorite for walking, and the Lacamas Heritage Trail gives walkers another route through the park system. In spring the camas lily fields add color to the local landscape.

Matching Newer Homes With a Home Additions Contractor in Camas, WA

Newer homes bring their own matching puzzle. Roughly half of the homes in Camas were built after 2000, according to housing data, and on a house that recent the original materials are often still available. The goal then is a seamless match in roof pitch, siding profile and window trim, not a contrast that looks like an afterthought.


When the house is relatively new, the design question shifts from repairing the past to matching it. Ceiling height, window spacing and flooring direction on the main level all set a rhythm, and a new room that follows that rhythm feels like part of the original floor plan instead of a separate structure.


Looking at the addition from the street and from the yard is the best test of a design. Placing a bedroom or sunroom where the rooflines can meet naturally usually produces a cleaner result than forcing a footprint that fights the existing shape of the house, and it leaves fewer awkward valleys to maintain.

How a Home Addition Ties Into the Existing Foundation and Roof in Camas, WA

Everything about an addition depends on how it is joined to the house. The new foundation has to be tied into the existing one so both settle together, and the footing depth, reinforcement and connection details are laid out in the drawings before anyone digs. A foundation set beside the old one can crack at the joint.


The roof is the second major connection. Tying a new roof into an existing one means planning where the two planes meet, how water drains across the valley, and how flashing and underlayment overlap. A valley with poor flashing is where leaks tend to start, so the roof design deserves as much attention as the room beneath it.


Walls and floors complete the picture. Where the old exterior wall is opened, the framing around the opening needs proper support while it is cut, and the new floor should land at the same height as the old one so there is no step or slope at the doorway. Questions about these joins are worth asking before any contract is signed.

Frequently Asked Questions

    Can an addition be built over an existing garage?

    Often yes, once the garage walls, footings and roof framing have been checked for the extra load. We evaluate the structure first, then tell you whether the plan can build upward directly or needs added support before any drawings are finalized.



    What should I gather before our first meeting?

    Bring photos of the house, any plans or surveys you have, and a list of what the new room needs to do. Notes about how your household uses space day to day help us shape a design that fits.



    How do you protect my yard and landscaping during construction?

    Access paths are marked, materials are staged in one area and plantings near the work zone are protected. Before starting, we walk the property with you to point out anything that matters, and we clean up at the end of each work day.



    Does it make sense to update the rooms next to an addition?

    Updating them usually does. When the new room opens into an existing one, matching flooring, paint or trim at the connection looks best, and planning the adjoining space during design means both parts come together instead of being added later.



    How is the opening between the old house and the new room planned?

    Width and height are set during design, based on the structure above, and usually a beam or header carries the load. We decide the size with you so the connection feels natural and supports the framing.



    What size should a sunroom addition be?

    Size depends on how you plan to use it. A reading nook needs less space than a dining area or family lounge, so we sketch furniture layouts first, then set the footprint to fit comfortably with room to move.



    What if the siding on my house is no longer made?

    Closest available profile and color comes first, and we also consider replacing the connected wall so old and new surfaces read as one. Seeing samples held against the house helps you decide with confidence before any siding is ordered.



    Can an addition be built close to mature trees?

    Yes, with planning. We look at root zones, canopy height and drip lines, then adjust the footprint, foundation type or roof design as needed so the addition and the trees can coexist without damage to either.
