The cost of a home addition varies significantly because every property and project scope in our region is unique. For a high-end design-build project in Central Oregon, a ground-level addition such as a primary bedroom or a refined sunroom typically starts at $150,000 or more depending on the square footage. A second-story addition over an existing garage can also start around $150,000 because the primary structure is already in place. However, adding a full second story across the entire home is a much larger undertaking that generally ranges between $300,000 and $500,000 due to the complex structural work required to reinforce the foundation and walls.

Several factors influence these final figures, including the size of the new footprint, the specific structural needs of your home, and the level of finishes you select. Projects that involve "wet" rooms like kitchens or luxury master baths will naturally be on the higher end due to the plumbing and electrical infrastructure involved. Additionally, the age of your home may require modern upgrades to your existing electrical or HVAC systems to safely support the new square footage.

If you are unsure how large of an addition your specific lot can handle or what is actually feasible for your budget, feel free to contact us for a free on-site consultation and estimate. We will go over the specific details of your property and help you see exactly what is possible for your home before you begin the design phase.

The size of your addition is generally limited by lot coverage and floor area ratio rules specific to your zoning district. In some cases, you can actually build multiple additions, such as a new garage with a primary suite above it and a separate kitchen bump-out, as long as the total footprint stays within the legal limits for your land. We can help you navigate these size considerations and see if your vision fits within local codes during a free on-site visit.

If you are unsure how large of an addition your specific lot can handle or what is actually feasible under current Deschutes County guidelines, feel free to contact us for a free on-site consultation and estimate.

Yes, any project that involves structural changes or adding square footage requires a building permit. If your home is within the city limits, you will work through the City of Bend Online Permit Center. For properties throughout Deschutes County, the process goes through Deschutes County Community Development. Because additions are considered permanent livable space, they must meet the 2023 Oregon Residential Specialty Code. If you are feeling overwhelmed by everything and don’t know how to get started, feel free to contact us for a free on-site consultation where we can help you understand the permitting roadmap for your specific lot.

It depends on the scale of your project. For smaller additions like a single room "bump-out" or a modest sunroom, your existing systems can often be extended to cover the new space. However, for larger projects like a primary suite wing or a second-story expansion, your current furnace or electrical panel may not have the capacity to handle the increased load safely.

If your main system isn't large enough to support the extra square footage, we often recommend installing a ductless mini-split system. These are incredibly efficient for the Bend and Sunriver climate because they provide independent heating and cooling specifically for the new addition without straining your central unit. During our initial on-site consultation, we can evaluate your current infrastructure and help you determine if a simple extension or a targeted upgrade is the most cost-effective path forward.

If you aren't sure what your property can handle or want to see what is possible for your home's systems, feel free to contact us for a free on-site consultation and estimate. We can go over the technical details and help you plan the most efficient way to power and heat your new space.

Solar setbacks are unique to the Central Oregon Area and are designed to ensure your new addition doesn’t block a neighbor’s access to sunlight, particularly from the north property line. These rules can dictate how high or how close to the property line you can build. You can research the specific "Solar Standards" for your zone through the Deschutes County Zoning 101 guide. If you are worried that a second story or a large extension might violate these rules, our team can perform a site assessment during a free consultation to see what’s possible for your property before you start the design process.

Our primary goal with any home addition is to ensure the new structure connects seamlessly with your current house so that it never looks like an afterthought. We take great care in matching your existing rooflines, siding textures, and window styles to maintain the original character of your property. However, for older homes in particular, the most effective way to achieve a perfect match is to perform the addition as part of a full home remodel. By updating the entire exterior and interior at once, we can ensure every finish and detail is consistent across the whole structure, which can be more cost-effective than trying to match decades-old materials piece by piece and then remodeling a couple years down the line. 

Whether you are looking for a standalone expansion or a complete transformation of your property, our design build team focuses on creating a cohesive flow between every space.
