Get The Inside Scoop From A Team Who's Built
A LOT Of Solid, Long-Lasting Additions

NIB has been a go-to crew for home additions in the Service Area since 2011. After enough of them, you see the same patterns – more living space, bigger kitchen or bathroom areas, new upper-level rooms – and our accountability means each one gets the same steady approach.

So, What Are The Four Addition Types We Build
Again And Again In The Spokane Metro?

If your plans are up to code and everything works mathematically, we can build it – from small backyard offices to Custom Home Building. Most of our addition work falls into four main categories, each backed by our Full-Time Project Presence.

Room / Bump-Out Additions

Maybe all your home needs is more breathing room – an extra bedroom, a larger family room, or a bump-out. We tie in everything cleanly so it feels like it was always meant to be there.

Kitchen / Bathroom / Suite Additions

Kitchen and bathroom additions are usually for families who need more function out of their homes. Whether expanding a kitchen, adding a bathroom, or building a primary suite, we focus on solid construction and clean integration.

Vertical Second Story Additions

Second-story additions give you a major boost in living space without sacrificing yard space. These projects take experience and careful planning, and we make sure everything fits your home's layout, load requirements, and long-term durability.

Outdoor / Accessory Additions

Sometimes you need a sunroom, enclosed porch, backyard office, or accessory structure that extends how you use your property. We'll build it with the same care and craftsmanship — functional, sturdy, and built right.

What Are The Basics Of Building A
Home Addition With NIB?

Behind the scenes, we're dialing in elevations, tying structures together, and matching exterior details so everything lines up clean. Here are the real on-the-ground basics.

Get Floor Elevation & Foundation Right

The toughest part is making the new floor meet the old floor perfectly, so we scout your property, shoot elevations, and figure out exactly how deep to excavate and how the foundation needs to be formed. We take our time and get it dead-on.

Tie Rooflines, Walls & Structure Together

Now we frame to match your home – roof pitch, eave height, structural layout – weaving the new roofline into the existing so it sheds water right and looks seamless. The wall tie-in is the same deal – it all has to hit perfectly.

Match Materials For That "Original" Look

Now we blend the exterior, matching siding, trim, windows, and roofing so nothing stands out as new. Whether it's a backyard office, she-shed, or suite addition, the goal is a space that looks like it's always belonged to your house.

Why Do Spokane Homeowners Choose NIB
For Their Additions Projects?

Most folks call us because someone they trust said we could handle it, and that's how we've grown – one referral at a time. We show up, do it right, and keep most workmanship In-House.

Additions demand steady, detail-focused builders – you're tying a new structure into an existing house with zero room for guesswork. Our crews take ownership, stay present, and make sure every piece lines up.

We don't sell or push. We build what you need and do it well.
