Thinking about expanding your home? You’re not alone. In a place like Mountain View, where space is tight and moving isn’t always the best option, a smart home addition can seriously change the way you live. At Intelligent Choice Builders, we build large, high-quality home additions that feel like they’ve always been part of your house. From second stories to guest houses to open-concept kitchen expansions—we’ve done it all, and we do it right.

Why Add On Instead of Moving?

Home Addition Contractor Mountain View

Let’s be real—buying a bigger place in Mountain View isn’t cheap. If you love your neighborhood but need more space, a well-designed addition is the perfect move. Not only do you get to stay where you are, but you’re also adding serious value to your property. Want to see what’s trending? Check out the latest renovation styles homeowners in Silicon Valley are loving.

Top Reasons Homeowners in Mountain View Are Building Up (or Out)

  • More Room to Breathe: Add bedrooms, a bigger kitchen, or a chill space for the family to hang out.
  • Higher Home Value: Quality additions pay off—especially in a market like Mountain View.
  • Space for Everyone: Need a setup for in-laws, parents, or adult kids? We got you.
  • Work-from-Home Ready: Skip the dining table setup and get a proper home office built in.
  • No U-Hauls Needed: Keep the same schools, neighbors, and zip code—just with more space.

What We Build in Mountain View

We handle everything start to finish—design, permits, construction, final cleanup. You dream it, we make it happen.

Second-Story Additions

Running out of room? Go up instead of out. We build strong, seamless second-story additions that double your space and still look like they were always part of the original home. And yes—we’ll handle all the city red tape so you don’t have to. Learn more about the zoning rules you’ll want to know.

Master Suites That Actually Feel Like a Retreat

We’re talking spa vibes—walk-in closets, open bathrooms, natural light, and maybe even a balcony if the lot allows. Want to see how to brighten the space? Check out our natural light tips from Los Altos projects.

Kitchen + Dining Room Additions

If your kitchen feels like a squeeze, we can open it up. Think: a massive island, more storage, open flow to the backyard. Functional, beautiful, and built to entertain. For extra inspo, our Sunnyvale garage conversion guide shows how to make the most of underused space.

Guest Houses & ADUs

Whether it’s for guests, family, or rental income, we design ADUs that actually feel like a home—not just an afterthought. We know the Mountain View permit game and we’ll handle the entire process. Related read: cool ways people are using bonus space.

Living Room & Media Spaces
